JQuery :: Setting Background Image To Another Div's Dynamically Generated Image?

May 12, 2010

I have a div set up like this

<div id='y' style='background-image: url(./randomcolor.php?ibase=
<?
php echo $entity
->

[code]....

I am having an issue with setting the background-image of a another div #x to the background image of #y.Correct me if I am wrong but I think you would do this in a simple case by saying

$
(
'#x'
).

[code]....

So when it does it, it is getting the URL of the generator (I logged it. what is actually being passed is [URL] This would require a server call to generate a new image, In this particular application, even if it wasn't exactly the image y had it would be acceptable. But it's not doing it. It is not getting any image at all. Am I doing something wrong, i.e. is it supposed to just work? I would think not, since the page has already been rendered. This is almost an ajax situation but I don't know how to do it for an image. I don't really want to generate a new image anyway, I'd be very happy to get the one that's already there. How would I access the actual image already attached to y and not do another server call?

Dynamically Inject Multipart MHTML Content Into Document?

Sep 15, 2009

Serverless situation where applet drives document scanner and captures images. Currently use data uri technique <img src="data:image/jpg;base64,BLAHBLAHBLAH> to dynamically change img src (image fed from the applet) when user wants to view a particular image.

Works great in firefox...In ie8, however, the 32K limit on data uri's stops me cold.

I researched switching over to MHTML techniques for IE only....but without server-side generation of the MHTML (or CSS), I am running into issues.

Does anyone know of a way to dynamically 'inject' MHTML content via javascript into current document for use as MHTML image ?

JQuery :: Using AJAX To Inject Html But What To Inject To Get Css Applied To Requested Html?

Nov 8, 2010

I'm using jQuery AJAX to request html pages so no refreshes will be needed when someone clicks an menu item. But the things is, I'm currently requesting HTML pages with no doctype, head and body tags.. just only the content (with just h1 tags and tags like that). The problem is that when I inject that into an div on my main page the css doesn't get applied to the injected content. It does set the text color and makes H1 an heading but it doesn't apply specific things like h1:first-letter. So I'm assuming it only applies general css properties like the text format I applied to the body of the main page. So the question is how can I make the css apply to the AJAX requested and injected content? Should I include an css file to the file I'm requesting? Should I use some jQuery function to apply it after the injection? Or .. ?

Dynamically Change Row Colour On Dynamically Generated Table Rows

Nov 25, 2005

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.

Sample of code I am using:

Code:
var tbody = document.getElementById('tableItems');

var row = document.createElement("tr");

var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}

var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.

Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?

Or is there just something blatantly wrong in my approach?

JQuery :: Get Dynamically Generated ID By Class Name?

Sep 1, 2010

I'm stumped on a jQuery related development task. I'm using jQuery in a SharePoint Web Part...The web part pulls data from a list and displays each item as a link button. When the link button is clicked it uses the jQuery-UI to display the body of the list item in a dialog box. I have this working perfectly when all of the class names are hardcoded. So in this code dialog0 is the class name for the body of the first article. newTitle0 is the linkbutton so they correspond 1:1 (and so on Dialog1, newsTitle1 etc..)

$('.dialog0').dialog({
height: 500,
width: 990,
autoOpen: false,

[Code].....

Problem is, when I have more than 1 instance of the web part on a page, because they use the same class names (2nd web part would also use Dialog0, newTitle0), if I click on an item in one web part, the item with the same class name opens in the other web part as well.

I've implemented it so each item now has a unique ID but I don't know where to go from here, so multiple instances of the web part can be on the page, and have the jQuery know which body to display when a link is clicked.

JQuery :: Reload Content In A Div That Is Generated Dynamically?

Oct 22, 2010

I have a jsp file that is used to display data from Java objects running on my server. I'm using JQuery for tabs and to handle the ajax calls to a servlet that affects the Java server I have running.Each tab represents a service, and has a corresponding java object on the server side. These are generated from the spring configuration, and is working fine. The page is used to control some aspects of the service, and I have a few buttons that can be clicked. I'm trying to get it so that when a button is pressed, the appropriate Java function is called on the service's object (this happens using ajax) and then refresh the current tab.

My js code is like this:

function doPause(params) {
//some additional params set
doAjax(params);

[code]....

Right now, I'm using the window.location.reload(true) to refresh the whole page but I'd like to just redo the div for the tab that contains the button that has been clicked.I have tried:

$("#"+params.client).load("monitor.jsp#"+params.client);

instead of the window.location calls above, but that puts the whole page into the tab.

JQuery :: Validating Dynamically Generated Fields

Dec 3, 2010

I'm trying to validate a set of dynamically created field names, for example

Name: <input type='text' name="s1[name]" id="s1[name]">
Image: <input type='text' name="s1[image]" id="s1[image]">
Name: <input type='text' name="s2[name]" id="s2[name]">
Image: <input type='text' name="s2[image]" id="s2[image]">

[Code].....

There can be any number of 'groups' but I would want to apply some validation for each item in a group. I can only see that the validation is done by specifying a id? however as the id's are going to be dynamically created how can I do this? can you validate for a css class?

JQuery :: Accessing A Form In A Dynamically Generated Iframe?

Jul 16, 2009

I am trying to write a Greasemonkey script using jQuery to automate various processes on a web site. One of them involves automatically filling in a form located in a dynamically generated iframe. When the frame is generated I can do $('#NewFrame').length and get 1 confirming it is now available. However, when I do $('#NewFrame #TheForm').length I always get 0 even though I can clearly see the form there in the iframe.

JQuery :: Selecting Objects In Dynamically Generated HTML?

Jun 3, 2009

I'd like to do something like this: After the page is loaded I have some forms with submit buttons. The buttons have a class called "open". By clicking any of these buttons the script is using AJAX to take some data from database and add some HTML to the document. This part of generated HTML has also buttons with a class "open". By clicking any of the new buttons script should do what it does with the old ones. The problem is I have no idea how to "refresh" a click function. After generating HTML it "sees" only the old buttons.

Here's some code:

$(document).ready(function(){
$(".open").click(function(){
var idVal = $(this).parent().parent().find("#PlaceId").val();
if($("#admin_places_"+idVal).html()=='')

[Code].....

JQuery :: Capturing A Dynamically Generated Set Of Input Data?

Aug 28, 2011

I've got a form that dynamically generates sets of input elements. First there is a set of up to 99 parent elements, and then the parents can have up to 99 child elements each. My question is not about the generation, but about capturing the data once the form has been filled out.

I made a script that handles getting the values and putting the values, along with their input id in an object that is used later. I don't want to have to use css classes or other attributes to identify the input elements, and wondering if that being the case, if I could get a critique of my script:

Edit this Fiddle - jsFiddle - Online Editor for the Web (JavaScript, MooTools, jQuery, Prototype, YUI, Glow and Dojo, HTML, CSS)

The output (the object) logs to your console when you click anywhere in the Result area.

JQuery :: Retrieve String Dynamically Generated On The Server Side?

Dec 16, 2010

From WebForm1.aspx, I have successfully retrieved a string that is dynamically generated in WebForm2.aspx and spit out to a Literal control in a div. This is what I did.

//In WebForm1.aspx, I have:
$.post("WebForm2.aspx", { para1: "value1", para2: "value2" },
function(data) { $("#mydiv").html($("div#div1", data).html()) });

That's pretty simple and easy to understand for you jQuery gurus out there.

Now, I am trying to do the same thing within the single web form. That is, in WebForm1.aspx, I have this jQuery script to post to the same web form (i.e., WebForm1.aspx), but it is not working. Postback works OK, but I am not able to retrieve the dynamically generated string and spit it out to mydiv.

What's the jQuery way to do this? Any example? I searched, but I've only found examples which try to get static string values, which I know how to do.

JQuery :: Linking A Dynamically Generated Span Tag To A Click Event?

Feb 7, 2011

I'm making an ajax call to my server and then, with the information I get back,ynamically creating HTML with jQuery, then appending it to my desired div. This part works excellently. The issue I'm having trouble with is I'm only returning five records, so I'm creating a span at the bottom labeled "see all", but even if I give that span a class,it's clearly not registering in the DOM because when I click it, my jQuery code doesn't even know it's there.My question: How do I get those dynamically generated elements to register in my DOM so they can be called by a jQuery click event?I realize that I can just do an inline javascript call to my function and that works fine(ish). The problem is, however, I want specific information about the particular span that I click, and if I call it inline, it doesn't send $(this) to my function... it recognizes $(this) as $(window), not as $(span that I clicked)

I am using the Collapsible Checkbox Tree jquery Plugin.For that I have inserted this linein the javascrypt code:

When I make a list in the HTML code using the <ul id="example"> works perfectly.

But when I tried to make the list dynamically calling a JSON file, does not works fine.

If I insert theready(fn) mentioned above inside the javascrypt function that create dynamically the element<ul >as is shown next:

Improves a little bit, but still does not work fine. Specifically does not show the plus and minus sign, then I can not open or collapse it.

I tried also with thecheckboxtree pluginand I encountered the same problem.

JQuery :: Adding Color Effects To Dynamically Generated Form Fields?

Nov 21, 2010

I'm having some trouble with my dynamically generated form fields.

As you can see I'm generating new form fields, but the problem lies within the grade field. I have it set up now so that when you change the grade the color of the <select> box changes relative to the grade. A-D are green, F is black with white text, Not Taken is just regular white with black text and In Progress is lightly shaded grey.

I want it so that each one can be changed individually, but I can't seem to be able to figure out how to do that. Heck if you change the first one's grade field, that colour follows the rest of the clones.

This is the jQuery I'm using to change the color of the thing.

$("select").change(function()
{
$(this).each(function () {

Php, Sql, And Dynamically Generated Listboxes?

Jan 19, 2011

I want to dynamically generate list box options using the content of an sql database in real time. More specifically, i have a page with a couple of listboxes, when i click on an option in the first list box, i want the second list box to update with options that reflect the first one, in real time generated by the sql database.now i was wondering if it might be possible for javascript to send some thing to php which php could decode and search the database and return the results of that search. here is how i imagine the process to look in psudeo code:- user clicks on an option (say the 3rd option) in the 1st listbox- javascript catches the event, and sends some data to php indicating the 3rd option from the 1st listbox has been clicked- php tells sql to search for records that correlate with the 3rd option from listbox 1- php sends search result back to javascript- javascript populates the 2nd listbox with search resultsi want to do this with out having to refresh the webpage, security issues aint high, cause this project probably aint gonna go on the web. I got the idea from the dynamic searching on google, so i guess such technology is possible some how.

Loop For A Dynamically Generated Form

Jan 4, 2008

Here is the code:

function selectDefaults(buttonGroup){
for (i=0; i < buttonGroup.length; i++) {

if (buttonGroup[i].checked == true) {
for (count=1;count < document.addForm.recordCount.value; count++) {
var doc = document.addForm.feature1[i]
var featureVal = doc.value;
featureVal = featureVal.substring(0,2);
if ( featureVal == "SF"){
doc.checked = true}
} }}}

I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....

How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i]
which gives me a syntax error.

The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.

I can reference one called 'footer' that is created in the same line of code as the other IFrames however (oddly enough). I've tried numerous ways with no luck. Since this is inherited code and designed years ago to run on IE only it's a mess. You'll see I've tried alerting out various different ways and simply left it in to show my feabile attempts.

Storing Text From Dynamically Generated Output?

Jan 23, 2011

I have script that is dynamically generating updates on my page. The code is this:

Code:

<a id="cc_stream_info_song" target="new">Loading...</a>

The id tag links to a js script on a remote server and replaces the "loading" text with the song title of the currently playing song on my shoutcast server, and refreshes this every 60 seconds. I want to be able to grab this song title and put it in a php variable. I don't have access to the remote server, so I don't have any other way of getting the updated song title outside of this little snippet. I tried using php output buffering but all that does is grab the html I posted above, and not the javascript-generated song title.

Add An OnChange Behavior To Dynamically Generated Field

Apr 26, 2007

I want to add an event to a generated SELECT field. It's an onChange call to a function named calculateSubtotal(). The result I want would look like <select name="..." id="..." onChange="calculateSubtotal()">.

This is what I've got so far. The drop menu is created with no error, but no onChange either. Code:


var newTour = document.createElement('SELECT');
newTour.name = 'registour' + rowCount;
newTour.id = 'registour' + rowCount;
var newAttrib = document.createTextNode('onChange="calculateSubtotal()"');
addOption(newTour, '');
addOption(newTour, 'Tour 1');
addOption(newTour, 'Tour 2');
addOption(newTour, 'Tour 3');
document.getElementById('groupreg').appendChild(newTour);
document.getElementById(newTour.id).appendChild(newAttrib);

I also tried this, it doesn't work either:
newTour.onchange = 'calculateSubtotal()'
