Add Dynamically Generated HTML After The Page Has Loaded?
Mar 14, 2009
I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) {
var newNode = createImageField(x);
var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).
On my webpage, I dynamically create an iFrame when a button is pressed, then load a html page from within my own domain into the iframe, based on what html page is loaded into a variable. My question is, can I dynamically change the font family of the loaded html page from the javascript of the main page? My code to create the iframe is:
function setSubTxt(){ var par = document.getElementById('parentDiv'); par.innerHTML = '<iframe src="'+subTxt+'" style="width: 375px; position: fixed; height: 365px; left: 400px; top: 145px; border=none;" name="subIframe" frameBorder=0></iframe>'; frames['subIframe'].window.location=subTxt; document.subIframe.document.body.style.fontFamily = "Arial"; [Code]....
the variable "subTxt" has the url of the html page to be loaded (always on the same domain). The code: document.subIframe.document.body.style.fontFamily = "Arial"; was my attempt to dynamically change the font, but it didn't work. Also, it should be noted that there is no font family set in the html pages which would override this.
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()=='')
OK, I am very new to jQuery so bare with me here. I am trying to get the document body height and set it as the height of a table, after the page has been loaded. Below is an example of what I am trying to do.
[Code]...
I am not sure where to place the jQuery code, before or after the table tag...and I am not even sure if any of my jQuery code is correct. Once again, i need to set the table height AFTER the document has been loaded and then dynamically change the height of the table.
I've been trying to get this page working with dynamically loaded iframe sources passed by URL, but I can't seem to get it working.Here's the relavent code:
<script type="text/javascript"> function delineate(str) { URL = str.indexOf("=") + 1;[code]...
I used the hidden form to change the url to text - advice from another website. I'm sure there are better ways to do it, but I'll explore them as soon as this thing actually works..The types are in a subfolder named types, as shown. The document.write was placed in as a debug helper, and it displays the proper file location of whatever I select with the combo box, but the iframe doesn't change it's src to the selected page! I've tired the last line of the last <script> with several different methods, none of them producing any effect whatsoever.
I am working on a page that will load in other pages using AJAX and the .html method. Something like this :
<span id = "edit">Edit</span> <div id = "cont"> </div> //the click edit script
[Code]....
Unfortunately this does not seem to work, entirely. It does trigger the click event but it messes up the post for some reason. I have played around with it for the last 45 minutes or so and it seems like the click event trigger is what is messing things up, if I comment it out it works fine. Could anyone tell me why they think this is? note this is an over simplified version of my actual code, but the structure is the same.
I am sure this question has been raised and answered before, but I can't seem to find an answer that works for me. I hope I will get an exact response here. Here's my issue - I have my index.html that has its own $(document).ready method and everything pretty much works within it. I am trying to dynamically load a page to replace part of index.html (let' say the #inner_content ID) -
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 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?
After a html document loads in a browser,I want to be able to monitor
the page incase any content on it changes for any reason.
Is there a Javascript function with which I can track 'what has
changed' on the webpage .
This should be irrespective of the type of content on the html page
I have two example for you to ponder on: Ex1: ----- Say in an html document there are two select boxes s1 and s2. The items list in s2 depends on selctions in s1 (page is not
refreshed..ie.. s2 is loaded through Ajax or sumthing)
So after the html page loads I need to get a notification whenever s2
is populated...
Ex2: ------- Say ,in a html page,there's a link,Onclicking which a light pop-up
div is created with some text. How can I capture the content of this dynamic pop-up?
In all this discussion,I'm not taking into account any particular
format of html...the html content can be anything.......I just need
to keep tracking if any content chages after the page loads...
Ideally I need to achieve this using javascript (client side
I have a page that inserts a div after another div on my page. Basically this div and its content are generated by the server and outputted via Ajax when the user clicks a button.I have something like:
//Listener function $("div").click( function () { alert("thing"); });
Clicking any of the divs that were loaded on the page will give this alert however, clicking on this div that was inserted after the user clicks a button does not respond to this listener. I put my rendered html into the w3c validator and my page has no errors (because I thought that maybe I had a missing end tag which would cause jquery to not work).
I'm running into a little bit of a problem with tinyMCE. My textarea is not loaded with the initial first page load but dynamically inserted in the DOM via ajax, so it doesn't display.
I've studied the documentation that comes with tinyMCE and it still kinda puzzles me what I have to do to "dynamically load" tinyMCE.
I have two problems that I suspect will be bread-and-butter problems for the more experienced guys on here, but I'm not the greatest with js.
NB: Code snippets at the bottom
The first problem is that after a bit of fiddling I'm getting am 'Object Expected' error when I click on the Depot dropdown which I can't seem to get round. The code I had was working OK but then I cut it all out, tidied it all up, and put it back in and now it doesnt work.
The second problem is a 'How do I...'. I'm using an XML data island to retrieve some data without submitting the form. In the first example, when the user selects a Customer, the Depot list is updated with all the depots for that customer; This all works fine. What I want to do now is retrieve some more data when the Depot is selected.
I have the XML bits working; the js code snippet correctly output a series of msgboxes with the correct value in (or at least it did until I introduced the Object Expect error!).
However, I'm unsure as to how to display this information on the page. The XML contains a series of Part No's and Quantities, which I'd like to display in a table towards the bottom of the screen. The problem is that I don't know how to dynamically create and populate this table.
The only caveat is that I dont want to show the table if no values are returned from the query....
i need to add n number of text box in a html page, the main idea is when the user press a button apear 2 text box and if he do it again apear 2 text box more and so on, also need that all the text boxes has a unique id, in order to make some thing whit the values. but i dont know how to do it.
I'm trying to add html controls dynamically. and I successful in that using clone method. But I lost my way I confused how to retrieve the values from the controls which I had cloned. Below is the simplified code i had done.
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.
Im wondering if generating html objects such as tabels and rows in javascript is faster than typing the html directly? Seems when you do it in javascript you have to download alot of code and would slow down displaying the page. while if you just type the html, it requires less bandwidth and display faster?
is parsing html to display in browser slower than doing it through dom to display the same html objects on the page?
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..)
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.
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):
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 cant seem to get the reference to the 'header' IFrame that is dynamically created. 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.
Code: function mit(e) { var iframeElement = document.getElementById('header');
There is a project called Seed which allows JavaScript programs to run on the Linux desktop. There is connected project called SeedKit which runs HTML files as a Graphical User Interface front end for JavaScript files run by Seed. It acts like a webpage which rather than linked to a web-server is linked to a JavaScript program with HTML events like buton clicks etc that drives JavaScript much in the same way as normal desktop Graphical toolkits do. I hope this page from my blog starts a bit.
http:[url]....
Both projects are quite new so is very experimental. I am not involved in the development of any of the projects but I am trying to create a few examples to show how it works. My first example is to take the contents of the log folder /var/log, display it in the SeedKit HTML file and when a user clicks on it, it displays the contents of the log file.The way I am going about this is firstly to create a two column table in the HTML thus:
<!DOCTYPE html> <html lang="en"> <head>[code]....
The table on the HTML file is populated with the file names but I can't get the contents of the specific div I have clicked on. I tried $(this).text() but it displays all the text in the table.
Many ajax and javascript functions change the innerHTML of elements in the source, writing and rewriting things in the source
You can run any javascript function or action you want that would change the source, but when you view it, it will always show the original source before a JS function changed it
Is there a way to view the changed source after each time a JS functoin changes it??
for example: <span id="whatever">This is the original source code</span>
then you may run this piece of JS: whatever.innerHTML= 'Changed source code!'
but when you right click and press 'view source" you will always get this: <span id="whatever">This is the original source code</span>
I want to get the changed source code, maybe its possible to write the changed source code to another file, or use some kind of HTTP prog to read the changes on an html page?
