Cant Reference Dynamically Generated Iframe In FF?
Apr 14, 2011
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');
[code]....

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.

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?

I keep getting this error during validation reference to entity "src" for which no system identifier could be generated ludes/phpthumb/phpThumb.php?w=1000&src=../../../../images/stories/portfolio/it This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details., followed by entity was defined here /includes/phpthumb/phpThumb.php?w=1000&src=../../../../images/stories/portfoli� the ampersand is bold and red, highlighted if you will.
Then it shows reference not terminated by REFC delimiter cludes/phpthumb/phpThumb.php?w=580&src=../../../../images/stories/portfolio/it If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.

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.

Does anyone know how to make this work?
var sectionId = 5;
repeat_section_sectionId();
function repeat_section_5(){
alert("firing");
}
The function's name contains the variables value, so how do we make
the engine see that?

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.

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):
Code:
counter++;
// Find the element to be copied

I am dynamically generating javascript arrays in my custom tag
This is the java code
autoCompleteResult += "<script> var valuesInListOf" + displayProperty + " = new Array();";
I can see this variable in debug on client side in javascript, just not sure how to access it.
in javascript
var values = "valuesInListOf" + displayProperty;
this gives String variable whereas I want to access JavaScript Array that I created in my tag.

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 see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.

I've been bashing my head in a vain attempt to achieve the desired result... i.e. having the ability to catch an event inside of an iframe, generated by CKEditor... all in all, I've tried numerous ways to reference the iframe itself, and I've managed to succeed... though catching an event still remains a dream. Google turned out to be less than helpful and well.. CKEditor's own event listeners really don't do a whole lot of good either (Not for me anyways). The code is being tested with the sample provided with the plug-in... for double-click on div to begin editing it. Here is the code I have at the moment:
iframes = document.getElementsByTagName("iframe");
iframes[0].contentWindow.document.body.onkeypress = function () {
alert('Event caught!');
}
Obviously, the alert is there for testing purposes, but so far I've been unable to get it to fire.

I have an iframe that can successfully reference its parent window, using the following code:
var elm = window.parent.document.getElementById('iframesID');
This works flawlessy in all browsers, EXCEPT for some reason, Safari 5 on Mac (Safari 5 on Windows works fine).
After debugging a bit, I found that the script breaks exactly on that line, and alerting the value of window.parent returns undefined. Going nuts! I Googled this specific question way too long and found no responses.

I have form elements which dynamically generated like this...
<form name="formA" ...>
<input type="select" name="text_1" ...>
<input type="select" name="text_2" ...>
<input type="select" name="text_3" ...>
<input type="select" name="text_4" ...>
</form>
And I doing some validation like this.
function checkvalue()
{
var f = document.forms['formA'];
var eLen = f.elements.length;
for (var i=0; i<eLen; i++) {
if(f.elements[i].name == "text_" + i)
{ alert ( f.elements[i].name); }
else { alert (f.elements[i].name); }
}
It never goes into first part of if statement.. Is there a way I can
access these kind form elements..

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.

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?

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.

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()'

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):
Code:
scr.parentNode.insertBefore(newNode,src);

I'm using a javascript to alternate table rows and it works fine by table id, and on the first loop. This is all inside a conditional, in which the table tag is repeated.
On the second and subsequent loops, the alternating row color fails because there can only be one unique id call to a page. Right?
What's the script that will allow unlimited reiterations of tables with alternating row colors, using class?

Im having problem generating the labels for content created by the following function:
function setOutput(){
if(httpObject.readyState == 4){
var answer = httpObject.resultsponseText.split(",");
var results = document.getElementById("resultsultadosScan1");
var article = document.createElement("div");
var weight = document.createElement("div");
var price = document.createElement("div");
article.className = "article";
weight.className = "weight";
price.className = "price";
document.getElementById('outputText0').value = httpObject.innerHTML= answer[0];
document.getElementById('outputText1').value = httpObject.innerHTML= answer[1];
document.getElementById('outputText2').value = httpObject.innerHTML= answer[2];
article.innerHTML = httpObject.innerHTML= answer[0];
weight.innerHTML = httpObject.innerHTML= answer[1];
price.innerHTML = httpObject.innerHTML= answer[2];
results.appendChild(article);
results.appendChild(weight);
results.appendChild(price);
}
}
A friend wrote this sample script to achieve generation of labels on my script, but I have been trying for hours with no luck, can someone take a look and tell me the correct usage of this script:
Code:
function createLabel() {
var target = document.getElementById("target");
var label = document.createElement("label");
var text = document.createTextNode("Article");
label.appendChild(text);
target.appendChild(label);
}
Can you help me with the correct "combination" using my script above, a "real life" example?

I've got the following javascript, which loads the site [url]... with a random string after a forward slash [url]...
At the moment, this presents a button which opens this URL in a new window. But I'd like to instead load this JS generated URL in an iFrame. I figure I need to stick something after the iframe src= that calls on the output of the javascript.

I simply need to reference an object inside an iframe:
I need it to work on all browsers as I understand this is difficult for this type of command.
Why does the below code not work in ANY browser let alone all of them.
I have tested in IE8 and FF3 (not IE7).
file1.html

<iframe name="iframe1" id="iframe1" src="file2.html"></iframe>
<script>
parent.iframe1.form1.obj1.disabled=false;
