Dynamic Onchange Not Working
Mar 28, 2006
I've got some javascript that adds in form elements after a page has loaded. The checkboxes need an onchange event added to them which will call a function. However, if I enter the function call against the onchange event it doesn't work, if i enter the full function against the onchange then it does. Hard to explain but here's the working and non-working Code:

For some reason my change() function is only called when the page loads. I'd
much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() {
var new_select = new Selector('tdata','myselect','myid');
var new_select_list = new DataSource("some_list");
new_select_list.addItem(1,"One");
new_select_list.addItem(2,"Two");
new_select_list.addItem(3,"Three");
new_select_list.addItem(4,"Four");
new_select_list.addItem(5,"Five");
new_select.setDataSource(new_select_list);
new_select.formInput("form","input");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
<td>
Select:
</td>
<td id=tdata>
</td>
</tr>
</table>
</form>
</body>
</html>

getting dynamic rows inputs to multiply 'onchange' of the value in the input in each row. It works in the first row inserted no matter what rowindex that row is moved to. All following rows only accept the initial input value and never change the 'cost' innerHTML of the colRow[i]. I figure I need a parentNode.parentNode syntax to make this function work in all rows.
Every thing is Client-side javascript and all rows are inserted to 'cartbody.insertRow[0]'. 'qtymultiply()' Function As is:
Code:
function qtymultiply(){
var cartitems=document.getElementsByClassName('itemrow');
var colRows=cartitems;

I have created some Javascript to make a form application dynamic. My problem is that the code works in every browser except for internet explorer. I get no errors from Firebug and I have made sure that internet explorer has javascript enabled. I am completely in the dark as to why this would be happening. It works perfectly in Firefox, Chrome, and Safari. Here is my entire code for the form, it is for a housing application for a college,
Code:
function runAll2 (processPart, areaType, spaceType, mealType) {
pp = document.getElementById('fld2416');
at = document.getElementById('fld2417');
st = document.getElementById('fld2418');
mt = document.getElementById('fld2481');
[code]....
This for is supposed to go live on Tuesday and I didnt realize that it wasnt working in IE until today. I am pretty good at HTML and CSS and know a bit about cross browser testing, I just didnt even think about it because this form is entirely ASP and Java, my bad.

I have a select field that has an onchange attribute that fires an ajax script to fill out another field. It's working perfectly in every browser except IE, but I just cannot figure out why it's not being triggered in IE. Code:

In JavaScripts checks for an onChange event against the value of the
textbox at the time of the last onChange event. Since an onChange
Event never fired after you changed the text first time , suppose we
put the same value in the text box then no event is fired.
If we put some other value then it became fired...
It wouldn't fire if we put the same value...
I don't want to use onBlur etc... Isthere any solution with onChange
Event...?

I have a dropdown that when the user selects an item, a function is called. Right it is giving me an error of 'object expected'. Can someone please take a look at my code below and let me know where I am going wrong? When I change the filldesc to an alert, it works fine and returns the correct values.
function filldesc(inputlevel1)

I have the following code which works fine in FF but not in IE. code...
In FF, when you change the Fund dropdown to be Romanian Floods, the location dropdown disappears and the location_box text box appears which displays the second part of the value (Romania). If you select another value from the Fund dropdown again, this box disappears and the location dropdown box would appear again. This is exactly what I need it to do.
In IE, whenever you select anything in the Fund dropdown (doesn't matter whether it is Romanian Floods or anything else), the value in the Fund dropdown disappears and thus when I press submit it doesn't work!

So I have a form with three drop down boxes. When I select a value in the first drop down box, the options for the second dropdown box are retrieved from a PHP script via AJAX. Likewise, when I select a value in the second dropdown box, the options for the third are also retrieved via AJAX. This is done with an onchange handler. You can see how this works at the following: [URL] That works perfectly. I run into problems later however when I try to change the value in one of the dropdown boxes with Javascript.
See, I have a text field that a user can enter a string into (this feature is not in the sandbox at that URL yet), and that string will then be used to populate the dropdown boxes. For example, if the user enters "subject-genus-dog", then "subject" should become selected in the first dropdown box, "genus" should be selected in the second dropdown box, and "dog" should be selected in the third. The problem is, the onchange handler doesn't seem to trigger when the value of the first dropdown box is changed to "subject", and thus the second dropdown box does not get populated with options via AJAX, and so "genus" cannot be selected because the only option in the second dropdown box is the default "select a value in the first box".
Why doesn't the onchange handler trigger when a dropdown box is changed with the following code? [code=text]document.getElementById(destination).value = reloadValuesSubArr[1];[/code] Is this a bug in Javascript? Or am I doing it wrong? Keep in mind that the value of the first dropbox changes without issue, but the onchange handler does not trigger.

I have two radio buttons. When their value changes the form is resubmitted. In other words, when you select the other one, the form is resubmitted.However, in internet explorer, it takes two clicks. The first click is to change the radio button (it has to be changed) and the second is to select the other one (it has to be changed, again). The form remembers the first change. Edit: You can click the unchecked radio twice and it will also submit. Usually.I'm not even sure if this should go here or HTML but I think here is the better options since I am, after all, dealing with javascript.
Code:
<table id="..." class="radio">
<tr>

I recently learned that the <option> tags can not use the onclick attribute inside of IE.This works great for firefox, but sadly not a single version of internet explorer supports it (from what I am told via countless Google searches).I have been modifying my attempit at a solution to use the <select> tag with the attribute onchange. Maybe I am casing this wrong, or not seeing a solution as the below code does not operate in any browser, and no errors are reported back through firebug or IE.Excuse my sloopy attempt at {smarty tags} this script is written in a bunch of PHP object->vales and to save space cored the issue down to it's basics.On change of the select box, the value="5-28" is sent to javascript showBox to split the number away from the id_trips and only focus on the locations (the number before the '-' . IF the location matches the switch value then the box should show / hide or value change. The IDs are all correct I just think that there is a ' or a " or something off as I am not a javascript expert.

//PHP VARIABLES from QUERY sample loop 1

Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.

Actually the below code only creates dynamic DIV in IE, but for Firefox it does not create any DIV. Also it does not create the event onclick to be triggered when clicking on any area inside the DIV.
I want to create dynamic DIV in firefox and IE + I want onclick event when clicking on the DIV as I want to that click to delete the content of the DIV or you can say collapse it.

I'm frustrated :(. I've been trying to get this single piece of code to work. I've looked at quite a few sources out there, but everything I try fails. My site uses AJAX to upload a file, and once complete I dynamically add the file name, size, description, etc to a table.
I have a javascript method that will allow me to download the file once uploaded - and I put an onclick event into some of the TDs in the row I added. (Note: I didn't want to put it in the TR because I also have a delete button in the row).

I'm trying to create a dynamic drop down box where the first drop down box populates the second drop down, but it isn't working. I have two tables; pricelist with fields,
-id
-groupname
-item
-price
groups with fields,
-id
-groupname
I've got the code and to me it looks as though it completely works, but i think its the fact that two of the fields have the same name, and it's causing problems.

Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.

I have a page with a large centre-aligned image on it. I want a
functionality whereby users can click their mouse on any point in this
image and it would then show a virtual mouse pointer at the place where
they clicked it. If they were to click somewhere else, the position of
the virtual cursor would change.
The position of the cursor needs to dynamically generate a link and
display it in a form field text edit box.
If that link is then viewed separately, it would launch the same page
with the virtual mouse pointer at the location where the original
person placed it.
Basically I want to be able to have one guy point to a location on the
image for the benefit of another guy, but graphically as opposed to
relying on written explanation.

If the user types "a" then the select box is populated with "Choose An Animal...", then the three three animals beginning with A. So far so good. But if the user selects say Albatross and then types the letter b then the option "Bear" is selected rather than "Choose An Animal". Although the code is sel.selectedIndex = 0; (not 1). How can I force the selected index to 0 when a choice has been made previously? Is this a bug - if so it is the same in IE and FF.

Just working on this page - [URL]
In Opera, the dynamic resize of the iframe isn't working correctly. As you can see in the code, I have set a minimum height of 200px so the iFrame should always be a minimum height but if the content requires it will increase. It works fine in IE8, Safari, FF, Chrome but not in Opera. In Opera it just sets the height at 200px.

I'm trying to create a dynamic table with onclick event like this but onclick event seems to do nothing:
var srcTable = this.iContext.getElementById("tbody");
var tmpRow = null;
var tmpCell = null;[code]...
I found a few examples like this: tmpRow.onclick = function() { alert(this.rowIndex);};
but I need use selected data, maybe call a defined function. I already tried lines bellow but nothing works, because doSomething is not function of tmpRow object.
tmpRow.onclick = function() { doSomething(this);}; or tmpRow.onclick = doSomething(this); or
tmpRow.onclick = "doSomething(this)";

When i try to dynamically change the height of an iframe in ie through a java-script to match its content (a html page containing a flash movie, it doesn't resize the iframe at first, but when i reload the same page into the iFrame it resizes as planned, how come?This script works well in firefox, safari and netscape, but i cant get it to work in ie(8, 7). And i get the same problems with every resizing script i've tried. This is the script i use:
<script type="text/javascript">
function adjustIFrameSize(iframe)
{ [code].....
I have a flash menu in the first iframe, the buttons on the menu uses getURL(siteToLoad, "contents") to load another html-page into the iframe "contents". Is it possible to make the iFrame refresh automatically though javascript so that i just refreshes the iframe once? Everytime ive tried that it just ends up in a never ending refresh-loop... How can i make this work? Is there any better script for resizing (and refreshing after resize) the iframe height so that it matches to its content?
