I have a web-based form which allows users to enter marks for a group of examination candidates. I have a function which performs some calculations on the data as it is entered and displays it immediately. The data-entry form-part definition is:-

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:
View 9 Replies View RelatedIn 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)
{
alert(inputlevel1);
}

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:

I have written a javascript code which changes the combo_2 options on

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!
The onchange event is not working in Mozilla 1.5.0.2. Is this a Mozilla bug.
View 1 Replies View RelatedSo 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.

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.
View 3 Replies View RelatedCan 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.
In the next sentence, what's wrong?
<select name='id'
= 'Daniel Perez'&valor='+this.options[this.selectedIndex].value">
IE complains about missing ";"
I understand that the onchange event occurs when the value of a
form element changes (and after the element loses focus).
But what about the case where the value of a text box (for example)
is changed from a javascript function? Is an onclick event triggered
in such a case? I find that this is not happening in IE.
I have a big problem with a simple event : onchange!
If I write this page:
<html>
<body>
<form id="vu">
<input id="var01" name="var01" size="5" onchange="return false;"/>
</form>
</body>
</html>
everything is ok in IE (I can't leave the input zone !) but nothing happens in Firefox!
It looks like the event is not fired or...
Do you have any clue?
I have a button that opens a calendar and populates a text box. I use
the onclick event to open the calendar.
Now the textbox has a onChange event that calls a function. The
onChange fires perfectly if I type the date on the textbox, but if the
calendar changes the date on the field then the onChange event doesn't fire.
I even try the following, but it seems that both functions run at the
same time and the value on the field is never picked up.
I was working on a site that uses Google Checkout buy now buttons, and
I wanted the product picture to change based on what was picked. I was
able to have it change the picture, but if you pick a new item after
that, it keeps the same picture. Here;s the code:
The box (only the first part):
I've written some kind of menu to display a diagram with input fields
for a budget plan. A user should be able to change values, which are initially filled by
a database value, and get all corresponding values filled by the
program.
//value given by database
showText[k].setAttribute("value", eval("liste[i][TEXT" + k + "]"));
//onchange event for the user to change the value
showText[k].setAttribute("onchange", "calculate('cost" + i + "')");
//function to recalculate corresponding values
function calculate(myId) {
if (myId == "initial") {
...
}
else {
myId = myId.slice(4);
//getParents(myId) returns corresponding values for myId
var myParents = getParents(myId);
for (var i = deep; i >= 0; i--) {
var sum = 0;
for (var j = 0; j < myParents.length; j++) {
...
for (var k = 0; k < children.length; k++) {
sum +=
parseFloat(document.getElementById(eval("'cost" + children[k] +
"'")).getAttribute("value"));
}}}}}}
My Problem is:
IE and Netscape always use the value initially entered by the database
and not the new value entered by the user.
Is there a timing or DOM problem?
I have the following code running on my site...
Code:
<script type="text/javascript"> function test_func() { alert("You clicked the map."); } </script> <form action="#"> <input type="button" onclick="test_func();" value="Test"/> </form>
It works fine, but I want the form to call test_func onchange instead of onclick. I want to add an input type='text' named call_func that when changed, will call the test_func function.
I'm having problems. I am collecting data from an XML file and serving it up to a web page. Here's the code.
The thing is, I have taken a Submit button away and want the data to appear as the user types. I tried using onChange event handler but it only works when I click the mouse away from the input box, like an onBlur() event. Code:
I have 2 html menu.html and menu2.html, and would like to swich one another using "onChange" in each form. function pageCh works first time, but it doesn't 2nd time.

How can I change a select list when a user enters a value into a text box? Like with the below form I would like to have the select box change when the user enters a value in the "id" text box that matches a value in the select box. Say the user types "1122" in the text box I would like the select list to change to to show "John". Is this possible ....
View 5 Replies View Relateddoes anyone know of a way of forcing the onChange() event of a control (it happens to be a <SELECT> if that is relevant) to fire off? (That is apart from the obvious one of changing the value with the mouse / keyboard!!!!)
I have some code which alters the currently selected element in a list and I need the list's onChange to then be fired off. The code is designed to work with many different lists, so I can't hard-code the same functionality into my code that is normally provided by the onChange.
I've tried ....element.onChange() and .....element.Change() but neither of these seem to work.
<form> onchange event doesnt work in IE. but works in Mozilla. Is there any other alternative in IE for <form onchange>????
