Onchange And Onkeyup Does Not Work On IE?
Mar 4, 2011
I have client side scripting for a text box value which truncates value if user enters more than 255 characters. For this i use both onchange and onkeyUp events. I added Server side validation too(more cautious) to restrict user from continuing the page if he enters more than 255 chars. We are using this product from 7 yeras and yesterday one of the customer said that(he has a screenshot too) he saw the server side error message. this explains that my client side javascript methods doesnot fire. he is using IE browser.

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've developed a support page where users can drop in help tickets with javascript doing client side testing of the fields for missing data etc and php for server side handling and posting to an email address. There is also a section to add supporting images, videos etc of the bug/issue using the <input type="file" /> tag.
Although I could have done server side file size checking, I didn't want my users to wait half an hour to up load a 10Mb video just to be told it was too large to send via email.
So my client side solution was to have a function fire when a file is selected:
Code:
<input type="file" id="attachment1" name="attachment[]" onchange="findSize(1)" />
The id is name 1 because I have javascript to allow the user to add multiple "Select a file" boxes, dynamically adding 1 to the id number each time. The name is an array for the server side handler of the multiple files (if any). The onchange you see fires "findSize(attachmentRef)".
Code:
function findSize(id) {
var maxFileSize = 5242880; //5mb in bytes
var idNumber = id;
var fileInput = $("#attachment"+idNumber)[0];
[Code]....
This is the findSize function that feeds back to the user instantly if the file is too big for processing - saving headaches all round. I use some jQuery to work out which file input we are looking at and to test the size of the file. If the file is too big, an alert flag is written into the form to prevent the user from hitting submit (one of my client side test conditions for checking the form confirms that this flag is 1 not 0).
Issue: The code works fine on my test browser - Chrome. But in my next step test (FF 7.0.1 and IE9) nothing happens. I can locate and add a file for upload, but the onchange doesn't fire. Or is it something in my function that is causing the bug? I'm using jQuery 1.4.4 for your info.
how to implement onchange with different browsers - something about IE and FF differing in what they mean by a change and when it happens; but I admit I'm a bit lost. Can any one spell out a solution ABC fashion?

Wrote what I though would be a simple script to convert Fahrenheit to Celsius, feet to meters... and vice versa. It uses onchange="calculate(this)" in the input fields, so when the individual enters a number and hits tab or enter it automatically calls the calculate() function and does the needed conversion. I'm passing (this), 'this' being the input field, and calculate() pulls out the needed data for the conversion.
It works great in Firefox. But in IE or Opera, the calculate() function never even gets called. I've searched for an answer, but to now avail. I haven't written much JavaScript and am not entirely sure what's causing the problem. Kinda makes me think of Java, where if you want to use action listeners, you need to first instantiate a listener object. Is there somekinda event listener in JavaScript that Opera and IE want instantiated? Here is my code in it's entirety.

I am trying to make one application. When we slect value from select box . It will show same type of row according to which value we select from select box.
Let me explain my problem: select box have value 0,1,2,3 . When we select 1 then it will show one row below the select box naming person1 name (input box for name of person1). if we will select value 2 from select box then it will show two row according to select value Like this
person1 Enter Name of person1
person2 Enter Name of person2
By default it have value 0 then it will not show any row below the select box.
i want to do this. But i do not know how i can do this . I think for this i have to onchange event in select box .But in correct way i do not know how it is possible.

I am trying to include two functions in an onchange when the user selects a new value from a select list: It is a quite big form form - There are one select list, when changed - TWO other fields in the form needs to change accordingly: I put the information back using ajax and place it within a <span id="blah"></span>; I have checked the span ids, and they are correct! Unfortunately, the second function disables the first one This is the select list with the onchange functions:

I have 2 dropdown lists which are connected to a mysql database. When I select an item from the first dropdown list the second dropdown list should show item which are linked to the item from the first list. But the thing is I can select an item from the first one, but the second isn't showing anything.
In the mysql database I have 2 tables: hesk_programma and hesk_projecten. In table hesk_programma there are a ProgrammaID and Programma column. In table hesk_projecten there are a ProgrammaID, a ProjectNumber and a Project column.
ProgrammaID from the two tables are connected to each other, so when I select an item from the first dropdown list with the ProgrammaID AK, the second dropdownlist should only display the items with the ProgammaID AK from the hesk_projecten.
Here is the code I use:
PHP Code:
<?phpÂ
mysql_connect("localhost", "root", "");
mysql_select_db("bestellingen");
$query = "SELECT * FROM hesk_programma ";
[Code]....
By the way, one more thing. The ProjectNumber from the hesk_projecten table should be displayed (when selecting an item in the second dropdownlist) in a input text field.

I've got this listbox full of hundreds of employee names. Clicking on a name executes a function using onchange. Because of the length of the list I decided a search function would be really handy and I finally found one that works.
Now the search function, when you type in the input box, scrolls the list to the first matching entry. And that's good, that's what I wanted.
The problem comes in when you try to click on the name the search function found. Nothing happens ofcourse because the onchange tag in the list reacts to changes, not direct clicks.
code:
The list is populated by java but for testing I disabled the function that clears the "Loading" option and I set it to selected. That way the loading option is highlighted by default and the search function is free to highlight something else, then when I click on the search result it works like it's supposed to.
But keeping a highlighted option at the top of the list for that sole purpose isn't very elegant, especially since if you click on it the onchange function tries to execute and generates errors. The only solution I can think of is to use java to generate another option way at the bottom of the list that has the selected attribute but I don't quite know how to do that.

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.

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.

Why this code doesnot work in IE (I test in htmlKit).
Code:
I have problems with this event in more testing examples.
This I found about this problem, but it does not help to solve this thread
Bug problems:<br/>
1. language attribute should not be included. Instead, use type="text/javascript"<br/>
2. onkeyup should be all lower case. <br/>

I'm having trouble trying to check if a key is down, using javascript.The code below is only a simple test script, and should just write "!" while the left arrow key is down.It seems to be able to detect when the key is pressed, but it doesn't stop when the key is released (on Opera at least - unsure about others).btw: I'm not interested in making it work with IE, as I'll be using other stuff which IE doesn't support anyway (Canvas/SVG).
Code:
<script type="text/javascript">
// keyLeft should be True if Left Arrow Key is down
var keyLeft;

I have an ajax search function. I have an input text field where I type in what I want to search for, but I would like the search to be delayed of a few miliseconds before the ajax search is called. How could I do that?
The search field:
The javascript function:
Here is my ajax search...
I tried different ways but I don't seem to be able to delay the searchPlayer function. Any help on that?
Should I use setTimeout on the input field, or in my function or in another function? And how do I pass the 'this.value' to my searchPlayer function if using setTimeout?

I have a function that checks to see the number entered in a textfield and then, if greater than 1, will change a radio button from Single to Multiple and visa versa. The function is called from the textfield with an onkeyup="function()". The problem I am having is that it works in IE just fine, but in Firefox it doesn't seem to be doing anything. I'm not getting any errors and can't seem to see what is the problem.

I have an AJAX script and the input field uses:
<input name="domainname" type="text" class="domainform" onkeyup="javascript:get(this.parentNode);">
to display the search results as the user is typing.
I pretty much know there is a way to do this, but how would I go about making it so that instead of activating the script as soon as a key is typed (onkeyup), it would wait 1/2 second or maybe 1 second before actually going forward with javascript:get(this.parentNode);
This would reduce server stress so that its not taxing the server every time the user hits a key to type something.

Im using onKeyUp on a text input field and everytime some information is gathered from a database through ajax.
Is there anyway to cancel onKeyUp events that are within X seconds of the previous event trigger? I dont want to use setTimeout because i dont want them called at all.
