View 3 RepliesI would like to use some event handling on a form, not something I have done before and looking for some assistance. Here is my code:
<select name="LocO">
<option value=""></option>
<option value="O">Outside</option>
[code]....
So what I need to happen, is based on the selection of the first selection box, some of the options of the other selection boxes should not be available.If Outside is selected, everything in LocA should be available, but only up to 4 in Loc1... and if Inside is selected, only up to E should be available in LocA and everything should be available in Loc1.
I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:
Is there anyway to trigger an onChange event without actually clicking etc.
I want to trigger it from a method. It sounds silly but I'm taking some code over from another developer and if I could do this it would save me days of re-writing!!!
I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :
label.onfocus {
color:red;
}
but a little confused on what else.

View 2 Replies View RelatedI'm handling a form submission event. Is there a way to modifiy the value of a text input within the form before the form is finally submitted? I tried setting the value using, 'val()' - it updated the text field but the value sent with the POST was the original value
View 4 Replies View RelatedI have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.

My question is: How could i use the event onchange to make a function which
update the data of array when i would have change data in a text box.?
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 text box in a jsp that is pre populated. The text box should accept only numbers and it should be greater than a minimum value (this value depends on the user settings). If the user enters a value less than the minimum value, i should pop up an alert saying that the value
entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.
Am I right in assuming that you can NOT set focus() back to a field in
its onChange event? Is there another way - I have validation that I
would like to set the focus back to the invalid field onChange?
Eg:
<input type=text" name="tstfld" onChange="window.alert('Changed!');
this.focus()">
I'm trying to get a tick box to tick automatically when the user changes the
textfield called comm. my code is below but it doesnt work.
Can anyone see why?
function changed(x)
{
document.getElementById(x).checked;
}
<input name="changed" id="ischanged" type="checkbox" value="">
<textarea name="comm[]" rows="2" class="BodyText" style="WIDTH: 99%"
onChange="changed(ischanged)"><?php echo stripslashes($comment);
?>
</textarea>

I'm having some difficulty in accessing an 'external' function from my onchange event. It will work when the function is included 'inline,' but it's not working when the function is 'stand alone.'Additionally, when it works, the variable isn't being passed - the alert I use says "[object Event]"
Code:

function nameTextBox2(selectBoxName)

I'm using selectedIndex to change an option in a listbox, but I'm finding that the onChange event doesn't fire unless I manually make a selection. Is there any way to effect the change by JS so that the event works?

I have two frames. Frame "search" contains a search form specifying
an onsubmit action like so:
<form ...
...
</form>
The other frame contains a <img ... where
the perform_search function is defined as follows:
<script language="JavaScript">
function perform_search() {
var frame = parent.frames.search;
var form = frame.document.forms.mainForm;
form.submit();
}
</script>
Now, when hitting Return in the search form, then foo() is called
fine. But when clicking on the <img ...
in the other frame, foo() is NOT called.
Is expclicitly calling foo() from perform_search() the only way to do
it, or is there a magic incantation that might do what I want?
'm trying to use jQuery to append to the onchange event of each of the following input elements. The following code actually replaces the event. When the onchange event fires on any of the elements, I get one alert which just says "new". What I would like to see is 2 alerts, one that says "test?" where ? is the element that changed and another that says "new".
