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 know this must be pretty basic but I can't get it to work. I've written validation for a text field- it should have no periods in it. I want to reset the value of the field then give the field focus, if it has a period. Here is my code:
Quote:
function checkTitle(field) {
var titleFilter=/./;
if (field.value.match(titleFilter)) {
alert("Please enter your title without periods.");
field.value=''
field.focus();
return false;
}
else {
alert("good");
}
}
I call it from onChange. It resets the value but the focus goes to the next field (or stays there I guess.) Is there a way to set the focus on the same field?
PS I should mention, this form has disabled the "Enter" key and I can't change that behavior. I've been tbbing between fields, and it is when I tab that I am experiencing the problem.
My script is designed to show a simple question and the user submits the answer using onchange via the tab key. If the answer is correct the next question appears and so on. But if it's wrong there's an alert and the user stays at that question and has another go to enter a correct answer to move on. It works well as long as user gets answer right. If they enter a wrong answer I'd like that answer box to clear and be focussed (ie cursor in place). Problem is, using the tab key has already sent the cursor off to highlight the address bar! I can get it to work if each answer box has a submit button and I use onclick but I really want to change the submit function to a keystroke, pref TAB.

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:

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 have an array with mysql´s data. I have used this array with several text
box in a formulary.
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.
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?

document.getElementById(x).checked;

<textarea name="comm[]" rows="2" class="BodyText" style="WIDTH: 99%"
onChange="changed(ischanged)"><?php echo stripslashes($comment);
?>

I 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 would like to have a dropdown to only show when a certain value is chosen from another drop down.
So if in this dropdown the value ETS Rep Discount is chosen he should show the other dropdown
<div class="row">
<div class="fieldName">Discount Type</div>
<div class="fieldValue">
<asp:DropDownList ID="discountTypeDropDownList" runat="server" AutoPostBack="True"
Width="295px"

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]"

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?

View 3 Replies View RelatedI 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!
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've got to write some javascript to listen for a select 'change' event. Unfortunately, the select box has an onchange event as well. For example:
<select name="test" onchange="document.form.submit();">
Here's my event listener:
function handle_submit() {
return false;}
function addListeners() {
if (document.addEventListener) { document.form.test.addEventListener('change',handle_submit,false);
}}
window.onload = addListeners;
Now, the event listener does capture the event, but I want to cancel the onchange event within the select box. Is that possible?
