JQuery :: OnChange Event - Web Application - Each Blur Event Makes A Call Webserver To Store Value Of Textfield

Jan 21, 2010

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:

JQuery :: Executing Code On Blur Event?

Dec 2, 2010

I am doing a simple function to validate text fields(you can see the code below). Now, the alert box appears only once when I refresh the page, not when I click inside or outside the username box. #username is the id of a input text field. On a sidenote, how can I pass multiple parameters to the function(not a fixed number of params)? or should I just pass an array?

JQuery :: Validating Textbox Entries Using The .blur Event?

Jul 15, 2011

I am sure that this is a BASIC question for javascript gurus but I'm struggling to resolve.The form starts with the cursor focus in the FROM ACCT NUMBER FIELD. When I tab to the next field without entering any value in this text field I want to send an alert to the user that the field is required and put the cursor back on that field. I attempted to do that using:

$(function() {
$("#ARTransferForm\:fromAccountNumber").blur(function() {
var fromAcctNumLen = $("#ARTransferForm\:fromAccountNumber").val().length;

[code]....

JQuery :: Click Event Not Fired When Hide() Called By Blur()

May 24, 2009

I have a textarea and a DIV as code below. The way it supposes to work is when I focus on the textarea by clicking it, the DIV will show. Otherwise, it will be hidden. Then when I click the DIV, there will be an alert(). However, right now if I click on the DIV, it will trigger the blur() event first which calls to hide() the DIV. After that, the click event is not called at all. I need to be able to click on the DIV and the DIV is not hide() at all and show alert().

Popup Window Blur Event

Jul 23, 2005

I'm triing to write script that close popup window, when user click outside the popup. Script below is working fine in firefox (v1.0.3), but not in IE.

I tried also to print hello but still the same problem firefox OK IE not. I think the problem is in event capture, but I can't fix it.

My script:
fotowin = window.open("", "foto", "width =100,height
=100,location=no,menubar=no,directories=no,toolbar =no,scrollbars=no,resizable=no,status=no");

fotowin.onblur = closeWin;
if (fotowin.captureEvents) {
fotowin.captureEvents(Event.BLUR);
}

function closeWin() {
fotowin.close();
//fotowin.document.write("hello");
}

Detect The Source Of A Blur Event?

Feb 10, 2010

I have these "editable" divs in my document. When you click them, a text box comes up and you type something and push enter. It changes what's in the div.There is also a blur event associated with the text box. When the user tabs or clicks away, it fires the blur event. Here lies the problem.I have other elements on the page that are clickable. I don't want those clickable things to fire their events if the user is clicking away from the text box, ie. the blur event. This isn't a problem is the user pushes tab, for instance.

JQuery :: Making Call On BeforeSend Event Of Another Call?

Apr 30, 2010

I need to make a $.post call on the beforeSend event of another $.ajax call.I read the documentation and I see that if the beforeSend return false the ajax call will be interrupt.So I made this code but doesn't work, because the real value of the beforesend function isn't true or false, is the value of the post.I have to do this because when you click on a link I need to verify before if you are able to do this via db permission of my webapp.I think you don't understand...This is the code:

$.ajax({
async: true,
beforeSend: function(){[code]....

});I see always the alert of success event, so the return of the beforesend is not correctly done.

Ok, so the above code will do the regex when the contents of the textbox changes, but it does not seem to call the checkPrice function I've placed after it does the regex.

I have the above on Change code in a .keyup event and it works as expected.

OnChange Event Is Not Working

Jul 23, 2005

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...?

Cancel OnChange Event

Jul 23, 2005

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.
