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.
I have a button and when I click on the button I want to reload my DatePicker accordingly and launch the beforeShowDay event of the datePicker from my click event. How can I do that? How to set the DatePicker date to the ListDate[0] date?
I've spent a good while trying to solve this on my own with no luck. The .blur jquery event I'm trying to use isn't firing and I can't figure out why.My entire JS file:
I want to handle focus and blur events on any DIV element but don't know how? I tried this one: $('.myDIV').bind('focus',function(event){ // something }); But it doesn't work!
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?
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;
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().

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 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"); }
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.
i want to store current textbox value in session on onblur event of textbox. how can i do this. i am using javascript ans asp.net 1.1. And How can i call server side function on onblur event of textbox.
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:
'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".
I want to use an onkeydown() on my web site and the web site to know which key I pressed. Specifically know I pressed the arrow keys and store which key was pressed in a variable.
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.
I have a table that contains a select element like so
<tr><td>key value in hidden input</td><td><select>options</select></ td></tr> I need to set $("selectclass").change(function() { //Find the value of hidden input in 1st cell of row of the select list that was changed. });
So when a user changes the option of the select i need to get the new value the option has been changed to plus the value from the hidden input and submit them via ajax to a method on the server. How can i get the hidden inputs value?
The problem is...when I type in search textfield it focus in the name list..like for example i type a after I press a it was focus in the firstname, which is wrong..I think it cause from the javascript code..I want to happen is i continue typing in search textfield.
I have a text field on my page, whose value I am setting through the jQuery cal
$('#Expandable').val("fefefe");
However, when I normally type into the text field, certain events occur as the text field value changes. These events do not occur when I set the value like above. So my question is, after I set the value, how do I invoke any onChange handlers?
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.
