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 :: 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.

JQuery :: Datepicker OnSelect Event?

Jul 18, 2009

I'm trying to make use of jQuery's datepicker. The hidden field is used to make the datepicker appear and stores the date data that will be sent to the server. The SPAN tag will show the "pretty" date format for the user.

The altField option doesn't seem to work, as the SPAN tag is not an INPUT tag. So, I saw that I could add a custom function using the onSelect event, so I attempted to write what you see below. I can't seem to find any clear documentation on how to handle the "inst" variable or how to pull the date from it so it can be formatted.

If I use the "dateText" variable, that only seems to contain the date as a formatted string, and not as a Date() object that I can format.

JQuery :: Datepicker: Fire An Event When A Date Is Selected?

May 27, 2010

I have a jquery datepicker that is working fine. I'm using a calendar icon only to start the datepicker and the result (the chosen date)is shown as text - not as an input field. To get this result to show, the user has to click an 'update' functionbuttonfirst, which in my case has nothing to do with the datepicker itself. I know I can use altField to show the result immediately, but that has drawbacks. SoI would like to improve the way it works as follows: when the user picks a date, I want the datepicker to close (which it already does) and the chosen date to show immediately, without the user having to click the 'update' button first. How do I do that? I don't like to use altField, as the user can muck around with the result if they want to -it is an input field after all.

JQuery :: Displaying A Datepicker On Custom Button Click Event

Jul 21, 2010

I wanted to show a datepicker on a custom click event. i can't use datepicker button or image due to lack of space and certain other restrictions.

I have created a custom button with a custom look and feel. i want the click event on this button to trigger datepicker display.

I tried to use:

But this is merely associating the textfield datepick with datepicker, its not showing it.. rather we have to click on textfield after the button click to show the datepicker.

I also tried:

But this also did not do any changes..

Any possible way for getting this event..

Using Onchange To Call PHP Include And Set Php Variable?

May 14, 2010

I'm building a form in PHP. One of the fields needs to generate information based on another selected input. The first input is for "phase" and based on that I need to count how many entries there are in the database for that phase, then display posible positions(ie 1 per entry including the entry being edited/added). I know that this can't be done with only PHP.

I don't work with Javascript normally so I am struggling. I have read many similar topics, but can't find the answer I am looking for.

I thought that the solution could be to call an include file when a selection for phase is made, but I don't know how to pass the information to the PHP script.

I'd prefer not to have to reload the page or form.

Here's the code that I have so far:

Code:

<html>
<head>
<body>
<form action="edit-category.php?id=<?php echo $id; ?>" method="post"

[Code]....

JQuery :: Function Inside Onchange Event Not Firing?

Jul 12, 2010

$('#newPrice').change(function() {
this.value = this.value.replace(/[^0-9.]/g,'');
checkPrice();

[Code].....

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.

JQuery :: Changing Text Field And Invoking The Onchange Event?

Mar 16, 2010

I have a text field on my page, whose value I am setting through the jQuery cal

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?

Onchange Doesn't Trigger Function Call?

Jul 14, 2010

THIS WORKS:

<html><head><script type="text/javascript">
function recalc() {
alert ('Entering recalc().');
}

[Code]....

The first example works, which shows that the recalc function can be called. The second example works, which shows that onchange will trigger an alert box. BUT, the third example doesn't work. Why can't I trigger a call to the recalc function from the onchange event?

The above 3 code postings are the entire programs. Nothing has been left out or modified.

I am using IE 8.0.6001.18702.

JQuery :: Populating Dynamically Created Input Element Values Using Datepicker And .live Event Handler

Nov 15, 2010

I have a table with a date field in each row:

The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:

The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?

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.

OnChange Event And Focus()

Jul 23, 2005

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()">
