'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'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?
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?
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?
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!!!
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?
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?
I have a drop down list in html which contains 3 items; Black, white,blue..If i select "Black", a pop up window should come up. (Alert or confirm)JS and need to complete My academic project work.
I am trying to add an onchange event to a select tag.
This is my code, but it does not appear to be working.

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 want to make one application using javacript or may be it is in ajax. Let me explain my problem: I have one select box name person which have value 0,1,2,3,4,5 . Now i want that when user will select value 1 from select box then person 1 first name , last name input type box will appear only one time in a row. and if we will select 2 from select box then two row will appear naming person1 and person2 like this: if we will not select any value by default is 0.then it will not show any row regarding person.
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?
