JQuery :: How To Use The Change Function
May 2, 2011
I have an Autocomplete widget inside a function that works slightly differently depending on the country. It works. I want the user to be able to switch from country to country to country. I started with
getCityFromGeonames("#city2"); //select town via 2 steps - country, town
getCityFromGeonames("#city3"); //select town via 3 steps - country, stateProvince, town
This will select in the city2 input, then in the city3 input, then no further action is possible until you reload the page. So I put a change function around it.
$("#city2").change(function ()
{
getCityFromGeonames("#city2"); //select town via 2 steps - country, town
getCityFromGeonames("#city3"); //select town via 3 steps - country, stateProvince, town
).change();

I know in JavaScript you are able to write functions that you can just call at a later time. I'm working on a jQuery UI slider, and I wrote a function for the animation that happens when you start sliding. I would also like this same function to fire for the "change" event, but I can't seem to get it to work.
Here is the shortened code sample:
$(function(){
var posterO = $(".poster-slider")
.slider({
slide: function(event, ui){
//This is the function I would like to reuse at "change", below
poster.css(...);
posterLi.css( ... );
ptCopy.css( ... );
sliderValue = ui.value;
},
//change:,
animate:true
});
//When "#abundant-trees" link is clicked, the slider handle changes, firing the "change" event, but the "slide" function is not called.
$("#poster-switcher a[href=#abundant-trees]").click(function(link){
posterO.slider("value", 100);
link.preventDefault(); //Stop browser from following the link that was clicked on.
})});
I would like to apply the "slide" function to the "change" event without having to duplicate all the code.

I am trying to set up .focus and .change events on all of my form elements, but Javascript is telling me this.change is not a function:
$('#CreditCardCheckoutForm').find('input, select, textarea').each(function(index) {
this.focus(function() { resetExitSurveyTimer(); });
this.change(function() { resetExitSurveyTimer(); });

I have a select form with id=px. I want to make the select execute a function every time an option is selected. I took the Change function and my code looks like this:
$("#px").change(function () {
var str = "";
$("#px option:selected").each(function () {
str += $(this).text() + " ";
});
// $("div").text(str); - this line is changed with my function
$('#selectable1 span.cica').css('font-size', str + "px");
})
.change();
It looks that srt variable is not working with my .css function. What is wrong?
My markup is:
<select id="px">
<option class="option" value="8" label="8">8</option>
<option class="option" value="9" label="9">9</option>
<option class="option" value="10" label="10">10</option>
<option class="option" value="11" label="11">11</option>
<option class="option" value="12" label="12">12</option>
<option class="option" value="14" label="14">14</option>
<option class="option" value="18" label="18">18</option>
<option class="option" value="21" label="21">21</option>
<option class="option" value="24" label="24">24</option>
<option class="option" value="36" label="36">36</option>
<option class="option" value="48" label="48">48</option>
<option class="option" value="60" label="60">60</option>
<option class="option" value="72" label="72">72</option>
</select>

Having an issue with the .change functionality on a form selector in IE8 which I have not been able to figure out, and is now driving me insane.
When the select is change to an item with a value of 1, it is supposed to set the values of two textboxes to blank. Eg;[code]...
The most interesting thing is when I run this through jsfiddle to test it - it works perfectly there, but not when in our actual website (an intranet with a FQDN, and IE8 is set up to run such pages in standards mode, and not the default of compatibility mode).
Using latest version of jQuery (1.4.2-min), and no success. Same issues occurred when trying it in 1.2.6.

I have a form that is initially submitted by normal submit button, but after that I want it to resubmit on change(). I thought I'd be able to pick up the secondary change()s by adding a class to all of the inputs. However I now understand that won't work by default because the change() can't be attached to the class added by the the submit() as it didn't exist at the time, it was added by Jquery. I've since discovered on() but I'm now stuck on where to include it.
Here's the script so far:
The submit() adds the 'stu' class, and then the change() tries to select it but can't
<script>
$(document).ready( function(){
$("#search_choices").submit( function(evt){
runSearch();
$("input").addClass("stu");
evt.preventDefault();
});
});
$('.stu').change( function(){
runSearch();
});
function runSearch(){
var sFor
= $("#for").val(),
sWhere
= $('input[name=where]:radio:checked').val();
$("#search_results").load('search.php', { where: sWhere, treb: sFor } );
};
</script>

I don't really know how to say this, that's why I'm going to show you some code which will hopefully point out what I mean.This is what I wrote yesterday:
var div = $('<div></div>').attr('id','box').fadeIn(1250);
$('body').append(div);
This worked well, but then I wanted to make a function to be able to change the innerHTML of that div but it didn't work.
function changeContent(content) {
var box = $('#box');
box.html(content);
[code].....

My change function allows users to switch from country to country and get different text and features. It works when changing country selections. But at initial page load, it does not fire jQuery change to set the text for the default / initial country. When I change away and then back to the default/initial country, change fires and shows the proper information and features. I have tried document.ready with a change function both inside the switch selections and outside the change function. Neither work - they don't fire the hide, show and other jQuery in the switch cases at doc ready. Its not clear to me what function will fire the jQuery change function at doc ready. Here's the code. The country selection below is just 2 countries to keep it simple, but actually, there are many.
$

document
)

I have multiple inputs with names like "price1","price2" etc. and they added in the document dynamically after a user event.
I want to bind a function to them so everytime a change event occur to each one, i can calculate the new price. I try to use $("input[name*='price']").each(function(index){}); but I can't to this with live method and combine the change event too.

I wrote this function to be a change event applied to a checkbox. Now it is apparent I need to use it as a custom validator method, so it runs when you hit "Next" to step through the form. I have all that working, I just can't get the syntax of the rule right.
Here it is as a change event:
$(
'#MKDPT'
).change(
function(){
if(
$(
'#MKDPT'
).is(
':checked'
)){
var
checked
=
false
; .....
And my attempt at a custom validation rule:
$
.
validator
.
addMethod (
"MKDPTOnly" ,
function (
value .....
I have tried several versions, but none is letting the form go to the next step (return true) if the conditions are met.

I'm attempting to make a simple hover image gallery with a static large image which swaps with a thumb on hover. However, on hover what happens is the new image comes up as the large image and if I then hover over another thumb it replaces that thumb with the original bigpic image source.

I have a button that change a number of images src's when I click a
button. The src's are stored in an array and I just use
document[imgName1].src=pics[0] to change the src of the image.
However I want the button to change the link as well to the image that
is displayed but i cannot get it to work. How do I do this. Could
someone tell me or point me in the direction of some code that will do
this.
I would like to do it in a similar way to the pictures. i.e. have all
the links stored in an array and change them when the button is
pressed.

I got 3 sections on the site, at the bottom of each are 5 bars which are used to change the text color. I'm trying to minimize the code, so I created an array which contains all the colors, but I'm not sure where to put the call to the array. If I put it in the for loop, the selected color will always be green no matter which color you click. The bars should also go up to 40px when clicked and when the next bar is clicked the current bar at 40px should go back to it's originals size(20px)
this is the JS
var colors = new Array(4);
colors[0] = "#ed1c24";
colors[1] = "#736257";
colors[2] = "#620460";
colors[3] = "#e87e01";
colors[4] = "#00a650";

I am using one select to update another and everything works perfectly. However, I am finding the "change" function fires when I use "replaceOptions" to update the second select even though I'm simply re-initiating the second select with a new set of options. I think the "change" function should only fire when I do I physically select another option in the second select and not every time I update the first select. I've recreated a cut/paste demo to illustrate the point below. As you can see, the alert occurs when changing either the first or second select.
<?xml version="1.0" encoding="UTF-8"?>

I have an image with an onclick function and parameters 0, 1. I want to change the parameters of the onclick function through the same function?
<img id="down0" onclick=swap(0,1) />
<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}
</javascript>
Normally it should change the onclick to swap(1, 2) but it remains 0, 1.
