I need to execute a jquery function on change of options in ddslick dropdown...
$("select[name=ddslick_select]").change(function(){
alert("changed");
});
I am using the name of the select to get the value changed event. So that on change of the value of that name will be recognised. But, I couldn't execute the function.
Note that ddslick also provides its own callbacks:
$('input[name=ddslick_select]').ddslick({
// other options...
onSelected: function(data){
alert("changed");
}
});
The select changes, the option does not -
$('.classOfTheSelectElement').on('change', function(){
alert($(this).val());
});
see if this alerts your selected options value
User select instead of input for dropdown:
$("select[name='ddslick_select']").change(function(){
alert("changed");
});
or simply use name attribute:
$("[name='ddslick_select']").change(function(){
alert("changed");
});
ddSlick implements a Callback for that
$("#myDiv").ddslick({
data: ddData,
defaultSelectedIndex: 3,
onSelected: function (data) {
alert("change");
}
});
This solution
$("select.ddslick").each(function() {
$(this).ddslick({
onSelected: function(data){
console.log(data.selectedData.value);
}
});
});

I am trying to get change value of input when its values are changed.
http://jsfiddle.net/stackmanoz/694W9/
$(function () {
$('.color-iris').iris();
$('#color').on('change', function () {
console.log($(this).val());
});
});
I am using color-picker and after the input's value has changed with the new color value, I want to get its value.
But this is not going well.
Please guide me through this
Use option change
$(function () {
$('.color-iris').iris({
change: function () {
console.log(this.value);
}
});
});
DEMO
Change event would be fired only when that textbox value changes as wel as focus is getting blurred out from the particular text box,so in this context you have to use input
$(function () {
$('.color-iris').iris();
$('#color').on('input', function () {
console.log($(this).val());
}) ;
});

I'm trying to change the value of two dropdown lists when a third one changes, to that dropdown's new value:
<script>
$('select[name="d1"]').change(function() {
$('select[name="d2"]').val(this.value);
$('select[name="d3"]').val(this.value);
});
</script>
Nothing happens.
Try this for starters, work your way when you get this to work :)
$(document).ready(function() {
$('select[name="d1"]').change(function() {
$('select[name="d2"]').val(this.value);
$('select[name="d3"]').val(this.value);
});
});
Try like this
$(function() {
$('select[name="d1"]').change(function() {
$('select[name="d2"]').val($(this).val());
$('select[name="d2"]').html($(this).val());
});
});
I have a jQgrid with a multiselect option set to true. When the multiselect checkbox is checked, I don't want to highlight the rows in the grid.
The checkbox has an id of "#cb_emplist "
I tried the following, it works in chrome consol but not in the code
$("#cb_emplist").change(function() {
$('#empList tr').removeClass("ui-state-highlight");
});
I also tried :
$("#cb_emplist").change(function () {
if ($("#cb_emplist").is(":checked")) {
$('#empList list tr').removeClass("ui-state-highlight");
}
});
jQuery("#empList").jqGrid({
.....
...
multiselect: true
...
});
Solved with this puppy here:
$("#cb_emplist").on("click", function() {
$('#empList tr').removeClass("ui-state-highlight");
});
For the code which is dynamic you may need to delegate the events like below
$(document).delegate("#cb_busgrplist", "change", function({
$('#empList tr').removeClass("ui-state-highlight");
});
Read the Delegate documentation here
This seems to have done the trick:
$("#cb_emplist").on("click", function() {
$('#empList tr').removeClass("ui-state-highlight");
});
I have two elements as following on my page:
<input type="text" id="textfield"/>
<input type="button" id="button" value="CLICK"/>
And in my Javascript code I have the following:
$(document).ready(function() {
$("#button,#textfield").on("click change",function() {
// This won't work because I don't need click function
// to be worked on the text field
});
});
What I need is click function to be worked on button and need only change function to be worked on text field. How do I do this?
If you want the same code to be called for different events on different objects, you can put the event handling code into a common function and then specify the exact conditions in each event registration:
$(document).ready(function(){
function myEventHandler(e) {
// your code here
}
$("#button").on("click", myEventHandler);
$("#textfield").on("change", myEventHandler);
});
Split your code into:
$(document).ready(function(){
$("#button").on("click",function(){
});
$("#textfield").on("change",function(){
});
});
Why did you put them together?
Seperate to two function:
$("#button").on("click change",function(){
// Handle button
});
$("#textfield").on("change",function(){
// Handle Textfield
});
Assign them separately:
$('#button').click(function(){
//button code here
});
$('#textfield').change(function(){
// text field code here
});
If you want them to do the same thing, create a separate function:
function doSomething() {
// text field and button code here
}
and then reference that function instead:
.click(doSomething);
...
.change(doSomething);
Also, i should tell you, "change" does not do what you would think for a text field. It does not fire while typing, only when you "blur" the text field after updating it. It's more for checkboxes and things of that nature. I would use .keyup()
Try:
$(document).ready(function(){
$("#textfield").on("change",function(e){
my_function(e);
});
$("#button").on("click",function(e){
my_function(e);
});
function my_function(e){
// e = event...
// your actions...
}
});
Try using like this if you want only one .on function
$("#button,#textfield").on("click change",function(){
if ($(this).attr('type') == "text"){
alert("Do your change function");
}
else if ($(this).attr('type') == "button"){
alert("Do your click function");
}
});
See Demo
$('input').change(function(){
alert($(this).val());
});
$('input').val(1);
This dont work. I need capture the change input with JavaScript :-s
Thanks.
Programmatic changes to <input> elements don't cause events. Only user interaction does.
You can do this however:
$('input').val(1).trigger('change');
You have to put those functions inside the "Ready" function. see the fiddle: http://jsfiddle.net/SfjJQ/1/
$(function() {
$('input').change(function() {
alert($(this).val());
});
$('input').val(1);
$('input').trigger('change');
});
keep in mind that your:
$('input').val(1);
initializes the input to have a value of 1.
Of course you could also do this:
$(function() {
$('input')
.change(function() {
alert($(this).val());
})
.val(1)
.trigger('change');
});
As others have mentioned, .val() does not trigger any events; however, you could add a wrapper function to jQuery that will change the value and trigger the event if wanted:
$( function () {
//-- new jQuery function
$.fn.changeVal = function () {
$.fn.val.apply( this, arguments );
$( this ).trigger( 'change' );
};
//-- your updated code
$('input').change(function(){
alert($(this).val());
});
$('input').changeVal(1);
} );
