JQuery :: Select Onchange Event Get A Value From Selects Table Row
Oct 23, 2009
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?

Here is the html:
<select name="activities_limit" id="activities_limit">
<option value="5" selected="selected">5</option>
<option value="7">7</option>
<option value="10">10</option>
<option value="14">14</option>
</select>
And the jQuery:
$("#activities_limit").bind("change", function() { alert("value changed"); });
I am not seeing the JavaScript alert though.

2. If I submit the form using the Submit button, it works except I get:

I have a select dropdown which has two events an onchange and onkeypress.
My problem now is when I use the keyboard arrows to select an item from the list in a select drop down the onchange is selected(invoked) before I even reach the second item in the list when using opera and IE but working fine with Firefox and chrome.The onblur event does not work either because the focus must be set to following tag

For some reason my change() function is only called when the page loads. I'd
much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() {
var new_select = new Selector('tdata','myselect','myid');
var new_select_list = new DataSource("some_list");
new_select_list.addItem(1,"One");
new_select_list.addItem(2,"Two");
new_select_list.addItem(3,"Three");
new_select_list.addItem(4,"Four");
new_select_list.addItem(5,"Five");
new_select.setDataSource(new_select_list);
new_select.formInput("form","input");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
<td>
Select:
</td>
<td id=tdata>
</td>
</tr>
</table>
</form>
</body>
</html>

In a <select> drop-down, the onchange event isn't called when
scrolling through the dropdown using the mouse-wheel and when crossing
over a new <optgroup>.
Using the example below, notice how the onchange event isn't called
when mouse wheel scrolling between A3 and B1, but it works properly
when scrolling between A1 and A2.
E.g.
------------------------------------------
<html>
<body onload="document.forms['myForm'].elements['mySelect'].focus()">
<form name="myForm" id="myForm">
<select onchange="alert('onchange event');" name="mySelect"
id="mySelect">
<optgroup label="Group A">
<option value="A1">A1</option>
<option value="A2">A2</option>
<option value="A3">A3</option>
</optgroup>
<optgroup label="Group B">
<option value="B1">B1</option>
<option value="B2">B2</option>
<option value="B3">B3</option>
</optgroup>
<optgroup label="Group C">
<option value="C1">C1</option>
<option value="C2">C2</option>
<option value="C3">C3</option>
</optgroup>
</select>
</form>
</body>
</html>

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:

var lstFrom = $(from);
var lstTo = $(to);

Is it possible with AJAX chained selects to have one select box on the page and then have another select box appear depending on the selection from the first select box?[URL]Is it possible to hide the 2nd box until the first one was acted upon?
My goal is to start with one box (call it Box 1). Box 2 will then appear. Depending on Box 2's input, Box 3 will appear with new choices. Depending on Box 3's input, Box 4 will appear....so on and so forth until the end goal is met.
When additional boxes appear, I do not want the previous boxes to disappear. If PHP can populate the select boxes, I don't see why it also couldn't insert the physical select box.

I searched here and some other places on the net but cant find anything that suits my needs. I have a SELECT box with 3 values Code:
<form name="form1">
<select name="length">
<option name="length" value="none">--Select for All--</option>
<option name="length" value="5">--5 Days--</option>
<option name="length" value="7">--7 Days--</option>
<option name="length" value="10">--10 Days--</option>
</select>
</form>
OnChange, I want to invoke a function that auto populates the rest of the SELECT fields in the form. The select boxes will vary in quantity as the page is dynamic, but the values are always the same (like the code above).
Does this make sense?

'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 have a button which creates a clone of the current row. Within each row is a drop down box for which the users can select red or yellow, which represent soccer cards. Based on that selection it calls a function which populates a div tag with the appropriate drop down options for that card color. The problem I am having is that the function is updating all div tags with the drop down selections and not the one for my current row. Please note that the drop down selection box is not guaranteed to be the last row in the table. The referee could go back and realize, that he or she made a mistake and make a change to the second row. So I need this to always be applicable to the current row of editing.

$('#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.

I'm quite new to jQuery but love learning new tricks. I have a search box with a labelOver applied for the hint text and a select dropdown with 4 options. I would like to change the hint text depending on which option is selected.
Eg if the user selects "People" the hint text will read "eg. John Smith", if they pick "Year" the hint text will read "1985".

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?
