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.
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 am trying to add an onchange event to a select tag.
This is my code, but it does not appear to be working.

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 am trying to make one application. When we slect value from select box . It will show same type of row according to which value we select from select box.
Let me explain my problem: select box have value 0,1,2,3 . When we select 1 then it will show one row below the select box naming person1 name (input box for name of person1). if we will select value 2 from select box then it will show two row according to select value Like this
person1 Enter Name of person1
person2 Enter Name of person2
By default it have value 0 then it will not show any row below the select box.
i want to do this. But i do not know how i can do this . I think for this i have to onchange event in select box .But in correct way i do not know how it is possible.
I am trying to extract the value from a selected item in a Select/Option, parse it server side using asp and then populate a text box on the same page with the value that was parsed. simple example below:
Two problems I have here:
1. The code: this.frmEditUser.Submit; does not appear to submit the form.
2. If I submit the form using the Submit button, it works except I get:
Currently I am using an onchange event on a select menu and it is working fine. But if the user uses any arrow keys the event will not trigger. Is there any way to do that?
View 4 Replies View RelatedI 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>

I have a question that's probably basic javascript, but I can't find the answer.So if any of you can point me in the right direction?This is the problem:I want to loop through an array and in each iteration I want to bind a value from that array to a click event.I made a small example where I only bind the first iteration to a click event.
$(document).ready(function(){
var dummy=new Array();
dummy[0]=1;

New to javascript/jquery and have a question regarding scope. I want to bind an event within my class so it calls one of the class methods. The problem I run into is that the event handler is a anonymous function that runs outside the scope of the class, therefore it doesn't see the class methods or properties.
Is there a proper way to deal with this:
Sample code:
function myObject(tag) {
// properties
this.myvar = 'test';
this.tag = tag;
// methods
function sendRequest() {
alert(this.myvar);
}
// initialization
$(this.tag).click( function() {
this.sendRequest();
});}
I have developed a plugin for mutual selection on a list of elements.It works fine if I make those element into mutual list only once.
like $("appropriateSelector").toMutualSelect();
that plugin will add click event handler to each element and they remember the whole list by enclosure.
If I add new elements to that list. and do$("appropriateSelector").toMutualSelect(); again. New elements will behave as expected but old ones will have problems. Each old element will have the same handler bind multiple times to them. That will result like toggle two times andmessingup the outcome. How do I prevent this? I am trying to clean up their bound handlers but seems no luck.
I am not sure - I made ajax call through jquery form plugin, return response is HTML fragments, and inserted to a <div> place holder, work as expected.However, previous HTML segments have binding events (such as click) seems lost after the insertion ... is this expected behavior? and what are the proper way to re-instate those events?

View 1 Replies View RelatedI have a piece of javasacript code that searches through several iframes for buttons with specifi id's. When I find the button, I bind a click event to that button. This works perfectly fine in IE, but only works in Firefox if I alert something. After I click on the alert button ok, the click events are assigned correctly and the buttons work fine. See my code below for achieving this:
$.each(iframe, function(index, ifrm) {

I am working on a script to allow the user to click on an image to turn table header locking on and off. Everything appears to work fine, with the exception of one quirk that is occurring when I run the test page in Internet Explorer (7, in this case). If you click on the icon once to turn on header locking, it works. If you then click the icon again, it turns off header locking, as it is supposed to. But after that, you can no longer click on the icon. It is as if it loses the event binding. I am not removing or in anyway creating a new instance of the icon (although I did try using live() instead of click() just to be safe). Also, if I run this same page in Firefox, I do not have this problem. You can see the example page and view the complete source at [URL]
View 2 Replies View RelatedI'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:
in a table I want to have a specific click event (calling a function) for the first cell of each row and another function call e.g. for the third table cell.I assigned different class names to these cells and used this script:$("#tab_kat tr").find(".firstCell").bind("click", function() { ... });And the same for ".thirdCell".But is this possible without assigning class names to reduce the size of the code?Something like that:$("#tab_kat tr td.cells[1]").bind("click", function() { ... });
View 2 Replies View RelatedWe know that multiple calls to $(document).ready(); in the same page is possible.
I have a situation where another team implemented a $('#element').live('click', function() { /* Do this */} ); call on #element. I cannot modify this code, but I need to take an additional action on the same element on the same event. So, two actions will occur when #element is clicked.
I tried making $('#element').live('click', function() { /* Do that */} ); but this call does not fire.
It needs to be .live() since #element is being dynamically added.
Is there any way to add more actions to the same event on #element?
When I load my page I am using the .load() function to load a section of HTML from another .html file into the current page, as follows:
$(document).ready(function() {
$('#login_js').load('_HTMLCodeLibrary.html #loginform');
On the very next line I am attempting to bind a submit event handler to the form:
$('#loginform').submit(function() {
$.post('member.php', $(this).serialize(), function(data, status) {
data = eval('(' + data + ')');
if (data.msg) {
[Code].....
The form is loading fine, but for some reason the submit() is not getting attached to the form. Therefore when I submit it is running member.php from the form "action". Ultimately, I want to be able to run member.php from $.post() so that I can tell member.php that JavaScript is enabled.
I want to execute some code when a node is either selected or deselected but I only want specific nodes not the whole tree.
Normally, I think you bind an event when you create the tree like $ ('.sidecontent').bind(........).jstree(data.tree); but that's for the whole tree, which I don't want. I have a selector for the nodes I want like $('a[id*="room_1"]') but I don't know how to bind an event to those nodes only. Is this possible? If it is, then what event should I use?
I would like a function to be run whenever a variable is updated. I
have tried binding the onchange event to it, and it doesn't work. I
think I understand why, however, I would like to know if there is
anything that I can bind to my variable that will fire the specified
function whenever the value changes.
Is it possible to do this, or would I have to make a class for it?
