Why Doesn't My Button Click Event Fire?
Nov 16, 2006
I'm new to JavaScript and I wrote this code to play with. Oddly, if I
enter text in a box and then press the button, I only get the onChange
event for the text box and not the button's onclick event. But if I
press the button without entering text first, the button click event
does work. What's up?
<html>
<body>
<h3>Events on Buttons and Text Boxes</h3>
<input id="myTextBox1" type="text" onChange="doChange1()" /<br />
<input id="myTextBox2" type="text" onChange="doChange2()" /<br />
<input id="myButton" type="button" onclick="doClick()" value="Click me"
/>
<script type="text/javascript">
function doChange1(e)
{
var val = document.getElementById("myTextBox1").value;
alert("You typed: " + val);
}
function doChange2(e)
{
var val = document.getElementById("myTextBox2").value;
alert("You typed: " + val);
}
function doClick(e)
{
var _num = prompt("Enter a number", "100");
alert("You typed: " + _num); // number converted to string
automatically
}
</script>
</body>
</html>

After doing some tutorials, I am not sure if this is a bug, or perhaps someone can give me a better explination why it is working the way it is.I am using Visual Studio 2010 combined in a Master Page. In my aspx page, I have the following code:
<script type="text/javascript">
$(document).ready(function () {
$('input:text:first').focus();
[code]....

I want to execute a function, when a user clicks on a certain button on my page. It works in Chrome, Safari, Opera and FF, but not in IE 9. The jquery-Code looks like this:
$('#mapButton').click(function(event){ ... });
My HTML source code:
<div id="medias">
<div>AUDIO<br /><p id="audioButton"></p></div>
<div>KARTE<br /><p id="mapButton"></p></div>
<div>BILDER<br /><p id="galleryButton"></p></div>
<br style="clear:both"/>
</div>
By Clicking on mapButton the function should follow. I tried it first with the input-Tag, then with the a-Tag and afterwards with the p-Tag. Nothing works at all. I also inserted a return false at the end of my JS function. How to handle it?

I'm new to jQuery. I'm writing some code to show a picture if user clicks on table row. This is the table
<table id="restable" border="0">
<thead><tr>
<th class="cat" width="150"><a href="">Category</a></th>
<th class="brand" width="150"><a href="">Brand</a></th>
<th class="name" width="300"><a href="">Name</a></th>
<th class="weight" width="50"><a href="">Weight</a></th>
</tr></thead>
<tbody id="table">
</tbody>
</table>
The table is filled with this function
function search(sortt,dirt) {
$.getJSON("/jsonsearch.php", {cat: $("select#catselect").val(), brand:
$("select#brandselect").val(), name: $("input#search").val(), sort:
sortt, dir: dirt}, function(j){
$("tbody#table").empty();
var row='';
for (var i = 0; i < j.length; i++) {
row="<tr><td width='150'>"+j[i].cats+"</td><td width='150'>"+j
[i].brand+"</td><td class='name' width='300'>"+j[i].name+"</td><td
width='50'>"+j[i].weight+"</td></tr>";
$("#restable tbody").append(row);
}})
This is the function I put inside $(document).ready()
$("#table td").click(function(){
alert("jhgjgh");
});
The problem is that click event doesn't fire. If I get it working, how do I get the contents of the row that user clicked. I need Name from that row.

The Problem: So a user clicks on "web development" for example. This triggers the mousedown function correctly. The user then clicks on "web development" again. This no longer triggers the mousedown event. BUT if you move the mouse around or click a different link it will trigger the function correctly.
The HTML:
<body>
<div id="animate-top">�</div>
<div id="wrapper"><a href="#" class="menu">Graphic Design</a><a href="#" class="menu">Web
Development</a><a href="#" class="menu">Contact Us</a></div>
</body>
The Javascript:
$("a").mousedown(function () {
if (topvisable == 0){topvisable = 1;
$("#animate-top").slideUp('slow');
} else {topvisable = 0;
$("#animate-top").slideDown('slow').delay(1000).slideUp('slow');
}
return false;
});

I want to call the click event of the link (anchor tag) on the click of the button. I used this code below in the click event of button to call links click event and it works fine in IE.
document.getElementById('linktag').click();
But, this doesn't work in Firefox. I googled a bit and found that in firefox, you have to do something more to achieve this behaviour. So, I ended up doing this on button click to work in firefox:
var link=document.getElementById('linktag');
var e = document.createEvent('MouseEvents');
e.initEvent(
[code]....
The above code does the click on link when I click on the button. But my problem now is that I have defined a link as
<a href="mailto:abc@xyz.com?subject=abc&body=email body">email </a>
and when click is called and mailto links opens my email client, it somehow ignores the subject and body parameters of the link. It works properly when i actually click a link element. but it doesn't work when i simulate the click event by code written above. above dispatching event code somehow ignores the link parameters?

I have an object that has a click event I'm trying to trigger. However in the click event I have the following if statement:
if(event.button != 0){return true;}
This if statement allows right clicks to go through and activate but it also prevents me from triggering the event. Any ideas on how to prevent this? If I remove the if statement from the first click function everything works as intended.Here's my example code based off of the trigger event examples:
<!DOCTYPE html>

We are developing an Ajax based application. In this application the
URL is fixed and as user navigates on the application we will change
Anchor on the URL so that user can bookmark the url and can load the
page on demand.
When user refreshes the page we have no issue in the populating the
page based on the anchor in URL as on load we can capture the
hash(#anchor) and act accordingly.
sample URL: http://www.google.com/somecontext#<anchor>
When the user clicks back button anchor is changing but not able to
know where to get callback.
Is there any event or way I can find when the user has clicked back
button.

I'm making a Vacation Rental application and it works... for the most part. The following will describe what a property owner will be doing when they subscribe to this site to add their vacation rental property to the site.
They first enter information about the Property Site itself, location, address.etc., and then they add specific attributes about the property, such as how many rooms are in the house, bathrooms, accommodations, etc.
Here's an image for the page:
When the "Add Button" button is clicked, it opens a jQuery dialog to allow the site owner to enter information about the room, such as the Room name, description, how many it sleeps, etc. This all works, for the most part.
Here's a shot of the dialog:
When the site owner clicks the "Save" button, the data in the dialog is sent to the server via Ajax (Json). Again this all works.
After a successful transaction, the server controller returns HTML of the table of rooms for this property site and then the jQuery success option replaces the existing HTML table with the new table that has the new row that includes the new room information.
Again, this does work.
What doesn't work completely correctly is, in each row of the table are buttons to "Edit" the room, or "Manage Beds" for the room, and after the table is dynamically replaced via the jQuery script, the button click events in each row are no longer bound.
So it's the "Manage Beds", "Edit" and "Delete" buttons that lose their event binding after the HTML table is replaced when a new Room is added or edited.
Is there a way to re-bind the button events after the table is replaced? I'd really like this to be bullet-proof.

I wanted to show a datepicker on a custom click event. i can't use datepicker button or image due to lack of space and certain other restrictions.
I have created a custom button with a custom look and feel. i want the click event on this button to trigger datepicker display.
I tried to use:
But this is merely associating the textfield datepick with datepicker, its not showing it.. rather we have to click on textfield after the button click to show the datepicker.
I also tried:
But this also did not do any changes..
Any possible way for getting this event..

I have a disabled submit button sitting in the fieldset of a form. What I'd like to do is attach a click event to this button, but from what I understand this can't be done since you can't attach events to disabled elements.
Is it possible to attach it to the fieldset? I'm not completely familiar with event bubbling but maybe it's possible to capture the element clicked?

I have set up a JSFiddle to demonstrate what is happening:[URL]... Basically if All content types is checked already and is clicked when checked then searchAjax should not be invoked. It currently invokes the function. When it is not checked and clicked then it should behave as it is now (disable sibling radio button and uncheck all associated checkboxes).

I have an Ajax post that gets 100 records. That runs a callback function called Update(data.d) that loops through and populates a Div container with these records each in their own Div with numbered IDs. (It also removes old Divs so that there are never more than 100 n the container. During this loop I register the click event for each <a> called'Like':
$("#" + items.id + " .vLike").click(function () {
if (this.innerHTML == "Processing') return;
SendLike(items.id);
