Calling the click function for button in jQuery

I am very new to jQuery and HTML. I am trying to create a button in html that uses jQuery to make the button to prompt alert message when clicked (rather than using onclick in html). In other words, I would like to use the jquery to call up the click function for the button and then return a pop up message.
I have my input type as "button" and my value as "Check" for my button in html.
Here's my code in javascript
$(document).ready(function(){
$("button").click(function(){
alert("Pop Out");
});
but nothing is showing up
Here's a fiddle to my code
http://jsfiddle.net/0ynbv233/8/

I have my input type as "button"
Like this?
<input type="button" />
In that case, this won't work:
$("button")
That selector is looking for button elements, not input elements. You can change the element:
<button />
or you can change the selector:
$('input[type="button"]')

I did what you have done and it worked for me.
Here is what my code was.
$(function(){
$("button").click(function () {
alert("Pop Out");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<button>Click Me</button>
Hope you figure out what you are doing wrong.

JQuery enabling a textbox with a button event query

I have a tiny issue if anybody can help... I am trying to implement a form, so when the page loads the textbox is disabled. If the user wishes to amend information they first have to press a button which will enable the text box.
<input id="text" type="text" disabled="disabled">
<br />
<button>Enable</button
So I have a basic textbox which is disabled. Then an event that should enable the textbox...
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("#text").attr("disabled","false");
});
});
</script>
I can get this working when the textbox is not initially disabled and I want to disable it, though I can not get it working the other way round - when it is disabled and I want to enable it.
Can anyone point me in the right direction?

Hi i have created a jsfiddle for you see the working example...
you should use removeAttr instead of attr
code:-
$(document).ready(function(){
$("button").click(function(){
$("#text").removeAttr("disabled");
});
});
link:-http://jsfiddle.net/L7S37/15/

You are giving boolean value as String
Use this
$("#text").attr("disabled",false);
instead of
$("#text").attr("disabled","false");
DEMO

Or you can use this, Even the last answer by Mr Soni is correct.
$(document).ready(function(){
$("button").click(function(){
$("#text").prop('disabled', false);
});
});

Javascript onclick not working on radio button

I have a problem with javascript. I have downloaded a rating star plugin , this one to be exact: http://www.fyneworks.com/jquery/star-rating/#tab-Testing
I have multiple things to rate on one page, so i thought i could use an onclick to send it to a function, that sends it to my database with ajax. The problem is, when a rating star is clicked nothing happens, ive tried it on a regular submit button and the function gets executed.
Here is the code :
<script type="text/javascript">
function postform(){
alert('Thing is clicked');
};
</script>
And the star is actually a radio button:
<input name="adv1" type="radio" class="star {split:4}" value="0.50" onclick="postform()"/>
I can't see what is wrong with the code, because when i test it on a regular button like this :
<input type="submit" value="testbutton" onclick="postform()"/>
It gives me the alert Thing is Clicked.
Somehow the star doesn't like the onclick stuff..
Ive tested it in IE, Chrome and FF, nothing ever happens
could someone help me out here?
Thanks alot!
Edit:
As requested by Lukas , i have this in my head :
<script type='text/javascript' src='jquery.min.js'></script>
<script src='jquery.MetaData.js' type="text/javascript"></script>
<script src='jquery.rating.js' type="text/javascript"></script>

That library is handling the onclick event of the radio button for you, so you cannot handle it by adding an attribute onclick to the input element.
According to their documentation you need to put some code like this in a script:
$('.auto-submit-star').rating({
callback: function(value, link){
alert(value);
}
});
Then add the class auto-submit-star to the class list of your radio button:
<input name="adv1" type="radio" class="auto-submit-star {split:4}" value="0.50" onclick="postform()"/>

jQuery UI modal confirmation dialog with ASP.NET not firing onClick event

jQuery newbie here. I've looked at dozens of similar questions on this site, as well as the answers provided so far here, all having pretty much the same response, and I've tried all of them, but nothing is working for me.
For the Javascript code in my .aspx, I currently have:
<script type="text/javascript" src="/resources/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="/resources/jquery-ui-1.8.20.custom.min.js"></script>
<link rel="stylesheet" type="text/css" href="/resources/ui-lightness/jquery-ui-1.8.20.custom.css" />
<script language="javascript" type="text/javascript">
$(function() {
var $myDialog = $("#cancelDialog").dialog({
autoOpen: false,
modal: true,
buttons: {
'Yes, cancel': function() {
$(this).dialog('close');
return true;
},
'No, resume editing': function() {
$(this).dialog('close');
return false;
}
}
});
$("[id$=btnCancel]").click(function(e) {
//e.preventDefault();
alert('boo');
//$myDialog.dialog('open');
});
});
</script>
The markup for "btnCancel" looks like this - notice that I don't have an "onClientClick" attribute because jQuery is supposed to do this for me, right?
<asp:Button ID="btnCancel" CssClass="btnCancel" runat="server" Text="Cancel"
CausesValidation="false" UseSubmitBehavior="false" />
And here's the markup I have for the cancellation dialog:
<div id="cancelDialog" style="display: none;" title="Please confirm cancellation">
<p>Are you sure you wish to cancel and abandon your changes?</p>
</div>
According to all the examples I've seen (and the answers provided here), this should give me a jQuery UI popup with my two buttons that just works. The page is no longer posting back when I hit the cancel button (due to the changes I made at Patrick Scott's suggestion). I could just use a standard Javascript confirm() dialog for this, but I want to be able to customize the prompts/styling.
The only other information I can think of to throw in is that this code is on an ASP.NET Wizard control (the cancel button is in the StepNavigationTemplate), but that shouldn't matter, should it?
Any hints as to what I need to change to get this working are greatly appreciated!
(question & code updated to reflect recent changes I've made)

The reason it isn't working is because the ID of the button changes when it's rendered to the page. To access the control in JavaScript, you need to use the ClientID property:
$("#<%= btnCancel.ClientID %>").click(function(e){
//open the dialog
});

Use $("[id$=btnCancel]") as your selector for the click event..
$= means ends with in the jquery selector, and webforms adds a bunch of stuff that will make your id not match.
$("[id$=btnCancel]").click(function(e) {
I also don't understand why you have the buttons declared separately from the rest of the dialog...
do this instead:
$(function() {
var $myDialog = $("#cancelDialog").dialog({
autoOpen: false,
modal: true,
buttons: {
'Yes, cancel': function() {
$(this).dialog('close');
return true;
},
'No, resume editing': function() {
$(this).dialog('close');
return false;
}
}
});
$("[id$=btnCancel]").click(function(e) {
e.preventDefault();
$myDialog.dialog('open');
});
});

you need to break it down - it sounds like there is another error in the JS somewhere which you don't see because the page is reposting. Try an alert on the click:
$('#btnCancel').click(function(e) {
alert('boo');
});
If this doesn't work you need to make the simplest script possible get that working and then add to it.

I figured it out! It turns out that <script> tags (nor most other tags, it seems) cannot be self-closed in HTML4 or HTML5. I was writing them like so:
<script type="text/javascript" src="whatever" />
when according to the standard, they must be written like so:
<script type="text/javascript" src="whatever"></script>
This was allowing my first <script> include to work (jquery-1.7.2.min.js), but following ones to fail. Weird, huh?
Here are some links with supporting information:
http://www.w3.org/TR/html4/interact/scripts.html#h-18.2.1 (the HTML4 specification)
Can the <script> tag not be self closed?
http://tiffanybbrown.com/2011/03/23/html5-does-not-allow-self-closing-tags/

<%=this.Page.ClientScript.GetPostBackEventReference(new PostBackOptions(this.Button1))%>;
Hook this to the "yes" button on your modal confirmation dialog. You'll need to change the ID according to your needs.

Executing Commands Javascript

I want to execute a command by the click of a button, and not when the page loads.
function hey() {
alert('bla');
}
Do I add something to the code above or to the button?
<input type="button" value="Click Me" onclick="hey()" />

Have you taken the time to type in your question into the magical Google box yet? Surely you'll see something like this:
<input type="button" value="Click me, now" onclick="hey()" />

Say you have the function that alerts a window to the user.
<script type="text/javascript">
function showMe() {
alert('You clicked on the button');
}
</script>
<button onclick="showMe()">Button</button>
This will make sure that the function is only called when the button is clicked upon and not when the page is loaded.

Okay, so you have a code that should work for alerting something on the click of a button. But you state that the code is running on page load. You have to check you code, looking for:
An onload attribute on the body tag, something like <body onload="hey()">
A call to hey somewhere else on your js code. Look for hey().
Maybe a reference to the button followed by a call to .click()
There is something else on your code causing the function to be called, you'll have to scan your code to find out what it is.
