I'm having trouble seeing what's wrong with my code. I'm trying to select my list items, but they don't seem to get selected.
Here's my HTML
<!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Tasklistr</title>
<style type="text/css"> @import url(styles.css);</style>
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js'></script>
<script type="text/javascript" src="application.js"></script>
</head>
<body>
<h1>JSTasker</h1>
<form>
<fieldset>
<legend>Add a Task</legend>
<input type='text' name='task_text' id='task_text' />
<input type='submit' name='add_button' value='Add' id='add_button' />
</fieldset>
</form>
<div id='tasks'>
<h2>Your Tasks </h2>
<ul>
</ul>
</div>
</body>
</html>
My application.js
$(document).ready(function() {
$('input#add_button').click(function(event) {
event.preventDefault();
var task_text = $('input#tas开发者_Python百科k_text').val();
var task_item = "<li><p>" + task_text + "</p></li>"
$('div#tasks ul').append(task_item);
$('input#task_text').val(null);
});
$('input#task_text').focus();
$('div#tasks ul li').click(function() {
alert("Hey");
});
});
You should use .live() instead of .click().
You are currently binding a click event to DOM-elements that don't exist at the time of binding (since you are adding them by clicking the button). live() solves this problem: events bound by this method also work for elements that are created after live() is called.
Example:
$('div#tasks ul li').live('click', function(){
alert("Hey");
});
