Question

Answer 1

+2 A:

Change it to:

$.post("chat.php", { msg:text } );

jQuery expects the data to be passed as an object and { ... } will essentially create an anonymous object for us. msg:text -- without the curly braces -- unfortunately doesn't do much and will throw and error at runtime.

So putting the two together: { msg:text } creates an anonymous object with a property of msg populated with the value of your text variable.

Answer 2

A:

You're doing it wrong, use a proper JSON object:

$.post("chat.php",  { msg:text });

It is not a JSON object. It is a plain old literal JavaScript object ;)

Well, guess you're right :)

Answer 3

A:

You forgot the curly braces round the data parameter of $.post

$.post("chat.php",{msg:text});

Answer 4

+1 A:

Parameters are passed as an array:

<head>
<script type = "text/javascript" src = "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"&gt;&lt;/script&gt;
<script type = "text/javascript">
     function yo() {
       var text = $("#msg").val();
       $.post("chat.php", {msg:text});
     }
</script>
</head>
<body>

<input type="text" id="msg" onkeyup="yo()">
<div id="display">Change</div>            
</body>
