Getting Textarea Value with jQuery

问题:

This is driving me crazy - why doesn't my code work?

Click               jQuery("a#send-thoughts").click(function() {                 var thought = jQuery("textarea#message").val();                 alert(thought);             }); 

alerts undefined.

回答1:

you have id="#message"... should be id="message"

By using new version of jquery (1.8.2), I amend the current code like in this links http://jsfiddle.net/q5EXG/97/

By using the same code, I just change from jQuery to '$'

Click   $('#send-thoughts').click(function() { var thought = $('#message').val();   alert(thought); });

It can be done at easily like as:

     Click                $("a#send-thoughts").click(function() {             var thought = $("#message").val();             alert(thought);         });

change id="#message" to id="message" on your textarea element.

and by the way, just use this:

$('#send-thoughts') 

remember that you should only use ID's once and you can use classes over and over.

try this:

Click               jQuery("a#send-thoughts").click(function() {                 //var thought = jQuery("textarea#message").val();                 var thought = $("#message").val();                 alert(thought);             });
