jQuery: form, function and give attribute

I have a form that on action: action="javascript:DoWallInsert($idf );"..

Now on this form i have this submit button. I want onclick that it should be disabled, and then enabled again on success (the ajax call inside the function).

<input name="submit" type="submit" id="submit" value="Send">
function DoWallInsert(BuID, uID){
       $('#submit').attr('disabled', true);
  var wrapperId = '#wall_insert';
    $.ajax({ 
       type: "P开发者_StackOverflow社区OST",
       url: "misc/insertWall.php",
    data: {
    value: 'y',
    BuID : BuID,
    uID : uID,
    message : $('#message').val() 
    },
       success: function(msg){
$('#submit').attr('disabled', false);
     $(wrapperId).prepend(msg);
     $(wrapperId).children().first().slideDown('slow');
     $('#message').val("");
        }
     });
}

I tried this, but it doesnt work

You need to remove the disabled attribute you added earlier (there is no enabled attribute), so replace this:

$('#submit').attr('enabled', true);

With this:

$('#submit').attr('disabled', false);

To enable a button:

   // $('#submit').attr('enabled', true);  //incorrect
   $('#submit').removeAttr('disabled');
   //or $('#submit').attr('disabled', false);
