Question

i.e.

$("#savenew").live( click , function(e)  {
               var user=<?php echo $user?>;
                 $.ajax({
                type: "POST",
                url: "actions/sub.php",
                data:{user: user} ,
                success: function(){
                  $( #savenew ).html( <span>Unsubscribe</span> );
    $(this).attr( id ,  clean ); // this my problem my problem
                        }
            });
     });

在“雅氏”要求之后的id,并没有从拯救到清洁,但html完全是罚款的,因此知道“雅氏”要求正在发挥作用。问题是什么?

Answer 1

You just need to save the context (via the context option for $.ajax()) so this still refers to #savenew, like this:

$("#savenew").live( click , function(e)  {
  var user=<?php echo $user?>;
  $.ajax({
    context: this, //add this!
    type: "POST",
    url: "actions/sub.php",
    data:{user: user} ,
    success: function(){
      $(this).attr( id ,  clean ).html( <span>Unsubscribe</span> );
    }
  });
});

还指出,这使得你能够把物品链起来并清理起来。

Answer 2

。

如上行,你需要参考:

$( #savenew ).attr( id ,  clean );
