为什么该功能没有运行？

Question

  $('.posts li img').each(function() {
    if( this.complete )
      imageResize($(this), 64, 64);
    else
      $(this).load(imageResize($(this), 64, 64));
  });

I tried adding "alert('test')" to imageResize(), but it isn't working. Is there any reason why imageResize() isn't being called?

Answer 1

使其功能：

$(this).load(function(this) {imageResize(this, 64, 64)});

Answer 2

Not sure that this is the problem, but it's certainly a potential problem. The second imageResize() call will be executed immediately and the return code used as the handler for the load event. You need to wrap it in an anonymous function and use that instead, eg

  $('.posts li img').each(function() {
    if( this.complete )
      imageResize($(this), 64, 64);
    else
      $(this).load(function() {imageResize($(this), 64, 64);});
  });
