$.ajax的success中如何添加代码var drag = function(obj) { obj.bind("mousedown", start); function start(event) { if (event.button == 0) { gapX = event.clientX - obj.offset().left; gapY = event.clientY - obj.offset().top; $(document).bind("mousemove", move); obj.bind("mouseup", stop); } return false; } function move(event) { obj.css({ "left": (event.clientX - gapX) + "px", "top": (event.clientY - gapY) + "px" }); return false; } function stop() { $(document).unbind("mousemove", move); $(document).unbind("mouseup", stop); } } obj = $(".image-editor"); drag(obj);

可以这样添加代码：

$.ajax({
  url: 'your-url',
  success: function(response) {
    // your other code
    var drag = function(obj) {
      obj.bind("mousedown", start);
      function start(event) {
        if (event.button == 0) {
          gapX = event.clientX - obj.offset().left;
          gapY = event.clientY - obj.offset().top;
          $(document).bind("mousemove", move);
          obj.bind("mouseup", stop);
        }
        return false;
      }
      function move(event) {
        obj.css({
          "left": (event.clientX - gapX) + "px",
          "top": (event.clientY - gapY) + "px"
        });
        return false;
      }
      function stop() {
        $(document).unbind("mousemove", move);
        $(document).unbind("mouseup", stop);
      }
    }
    obj = $(".image-editor");
    drag(obj);
  }
});

这样，在ajax请求成功后，会执行success回调函数内的代码，其中包括了你提供的拖拽函数。
