Question

I m试图revert,如果情况有误,则可以提取。例如,我要做以下工作:

new Draggable( myelement , {
    onStart: function() {
      // do something
    },
    onEnd: function() {
      var condition = getConditionVal();
      if (!condition) revert to original position
      else {
         // do something else
      }
    }
});

这是可能的吗? 不能肯定“可耕地”会在这种情况下发挥作用,因为可耕地的变化动态。

Scriptaculous drag/drop is designed to have all kinds of fancy stuff easily added. Of course you can edit the revert option any time.

2. 改变重整重整的重整价值,只是重新选择:

var myDraggable = new Draggable( myelement , {
    onStart: function() {
      // do something
    },
    onEnd: function() {
      var condition = getConditionVal();
      if (!condition){
          myDraggable.options.revert = true;
      }
      else {
          myDraggable.options.revert = false;
          // do something else
      }
    };
});

Scriptaculous does the revert right after the onEnd event call, which gives us the possibility of changing it before it will be executed.

硬体 s/软体代码是旨在有条件恢复的。你本可以回过来,或者不会再回头。令人痛心的是,这一切都是如此。

这一特征多次被请求,但多年来,文字/宣传型已越来越受欢迎,因此,令人怀疑这一特征会增加。
