Question

我想在运行时在 div 上添加可拖动功能。 div s id 是通过以下代码生成的 :

var Exp=0;
view.renderFunction = function(id1){
  var id= id1 + Exp++;
  $("#"+id).draggable();
};

This is my function where the id is dynamically generated when I drop div. But when I apply the draggable method it can t move. How can I move div?

Answer 1

我用动能.j.js,现在工作正常

Answer 2

它会工作,已经测试了这一点。

确保以下各点:

Make sure you know what is Exp++ (you haven t mentioned about it in the question)
The element on which you call draggable() is a valid DOM element.
Try calling it on document ready or DOM ready

Answer 3

Are you facing trouble with dragging itself or is the problem only with dropping it anywhere? This should be pretty straight forward. Here is a sample that shows dragging a child div from one parent div to another: How to enable dragging a div from one parent div to another

Answer 4

var id= id1 + Exp++; 
$("#"+id).draggable();

Exp/code> 是什么, 您是否确定您正在对现有元素调用 . drggable () ? 另外, 您是否曾经使用 id 来调用此功能?
