元素拖动时调用多个函数 [英] call multiple functions when element is dragging

问题描述

我想在拖动一个元素时执行多种功能.我只是想问一问，在拖动一个元素时如何调用一个函数呢?这就是代码

I want to perform multiple functions when an element is dragged.I just want to ask how can i call more then one function when an element is drag.This is the code

$('#button').draggable(dragOpts);

var dragOpts = {
            start: function01,
            drag: function01
};

是否可以在拖动时调用两个函数，例如

is this Possible to call two functions at dragging such as

var dragOpts = {
            start: function01,
            drag: function01,function02
};

推荐答案

您需要在拖动事件中调用您的2个函数. 这是代码

you need to call your 2 functions inside drag event. here is code

var dragOpts = {
            start: function01,
            drag: function(event,ui){
function01(event,ui);
function02(event,ui);
}
};
