将属性链接到创建它的元素 [英] Linking a attribute to element it is created

问题描述

亲爱的先生，

我希望在javascript创建元素时将事件''onchange''链接到元素。我知道javascript有函数''setAttribute''，而jquery有''attr''函数。我希望无论何时创建新元素页面都没有加载，属性链接到该元素并且我知道该元素的id提前

我想这样做，因为我无法控制元素的创建，但我知道该元素创建的id。我希望每当这个元素创建一个属性时都链接到它''' onchange''

如果有人有任何解决方案请告诉我

I know javascript have function ''setAttribute'', and jquery have ''attr'' function.i want whenever the new element is created page is not loaded , an attribute is linked to that element with considation i know the id of that element in advance

推荐答案

使用jQuery非常方便：

It''s very conveniently done with jQuery:

myElement = // create it as you already do
myElement.change(function() {
   // handle the event here
});
