求问jQuery中delegate 和on的区别？

Question

// jQuery 1.4.3+
$( elements ).delegate( selector, events, data, handler );
// jQuery 1.7+
$( elements ).on( events, [selector], data, handler );

求问 delegate 和on的区别只是参数顺序吗？如果只是参数顺序的话，觉得没必要去更新方法哈

官方文档已经不推荐使用.delegate()了

.delegate() has been deprecated. It was superseded by the .on() method since jQuery 1.7, so its use was already discouraged.

更新答案，题主举的例子中，结果是一样的:

.on() 的语法有两种情况:

1.此时效果跟.bind()、.click()是一样的。

目标元素.on('click',handler);

2.而下面这种情况，确实跟 .delegate()是一样的。          

代理元素.on('目标元素选择器',handler);
