问题描述
直接调用JavaScript函数(如onclick ="a()")和onclick ="JavaScript:a()"(其中a()是用JavaScript编写的函数)有什么区别?
What is the difference between calling a JavaScript function directly like onclick = "a()" and onclick="JavaScript:a()" where a() is a function written in JavaScript?
推荐答案
onclick = "a()"
这是在以* .ASPX或* .ASCX之类的设计器表单页面编写时(即在客户端编写时)完成的.
类似的方法可用于通过脚本语言(例如Javascript或类似语言)来定义点击.
This is done while writing in designer form page like *.ASPX or *.ASCX, i.e. while writing in client side.
Similar approach can be used for defining click via script language like in Javascript or so.
onclick="JavaScript:a()"
这是在编写代码隐藏文件时完成的.他们驻留在服务器上，需要知道方法a()的执行是在客户端执行的，并且是在脚本中定义的.
This is done while writing in code-behind files. They reside on server and needs to know that the execution of method a() is client side and defined in scripts.
