Jquery在函数之间传递参数

问题描述

嘿，我想从jquery中的函数传递一个参数，但我不能让它工作。我究竟做错了什么？我想将点击功能中的名称传递给对话框功能以防止重复代码

Hey i would to pass a parameter from a function in jquery, but i cant get it to work. what am I doing wrong? I would like to pass "name" from the click function to the dialog block function to prevent repeating of code

更新：我已定义名称功能之后。然而，我仍然不能像这样传递<％= GetUserName（name）％>

Update: I have define name after the function. however i still cannot pass it like this <%=GetUserName(name)%>

推荐答案

因为您未能定义使用 var 关键字命名，它已被页面上的任何其他代码访问。

Because you failed to define name with the var keyword, it is already accessible by any other code on the page.

除了这种特殊情况，变量具有函数范围，因此在高于需要访问它的两个函数的级别定义 var name ... 。

Other than this special case, variables have function scope, so define a var name... at the level higher than both functions that require access to it.
