从ASP页面调用函数背后的代码 [英] Call a code behind function from ASP page

问题描述

您好，我一直在尝试在C#函数后面调用代码，即链接href中的Button click().我尝试了几种解决方案，甚至创建了一个名为按钮单击功能的javascript函数，并且在href中我调用了javascript函数，但到目前为止仍未找到任何解决方案.页面上什么都没有发生，所以在我实际调用函数背后的代码之前，这是我的事:

ASP页面:

javascript:

Hello I''ve been trying to call a code behind C# function, that is a Button click() from a link href. I''ve tried several solutions, even created a javascript function that called the button click function, and in the href I call the javascript function but still so far haven''t found any solution. Nothing is happening in the page so before I can actually call the code behind function, here''s my deal:

ASP Page:

javascript:

function click() 
{
   alert("HEY");

}

HREF:
< a href =#" class ="button" onclick ="javascript:click();">< span>卡片</span</a>

或

< a href ="javascript:void(0)" class ="button" onclick ="click()">< span>卡片</span</a>


是否有人作为解决方案要么从href调用函数背后的代码，要么仅从href调用javascript函数?

谢谢

已从答案中移除:
javascript dopostback实际上使我前进了一些.我遵循此页面中的示例:
http://wiki.asp.net/page.aspx/1082/dopostback-function/ [< ^ ]
该页面正在执行回发，但未输入codebehind函数.
仍然需要帮助！

HREF:
<a href="#" class="button" onclick="javascript:click();"><span>Cards</span</a>

or

<a href="javascript:void(0)" class="button" onclick="click()"><span>Cards</span</a>


Does anyone as any solution either to call a code behind function from a href, or to just call a javascript function from href?

thank you

Moved from answer:
The javascript dopostback actually made me advance a little more. I follow the example in this page:
http://wiki.asp.net/page.aspx/1082/dopostback-function/[^]
The page is doing the postback but is not entering the codebehind function.
Still need help!

推荐答案

您好，

您可以从href调用javascript函数.使用以下代码:

Javascript:

Hello,

You can call a javascript function from href. Use the following code:

Javascript:

function Hello() {
    alert("Yor code goes here....");
}

HTML:

HTML:

<a href="#" onclick="javascript:Hello();"><span>HELLO....</span></a>

要在函数后面调用代码，请参考以下链接:

如果要从javascript调用函数代码，而不是在javascript do_postback方法上进行搜索.您会找到自己的方式.

Hi,

If you want to call function code behind from javascript than search on javascript do_postback method. You will get your way.

//If you are databinding then
<a href="<%# GetURL(Eval("VideoCategoryID")) %>">

//If not

<a href='<%= GetURL(Eval("VideoCategoryID")) %>'>

//method from codebehind
protected string GetURL()
        {
            string path = "codeproject.com";
            return path;
            
        }</a>
