如何从.cs页调用javascript函数 [英] How to call a javascript function from .cs page

问题描述

我的.aspx页中有一个javascriipt函数.如何从.cs页调用此函数，以便该函数接受在页面加载时从.cs页发送的参数?请在这方面帮助我.

预先感谢.

解决方案

您可以使用以下函数从服务器端调用javascript函数.

已更新:
您的javascript函数:

函数初始化(文件名){ var  elem = document.getElementById("  aaa")； elem.filename = ' "+ fileName +"'; } 

您的aspx.cs页面:

 字符串 fileName = " ;
ScriptManager.RegisterStartupScript(此 .Page，此 .GetType()，  ScriptRegistration"， 初始化('" + fileName +  ');"，投票"，如果这是正确的答案，请提供"接受答案".:rose:



谢谢，

您无法从.cs页面调用它，但是您可以将引用传递给c#代码，然后执行该代码并传递回JS脚本.

从任何事件(例如按钮单击或页面加载或任何其他事件)中调用以下代码段

字符串filename =分配值"；

 sb = new System.Text.StringBuilder();
        sb.Append(@"脚本 语言  ='  javascript' > )；
        sb.Append(@"Initialisation('" +文件名+');");
        sb.Append(@"/script  
 

Hi,

I have a javascriipt function in my .aspx page. How can I call this function from .cs page, so as that the function accepts a parameter that I send it from .cs page on page load? Please help me in this regard.

Thanks in advance.

Hi,

You can call javascript function from server side using following function.

Updated:
your javascript function:

function Initialisation(fileName) { var elem = document.getElementById("aaa"); elem.filename = '"+fileName+"'; }

your aspx.cs page:

string fileName = "test.aspx";
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "ScriptRegistration", "Initialisation('"+ fileName +"');", true);

Please do let me know, if you have any doubt.

You can''t call it from the .cs page, but you can pass the reference to the c# code which can then execute and pass back to the JS script.

Call below code snipet from any event like button click or page load or any other event

string filename="assign value";

 System.Text.StringBuilder sb = new System.Text.StringBuilder();
        sb.Append(@"<script language='javascript'>");
        sb.Append(@"Initialisation('" + filename + "');");
        sb.Append(@"</script>");
        System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "JCall1", sb.ToString(), false);
