JavaScript 访问 c#变量的方法

问:
Hi,

I have this C#/ASP.NET/.aspx page with a string variable named myString with the value "Mario Gamito".

How can I access "Mario Gamito" from within a JavaScript function, i. e., the variable's value ?

Already tried '" + mystring + "' but it doesn't works.

Any help would be appreciated.

you can also try pushing the variable to javascript using the registerClientScriptBlock

string  jsVariable  =   string .Empty;
string  mySting  =   " Mario Gamito " ;

jsVariable  =   " var myjsString =  "   +  myString;


this .Page.ClientScript.RegisterClientScriptBlock(
                     this .GetType(),  " YourStringVar " , jsVariable,  true );
