JavaScript 访问 c#变量的方法

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.

public partial class Default2 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

string mySting = "Mario Gamito";

this.Hidden1.Value = mySting;

}

答2：

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);
