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);
