Accessing C# method in a JavaScript function
How can i execute a C# method in a java script function? Is开发者_如何学Python it possible?
Not really. If you server is located in the USA, and a user visits your site from China, your C# code will execute in the USA, and your JavaScript code will execute several moments later (~ 500ms later probably) in China. When the JavaScript code begins its execution, the C# script that ran on the USA server will be long forgotten and terminated.
Your best bet is probably to communicate back to your server through Ajax, as @David suggested in the other answer.
What you can do is fire an AJAX call that executes a C# method on the server, and hands back the result to the javascript.
AJAX is best handled with a javascript framework such as jQuery.
Yes it is possible to access the server side methods in C# using Javascript For all you need to use write a static function in the server side and call it using PageMethods.
at Client Side
PageMethods.FunctionName(para1,pageMethodError)
Here the condition is to pass pagemethoderroe as a parameter to return the function fails
PageMethods.Get(Id,
function(result) {
$(.res).html(result);
}
}
}
, pageMethodError);
pageMethodError=function(error){
//code if failed
//error will return error message
}
at server side
[System.Web.Services.WebMethod]
public static object Get(string ID) {
return "hai";
}
for more abt the parameters for a Page method plz refer to http://aspalliance.com/1922_PageMethods_In_ASPNET_AJAX.3
This method is also using Ajax and it will post your request to the server and the server responds in the form of JSON [JavaScript object notation].So there is no problem if your server is located in US and accessing from China
