Question

I would like to pass 2 javascript string arrays
“myArray1” and “myArray2” from ajax to a webmethod. What I have is the following which is not working.

var myArray1 = new Array();    
var myArray2 = new Array();    
// the arrays are filled further in the code.   
// call to the webmethod:
$.ajax({
        type: "POST",
        url: "mypage.aspx/SavePage",
        data: ??????,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            alert(msg.d);
        },
        error: function() {
            alert("failed");
        }
    });

I do not know how to pass these arrays in the data: part of the call.

C# part of my code.

public static string SavePage(List<string> myArray1, List<string> myArray2)
{
}

Try this way:

data: "{'myArray1':"+JSON.stringify(myArray1)+",'myArray2':"+JSON.stringify(myArray2)+"}",

In your codebehind :

[System.Web.Services.WebMethod]
public static string SavePage(List<string> myArray1, List<string> myArray2)
{
return myArray1;
}
