I have used the jquery ajax for getting the values from the server.when the method goes into the ajax success or error, i need to return the value.How to do that.Please guide me.

$.ajax({
    cache: false,
    async: true,
    type: "GET",
    timeout:6000,
    dataType: "json",
    url:url +"log",
    data: { ContactEmail : $("#username").val()},
    contentType: "application/json;charset=utf-8",
    success: function (result) 
    {
        //Here I need to return the result and should get in another method
    },
    Error: function (e)
    {
        //Here I need to return the result and should get in another method
    }
});

for example
when i called the checkNetConnection() ,it return the value.i need like this

function checkNetConnection() 
{
        var netresult=0;
        var networkState = navigator.network.connection.type;
        var states = {};
        states[Connection.UNKNOWN]  = 'Unknown connection';
        states[Connection.ETHERNET] = 'Ethernet connection';
        states[Connection.WIFI]     = 'WiFi connection';
        states[Connection.CELL_2G]  = 'Cell 2G connection';
        states[Connection.CELL_3G]  = 'Cell 3G connection';
        states[Connection.CELL_4G]  = 'Cell 4G connection';
        states[Connection.NONE]     = 'No network connection';
        if(states[networkState]=='Ethernet connection'||states[networkState]=='WiFi connection' || states[networkState]=='Cell 2G connection' || states[networkState]=='Cell 3G connection' || states[networkState]=='Cell 4G connection')
        {
            netresult=1;
        }
        else
        {
            netresult=0;
        }
        return netresult;
}

Answer 1

Your results are stored in variables result and e:

...
success: function (result) 
    {
        // result contains the results
        foo( results );
    },
    Error: function (e)
    {
        // e contains the error
        bar( e );
    }
...

// Function to do something with the returned results
function foo( someData ) {
  // do stuff
}

// Function to do something with the error
function bar( someErrorData ) {
  // do stuff
}

A quick way of seeing the data is to display it using alert: alert( results ) or alert( e ) instead of the function calls.
