Question

I have to call the web service using java script? e.g. I’m creating one app in HTML. In that I want to check user name and password in server machine(computer) and I want to collect the result from the server. Here I’m passing three arguments like user name, password and login mode(windows or others) then it’s sent to server and it returns json result then I parse the json result and then I’m binding in to a list.
so I got output in jQuery.

// Make the dataobject based on the credentials 
            var dataObject = {}; 
dataObject = {Username:uname,Password:pword,Domain:domain,WindowsUser:windowsuser};

//webservice

$.ajax({
        type: "POST", 
        url:"../REST/session.aspx?_method=put",
        data: JSON.stringify(dataObject, null,4),
        cache: false,
        dataType: "json",
        success: onSuccessLogin,
        error: function (xhr, ajaxOptions){
                alert(xhr.status + " : " + xhr.statusText);
            }    

    }); 

function onSuccessLogin(data)
{

    alert("success");
    $.mobile.pageLoading();

    //Parse the vault result
    parseResults(data);
}

then I successfully parsed. Here I want to change the web service because Non touch mobiles doesn’t support the jQuery. so that I’m changing that web service.

I think what you are searching for is “XMLHttpRequest”. You can make an asynchronous call with it to your webserver, collect the results and parse it. You don’t need a special JavaScript Framework for that. In fact, every Ajax API uses the XMLHttpRequest Object.

There are many easy Examples on the web how to do that.
