I have a function:

reportAdminActions.reportMemberList(project, function(data) {
    console.log(data);
}); 

This function is called by another ajax operation like these:

reportMemberList: function(projectId, callback) {
    var projectDetail = new Object();
    projectDetail.projectId = projectId;
    var pluginArrayProject = new Array();
    pluginArrayProject.push(projectDetail);   
    $.ajax({
        url : ConfigCom.serverUrl + 'projectreportonmember',
        dataType: "jsonp",
        type: "POST",
        data: JSON.stringify(pluginArrayProject)
    }).always(function(data) {
        callback(data.responseText);
    });
}

I need return value to function defined area after ajax operation. But here I got a error

• I am not sure but i doubt it is because of your JSONP – Vigneswaran Marimuthu Commented May 7, 2015 at 11:15
• Bad luck. It is not working when i removed JSONP. – jagadeesh puthukkudi Commented May 7, 2015 at 11:18
• could you please post the sample of your server response? – smnbbrv Commented May 7, 2015 at 11:20
• It is JSON Response [{"timesheet_user_id":"5","timesheet_hours":"4","name":"jagadeesh puthukkudi"},{"timesheet_user_id":"8","timesheet_hours":"7","name":"admin admin"},{"timesheet_user_id":"5","timesheet_hours":"2","name":"jagadeesh puthukkudi"}] – jagadeesh puthukkudi Commented May 7, 2015 at 11:32

Check the rest of your code for calls to reportMemberList and make sure you always call it with the callback as a parameter. If you omit the callback parameter anywhere (e.g. call reportMemberList with just the projectId parameter), the code above would parse correctly the other calls to the function with the callback would produce the error. (This was the solution for me.)

guessing, but try to change your "jsonp" to "json". If you don't make cross-origin requests there, it should work

reportMemberList: function(projectId, callback) {
    var projectDetail = new Object();
    projectDetail.projectId = projectId;
    var pluginArrayProject = new Array();
    pluginArrayProject.push(projectDetail);   
    $.ajax({
        url : ConfigCom.serverUrl + 'projectreportonmember',
        dataType: "json",
        type: "POST",
        data: JSON.stringify(pluginArrayProject)
    }).always(function(data) {
        callback(data.responseText);
    });
}
