within this specific function:
function VerifyUserInput()
{
var result = true;
if ($("#txtName").val().trim().length == 0) { result = false; $('#txtName').effect("highlight", {}, 1000); }
if ($("#txtSurname").val().trim().length == 0) { result = false; $('#txtSurname').effect("highlight", {}, 1000); }
if ($("#txtUserName").val().trim().length == 0) { result = false; $('#txtUserName').effect("highlight", {}, 1000); }
else {
var dataToSend = {}; dataToSend["username"] = $("#txtUserName").val();
$.ajax({
url: 'service.aspx?/isusernameexist/',
dataType: 'json',
type: "POST",
data: dataToSend,
success: function (responseData) {
if (responseData[0].cnt > 0) {
result = false; $('#txtUserName').effect("highlight", {}, 1000);
}
}
});
}
return result;
}
I am currently facing a challenge where I need to validate form data before adding a new user, however, the process of checking for available usernames through an AJAX request is causing timing issues. The function VerifyUserInput() ends up returning a value before the AJAX request is completed.
How can I effectively integrate AJAX functionality in such cases?
