Hey! New to these forums, but I just started web dev and about to finish the book. I am having a hard time with one thing. Well, the entire Ajax chapter is hard for me, but one part in particular I don't understand, it is a chunk of code inside the login.js for the section.
// Create an object of Ajax options:
var options = new Object();
// Establish each setting:
options.data = data;
options.dataType = 'text';
options.type = 'get';
options.success = function(response)
{
// Worked:
if (response == 'CORRECT') {
// Hide the form:
$('#login').hide();
// Show a message:
$('#results').removeClass('error');
$('#results').text('You are now logged in!');
} else if (response == 'INCORRECT') {
$('#results').text('The submitted credentials do not match those on file!');
$('#results').addClass('error');
} else if (response == 'INCOMPLETE') {
$('#results').text('Please provide an email address and a password!');
$('#results').addClass('error');
} else if (response == 'INVALID_EMAIL') {
$('#results').text('Please provide your email address!');
$('#results').addClass('error');
}
}; // End of success.
options.url = 'login_ajax.php';
// Perform the request:
$.ajax(options);
1) is this line options.success = function(response) suppose to return a boolean value?
2) also on the same line, options.success = function(response), i am having huge problem understanding where response came from. This parameter variable is not declared anywhere or passed in, so where did it come from?
3)
options.data = data;
options.dataType = 'text';
options.type = 'get';
......
options.url = 'login_ajax.php';
are these names, (data, dataType, type, and url) always required for ajax? or can this (or ajax in general) be done in different ways?
4) $.ajax(options);
can you explain this more?
thanks in advance guys!
