load a page after event.preventDefault()

October 23, 2013

preventDefault is used to disable the default action of an event. like cut copy paste submit clicking a link, if preventDefault is declared, the event attached wouldn’t work.

$("form[name='nameForm']").submit(function(event){
	event.preventDefault();
	funcName();
});

after declaring the selector of the form, the submit handler is then declared and a function with an event as a parameter. this event is then used to determine which event to disable. in this case the, preventing the submit button to automatically reload. the next line after that, is the function

function funcName() {
	$.get("http://SomeSite.html/session.php", {email: email_submit})
		.done(function() {
			window.location.href = "http://SomeSite.html";
	});
}

The $.get in JQuery would then first make a pit stop to start a session. after everything is done, the XMLHTTPRequest object returned from the $.get will have a chain .done() attached. this allows us to load after the process in the .get is finished. I didn’t do this the first time and just put the window.location.href after the .get() statement, in which would result for the page to load even if the .get() is not done yet.
