Well, first of all:
<div "> <--- Invalid Markup
<label>Password</label>
<input type="text" name="passwd" id="pas" class="fields"/>
</div>
<table width="800" border="0" cellpadding="1" cellspacing="0" /> <--- self closing Table......
your Email-regex is invalid.
And last: change:
$("#sign").click(function(e) {
})
to:
$("#submitbutton").click(function(e) {
});
and
<button type="submit" id="submitbutton" class="sinbutton">Sign Up</button>
to
<button id="submitbutton" class="sinbutton">Sign Up</button>
and
if (hasError == true) {
return false;
}
else {
//submit form via ajax
}
to
if (hasError == true) {
e.preventDefault();
}
else {
//submit form via ajax
}
UPDATE
Your regex is still invalid! Uncomment the regex, and the code that checks it to take it out of the equation for now.
you're declaring:
var days=$("#da").val();
but later on you're trying to access the variable "day" that doesn't exist.
same thing here: var years=$("#yea").val(); but accessing variable year:
if (month=='' || day=='' || year==''){
First: You need to learn how to use FireBug (Firefox), Developer Tools (IE) or the inspector in Chrome, because the javascript errors are displayed there.
Second: you should learn how to format your questions properly. I've had to edit your question twice now, cleaning it up.
Third: When posting questions regarding HTML/Javascript/CSS, you should use jsfiddle.net to demo your code. Take a look at this:
http://jsfiddle.net/yngvebn/FdunX/
because you have form an submit button when you click the button form is submitting. Change the code like that
$("#sign").click(function(e){
e.preventDefault();
