Let say I have the code as below:
<!DOCTYPE HTML>
<html>
<head>
<style>
#overlay_form{
position: absolute;
border: 5px solid gray;
padding: 10px;
background: white;
width: 270px;
height: 190px;
}
#pop{
display: block;
border: 1px solid gray;
width: 65px;
text-align: center;
padding: 6px;
border-radius: 5px;
text-decoration: none;
margin: 0 auto;
}
</style>
<script src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
//open popup
$("#pop").click(function(){
$("#overlay_form").fadeIn(1000);
positionPopup();
});
//close popup
$("#close").click(function(){
$("#overlay_form").fadeOut(500);
});
});
//position the popup at the center of the page
function positionPopup(){
if(!$("#overlay_form").is(':visible')){
return;
}
$("#overlay_form").css({
left: ($(window).width() - $('#overlay_form').width()) / 2,
top: ($(window).width() - $('#overlay_form').width()) / 7,
position:'absolute'
});
}
//maintain the popup at center of the page when browser resized
$(window).bind('resize',positionPopup);
</script>
</head>
<body>
<a href="#" id="pop" >PopUp</a>
<br />
<form id="overlay_form" style="display:none">
<h2> Put your contents here..</h2>
<label>Username: </label><input type="text" name="username" /><br /><br />
<label>Password: </label><input type="text" name="password" /><br /><br />
<input type="button" value="Login" />
<a href="#" id="close" >Close</a>
</form>
</body>
</html>
This is a popup dialog example. Let say I want to use this dialog in all my webpages (a.html, b.html, c.html and etc), what is the best and easiest way to make the code above to be reusable? Because I think that to copy paste the 'overlay_form' into every html pages is not reasonable.
I am still at the beginning level in Javascript, so to create a jQuery plugin for this is too hard for me. That's why I would like to seek for other ways to do it. Thanks.
