Fade in page background image on load with jQuery
I want to fade in a CSS page background image with jQuery when m开发者_运维技巧y page loads. I know it is possible to set a CSS page background image with jQuery and it is also possible to fade in text when a page loads but I am not sure how to do both.
You can set a CSS background image in jQuery by doing:
showBackground($("body").css({"background-image":"url(yourimage.jpg)"}));
You can fade in text by doing:
$(document).ready(function(){
$('#fade').hide();
$('#fade').append('This text should fade in.');
$('#fade').fadeIn();
});
You can load the body background image on page load but to fade it you need to use some other manipulation like putting a div
with 100% height-width to hold background image. I have tried following and it fades in both text and background (in div).
<html>
<head>
<script type="text/javascript"
src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js">
</script>
</head>
<body>
<div id="b" style="display:none;left:0;top:0;margin:0;padding:0;width:100%
!important; height:100% !important;
background-image:url('DSC00667.jpg');z-index:-1000;">
</div>
<div style="top:0;left:0;position:absolute;">
<div id="d" style="height:200px;width:500px;margin:0 auto;top:0;
clear:none;z-index:100;">
this is text div that will fade in.
</div>
<div style="clear:both;height:1px !important;"> </div>
</div>
<script type="text/javascript">
$(function(){
$("#b").fadeIn();
$('#d').hide().append('This text should fade in.').fadeIn();
});
</script>
</body>
</html>
fewer style elements may also work but I have not tested.
