jQuery图像预加载程序

Posted 2021-02-25

Very easy way to preload images which are needed later (e.g. when a hover is performed)

<script type="text/javascript">
$.preloadImages = function()
{
       for(var i = 0; i<arguments.length; i++)
       {
               $("<img />").attr("src", arguments[i]);
       }
}
 
$(document).ready(function()
{
       $.preloadImages("hoverimage1.jpg","hoverimage2.jpg");
});
</script>
