jquery预加载显示百分比详解编程语言

jquery预加载显示百分比

 <img class="bj loadimg" loadimg="/weiqingshu/images/1/bj.jpg"/>

<script type=”text/javascript” src=”/caigeci/js/jquery.imgpreload.min.js”></script>

 imgNum=0;
 var load_img = [];
 /*$('.loadimg').each(function () {
 var loadimg=$(this).attr('loadimg');
 load_img.push(loadimg);
 })*/
 load_img.push( '/caigeci/images/answer0.jpg' );
 load_img.push( '/caigeci/images/answer1.jpg' );
 /*ss*/
 jQuery.imgpreload(load_img, {
 each: function () {
 /*this will be called after each image loaded*/
 var status = $(this).data('loaded') ? 'success' : 'error';
 if (status == "success") {
 var v = (parseFloat(++imgNum) / load_img.length).toFixed(2);
 console.log(Math.round(v * 100) + "<sup>%</sup>");
 }
 },
 all: function() {
 console.log('全部加载完成');
 /*$('.loadimg').each(function () {
 var loadimg=$(this).attr('loadimg');
 $(this).attr('src',loadimg);
 })*/
 }
 });

ps:加载的文件个数 /全部文件个数 的百分比就是进度
