jQuery图片加载显示loading效果
在很多时候我们需要用到图片加载功能,在网上搜资料后就想为了以后使用方便重新整理了下,结果如图:
最后一张是加载失败显示的图片,没找到合适的图片,先用他顶替。
页面引用
<div class="container"> <div class="row block" id="img-list"> <div class="col-md-3"> <img src="/Assets/OnePiece/1.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/2.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/3.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/4.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/5.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/6.jpeg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/7.jpg" class="img-thumbnail"> </div> <div class="col-md-3"> <img src="/Assets/OnePiece/8.jpg" class="img-thumbnail"> </div> </div> </div> <script src="~/Scripts/ImgLoading/ImgLoading.js"></script> <script> $("#img-list").ImgLoading({ errorimg: "/Scripts/ImgLoading/images/noimage.png", loadimg: "/Scripts/ImgLoading/images/load.gif", timeout: 800 }); </script>
下面是插件脚本,为了突出加载的效果就加上了延迟时间。
;(function ($) { $.fn.extend({ ImgLoading: function (options) { var defaults = { errorimg: "http://www.oyly.net/Images/default/Journey/journeydetail.png", loadimg: "http://www1.ytedu.cn/cnet/dynamic/presentation/net_23/images/loading.gif", Node: $(this).find("img"), timeout: 1000 }; var options = $.extend(defaults, options); var Browser = new Object(); var plus = { BrowserVerify:function(){ Browser.userAgent = window.navigator.userAgent.toLowerCase(); Browser.ie = /msie/.test(Browser.userAgent); Browser.Moz = /gecko/.test(Browser.userAgent); }, EachImg: function () { defaults.Node.each(function (i) { var img = defaults.Node.eq(i); plus.LoadEnd(Browser, img.attr("imgurl"), i, plus.LoadImg); }) }, LoadState:function(){ defaults.Node.each(function (i) { var img = defaults.Node.eq(i); var url = img.attr("src"); img.attr("imgurl", url); img.attr("src",defaults.loadimg); }) }, LoadEnd: function (Browser, url, imgindex, callback) { var val = url; var img = new Image(); if (Browser.ie) { img.onreadystatechange = function () { if (img.readyState == "complete" || img.readyState == "loaded") { callback(img, imgindex); } } } else if (Browser.Moz) { img.onload = function () { if (img.complete == true) { callback(img, imgindex); } } } img.onerror = function () { img.src = defaults.errorimg } img.src = val; }, LoadImg: function (obj, imgindex) { setTimeout(function () { defaults.Node.eq(imgindex).attr("src", obj.src); }, defaults.timeout); } } plus.LoadState(); plus.BrowserVerify(); plus.EachImg(); } }); })(jQuery);
脚本是从网上搜索代码之后整理的,也是第一次写插件,如果有啥写的不对的,还请多多指教!
