加载多张图片，判断加载完成状态

var totalimages = 10; 
var loadedimages = 0;$(‘<img/>‘).load(function() {
++loadedimages; 
if(loadedimages == totalimages)
{
//全部图片加载完成时….. 
} });

(function(){
    $.fn.imgLoad = function(options){
        var opts = $.extend({
            time:4000, ///等待载入时间，如果超过这个时间就直接执行回调
            callback:function(){} //默认回调
        }, options);
        var $this = this,i = 0, j = 0, len = this.length;
        $this.each(function(){
            var _this = this,
                dateSrc = $(_this).attr("date-src"),
                imgsrc = dateSrc?dateSrc:_this.src;
            var img = new Image();
            img.onload = function(){
                img.onload = null;
                _this.src = imgsrc;
                i++;
            };
            img.src = imgsrc;
        });
        var t = window.setInterval(function(){
            j++;
            $("#msg").html(i);
            if (i==len || j*200>=opts.time){
                window.clearInterval(t);
                opts.callback();
            };
        },200);
    }

})(jQuery);

$(function(){
    $("img").imgLoad({
        time:10000000,//设置足够大 须等待图片载入完成，但是404的时候就杯具了...
        callback:function(){
            alert("载入完成")    
        }
    });
