    可以用split来分解var a = '图片1|/UpFiles/Picture/200709/2007092011025798869.jpg|/UpFiles/Picture/200709/2007092011025798869.jpg|||图片2|/UpFiles/Picture/200709/2007092011025890976.jpg|/UpFiles/Picture/200709/2007092011025890976.jpg|||图片3|/UpFiles/Picture/200709/2007092011025875076.jpg|/UpFiles/Picture/200709/2007092011025875076.jpg|||图片4|/UpFiles/Picture/200709/2007092011025842569.jpg|/UpFiles/Picture/200709/2007092011025842569.jpg|||图片5|/UpFiles/Picture/200709/2007092011025866849.jpg|/UpFiles/Picture/200709/2007092011025866849.jpg';var arr = a.split("|||");
    for(var i=0; i<arr.length; i++){
        var imgs = arr[i].split("|");
        alert(imgs[0] + "=" + imgs[1]);
        //alert(imgs[0] + "=" + imgs.slice(1));
