像这样的js，怎样绑定

Question

像这样的jquery轮切的图片，图片是固定，
<SCRIPT type=text/javascript>
    $("#slide").jdSlide({
        width: 766 ,
        height: 250,
        pics: [{
            src:
(screen.width >= 1200) ? "images/a1.jpg" : "images/a1.jpg",
            href: "http://www.baidu.com",
            alt: "",
            breviary: "#",
            type: "img"
        }, {
            src:
(screen.width >= 1200) ? "images/a2.jpg" : "images/a2.jpg",
            href: "#",
            alt: "",
            breviary: "#",
            type: "img"
        }, {
            src:
(screen.width >= 1200) ? "images/a3.jpg" : "images/a3.jpg",
            href: "#",
            alt: "",
            breviary: "#",
            type: "img"        }, {
            src:
(screen.width >= 1200) ? "images/a4.jpg" : "images/a4.jpg",
            href: "#",
            alt: "",
            breviary: "#",
            type: "img"
        }]
        })
</SCRIPT>
现在我改成AJAX的，
$(document).ready(function () {
    $.ajax({
        url: "Function/ChangePic.ashx",
        data: { "val": "index" },
        type: "get",
        datatype: "json",
        success: function (list) {            var dataobj = eval("(" + list + ")");
            var html = "[";
            var row = 0;
            $.each(dataobj.count, function (idx, item) {
                row = item.count;
            });
            $.each(dataobj.pics, function (idx, item) {
                html += "{src:\"" + item.src + "\",href:\"" + item.href + "\",alt:\"\",breviary: \"#\",type: \"img\"}";
                if (idx < (row - 1)) {
                    html += ",";
                }
            });
            html += "]";
            $("#slide").jdSlide({
                width: 766,
                height: 250,
                pics: html
            });
        }
    });
});就是没用，页面显示  一个src未定义，href未定义

Answer 1

确定json对象里有href和src这两个属性么？

Answer 2

结构中src接收参数是数组，所以你最好定义html就用var html＝［］，然后push对象，或者如果保持拼接字符串的话最后eval下。

Answer 3

each函数里面加上debugger看看item里面的属性值有无问题。
