后台向前台传入json数据后解析问题

[BUG之家]

Map <Goods,List<Img>>goodsMap=goodsService.getAllImgBygoodsId(Integer.parseInt(goods_id));	
			PrintWriter out =response.getWriter();
			out.print(JSON.toJSONString(goodsMap));

success :function(data){
				alert(data);
				$(".cd-quick-view").empty();
				var returnData = eval(data);
				$.each(returnData,function(index,value){		
					    var $link1 =$("<div class='cd-slider-wrapper'></div>");		
					    var $link2 =$("<ul class='cd-slider'></ul>");
					    $link1.append($link2);					   
					    $.each(value.value,function(index,value){
					    	var $link3 =$("<li class='selected'></li>");
					    	var $imglist=$("<img />");
					    	$imglist.attr('src',value.key.img_name);
					    	$link3.append($imglist);
					    	 $link2.append($link3);
					    })
					    var $link4 =$("<ul class='cd-slider-navigation'><li><a class=’cd-next‘ href=’#0‘>Prev</a></li><li><a class=’cd-prev‘ href=’#0‘>Next</a></li></ul>");

						$link8.attr('href','#0');
						$link8.addClass("cd-close");
						$link8.html('Close');

						$(".cd-quick-view").append($link3);
						$(".cd-quick-view").append($link4);

				})
			},

这是我一次
{{"collect_count":30,"comment_count":200,"goods_name":"2","goods_price":"20","id":2,"sale_count":40,"stype_id":1}:[{"goods_id":2,"id":2,"img_name":"banma.jpg"},{"goods_id":2,"id":8,"img_name":"banma.jpg"}]}

[jio可]

你后台返回格式这样就很好解析了，ajax里面用handleAs:"json"返回的就直接是json了,不需要转json

{
    "baseInfo": {
        "collect_count": 30,
        "comment_count": 200,
        "goods_name": "2",
        "goods_price": "20",
        "id": 2,
        "sale_count": 40,
        "stype_id": 1
    },
    "data": [
        {
            "goods_id": 2,
            "id": 2,
            "img_name": "banma.jpg"
        },
        {
            "goods_id": 2,
            "id": 8,
            "img_name": "banma.jpg"
        }
    ]
}

alert(data);输出的是贴出来的内容？这个不是json字符串，eval后报错 java不懂，应该是你拿Goods当键使用的问题，导致Goods作为键名称了。。改为普通的字符串作为键名称，否则就需要用代码处理了

    var data = '{{"collect_count":30,"comment_count":200,"goods_name":"2","goods_price":"20","id":2,"sale_count":40,"stype_id":1}:[{"goods_id":2,"id":2,"img_name":"banma.jpg"},{"goods_id":2,"id":8,"img_name":"banma.jpg"}]}';
    var key = /\{\{([\s\S]+?)\}:\[\{/.exec(data)[1];
    var value=data.replace('{{'+key+'}:','').replace(/\}$/,'');
    key=eval('({'+key+'})');//Goods
    value=eval('('+value+')');//List<Img>
    console.log(key);
    console.log(value);
   //遍历Goods和value的代码
