Question

这种JSON数据怎么解析？？？？

[{"krnum":0,"kname":"娱乐","kid":1},{"krnum":0,"kname":"生活","kid":2},{"krnum":0,"kname":"财经","kid":3},{"krnum":0,"kname":"购物","kid":4},{"krnum":0,"kname":"科技","kid":5},{"krnum":0,"kname":"健康","kid":6},{"krnum":0,"kname":"旅游","kid":7},{"krnum":0,"kname":"体育","kid":8},{"krnum":0,"kname":"军事","kid":9},{"krnum":0,"kname":"文化","kid":10},{"krnum":0,"kname":"其他","kid":11}]

Answer 1

json就相当于js的数组和对象的结构，你这个最外层是中括号，所以是个数组，数组的每一项是大括号包围的，所以数组每个元素是一个js的对象结构
只要用for循环遍历数组，得到每个对象
js的对象是key:value格式的。所以用 对象.key 方式获取数据的

var list = [{"krnum":0,"kname":"娱乐","kid":1},{"krnum":0,"kname":"生活","kid":2},{"krnum":0,"kname":"财经","kid":3},{"krnum":0,"kname":"购物","kid":4},{"krnum":0,"kname":"科技","kid":5},{"krnum":0,"kname":"健康","kid":6},{"krnum":0,"kname":"旅游","kid":7},{"krnum":0,"kname":"体育","kid":8},{"krnum":0,"kname":"军事","kid":9},{"krnum":0,"kname":"文化","kid":10},{"krnum":0,"kname":"其他","kid":11}];
for(var i=0;i<list.length;i++)
{
var item = list[i];
alert(item.kname)//获取kname的值

}

Answer 2

<script language="javascript">
var data = eval('[{"krnum":0,"kname":"娱乐","kid":1},{"krnum":0,"kname":"生活","kid":2},{"krnum":0,"kname":"财经","kid":3},{"krnum":0,"kname":"购物","kid":4},{"krnum":0,"kname":"科技","kid":5},{"krnum":0,"kname":"健康","kid":6},{"krnum":0,"kname":"旅游","kid":7},{"krnum":0,"kname":"体育","kid":8},{"krnum":0,"kname":"军事","kid":9},{"krnum":0,"kname":"文化","kid":10},{"krnum":0,"kname":"其他","kid":11}]');

var View = [];
for(var i=0;i<data.length;i++)
{
View.push("ID:"+data[i].krnum+" ");
View.push("Name"+data[i].kname+" ");
View.push("Kid"+data[i].kid+"\n");
}
alert(View.join(""));
</script>

要把你的json代码发上来，这样提问都不知道怎么回答的
你要追问里提问，或者做问题的补充就可以
