关于筛选json并生成新的json的问题。
有一json数据如下：

JScript code

var products = [{    id: "1001",    name: "a",    cate: "x"},{    id: "1002",    name: "b",    cate: "x"},{    id: "1003",    name: "c",    cate: "x"},{    id: "1004",    name: "c",    cate: "y"}];

如何用js筛选出所有cate=x的数据并生成性的json如下：

JScript code

var products = [{    id: "1001",    name: "a",    cate: "x"},{    id: "1002",    name: "b",    cate: "x"},{    id: "1003",    name: "c",    cate: "x"}];

[解决办法]

JScript code

    var products=[{id:"1001",name:"a",cate:"x"},{id:"1002",name:"b",cate:"x"},{id:"1003",name:"c",cate:"x"},{id:"1004",name:"c",cate:"y"}];    var arr = [];    for(var i = 0, len = products.length; i < len; i++){        if( products[i].cate == 'x' ){            arr.push(products[i])        }    }    alert(arr)
