哥哥写的例子（后台没有进行排序分组的时候，前台进行自己分组）

    //原始数据，后台没有进行排序的
var rowData=[
        {data:2,date:'01',code:'cr_2',name:'桥吊2'},
        {data:1,date:'03',code:'cr_1',name:'桥吊1'},
        {data:4,date:'06',code:'cr_1',name:'桥吊3'},
        {data:111,date:'09',code:'cr_1',name:'桥吊1'},
        {data:212,date:'02',code:'cr_2',name:'桥吊2'},
        {data:222,date:'03',code:'cr_2',name:'桥吊2'},
        {data:11,date:'07',code:'cr_1',name:'桥吊1'}
    ];
    //需要的数据
    var result1=[
        {name:"cr_1",data:[1,4,11,111]},
        {name:"cr_2",data:[2,212,222]}
    ];
    //=========================================================
    //1.数组添加元素
    var newAry = [];
    for(var i=0;i<rowData.length;i++){
        //1.判断数组中是否包含该元素，不包含则添加，包含则追加子元素
        var result = fun_IsExists(newAry,rowData[i].code);
        if(result.flag){
            newAry[result.index].data.push(rowData[i].data);
        }else{
            newAry.push({
                name:rowData[i].code,
                data:[rowData[i].data]
            });
        }
        newAry.push();
    }
    
    //debugger;
    //2.对象数组排序（将cr_1根据名字进行排序）
    newAry.sort(compare("name")); 
    //判断是否存在
    function fun_IsExists(newAry,name){
        var flag = false;
        var index = -1;
        for(var i=0;i<newAry.length;i++){
            if(newAry[i].name == name){
                index = i;
                flag = true;
                break;
            }
        }
        return {
            flag:flag,
            index:index
        };
    }
    //排序
    function compare(prop) {
       return function (obj1, obj2) {
            var val1 = obj1[prop];
            var val2 = obj2[prop];if (val1 < val2) {
                return -1;
            } else if (val1 > val2) {
                return 1;
            } else {
                return 0;
            }            
        }
    }
