数组去重

20170518更新

for (i = 0; i < obj4.length; i++) {
        for (j = 0; j < obj3.length; j++) {
            if (obj4[i].id == obj3[j].id) {
                obj3.splice(j, 1);
            }
        }
    }

用这种方法也是可以的，但是就是循环的次数会比continue的次数多

    f1:for(var i=0,leni=testList.length;i<leni;i++){
        for(var j=0;j<totalList.length;j++){
            if(totalList[j].id==testList[i].id){
                totalList.splice(j,1);
                j--;
                continue f1;
            }
        }
    }

    
    console.log(totalList);我写了好久，但是还是不太对，这个是诗瞻帮我写的
