JS 处理后台传过来的接送数据的 去重和查找方法

 1 //数组去重的算法 JS
 2 Array.prototype.uniqueByFiled = function(filed) {
 3     var res = [this[0]];
 4     for(var i = 1; i < this.length; i++) {
 5         var repeat = false;
 6         for(var j = 0; j < res.length; j++) {
 7             if(this[i][filed] == res[j][filed]) {
 8                 repeat = true;
 9                 break;
10             }
11         }
12         if(!repeat) {
13             res.push(this[i]);
14         }
15     }
16     return res;
17 };

1 $.post("HlsView",{choice:‘time‘,url_name:"",rtsp:"",ZSflg:""}, function(data) {
2     
3 var Area=data.uniqueByFiled("Area");
4 //此处假设我们对地区去重

5 
6 }, "json");

 1 //查询
 2 Array.prototype.Where = function(filed, filedValue) {
 3     var res = []
 4     for(var i = 0; i < this.length; i++) {
 5         if(this[i][filed] === filedValue) {
 6             res.push(this[i]);
 7         }
 8     }
 9     return res;
10 };
