Recently in the process of doing the project will always encounter the problem of data array, after several changes in the program are summarized as follows:

Data to go heavy

The code is as follows

var zdata = [];
Cityaname = Result.aname;
Isp_cityname = $ ('. Isp_cityname ' + monitorip_arr[num]). HTML ();
if (Zdata[cityaname]) {
Zdata[cityaname][zdata[cityaname].length] = {"Value": Result.totaltime, "name": Isp_cityname, "Stateinitcolor": "3"};
} else {
Zdata[cityaname] = [];
Zdata[cityaname][0] = {"Value": Result.totaltime, "name": Isp_cityname, "Stateinitcolor": "5"};

PHP can also use this idea, and PHP is much simpler than JS ...

Array to weight

code as follows  

//second method
Array.prototype.distinct=function () {
var Newarr=this.concat (). Sort (), self=this;
Newarr.sort (function (a,b) {
var n;
if (a===b) {
N=self.indexof (a);
Self.splice (n,1);
return self;
Console.log ([1,2,2,3, ' 5 ', 6,5,6,6,15,5, ' 5 ', 5, ', ', '].distinct ());
