每次刷新时JSON数据都会更改 [英] JSON data changes on every refresh

问题描述

我收到了一个Ajax调用，该调用从json文件中获取数据.之后，我计算对象的长度并仅获取长度.一切正常.但是在刷新时，它不会以相同的顺序显示数据

I got an ajax call which fetches data from a json file. After which i calculate the length of the object and get only the length. Everything is working fine. But on refresh its not displaying the data in the same order

//url i get from another file.which is a object hardcoded.
var initialsource = [{ "data": [] }];
var totallength = url.length;
var j = 0; // dummy variable to check whether the data has reached full length;

$.each(url,function(keys,values){   
    console.log(keys);  // get the keys which is mapped to json file location.// 1st console.
    $.get(values, function(jsondata) { // ajax call made to get the data
        console.log(keys); // 2nd console.
        initialsource[0].data.push({ 
            "datasource": keys,
            "values": jsondata[0].xxx.length
        })           
        j++;
        if (j == totallength) {
            //render data to html
        }
    })    
})

首次刷新

控制台1输出

Data-1:value-1
Data-2:value-2
Data-3:value-3
Data-4:value-4

控制台2输出

Data-1:value-1
Data-2:value-2
Data-3:value-3
Data-4:value-4

第二次刷新

控制台1输出

Data-1:value-1
Data-2:value-2
Data-3:value-3
Data-4:value-4

console-2输出//此处正在发生更改

console-2 output //changes are happening here

Data-2:value-2
Data-1:value-1
Data-3:value-3
Data-4:value-4

在每次刷新时，我都会更改数据顺序.这也反映在我的html中.如果有人可以帮助

And on every refresh i get the data order changed. Which is reflected in my html too. If someone could hel

推荐答案

为什么不使用jQuery根据键对数据进行排序并执行所需的操作.我有自定义排序的粘贴代码，希望对您有用.

why you don't sort data based on key using jQuery and do operation what you want to do. i have paste code of custom sort please hope do needful for you.

jQuery.fn.sort = function() {  
    return this.pushStack( [].sort.apply( this, arguments ), []);  
};  

 function sortLastName(a,b){  
     if (a.l_name == b.l_name){
       return 0;
     }
     return a.l_name> b.l_name ? 1 : -1;  
 };  
  function sortLastNameDesc(a,b){  
     return sortLastName(a,b) * -1;  
 };
var people= [
{
"f_name": "john",
"l_name": "doe",
"sequence": "0",
"title" : "president",
"url" : "google.com",
"color" : "333333",
}]

sorted=$(people).sort(sortLastNameDesc);
