如何获取随机json数据并追加到div元素 [英] how to get random json data and append to div element

问题描述

说这是我的json

[
{
    "imageSmall": ["images/employee_jpgs/employees_abhishek_80x80.jpg"],
    "imageBig": ["images/employee_jpgs/employees_abhishek_150x150.jpg"],
    "name": ["Abhishek Shet"],
    "quotes": ["Just perfect to start your career after school. Makes me feel        others in the industry are way slower then us. Awesome team and and a brilliant product to work on!!!!. And most importantly I enjoy what I do :)."],
    "type": "employee"
},
{
    "imageSmall": ["images/employee_jpgs/employees_barbra_80x80.jpg"],
    "imageBig": ["images/employee_jpgs/employees_barbra_150x150.jpg"],
    "name": ["Barbra Gago"],
    "quotes": ["The best part about working at tibbr is how dynamic the environment is, there's a lot of flexibility and freedom to execute on new ideas. Because everyone is so talented, there is a ton of trust and support coming from managers and team members-we all count on each other to do the best possible job!"],
    "type": "employee"
},

同样继续，但是有3种类型 1名员工 2推特 3-社交

the same continues but there are 3 types 1-employee 2-twitter 3-social

现在我的问题是我想随机获取这些json数据并追加到我的div元素中 我使用了以下代码

Now my problem is I want get these json data randomly and append to my div element I used following code

function(args){
 var me=this;
 $.getJSON(args.json,function(data) { 
 me.set(args);
 $.each(data, function(i){
    var id="randomizr_item_" + i;
    var temp= $('<div id='+ id +' class="randomizr-grid-items"><img src="'+ this.imageSmall[0]  +'" /></div>');
    me.config.container.append(temp);
    this.target=$(temp);
});

我知道如何使用以下代码生成单个随机条目

I know how to generate single random entry using following code

entry = data[Math.floor(Math.random()*data.length)];

生成一个随机条目.

请帮助我如何从上面的json文件中随机获取json数据并追加到div.

Plz help me how to get json data randomly from above json file and append to div.

推荐答案

您需要制作一个随机的唯一数字数组，如下所示:

You need to make an array of random unique numbers like following:

function generateRandom(min, max) {
    var arr = [];
    while(arr.length < 5){
      var randNum = Math.floor(Math.random() * (max - min + 1)) + min,
          found=false;
      for(var i=0;i < arr.length; i++){
        if(arr[i] == randNum){found=true;break}
      }
      if(!found)arr[arr.length] = randNum;
    }
    return arr;
}

然后您需要遍历数据，如下所示:

Then you need to loop over data like following:

在这里，我遍历唯一数组，而不是在data上，并使用数组的值作为data的索引.

Here I am looping over unique array, not on data and using value of array as index to data.

var orders = generateRandom(0, data.length-1);

$.each(orders, function(index, value){
    var id="randomizr_item_" + i;
    var temp= $('<div id='+ id +' class="randomizr-grid-items"><img src="'+ data[value].imageSmall[0]  +'" /></div>');
    me.config.container.append(temp);
    this.target=$(temp);
});
