将JSON对象成员字符串值连接在一起 [英] Join JSON Object member string values together

问题描述

"category": [{
      "id": 28,
      "name": "Dogs"
  },
  {
      "id": 14,
      "name": "Cats"
  },
  {
      "id": 878,
      "name": "Sheep"
  }],

我已经解析了上面的JSON(使用.ajax和jsonp作为回调)，并且我想将"name"的所有值连接到一个字符串中.即狗，猫，羊".我怎样才能做到这一点?我已经尝试过对类别"和名称(即

I have the above JSON parsed (using .ajax and jsonp as callback) and I would like to join all the values of "name" into a string. i.e. "Dogs, Cats, Sheep". How can I do this? I have tried simple join on "category" and name, i.e.

var cats = categories.join(", ");

OR

var cats = categories.name.join(", ");

但是由于我们正在查看它的成员及其字符串值，所以它不起作用.

But since we are looking at it's members and their string values, it doesn't work.

推荐答案

这看起来像是$.map的工作！

var data = {
    "category": [{
          "id": 28,
          "name": "Dogs"
      },
      {
          "id": 14,
          "name": "Cats"
      },
      {
          "id": 878,
          "name": "Sheep"
      }]
}

var cats = $.map(data.category, function(v){
    return v.name;
}).join(', ');
