使用javascript

Question

我在Kimonolabs中有Json输出文件看起来像这样

{
"name": "text",
"results": {
"collection1": [
  {
    "title": {
      "href": "link",
      "text": "text"
    },
    "description": "text",
    "author": "text",
    "index": 1,
    "url": "link"
  },etc.
}]}}

我想添加一个变量＆＃39;类别＆＃39;到collection1数组中的变量，并使该类别的值为＆＃39; food＆＃39;对于每个数组项。但是为了让它发挥作用，整天苦苦挣扎。有什么建议吗？

我尝试的是：

function transform (data){

//create shortcut for collection variable
var collection = data.results.collection1;

//function to add category
function addcat(line){
line[category] ='food';
return row;
}

//loop through variables;
for (var i=0; i < collection.length; i++){
[collection] = [collection].map(addcat);

return data;
}

Answer 1

for (var i = 0; i < object.results.collection1.length; i++) {
    object.results.collection1[i].category = 'food';
};
