Save a json in a javascript array
提问by Gabriel Butoeru
I'm trying to save a json in a javascript array but I don't understand how to do it. I don't want to save all the content in the first element of the array. That's my function:
我正在尝试将 json 保存在 javascript 数组中，但我不明白该怎么做。我不想将所有内容保存在数组的第一个元素中。这就是我的功能：
function jeyson()
{
var onion = new XMLHttpRequest();
onion.open("GET", "json.json", true);
onion.send(null);
/* var anotheronion = angular.fromJson(onion.responseText, false); */
var onionarray = new Array()
}
onionarray is the array that I'd like to contain my json file.
onionarray 是我想要包含我的 json 文件的数组。
My json could be something like:
我的 json 可能是这样的：
{
"count": 2,
"e": 1,
"k": null,
"privateresult": 0,
"q": "surname",
"start": 0,
"cards": [
{
"__guid__": "efd192abc3063737b05a09a311df0ea0",
"company": false,
"__title__": "name1 surname",
"__class__": "entity",
"services": false,
"__own__": false,
"vanity_urls": [
"name1"
]
},
{
"__guid__": "01917cfa71a23df0a67a4a122835aba8",
"photo": {
"__own__": false,
"__title__": null,
"__class__": "image",
"__guid__": "01917cfa71a23df04d03f83cb08c11e1"
},
"company": false,
"__title__": "name2 surname",
"__class__": "entity",
"services": false,
"__own__": false,
"vanity_urls": [
"name2"
]
}
]
}
How can I save it in my array?
如何将它保存在我的数组中？
PS I don't have problems like "same origin policy" because the json file is on the same server (for now I'm working with local files. Could I work with files that are not on the same domain?).
PS 我没有像“同源策略”这样的问题，因为 json 文件在同一台服务器上（现在我正在处理本地文件。我可以处理不在同一域中的文件吗？）。
PSIs it possible to use json as a javascript object (like an array)? If I want to search something in my json object how can I do it?
PS是否可以将json用作javascript对象（如数组）？如果我想在我的 json 对象中搜索一些东西，我该怎么做？
function geisson()
{
var iabile = new XMLHttpRequest();
iabile.open("GET", "json.json", true);
iabile.send(null);
var objectjson = {};
objectson = JSON.parse(iabile.responseText);
alert(objectson.cards.toSource());
return false;
}

use the browser methods JSON.parse()and JSON.stringify()to convert your json to a javascript object and back.
使用浏览器的方法JSON.parse()和JSON.stringify()你的JSON转换为JavaScript对象和背部。
In your case, onionarrayshould not be an array but rather an object (In fact arrays and objects are >pretty< similar in javascript). You can assign your jsondata like that:
在你的情况下，onionarray不应该是一个数组，而是一个对象（实际上数组和对象在 javascript 中 >pretty< 类似）。您可以像这样分配 jsondata：
onionarray = JSON.parse(data);

Your incoming JSON is not an array; it is a JSON structure (in Javascript, the same as an object). So it can not be directly stored as an array.
您传入的 JSON 不是数组；它是一个 JSON 结构（在 Javascript 中，与对象相同）。所以不能直接存储为数组。
The json does include an array as the cardselement. -- Do want that?
json 确实包含一个数组作为cards元素。——要吗？
You need to
你需要
- Parse the incoming JSON into a JS structure. (Use JSON.parse.)
Once you have the structure in Javascript:
incoming = JSON.parse(data); onionarray = incoming.cards;
- 将传入的 JSON 解析为 JS 结构。（使用 JSON.parse。）
在 Javascript 中获得结构后：
incoming = JSON.parse(data); onionarray = incoming.cards;
Also note that the modern way to declare an empty array is
另请注意，声明空数组的现代方法是
var onionarray = [];
// not
var onionarray = new Array()
