如何解析包含字符串和数字的 JSON 文件，并将每个类别分配给 JS 中的变量？

Question

I'm trying to get my JSON file content into a JS variable, so I can start using what was in the JSON file. I'm having trouble figuring out how to parse each category and assigning them to a variable in JS.

So on the JS side, I would like for it to be somthing like this:

var 1 = jeff
var 2 = Internal

and so on...

Answer 1

Use JSON.parse() . I'm assuming the JSON is in a file. Also assuming var 1 = ... means first var one = ...

var jsonObject = JSON.parse(file);
var one = jsonObject.invites[someIndex].sender_id; // "jeff"
var two = jsonObject.invites[someIndex].vector; // "Internal"

Answer 2

You can use the following code to create global variables by the same name as json object properties.

data = {
    "invite_id": 1,
    "sender_id": "jeff",
    "sig_id": 25121,
    "invite": "The Owner has invited you",
    "vector": "Internal",
    "invite_time": 1398892261,
    "status": 'read'
}


//Iterate the object
for (var property in data) {
    if (data.hasOwnProperty(property)) {
        window[property] = data[property]  //create global variables by property name
    }
}

console.log(vector); //outputs 'Internal'

But the correct pattern is to create your variables within a private scope object. You can do it by replacing window with your private scope object.
