删除数组中键周围的双引号

Question

my array has keys with double-quotes "" around them, how can I remove them?

I'm generating my object from input fields like this:

var obj = {};
obj.Firstname = document.getElementById("firstName").value;
obj.Lastname = document.getElementById("surname").value;
var jsonStringObj = {
    users: [JSON.stringify(obj)]
};
console.log(jsonStringObj)

Result is like this:

users: ["{"Firstname":"","Lastname":""}"] <<-- wrong

Expected array:

users: [{Firstname:"john",Lastname:"doe"}] <<-- I want this

I have tried the following unsuccessful attempts:

var string = JSON.stringify(array);
string.replace (/"/g,'');

Answer 1

When you write JSON.stringify to convert it in the string, it would add the double quotes to your keys.

You just have to write obj directly, it would behave as the normal object and not string.

So please update your code of lines with the below code. It should resolve your problem.

var obj = {};
 obj.Firstname = document.getElementById("firstName").value;
 obj.Lastname = document.getElementById("surname").value;
 var jsonStringObj = {users: [obj]};
 console.log(jsonStringObj)

Answer 2

You can use JSON.parse(),this will change a json to object. here is the example:

var obj = JSON.parse(users)

if you want to change an object to string you use JSON.stringify(obj)

Answer 3

There is no need to stringify the object at all.

 var obj = {}; obj.Firstname = ""; obj.Lastname = ""; var obj2 = {users: [obj]}; console.log(obj2);
