Is there a way to programmatically build a JSON string? The desired outcome should resemble the following:
var myParamsJson = {first_name: "Bob", last_name: "Smith" };
Instead of constructing the entire object at once, I would prefer adding parameters one by one. For arrays, I typically go about it like this:
var myParamsArray = [];
myParamsArray["first_name"] = "Bob";
myParamsArray["last_name"] = "Smith";
I'm open to even creating an array first and then converting it into JSON format.
If you wanted to accomplish something similar using objects:
let myObject = {};
myObject["first_name"] = "Alice";
myObject["last_name"] = "Johnson";
Then, you could utilize the JSON.stringify function to convert that object into a JSON string.
let jsonString = JSON.stringify(myObject);
alert(jsonString);
This output will display:
{"first_name":"Alice","last_name":"Johnson"}
Most modern browsers come equipped with this JSON method (even though IE8 is an exception). In case you want to support older browsers, consider adding the json2.js script.
To create a basic object:
var person = {
first_name: 'Alice',
last_name: 'Smith'
};
Next, you can convert it into a string using JSON.stringify:
var jsonString = JSON.stringify(person); //"{"first_name":"Alice","last_name":"Smith"}"
