How to Store JavaScript Objects in HTML5 localStorage
Topic: JavaScript / jQueryPrev|Next
Answer: Use the JSON.stringify() Method
By default, the localStorage or sessionStorage only allows you to store string key/value pairs. But you can also store the JavaScript objects in web storage with a little trick.
To store objects first stringify it using the JSON.stringify() method, and later parse it with the JSON.parse() when you need retrieve it, as shown in the following example:
Example
Try this code »<script>
var personObject = { name: "Peter", age: 18, married: false };
// Convert the person object into JSON string and save it into storage
localStorage.setItem("personObject", JSON.stringify(personObject));
// Retrieve the JSON string
var jsonString = localStorage.getItem("personObject");
// Parse the JSON string back to JS object
var retrievedObject = JSON.parse(jsonString);
console.log(retrievedObject);
// Accessing individual values
console.log(retrievedObject.name); // Prints: Peter
console.log(retrievedObject.age); // Prints: 18
console.log(retrievedObject.married); // Prints: false
</script>See the tutorial on HTML5 web storage to learn more about local and session storage.
