How to store JSON data in sessionstorage

In web development, sessionstorage may often be used to store data and store single string data It is not difficult to use variables

var str = 'This is a string';
sessionstorage.setItem('param',str);

Get sessionstorage

var item = sessionstorage.getItem('param');
console.log(item);

But sessionStorage can only store string type data and cannot directly store array types and JSON objects. What should I do if there is a need? It's actually very simple.

First convert the JSON object into a string through the JSON.stringify() method, and then store it in sessionstorage

var obj = {"name": "Tom","age": 12,"gender": "man"};
sessionstorage.setItem('jsonParams',JSON.stringify(obj));

Then convert the string into a string through the JSON.parse() method JSON format is enough

var data = JSON.parse(sessionstorage.getItem('jsonParams'));
console.log(data);
