🦑How to get the maximum storage size of localStorage ?

A brief introduction to localStorage, sessionStorage, cookies

1) localStorage: Only the client storage does not participate in server communication. The storage size is generally 5M. If it is not manually cleared, then it will always exist even if the browser is closed.

2) sessionStorage: Only the client storage does not participate in server communication, the storage size is generally 5M, session-level storage, which means that it will be cleared if the current page or browser is closed

3) cookie: client storage, participate in server communication, storage size is 4k, can set life cycle, effective within the set life cycle

function() {
if(!window.localStorage) {
console.log('-localStorage!')
}
var test = '0123456789';
var add = function(num) {
num += num;
if(num.length == 10240) {
test = num;
return;
}
add(num);
}
add(test);
var sum = test;
var show = setInterval(function(){
sum += test;
try {
window.localStorage.removeItem('test');
window.localStorage.setItem('test', sum);
console.log(sum.length / 1024 + 'KB');
} catch(e) {
alert(sum.length / 1024 + 'KB');
clearInterval(show);
}
}, 0.1)
})()

🦑Run the above method directly in the browser console.

The local storage in the Chrome browser is 5120kb, which is 5M.
