IE8 and localStorage support [duplicate]

Answer 1

You can try to set and read localStorage.

Some browsers return a security error if cookies are disabled or you are working with file: protocol.

function hasStorage(){
    try{
        localStorage.setItem('test', '7');
        if(localStorage.getItem('test')=== '7'){
            localStorage.removeItem('test');
            return true;
        }
    }
    catch(er){}
    return false;
}

alert(hasStorage())
