对象变量，用于在页面刷新后保留会话和cookie以外的值

Question

Was wondering whether there are other ways of retaining an object variable after page refresh besides using session and cookie. Tried window.name but the value become undefined after page refresh. The localStorage is good but too bad it only store in string value instead of object value.

Answer 1

You could serialise the object and store in localStorage . Then when you want to use it again, you unserialise it. Here's an example:

var myObject = {
   "Hello": "World",
   "Foo": "Bar"
}

localStorage.setItem("myObject", JSON.stringify(myObject));

Then later on, you can retrieve the object from localStorage :

var myObject = JSON.parse(localStorage.getItem("myObject"));

Answer 2

Found a workaround by using localStorage with JSON.stringify(object) .
