问题 Is it possible to save the current state of a webpage so you can later restore it to that state? Through "state" I mean everything that defines the current behavior of the page: html tags, css, JavaScript variables, form data, etc... So you could simply have something like: savePage() which stores all the needed data in localhost and then use loadPage() to retrieve that data. I guess the html , css and inputs value are easy to save, but what about all the JavaScript variables on that page? Is

问题 I want to make a function that add an item to my localStorage object. E.g.: alert(localStorage.getItem('names').addItem('Bill').getItem('names')); The first method is getItem which gets the item for localStorage objects... but addItem would be a custom function.

问题 I'm wondering the advantage of the local memory in it. Since the global memory can get the item separately and freely. Can't we just use the global memory? For example, we have a 1000*1000 image, and we want add every pixel value 1. We can use 1000*1000's global memory right? Will it be faster for us if we use local memory and turn the 1000*1000 image into 100 100*100 parts? I'll be so appreciate for you, if you give me a simple code of the local memory. 回答1: Cann't we just use the global

问题 I am running an electron app, where in its renderer process I use HTML5 localStorage. I'm interested to know where in my file-system is this localStorage actually stored (I believe it is in SQLite format).

I'm asking this because I would like to be able to run 2 instances of this electron application, so that each application will have different settings in which I save in

But when I comment out line 2 (which sets the item value) and refresh the page it just alerts 'null'. Why is the value not persisting? It's like it's just not actually getting stored at all. The

Something like this? <input type='text' name="server" id="saveServer"/>
