This article mainly introduces the relevant knowledge of HTML5 local storage development considerations, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this article on the development of HTML5 local storage. Let's take a look.

Note:

1. Debug sessionStorage and localStorage by using Webkit browser as far as possible, because their own debuggers have resource management options, so you can see not only these two local data, but also WebSql, cookie, etc., which is more intuitive and reliable.

It will be troublesome to use Firefox. Firebug local data can only be found in DOM using firebug, or install the Html5 localStorage Explorer plug-in. There is no need to think about IE, because several versions of IE9 do not support Html5.

2. When debugging sessionStorage, closing the window will invalidate the sessionStorage. It is impossible to open a window to store the sessionStorage and then read the sessionStorage in the new window.

3, when debugging localStorage, close the window localStorage will not fail, first open a window to store localStorage, and then read localStorage in a new window can be successful, and you can set up a listener to catch the value of key changes.

4. After storing the localStorage, refreshing the resource manager that comes with the webkit debugging tool cannot see the key and value, so you need to actively read it with a script to preview the local data.

5. Although Webkit's own debugging tool can directly see the WebSql database, it is best not to click when there is too much data, because it will jam the browser directly, so when there is a lot of data, it is better to open the database with SQlite tool.

6. The value values of sessionStorage and localStorage only accept strings and data. If you want to store more information, you can use JSON strings, which requires the json2.js tool, which can be downloaded from the official website of json.
