HTML离线数据存储

Question

Just wanted to know is there any way where we can store offline data/imagee(20MB+) in HTML which is supported IE 10 metro browser. I haver gone through below links

Building Offline storage

Appreciate you can give me a running sample which stores the data/images locally and retrieves later on. Note this should be supported on IE10 of Windows 8 metro(tablet PC).

Answer 1

There are several means of doing this:

• Using the appCache , you can store offline data using manifests, but are you are strictly limited in how much data you can store
• Using the indexedDB , you can store much more data, but it's up to you to read and write the data programatically.

using a combination of the two, you can use the appCache to store your HTML/JavaScript offline, and then, while offline, pull the 20+MB of image data out of the indexedDB.
