local-storage

问题 Overview - I've added some code to copy an existing database to the device's local folder. So far the first condition if the existing db doesn't already exist works fine.

问题 I have created local DB (WebSQL) in HTML5. The content of the local storage has to be sent as an attachment in an email. The email client will be opened using javascript mailto feature.

I've taken the code below, and opened up multiple tabs of it. Using my Chrome Dev Tools, I can check >localStorage in the

问题 I'm looking to work around some performance issues on a mobile site by storing the data entered on multiple forms into the local Storage. I will be clearing the data on load and clearing the data on the last page, so no sensitive data will be left on the device after they visit the website on their mobile device. I do have a couple of concerns though: Can another program access the data I store in local storage? If the user doesn't complete the process can I place a expiration date on the
