For most offline browsing software (such as: Webzip, Offline Explorer), they could only grab the web by the source code which html file offers. Once they face JavaScript, they will doomed.
Offline Explorer Meet Errors When Dumping HTML5 Sites
And today, a fast increasing number of HTML5 websites which supported by new JavaScript technologies would definitely breakdown the offline browsing software, since hardly any of them could read JavaScript, just like the search engines.
From time to time, I use Offline Explorer to grab the website I like and storage them locally.
The offline browsing software need to be improved to solve this or maybe later this cake would be lost. But, the challenge is, everybody write different codes. These software could absolutely not recognize all codes, so maybe it’s time to say goodbye to this kind of software.
What’s the substitution? HTML5 Local Storage might be the one. Since HTML5 is based and explained by the browser itself. And Local Storage could save a lot data in it. So there’s no need to decode JavaScript but just run them once and see what the results are, and keep them in reserve.
