1 We place a copy button on the page, it is mainly used to facilitate the user to copy a complex text links and the like, the conventional approach is to rely on Flash through JS, even by means of a huge jQuery js library to implement text copied to the clipboard.

3 This is a cool photo wall display of results, combined with a lot of photos fade, rotate, zoom, tilt and 3D effects, quick photo from the left to cut, do rotate the 3D effect, and finally lined up in the photo on the wall, in order to show users cool photo wall display effect.

5 As we all know, since the front end javascript to access cross-domain security restrictions made, javascript can only be accessed with the content of the document that contains it in the same domain. And when we encounter the actual code using iframe cross-domain access, Ajax cross-border communications and other operations, this time the problem of how to break cross-border operations, with examples of this article will tell solutions.

At the same how different subdomains main domain javascript calls? This problem easy to solve, such as the existing primary domain and subdomains helloweba.com abc.helloweba.com, there is a page in helloweba.com embedded iframe pointing to a certain page abc.helloweba.com under, iframe page needs access helloweba. com this js the function code of the page, then the solution is: at the top of the two pages plus document.domain information.
