Dynamic load, cache, update and reuse of JS (four)

Originally wanted to coherent, the loading process has been written, but the card is, so had to be divided into two.

1, the page use <script> to load boot.js.

2, then in boot.js dynamic loading bootload.js. With time as the identification of var datever = date.getyear () + "_" + date.getmonth () + "_" + date.getdate () + "_" + date.gethours (); This is guaranteed to be updated within an hour. At the same time also avoid every time to update.

3, Boot.js inside according to the situation to call the function provided in Bootload.js. The goal is to put the possible changes in the bootload.js to facilitate control of the update.

4, if it is the top page, then call the Bootload.js Nature.Top.topLoad (loads, kind); If the page is a subpage, call top.  Nature.Top.sonLoad (loads, kind,window); for subsequent processing.

5, Topload (), first get the latest version number, and then load Nature.LoadJs.js, the implementation of other JS file loading. If the JS file has an update, then get the latest version number will change, so you can realize the timely update of JS files .

6, Sonload () will load Nature.Adapter.js, to achieve reuse, is to make the child page can call the top page JS.

Simply put, that's it. There are a lot of details to be said in detail. At present the boot.js is basically stable. Bootload.js is about the same. Nature.LoadJs.js also need to change. It was too messy before.

Boot.js code.
