Ajax-something ------some thoughts and samples about Ajax Here provide some ideas I understand and some samples by applying these understandings. I build the environment by MAMP, Charles in mac system, and compile the prog in sublime and webstorm. Firstly, some basic knowledge about here, including PHP, and Ajax. Here we assume that the server database are exist and can be XML and json. Then I capsulate a tool function to sim the jQuery ajax method, and compare it with the true jQuery ajax method as well. At last, two more contents are introduced, the Template and Cross-domain. Upon thoughts all contain the relative samples.
