Add AJAX-related JS methods, most of which are based on prototype (a good JavaScript Framework) class library.
1. Loadajaxelement,loadajaxdata,sendajaxelement,sendajaxdata these four methods are true to connect the Ajax operation method;
2. Parsexml,importxml,gettextnodevalue these three methods are the processing of XML data in the Ajax return results, which can be handled by parsexml if the results are not standard XML documents. Generate XmlDocument objects;
The 3.getParams method is used to return the URL parameter value of the current page;
4.showloading,hideloading These two methods are used to show the information during the page loading process;
