我自己编写的AJAX请求函数

//根据URL获取文件名,可作为每页的唯一标识window.hbh.getUrlName=function(url){var wz1=url.lastIndexOf("/");var wz2=url.lastIndexOf(".");return url.substring(wz1+1,wz2);}//AJAX异步请求，将内容中的JS写在HEAD中，使JS内容生效，将剩下的HTML代码返回window.hbh.ajax=function(url,callback){var xmlhttp;if (window.XMLHttpRequest){xmlhttp=new XMLHttpRequest();}else{xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");}xmlhttp.onreadystatechange=function(){if (xmlhttp.readyState==4 && xmlhttp.status==200){var data=xmlhttp.responseText;var htmlCode=data.replace(/<script[^>]*>([\s\S]*?)<\/script>/mgi,"");callback(htmlCode);if(htmlCode!=data){var dialogId=hbh.getUrlName(url);if(!document.getElementById(dialogId+"Js")){var script=document.createElement("script");script.type='text/javascript';script.id=dialogId+"Js";script.text=data.replace(/[\s\S]*?<script[^>]*>([\s\S]*?)<\/script>[\s\S]*?/mgi,"$1");document.getElementsByTagName('head')[0].appendChild(script);}}}}xmlhttp.open("GET",url,true);xmlhttp.send(null);}
