基于C的ajax功能实现源代码.docVIP

这是本人在学校时照老师的要求做的最简单的ajax功能，不好勿喷。这代码主要分为html代码和cs后台代码，和数据库连接的功能我就没发数据库了，都是简单的数据库。（基于C# 的ajax功能实现代码。），仅供参考。 1、地区信息查询 html xmlns=/1999/xhtml head title/title script type=text/javascript language=javascript var XMLHttpRequest; var requestType = ; function getXMLHttpRequest() { if (window.ActiveXObject) { XMLHttpRequest = new ActiveXObject(Microsoft.XMLHTTP); } else if (window.XMLHttpRequest) { XMLHttpRequest = new XMLHttpRequest(); } } function sendRquest(request) { requestType = request; getXMLHttpRequest(); XMLHttpRequest.onreadystatechange = stateChange; XMLHttpRequest.open(GET, XMLFile2.xml); XMLHttpRequest.send(null); } function stateChange() { if (XMLHttpRequest.readyState == 4) { if (XMLHttpRequest.status == 200) { if (requestType == north) { listNorthStates(); } else if (requestType == all) { listAllStates(); } else if (requestType == south) { listSouthStates();} else if (requestType == east) { listEastStates(); } else if (requestType == west) { listWestStates(); } } } } var northStates; var southStates; var eastStates; var westStates; var allStates; function listNorthStates() { var xmlDOC = XMLHttpRequest.responseXML; var northNode = xmlDOC.getElementsByTagName(north)[0]; northStates = northNode.getElementsByTagName(state); output(北à?à部?州Y名?, northStates); } function listSouthStates() { var xmlDOC = XMLHttpRequest.responseXML; var southNode = xmlDOC.getElementsByTagName(south)[0]; southStates = southNode.getElementsByTagName(state); output(南?部?州Y名?, southStates); } function listEastStates() { var xmlDOC = XMLHttpRequest.responseXML;
