一个面向对象的ajax通用脚本(封装好的可当框架来用)

function tool() { var xmlHttp;//xmlHttpRequest object var urls;//submit url var xmlDOC; this.processMethod;//do method //create XMLHttpRequest object this.createXMLHttpRequest = function () { if (window.ActiveXObject) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } else { if (window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); } } return xmlHttp; }; //GET method submit do this.startProcessGet = function () { xmlHttp.open("GET", urls, true); xmlHttp.onreadystatechange = handleStateChange; xmlHttp.send(null); }; //opinion state function handleStateChange() { if (xmlHttp.readyState == 4) { if (xmlHttp.status == 200) { this.processMethod.call(null); } } } //setURL this.setURL = function (url) { urls = url; }; //set response.s method this.setProcessMethod = function (method) { processMethod = method; }; //get XMLHttpRequest object this.getXMLHttpRequest = function () { return xmlHttp; }; //get XMLDoc object this.getXMLDOC = function () { return xmlDOC; }; }
