调用方法比较简单

var http_request = getHttpRequest();if (!http_request) {alert('建议使用IE或Firefox浏览器!');} else {var linkurl = '/AjaxTest/ajax.jsp' + "?RecruitePerID=" + RecruitePerID+ "&TestPaperID=" + TestPaperID+ "&QuestionID=" + QuestionID+ "&QuestionAnswer=" + QuestionAnswer+ "&submitButtonFlag=" + submitButtonFlaghttp_request.open("GET", linkurl, false);http_request.send(null);var returntxt = unescape(http_request.responseText);}
