ajaxpostxml

var XMLHttpReq = false;
//   创建   XMLHttpRequest   对象(主函数不需改变)  
function createXMLHttpRequest(){
    if (window.XMLHttpRequest) { //   Mozilla   浏览器  
        XMLHttpReq = new XMLHttpRequest();
    }
    else
        if (window.ActiveXObject) { //   IE   浏览器  
            try {
                XMLHttpReq = new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch (e) {
                try {
                    XMLHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
                }
                catch (e) {
                }
            }
        }
}

//第一步:创建一个XML的DOM对象,可用如下方法完成

function CreateDomDoc() //创建XML文档对象
{
    var signatures = ["Msxml2.DOMDocument.5.0", "Msxml2.DOMDocument.4.0", "Msxml2.DOMDocument.3.0", "Msxml2.DOMDocument", "Microsoft.XmlDom"];
    for (var i = 0; i < signatures.length; i++) {
        try {
            var domDoc = new ActiveXObject(signatures[i]);
            return domDoc;
        }
        catch (e) {
        }
    }
    return null;
}

//第二步:从客户端取得数据写入XML,方法如下:
function CreateXml(doc){
    var root = doc.createElement("root");
    var title = doc.createElement("title");
    title.text = document.getElementByIdx("tbTitle").value;
    root.appendChild(title);
   
    var ToGrade = doc.createElement("ToGrade");
    ToGrade.text = document.getElementByIdx("ddlToGrade").options[document.getElementByIdx("ddlToGrade").selectedIndex].value;
    root.appendChild(ToGrade);
   
    var cOntent= doc.createElement("content");
    content.text = getEditorContents();
    root.appendChild(content);
   
    var BreviaryPic = doc.createElement("BreviaryPic");
    BreviaryPic.text = document.getElementByIdx("BreviaryPicUrl").value;
    root.appendChild(BreviaryPic);
   
    var classID = doc.createElement("classID");
    classID.text = chkCheckBoxChs("articleClass");
    root.appendChild(classID);
   
   
    //alert(classID.text);
   
    doc.appendChild(root);
    //alert(doc.xml);
    return doc.xml;
   
}

//第三步 互相调用

//第四步 AJAX发送
function sendRequest(url, domDoc){
    createXMLHttpRequest();
    XMLHttpReq.Onreadystatechange= processResponse;
    XMLHttpReq.open("POST", url, false);
    XMLHttpReq.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;"); //关键,否则出错
    XMLHttpReq.send(domDoc); //发送一定是domDoc文档对象,如果只发送xml将出错”statue=500”
}

//处理返回信息函数(处理xml格式的返回信息)
function processResponse(){
    if (XMLHttpReq.readyState == 4) {
        if (XMLHttpReq.status == 200) {
            info = XMLHttpReq.responseText;
            //alert(info);
            if (info == "1") {
                ShowMsgo.show(msgTitle,msgContentSuccess, 2)
            }
   else{
    ShowMsgo.show(msgTitle,msgContentFaild, 2)
   }
        }
        else {
            //alert("ajax调用失败！" + XMLHttpReq.status);
   ShowMsgo.show(msgTitle,msgContentFaild, 2)
        }
    }
   
}

//建立doc
function CreateDomXml(){
    var domDoc = CreateDomDoc(); //创建对象 将用send发送到服务器端
    if (domDoc != null) {
        var xml = CreateXml(domDoc); //写入xml 返回xml文档
        //alert(domDoc);//
        return domDoc;
    }
    else {
        alert("未安装MSXML控件");
    }
}

//页面执行方法
function sendto(){
    if (document.form1.tbTitle.value == "") {
        alert("请填写文章标题");
        document.form1.tbTitle.focus();
        return false;
    }
    else
        if (getEditorContents() == "") {
            alert("请填写文章内容");
            return false;
        }
        else
            if (chkCheckBoxChs("articleClass") == "") {
                alert("请选择文章发布类别");
                return false;
            }
            else {
                var url = "ajaxArticleAdd.aspx";
                var doc = CreateDomXml();
                //alert(doc.xml);
                sendRequest(url, doc)
            }
}

 

//多选框选值
function chkCheckBoxChs(objNam){ //获得多选框连续值
    var obj = document.getElementsByName(objNam); //?取多?框?到M
    var objLen = obj.length; //?取???L度
    var objYN; //多选框选择的值  0为未选  1为选择   "|"分隔符
    var i;
    var result = "";
   
    for (i = 0; i         if (obj[i].checked == true) {
            objYN = obj[i].value;
           
        }
        else {
            objYN = "";
        }
        //result+=objYN;
        if (objYN != "") {
            if (i == (objLen - 1)) {
                result = result + objYN;
            }
            else {
                result = result + objYN + ",";
            }
        }
    }
    return result;
