JS讀取XML文件（兼容瀏覽器）

1、通過JS讀取XML文件，主要是判斷各個瀏覽器

// 加載xml文檔
       var loadXML = function (xmlFile) {
            var xmlDoc;
            if (window.ActiveXObject) {
                xmlDoc = new ActiveXObject('Microsoft.XMLDOM');//IE瀏覽器
                xmlDoc.async = false;
                xmlDoc.load(xmlFile);
            }
            else if (isFirefox=navigator.userAgent.indexOf("Firefox")>0) { //火狐瀏覽器
            //else if (document.implementation && document.implementation.createDocument) {//這里主要是對谷歌瀏覽器進行處理
                xmlDoc = document.implementation.createDocument('', '', null);
                xmlDoc.load(xmlFile);
            }
            else{ //谷歌瀏覽器
              var xmlhttp = new window.XMLHttpRequest();
                xmlhttp.open("GET",xmlFile,false);
                xmlhttp.send(null);
                if(xmlhttp.readyState == 4){
                xmlDoc = xmlhttp.responseXML.documentElement;
                }
            }

            return xmlDoc;
        }

        // 首先對xml對象進行判斷
      var  checkXMLDocObj = function (xmlFile) {
            var xmlDoc = loadXML(xmlFile);
            if (xmlDoc == null) {
                alert('您的瀏覽器不支持xml文件讀取,於是本頁面禁止您的操作,推薦使用IE5.0以上可以解決此問題!');
                window.location.href = '../err.html';

            }
            return xmlDoc;
        }

2、將讀取到的xml文件中的數據顯示到html文檔上

<script type="text/javascript" language="javascript">
        var xmlDoc = checkXMLDocObj('../openClass.xml');//讀取到xml文件中的數據
        var a = document.getElementsByTagName("a");//獲取所有的A標簽
        $(document).ready(function () {
              var nodes;
            if($.browser.msie){ // 注意各個瀏覽器之間的區別
             nodes = xmlDoc.getElementsByTagName('collage')[0].childNodes; //讀取XML文件中需要顯示的數據
             }
             else if (isFirefox=navigator.userAgent.indexOf("Firefox")>0){
                nodes = xmlDoc.getElementsByTagName('collage')[0].children; //讀取XML文件中需要顯示的數據
             }
             else{
                nodes = xmlDoc.getElementsByTagName('resource');
             }
            
             for (var i = 0; i < a.length; i++) {
                if (a[i].parentNode.nodeName == "SPAN") {
                    for (var j = 0; j < nodes.length; j++) {
                        var resource = nodes[j];
                        var url = resource.getAttribute('url');
                        var href=$(a[i]).attr("href");
                        if (href == url) {
                            var count = resource.getAttribute('click');
                            var span = document.createElement("div");
                            var str = document.createTextNode("點擊率：" + count);
                            span.appendChild(str);
                            var div = a[i].parentNode.parentNode;
                            div.appendChild(span);
                            break;
                        }
                    }
                }
            }
        });
                $(function(){ //通過get請求，將點擊率增加
                 $(a).mousedown(function(){
                             var href = $(this).attr("href");
                            $.get("../receive.ashx",{url:href,rd:Math.random()}, function (msg) {
                            
                            });
                        })
        })  
    </script>
