本文執行個體講述了JS通過ajax動態讀取xml檔案內容的方法。分享給大家供大家參考。具體分析如下：
下面的JS代碼讀取note.xml檔案，並填充顯示相關欄位
HTML檔案代碼如下
<!DOCTYPE html><html><head><script>function loadXMLDoc(url){var xmlhttp;if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById('A1').innerHTML=xmlhttp.status; document.getElementById('A2').innerHTML=xmlhttp.statusText; document.getElementById('A3').innerHTML=xmlhttp.responseText; } }xmlhttp.open("GET",url,true);xmlhttp.send();}</script></head><body><h2>Retrieve data from XML file</h2><p><b>Status:</b><span id="A1"></span></p><p><b>Status text:</b><span id="A2"></span></p><p><b>Response:</b><span id="A3"></span></p><button onclick="loadXMLDoc('note.xml')">Get XML data</button></body></html>
xml檔案內容如下
<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note>
