我想用java腳本解析一個簡單的xml文件。當我將文件加載到webrowser「Chrome」中時,該頁面不顯示任何內容。 當使用Javascript解析XML文件時,Web瀏覽器不顯示任何東西
請讓我知道我的錯誤是什麼。
XML文件:
< ?xml version="1.0" encoding="UTF-8" ?>
<company>
<employee id="001" >John</employee>
<turnover>
<year id="2000">100,000</year>
<year id="2001">140,000</year>
<year id="2002">200,000</year>
</turnover>
</company>
JavaScript分析器:
Read XML in Microsoft Browsers</title>
<script type="text/javascript">
var xmlDoc;
function loadxml()
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.onreadystatechange = readXML; /* to be notified when the state changes */
xmlDoc.load("C:\Users\Amr\Desktop\files\xml.xml");
}
function readXML()
{
if(xmlDoc.readyState == 4)
{
//Using documentElement Properties
//Output company
alert("XML Root Tag Name: " + xmlDoc.documentElement.tagName);
//Using firstChild Properties
//Output year
alert("First Child: " + xmlDoc.documentElement.childNodes[1].firstChild.tagName);
//Using lastChild Properties
//Output average
alert("Last Child: " + xmlDoc.documentElement.childNodes[1].lastChild.tagName);
//Using nodeValue and Attributes Properties
//Here both the statement will return you the same result
//Output 001
alert("Node Value: " + xmlDoc.documentElement.childNodes[0].attributes[0].nodeValue);
alert("Node Value: " + xmlDoc.documentElement.childNodes[0].attributes.getNamedItem("id").nodeValue);
//Using getElementByTagName Properties
//Here both the statement will return you the same result
//Output 2000
alert("getElementsByTagName: " + xmlDoc.getElementsByTagName("year")[0].attributes.getNamedItem("id").nodeValue);
//Using text Properties
//Output John
alert("Text Content for Employee Tag: " + xmlDoc.documentElement.childNodes[0].text);
//Using hasChildNodes Properties
//Output True
alert("Checking Child Nodes: " + xmlDoc.documentElement.childNodes[0].hasChildNodes);
}
我試圖加載在IE文件,但它沒有工作 –
如果您查看控制檯下的開發人員工具欄,它會給你什麼錯誤消息? –
