您好我目前有以下XML文件和我的脚本。
<ResourcesList>
<ResourceGroup type = "HUMANS">
<ResourcesInfo JobPosition = "Station Manager" OnDuty = "40" OnLeave_Local = "1" OnLeave_Oversea = "1" MC = "2" />
<ResourcesInfo JobPosition = "Deputy Station Manager" OnDuty = "82" OnLeave_Local = "5" OnLeave_Oversea = "5" MC = "2" />
</ResourceGroup>
<ResourceGroup type = "MACHINES">
<ResourcesInfo MachineName = "Leopard 2SG" MachineID = "SB1420J" MachineType = "Battle Tank" Available = "15" NotAvailable = "2" />
<ResourcesInfo MachineName = "M113A2 ULTRA OWS" MachineID = "SS4020J" MachineType = "Transport Vechicle" Available = "50" NotAvailable = "21" />
</ResourceGroup>
</ResourcesList>
<script>
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","ResourceList.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("ResourceGroup");
for (i=0;i<x.length;i++)
{
document.write("<tr><td>");
document.write(x[i].getElementsByTagName("ResourcesInfo")[0].childNodes[0].nodeValue);
}
document.write("</table>");
</script>
任何人都可以帮忙吗?我按照w3school中的示例并尝试将其写出来,但它告诉我以下错误。
TypeError: x[i].getElementsByTagName(ResourcesInfo)[0].childNodes[0] is undefined.

Here我已经为你修复了解析逻辑。
而且,这就是魔术发生的地方:
document.write("<table border='1'>");
var x = xmlDoc.getElementsByTagName("ResourceGroup");
for (i = 0; i < x.length; i++) {
document.write("<tr>");
var y = x[i].getElementsByTagName("ResourcesInfo");
for (j = 0; j < y.length; j++) {
if (x[i].getAttribute("type") == "HUMANS") {
document.write("<td>" + y[j].getAttribute('JobPosition') + "</td>");
} else {
document.write("<td>" +y[j].getAttribute('MachineName') + "</td>");
}
}
document.write("</tr>");
}
document.write("</table>");
}
使用代码解析并创建所需的HTML表结构。

我正在获取值...(虽然未定义,因为它们内部没有任何文本)。
检查任何拼写错误。我已经修改过
document.write(x[i].getElementsByTagName("ResourcesInfo")[0].childNodes[0].nodeValue);
到
document.write(x[i].getElementsByTagName("ResourcesInfo")[0].childNodes[0]);
。
BTW您的预期产量是多少?这是我的截图...
