Can not load xml file in javascript
提问by Sarfraz Ahmed
I am trying to load an xml file that is on my local system. But I always get Network_err. I do the following.
我正在尝试加载本地系统上的 xml 文件。但我总是得到 Network_err。我执行以下操作。
function LoadXmlDoc(dName)
{
var xhttp;
if(window.XMLHttpRequest)
{
xhttp = new XMLHttpRequest();
}
else
{
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
try
{
xhttp.open("GET", "file.xml", false);
xhttp.send();
}
catch(e)
{
window.alert("Unable to load the requested file.");
return;
}
return xhttp.responseXML;
}

Try:
尝试：
function XMLDoc()
{
if (window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
alert(xmlhttp.responseText);
}
};
xmlhttp.open("GET","yourfile",true);
xmlhttp.send();
}
Updateddue to simplify
由于简化而更新
Invoke XMLDoc()and pass your file uri instead of yourfile
调用XMLDoc()并传递您的文件 uri 而不是yourfile
Note: Don't forget to run this script on server
