尝试使用下面给出的代码在MozillaFirefox中获取客户端计算机名。
netscape.security.PrivilegeManager.enablePrivilege( 'UniversalXPConnect' );
var dnsComp = Components.classes["@mozilla.org/network/dns-service;1"];
var dnsSvc = dnsComp.getService(Components.interfaces.nsIDNSService);
var compName = dnsSvc.myHostName;
此外，同一段代码可以作为扩展，并可以从您的网页调用。
请查找下面的示例代码。
分机代码：
var myExtension = {
myListener: function(evt) {
//netscape.security.PrivilegeManager.enablePrivilege( 'UniversalXPConnect' );
var dnsComp = Components.classes["@mozilla.org/network/dns-service;1"];
var dnsSvc = dnsComp.getService(Components.interfaces.nsIDNSService);
var compName = dnsSvc.myHostName;
content.document.getElementById("compname").value = compName ;
}
}
document.addEventListener("MyExtensionEvent", function(e) { myExtension.myListener(e); }, false, true); //this event will raised from the webpage
网页代码：
<html>
<body onload = "load()">
<script>
function showcomp()
{
alert("your computer name is " + document.getElementById("compname").value);
}
function load()
{
//var element = document.createElement("MyExtensionDataElement");
//element.setAttribute("attribute1", "foobar");
//element.setAttribute("attribute2", "hello world");
//document.documentElement.appendChild(element);
var evt = document.createEvent("Events");
evt.initEvent("MyExtensionEvent", true, false);
//element.dispatchEvent(evt);
document.getElementById("compname").dispatchEvent(evt); //this raises the MyExtensionEvent event , which assigns the client computer name to the hidden variable.
}
</script>
<form name="login_form" id="login_form">
<input type = "text" name = "txtname" id = "txtnamee" tabindex = "1"/>
<input type="hidden" name="compname" value="" id = "compname" />
<input type = "button" onclick = "showcomp()" tabindex = "2"/>
</form>
</body>
</html>
