常用计算机浏览器名称,javascript-如何从浏览器读取客户端的计算机名称？

尝试使用下面给出的代码在Mozilla Firefox中获取客户端计算机名称。

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;

同样，可以将同一段代码作为扩展名放置，并且可以从您的网页中调用它。

请在下面找到示例代码。

扩展代码：

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：

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.

}
