blocks|key|1570664|text|简单快捷的回答是否定的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570665|Javascript是一种相当高级的语言，无法访问此类信息。|1570666|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

<p>The quick and simple answer is No.</p>

<p>Javascript is quite a high level language and does not have access to this sort of information.</p>


blocks|key|1570694|text|如果这是针对intranet应用程序的，并且所有客户端都使用DHCP，则可以向DHCP服务器查询给定IP地址的MAC地址。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570695|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.</p>


blocks|key|1570745|text|不是的。ActiveX之所以能做到这一点，是因为ActiveX是一个运行在客户端机器上的小应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570746|我可以想象，通过JavaScript访问这些信息将是一个安全漏洞。|1570747|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

<p>Nope. The reason ActiveX can do it is because ActiveX is a little application that runs on the client's machine.</p>

<p>I would imagine access to such information via JavaScript would be a security vulnerability.</p>


blocks|key|1570817|text|不，您无法在JavaScript中获取MAC地址，主要是因为MAC地址唯一地标识了正在运行的计算机，因此这将是一个安全漏洞。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570818|现在，如果您所需要的只是一个唯一标识符，我建议您使用某种加密算法自己创建一个，并将其存储在cookie中。|1570819|如果您确实需要知道计算机的MAC地址，并且您正在为内部应用程序进行开发，那么我建议您使用外部组件来实现此目的:用于IE的ActiveX，用于Firefox的XPCOM+(作为扩展安装)。|1570820|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

<p>No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability.</p>

<p>Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.</p>

<p>If you really need to know the MAC address of the computer AND you are developing for internal applications, then I suggest you use an external component to do that: ActiveX for IE, XPCOM for Firefox (installed as an extension).</p>

<p>i was looking for the same problem and stumbled upon the following code.</p>

<p>How to get Client MAC address(Web):</p>

<p>To get the client MAC address only way we can rely on JavaScript and Active X control of Microsoft.It is only work in IE if Active X enable for IE. As the ActiveXObject is not available with the Firefox, its not working with the firefox and is working fine in IE.</p>

<p>This script is for IE only:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function showMacAddress() {
    var obj = new ActiveXObject("WbemScripting.SWbemLocator");
    var s = obj.ConnectServer(".");
    var properties = s.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
    var e = new Enumerator(properties);
    var output;
    output = '&lt;table border="0" cellPadding="5px" cellSpacing="1px" bgColor="#CCCCCC"&gt;';
    output = output + '&lt;tr bgColor="#EAEAEA"&gt;&lt;td&gt;Caption&lt;/td&gt;&lt;td&gt;MACAddress&lt;/td&gt;&lt;/tr&gt;';
    while (!e.atEnd()) {
        e.moveNext();
        var p = e.item();
        if (!p) continue;
        output = output + '&lt;tr bgColor="#FFFFFF"&gt;';
        output = output + '&lt;td&gt;' + p.Caption; +'&lt;/td&gt;';
        output = output + '&lt;td&gt;' + p.MACAddress + '&lt;/td&gt;';
        output = output + '&lt;/tr&gt;';
    }
    output = output + '&lt;/table&gt;';
    document.getElementById("box").innerHTML = output;
}

showMacAddress();</code></pre>

<p>No you can't obtain a user's MAC address using JavaScript in another way, just by using  active X op for Microsoft in IE browser</p>


<p>I know that we can get the MAC address of a user via IE (ActiveX objects).</p>

<p>Is there a way to obtain a user's MAC address using JavaScript?</p>


MAC addresses in JavaScript

服务器

DHCP

我知道我们可以通过IE (ActiveX对象)获取用户的MAC地址。有没有办法使用JavaScript获取用户的MAC地址？
