推荐答案

正如其他人所说，你可以使用Firebug，这将让你不用担心Firefox。 Chrome& Safari都有一个内置的开发人员控制台，它与Firebug的控制台具有几乎相同的界面，因此您的代码应该可以在这些浏览器中移植。对于其他浏览器，有 Firebug Lite 。

As the others said, you can use Firebug, and that will sort you out no worries on Firefox. Chrome & Safari both have a built-in developer console which has an almost identical interface to Firebug's console, so your code should be portable across those browsers. For other browsers, there's Firebug Lite.

如果Firebug不是你的选择，那么试试这个简单的脚本：

If Firebug isn't an option for you, then try this simple script:

function dump(obj) {
    var out = '';
    for (var i in obj) {
        out += i + ": " + obj[i] + "\n";
    }

    alert(out);

    // or, if you wanted to avoid alerts...

    var pre = document.createElement('pre');
    pre.innerHTML = out;
    document.body.appendChild(pre)
}

我建议反对警告每个人的财产：一些物品有很多属性，你会在那里整天点击确定，确定，确定，我......该死的那是我正在寻找的财产。

I'd recommend against alerting each individual property: some objects have a LOT of properties and you'll be there all day clicking "OK", "OK", "OK", "O... dammit that was the property I was looking for".
