Try using console.dir() instead of console.log() - this will also work with other browsers' consoles. 尝试使用console.dir()而不是console.log() -这也可以与其他浏览器的控制台一起使用。

If you just want to see what's in the complex object without using full scale library, you can use such code: 如果您只想查看复杂对象中的内容而不使用完整比例的库，则可以使用以下代码：
var complexObject = {
"first field": "first value", "second": function() {
alert("hello");
},
"third": ["I", "am", "an", "array"]
};
var complexObjectString = "";
for (var key in complexObject) {
complexObjectString += key + ": " + complexObject[key] + "\n";
}
alert(complexObjectString);

In IE9 you need to be in standards mode to use the JSON object; 在IE9中，您需要处于标准模式才能使用JSON对象。 eg, you must have a doctype. 例如，您必须具有doctype。
This does not work: Live copy | 这不起作用： 实时复制 | source 资源
<html>
<head>
<meta charset=utf-8 />
<title>Test Page</title>
</head>
<body>
<p>Without a doctype</p>
<script>
(function() {
try {
var obj = {
foo: "bar"
};
var str = JSON.stringify(obj);
display("<code>" + str + "</code>");
}
catch (e) {
display("Exception: " + (e.message || e.toString()));
}
function display(msg) {
var p = document.createElement('p');
p.innerHTML = msg;
document.body.appendChild(p);
}
})();
</script>
</body>
</html>
It fails with an error that JSON is undefined. 失败，并显示一个错误，即未定义JSON 。
If you add 如果添加
<!doctype html>
to the top, it works: Live copy | 到顶部，它的工作原理是： 实时复制 | source 资源
