jQuery does not (out of the box).
jQuery 没有（开箱即用）。
However, James Padolsey created this prettyPrintwhich I really like.
然而，James Padolsey 创造了这个我非常喜欢的漂亮印刷品。
Also, if you're using Firebug or Web Inspector (or similar), you can just type the object into the console, press return, and see a tree-dump of the object. To force a tree-view, call console.dir(obj)
此外，如果您使用 Firebug 或 Web Inspector（或类似工具），您只需在控制台中键入对象，按return，即可查看对象的树状转储。要强制树视图，请调用console.dir(obj)

Although the accepted answer is correct that jQuery does not have a pretty print feature for JSON, that feature is now included in out of the box javascriptthrough JSON.stringify()'sspace argument. To print to HTML, wrapping the output with <pre> </pre>will preserve the line spacingfor readability purposes.
尽管接受的答案是正确的，jQuery 没有用于 JSON 的漂亮打印功能，但该功能现在通过JSON.stringify()'sspace 参数包含在开箱即用的 javascript 中。要打印到 HTML，将输出包装起来<pre> </pre>将保留行间距以提高可读性。
var obj = {a:1, 'b':'foo', c:[false,'false',null, 'null', {d:{e:1.3e5,f:'1.3e5'}}]};
var str = "<pre>" + JSON.stringify(obj, undefined, 4) + "</pre>";
/* Returns
{
"a": 1,
"b": "foo",
"c": [
false,
"false",
null,
"null",
{
"d": {
"e": 130000,
"f": "1.3e5"
}
}
]
}

Using Jquery, you can have object.serialize()to output an object. This is similar to var_dump()in php or Zend_Debug::dump()in Zend.
使用 Jquery，您可能必须 object.serialize()输出一个对象。这类似于var_dump()在 php 或Zend_Debug::dump()Zend 中。
