1、javascript的console.log()用法
2、源码：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<script type="text/javascript">
//变量
var i = 'I am a string';
console.log('变量：', i);
//数组
var arr = [1, 2, 3, 4, 5];
console.log('数组：', arr);
//对象
var obj1 = {
key1: 'value1',
key2: 'value2',
key3: 'value3'
};
var obj2 = {
key6: 'value4',
key5: 'value5',
key4: 'value6'
};
var obj3 = {
key9: 'value7',
key8: 'value8',
key7: 'value9'
};
console.log('对象：', obj1);
//对象数组
var objArr1 = [obj1, obj2, obj3];
var objArr2 = [[obj1], [obj2], [obj3]];
console.log('对象数组1：', objArr1);
console.log('对象数组1：', objArr2);
</script>
</head>
<body>
</body>
</html>
3、生成的结果（在firebug中查看的结果）
对象数组1：
[Object{ key1="value1",key2="value2",key3="value3"},Object{ key6="value4",key5="value5",key4="value6"},Object{ key9="value7",key8="value8",key7="value9"}]
NewFile.html (第 38 行)
对象数组1：
[[Object{ key1="value1",key2="value2",key3="value3"}],[Object{ key6="value4",key5="value5",key4="value6"}],[Object{ key9="value7",key8="value8",key7="value9"}]]
