Prototype实战教程----14.Hash

<script src="prototype.js"></script>
<script>
// 创建一个对象
var obj = {
    key1: 1,
    key2: 2,
    key3: 3
};

// 将其转换为Hash对象
var hash = $H(obj);
// 输出 #<Hash: {'key1': 1, 'key2' : 2, 'key3': 3}>
// 输出key1=1&key2=2&key3=3
alert("hash.inspect()"+hash.inspect()+"\r\ntoQueryString:    "+hash.toQueryString()+"\r\n"+"values:   "+hash.values()+"\r\n keys:    "+hash.keys());
</script>
