我在JavaScript中使用了哈希表,我想展示以下哈希表的值
one -[1,10,5]
two -[2]
three -[3, 30, 300, etc.]
我找到了以下代码。它适用于以下数据。
one -[1]
two -[2]
three-[3]
如何将一个一维数组 [1,2] 赋值给哈希表,并且如何访问它?
<script type="text/javascript">
function Hash()
{
this.length = 0;
this.items = new Array();
for (var i = 0; i < arguments.length; i += 2) {
if (typeof(arguments[i + 1]) != 'undefined') {
this.items[arguments[i]] = arguments[i + 1];
this.length++;
}
}
this.removeItem = function(in_key)
{
var tmp_value;
if (typeof(this.items[in_key]) != 'undefined') {
this.length--;
var tmp_value = this.items[in_key];
delete this.items[in_key];
}
return tmp_value;
}
this.getItem = function(in_key) {
return this.items[in_key];
}
this.setItem = function(in_key, in_value)
{
if (typeof(in_value) != 'undefined') {
if (typeof(this.items[in_key]) == 'undefined') {
this.length++;
}
this.items[in_key] = in_value;
}
return in_value;
}
this.hasItem = function(in_key)
{
return typeof(this.items[in_key]) != 'undefined';
}
}
var myHash = new Hash('one',1,'two', 2, 'three',3 );
for (var i in myHash.items) {
alert('key is: ' + i + ', value is: ' + myHash.items[i]);
}
</script>
我该怎么做?
