1.dictionary例子
- <script type="text/javascript" language="javascript">
- var dict = new Array();
- dict["人"] = "ren";
- dict["口"] = "kou";
- dict["手"] = "shou";
- alert(dict["口"]);
- for (var i in dict) {
- alert(i);
- alert(dict[i]);
- }
- </script>
等同于上面的赋值：
- var dict = { "人": "ren", "口": "kou", "手": "shou" };
3.push，像数组最后继续添加元素
var dict = new Array(1,4,5,6,7);
dict.push(22,33,22,221);
4,删除元素--只删除元素，但是数组长度 不变，删掉的元素变成undefined
var d = new Array(44, 22, 33, 22, 11, 33);
delete d[0];
