使用jquery插件操作哈希表Hashtable的应用

jquery非常优秀，插件也非常非常的多，本文为大家介绍的比较特殊也经常使用的Hashtable插件，主要是以Array数组做成的Hashtable。

操作哈希表就非常好用，下面来看下源码：

 Code [http://www.isstudy.com]

jQuery.Hashtable = function () { this .items = new Array(); this .itemsCount = 0 ; this .add = function (key, value) { if ( ! this .containsKey(key)) { this .items[key] = value; this .itemsCount ; } else throw " key ' " key " ' allready exists. " } this .get = function (key) { if ( this .containsKey(key)) return this .items[key]; else return null ; } this .remove = function (key) { if ( this .containsKey(key)) { delete this .items[key]; this .itemsCount -- ; } else throw " key ' " key " ' does not exists. " } this .containsKey = function (key) { return typeof ( this .items[key]) != " undefined " ; } this .containsValue = function containsValue(value) { for ( var item in this .items) { if ( this .items[item] == value) return true ; } return false ; } this .contains = function (keyOrValue) { return this .containsKey(keyOrValue) || this .containsValue(keyOrValue); } this .clear = function () { this .items = new Array(); itemsCount = 0 ; } this .size = function () { return this .itemsCount; } this .isEmpty = function () { return this .size() == 0 ; } };

好，来看下使用方法：

 Code [http://www.isstudy.com]

var hashtable = new jQuery.Hashtable(); $( function () { $( ' #btnAdd ' ).click( function () { hashtable.add($( ' #txtAddKey ' ).val(), $( ' #txtAddValue ' ).val()); }); $( ' #btnGet ' ).click( function () { alert(hashtable.get($( ' #txtGetKey ' ).val())) }); })
