EasyUI项目之书籍管理（CRUD）
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在上節課的基礎上對書籍管理增加CRUD操作
目標效果：
目標：
1，點擊新增，類型將會在下拉框中顯示，增加成功后，該書會顯示到未上架界面中。
2，未上架，已上架（上架，下架書籍是改變書籍的狀態）。
3，已下架，查詢狀態為下架的書籍。
4，修改，在未上架中可選中書籍進行修改。
打開選項卡 （在上節課基礎上完善選項卡功能）
$(function() {$("#bookMenus").tree({url:$("#ctx").val()+"/permission.action?methodName=tree",onClick:function(node){//判斷有無重復選項卡var exists=$('#bookTabs').tabs('exists',node.text);if(exists){//存在則選中$('#bookTabs').tabs('select',node.text);}else{//不存在則打開新的選項卡$('#bookTabs').tabs('add',{ title:node.text, //node.attributes.self.menuURL決對路徑content:'<iframe width="100%" height="100%" src="'+$("#ctx").val()+node.attributes.self.url+'"></iframe>', closable:true, tools:[{ iconCls:'icon-mini-refresh', handler:function(){ alert('refresh'); } }] });}}}); })一，增加
1.1 ComboBox（利用ComboBox控件制作下拉列表框）
實體類
CategoryDao
CategoryAction
