EasyUI项目之书籍管理（CRUD）
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
在上節(jié)課的基礎(chǔ)上對(duì)書籍管理增加CRUD操作
目標(biāo)效果：
目標(biāo)：
1，點(diǎn)擊新增，類型將會(huì)在下拉框中顯示，增加成功后，該書會(huì)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(tài)）。
3，已下架，查詢狀態(tài)為下架的書籍。
4，修改，在未上架中可選中書籍進(jìn)行修改。
打開選項(xiàng)卡 （在上節(jié)課基礎(chǔ)上完善選項(xiàng)卡功能）
$(function() {$("#bookMenus").tree({url:$("#ctx").val()+"/permission.action?methodName=tree",onClick:function(node){//判斷有無重復(fù)選項(xiàng)卡var exists=$('#bookTabs').tabs('exists',node.text);if(exists){//存在則選中$('#bookTabs').tabs('select',node.text);}else{//不存在則打開新的選項(xiàng)卡$('#bookTabs').tabs('add',{ title:node.text, //node.attributes.self.menuURL決對(duì)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
