Grails翻译 - Load On-Demand

 

你需要为本教程准备一个Grails程序,输入:

$ grails create-app ondemand

下一步,你需要安装ZKGrails.当输入下面的命令最新的版本将会被自动安装:

$ grails install-plugin zk

你将使用一个域类@R_450_8750@yee去演示本插件.简单的使用create-domain-class命令在Grails中创建域类,并紧跟着你的类名:

$ grails create-domain-class @R_450_8750@yee

接着往@R_450_8750@yee中添加两个属性fullname的username类型为String.

@H_403_27@class @R_450_8750@yee { String fullname String username static consTraints = { } }

$ grails create-zul @R_450_8750@yee

@H_403_27@ <window apply="${@R_450_8750@yeeComposer}">

 

你可能注意到afterCompose闭包.这个闭包将通过doAfterCompose执行,并在Groovy里初始化你的容器.

任何时候点击pag@R_450_8750@yee换页,这个auto-wired事件处理器onPaging_pag@R_450_8750@yee将会执行.注,处理器工作需要的参数只能是ForWARDEvent或Event.

 

@H_403_27@import org.zkoss.zkgrails.* import org.zkoss.zk.ui.event.* class @R_450_8750@yeeComposer extends GrailsComposer { def lstemployee def pag@R_450_8750@yee def afterCompose = { c -> pag@R_450_8750@yee.@R_644_10586@lSize = @R_450_8750@yee.count() redraw() } def onPaging_pag@R_450_8750@yee(ForWARDEvent fE) { def e = fe.origin redraw(e.activePagE) } def redraw(page=0) { def list = @R_450_8750@yee.list(offset: page * pag@R_450_8750@yee.pageSize,max: pag@R_450_8750@yee.pageSizE) lstemployee.clear() lstemployee.append { list.each { e -> listitem(value: E) { listcell(label: e.id) listcell(label: e.fullName) listcell(label: e.userName) } } } } }

首先在执行你的程序前,你需要一些展示的测试数据.打开grails-app/conf/BootStrap.groovy,并添加下面的代码到init闭包里.

@H_403_27@def init = { servletContext -> 1000.times { i -> new @R_450_8750@yee(fullname: "Name $i",username: "user$i").save() } }
