在偵聽器方法執行後調用Onstart

Question

爲什麼在偵聽器方法執行後調用onstart？ 在偵聽器方法執行之前，我應該怎樣調用onstart方法？ 使用jsf 2.1和primefaces 4.0。

<p:ajax event="eventMove" listener="#{myBean.onEventMove}" 
    update="mygrwlmsg" onstart="setLStorageDateToBean();" 
    oncomplete="if(args.facesMessagesAvailable){handleEditEventRequest(args.eventList);scheduleWidget.update();}" /> 

通過remoteCommand

調用bean方法

function setLStorageDateToBean() 
{ 
    if(typeof(Storage)!=='undefined') 
    { 
     if((localStorage.startDate || localStorage.getItem('startDate') != null) 
      && (localStorage.endDate || localStorage.getItem('endDate') != null)) 
     { 
      var sDate = parseInt((localStorage.startDate)/1000); 
      var eDate = parseInt((localStorage.endDate)/1000); 
      var lCalRefresh = parseInt((localStorage.lastCalRefresh)/1000); 

      setLocalStorageDate([{name:'startDate',value:sDate},{name:'endDate',value:eDate},{name:'lastCalRefresh',value:lCalRefresh}]);    
     } 
    } 
} 

<p:remoteCommand name="setLocalStorageDate" actionListener="#{myBean.setDateFromLocaStorage}" > 
</p:remoteCommand> 

bean方法

public void setDateFromLocaStorage() 
{ 
    int startDate = Integer.parseInt(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("startDate")); 
    int endDate = Integer.parseInt(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("endDate")); 
    int lCalRefresh = Integer.parseInt(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("lastCalRefresh")); 

    setlStorStartDate(startDate); 
    setlStorEndDate(endDate); 
    setlStorLastRefresh(lCalRefresh);  
}

實測值的溶液中。 修改阿賈克斯（刪除偵聽）

<p:ajax event="eventMove" 
    update="mygrwlmsg" onstart="callOnAjax();" 
    oncomplete="if(args.facesMessagesAvailable)handleEditEventRequest(args.eventList); 
    scheduleWidget.update();}" /> 

創建一個新的remoteCommand組件

<p:remoteCommand name="myListener" actionListener="#{myBean.onEventMove}"> 
</p:remoteCommand> 

創建一個新的JavaScript函數

function callOnAjax(){ 
    setDateFromLocaStorage(); 
    myListener(); 
}
