具有相同操作的多个按钮

Question

在我的VF页面中，我有7个部分表示一周中的几天。每个部分都有“添加多个时间表项目”按钮。单击该按钮时，将显示新的行，其中包含要填充的字段(项目、工作小时数..)。因此，我有7个按钮具有相同的操作，当我单击，例如，在第一部分的按钮上，操作在每个部分执行，我不想要这种情况。我只想在点击按钮的部分执行。这是我在VF页面中的代码：

<apex:page Controller="TimesheetController">

    <apex:pageBlockSection title="Contentment, PTO" columns="1">
        <br/>
        <apex:inputField label="Mood" value="{!timesheet.Mood__c}"/>
        <br/>
        <apex:inputTextarea label="Upcoming PTO" value="{!timesheet.Upcoming_PTO__c}" rows="5" cols="30"/>

        </apex:outputPanel>
    </apex:pageBlockSection>

</apex:pageBlock>
</apex:form>
</apex:page>

这是我的控制器：

public class TimesheetController{
    
    Timesheet_Item__c item = new Timesheet_Item__c();
    public list<Timesheet_Item__c> listItems{get; set;}
    public Timesheet__c timesheet{get; set;} 

    public TimesheetController () {
        timesheet = new Timesheet__c();
        listItems = new list<Timesheet_Item__c>();
        listItems.add(item);
    }
 
    public void addItem() {
        Timesheet_Item__c sheet_item = new Timesheet_Item__c();
        listItems.add(sheet_item);
    }

    public PageReference saveDetails() {
        for(Integer i=0; i<listItems.size(); i++) {
            insert listItems;
        }
        insert timesheet;
        return null;
    }
    
}

Answer 1

这并不是“每个部分都执行操作”。您呈现相同的变量7次。如果输入小时数为1,2,3,4,5,6,7，我希望它会节省7，因为这是最后一次在表单中提到这一点，这个字段的值将“获胜”。

您需要一个列表列表：

List<List<Timesheet_Item__c>> l = new List<List<Timesheet_Item__c>>{
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>(),
    new List<Timesheet_Item__c>()
};

然后在按钮操作中，您可以传递额外的<apex:param>，其数字从0到6，表示向哪个添加新项。在传递参数时要当心，<apex:commandButton> is bit stupid。

或者可能是Map<String, List<Timesheet_Item__c>> = new Map<String, List<Timesheet_Item__c>>{ 'Monday' => new List<Timesheet_Item__c>(), ...};相同的原理，在按钮中传递map键。
