在我的 VF 页面中，我有 7 个部分代表一周中的几天。每个部分都有“添加多个时间表项目”按钮。单击该按钮时，将显示新行，其中包含要填写的字段（项目、工作小时数..）。因此，我有 7 个具有相同操作的按钮，例如，当我单击第 1 部分中的按钮时，操作会在每个部分中执行，我不希望这样。我只想在单击按钮的部分执行。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;
    }
    
}

这不是“在每个部分都执行操作”。您渲染相同的变量 7 次。如果您将小时数输入为 1,2,3,4,5,6,7，我希望它会节省 7，因为这是表格上最后一次提到这一点，该字段的值将“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<apex:param>的数字，从 0 到 6，说明向哪个添加新项目。请注意，传递参数时<apex:commandButton> 有点愚蠢。

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，在按钮中传递地图键。
