Question

我有两个自定义对象，Category和Case，我将category设置为parent。类别中的列Category_ID由自定义对象Case引用。我在开发者控制台中执行了两个查询

SELECT Category_ID__c，id，Name FROM Category__c SELECT Category_ID__c，id，Name FROM Case__c 我发现Case中Category_ID的价值就像是＆＃39; a0D＆＃39; F000001MmjUae＆＃39;和＆＃39; a0D＆＃39; F000001MmjUde＆＃39;，但在类别中它＆＃39; 0＆＃39; 0和＆＃39; 1＆＃39;。

guard let

我希望根据选定的<apex:outputLabel value="Category" /> <apex:selectList value="{!categoryType}" size="1"> <apex:selectOptions value="{!items}"/> </apex:selectList> <apex:outputLabel value="Case" /> <apex:selectList value="{!caseId}" size="1"> <apex:selectOptions value="{!items2}"/> </apex:selectList> //From here is Controller public String categoryType{set;get;} public List<SelectOption> getItems(){ List<selectoption> mlst = new List<selectoption>(); for(VirtualCaseCategory__c m: [SELECT Category_ID__c, Name FROM VirtualCaseCategory__c]){ mlst.add(new selectoption(m.Id,m.Name)); } return mlst; } public List<SelectOption> getItems2(){ List<selectoption> mlst = new List<selectoption>(); for(VirtualCaseCases__c m: [SELECT Category_ID__c, Name FROM VirtualCaseCases__c WHERE Category_ID__c =:categoryType]){ mlst.add(new selectoption(m.Id,m.Name)); } return mlst; }值获得不同的Case selectList。谁能告诉我为什么？因为我想基于相同的Category_ID值运行一些查询。

我认为您未使用Category_Id__c循环在selectList中添加for。

for(VirtualCaseCategory__c m: [SELECT Category_ID__c, Name FROM VirtualCaseCategory__c]){
            // insert Category_ID__c in the select option
            mlst.add(new selectoption(m.Category_ID__c,m.Name));
        }

其他for循环

的情况也是如此

for(VirtualCaseCases__c m: [SELECT Category_ID__c, Name FROM VirtualCaseCases__c WHERE Category_ID__c =:categoryType]){
            // Same here as well
            mlst.add(new selectoption(m.Category_ID__c,m.Name));
        }

引用自定义字段ID
