这是非常复杂的方法。您是否真的需要所有这些“ outputLabel，InputText”等？如果您使用Apex：InputField（它神奇地知道字段标签以及字段类型是否为文本/日期/选择列表），则更简单，并且它也可以让您轻松显示查找。

当您无法做到这一点时，很少有这样的情况（需要绕过SF配置文件字段权限），但它在“我真的知道我在做什么”类别中。对于这些，如果您不能仅显示查找，则需要手工制作一些搜索 +自动完成解决方案。网络上应该有很多示例如何按名称功能创建VF+APEX搜索。

虽然这确实使轮子发动机。认真地考虑使用＆lt; apex：inputfield＆gt;

public class Stack72386167{

    public Contact con {get;set;}
    
    public Stack72386167(){
        con = new Contact();
    }
    
    public void save(){
        insert con;
    }
}

<apex:page controller="Stack72386167">
<apex:form>
    <apex:pageBlock>
        <apex:pageBlockButtons>
            <apex:commandButton value="Save" action="{!save}" />
        </apex:pageBlockButtons>
        <apex:pageBlockSection columns="1">
            <apex:inputField value="{!con.Salutation}" /> <!-- picklists -->
            <apex:inputField value="{!con.FirstName}" />
            <apex:inputField value="{!con.LastName}" />
            <apex:inputField value="{!con.AccountId}" />  <!-- lookups
            <apex:inputField value="{!con.Birthdate}" />  <!-- dates (and of course right field labels picked for "free", admin can change them without code changes -->
            
        </apex:pageBlockSection>
    </apex:pageBlock>
</apex:form>
</apex:page>
