该公司最近发现需要在 Visualforce / Apex 中创建并排记录比较。我们通常需要将潜在客户合并到联系人中。以前这是在 S-Controls 中处理的；但是，最近的举措和希望在未来支持我们的代码的愿望促使我们将许多 S-Control 移动到 Visualforce 页面和 Apex 代码中。
我们正在寻求实现这样的目标：
apex:pageBlockTable我已经使用标签进行了一些实验（运气不佳） ；但是，我不确定在需要单个 SObject 时如何获取两组数据进行渲染。
我之前必须使用的所有代码都是在 S-Controls 中使用 JavaScript 完成的；虽然这段代码现在可以工作 - 我们需要将它移植到 VisualForce 页面。显然，我可以使用 HTML 表格等手动编写它，但我认为这违背了使用股票 Salesforce 功能的目的。
我绝对对替代方法持开放态度 - 正如我所概述的那样，但需要几乎痛苦的编码才能使其可行（尤其是在将来更新/删除/添加字段时）。
答案最终非常直截了当！
首先- 事实证明，apex:pageBlockTable可以处理传递给参数的几乎任何类型的对象value，无论是 SObjects 数组还是 MyFooBar 对象数组。
其次- 我们需要一个包装类来同时封装两条记录：
public with sharing class LeadContactCompareWrapper {
public static final String SALUTATION = 'Salutation';
public static final String FIRST_NAME = 'First Name';
public static final String LAST_NAME = 'Last Name';
public static final String EMAIL = 'Email';
public static final String PHONE = 'Phone';
public static final String STREET = 'Street';
public static final String CITY = 'City';
public static final String STATE = 'State';
public static final String COUNTRY = 'Country';
public static final String ZIP_POSTAL = 'Zip / Postal Code';
public static final String TITLE = 'Title';
public static final String PRIMARY_FUNCTIONAL_ROLE = 'Primary Functional Role';
public static final String SECONDARY_FUNCTIONAL_ROLE = 'Secondary Functional Role';
public static final String BULLETIN = 'Bulletin';
public static final String CREDIT_MEMO = 'Credit Memo';
public static final String FS_INSIGHTS = 'FS Insights';
public static final String MANUFAC_IND_INSIGHTS = 'Manufact. Ind Insights';
public static final String LIT_AND_FRAUD = 'Lit. & Fraud News';
public static final String REGULATORY_INSIGHTS = 'Regulatory Insights';
private Lead lead;
private Contact contact;
public List<Compare> information { get; set; }
public List<Compare> marketing { get; set; }
public List<Compare> furtherDetails { get; set; }
public List<SelectOption> names { get;set; }
public String newName { get;set; }
public Id getContactId() {
return this.contact.Id;
}
public Id getAccountId() {
return this.contact.Account.Id;
}
public Id getLeadId() {
return this.lead.Id;
}
public Lead getLead() {
return this.lead;
}
public Contact getContact() {
return this.contact;
}
public LeadContactCompareWrapper(Lead lead, Contact contact) {
this.lead = [Select Id, DeliveryPreference__c, ACE__c,AML__c,BusContinuity__c,CorpGovSOX__c,ERM__c,FinancialRisk__c,InternalAudit__c,ITAsset__c,ITAudit__c,ITSecurity__c,LitSupport__c,ORM__c,SelfAssessment__c,SpendRisk__c, Owner.Name, Company, Bulletin__c,Credit_Memo__c,FSInsights__c,Manufact_Ind_Insights__c,LitFraudNews__c,RegulatoryInsights__c, LastModifiedDate, Salutation, FirstName, LastName, Email, Phone, Street, City, State, Country, PostalCode, Title, Primary_Functional_Role__c, SecondaryFunctionalRole__c From Lead Where Id = :lead.Id];
this.contact = [Select Id, Owner.Name, Account.Id, Account.Name, Bulletin__c,Credit_Memo__c,FSInsights__c,Manufact_Ind_Insights__c,LitFraudNews__c,RegulatoryInsights__c, LastModifiedDate, Salutation, FirstName, LastName, Email, Phone, MailingStreet, MailingCity, MailingState, MailingCountry, MailingPostalCode, Title, Primary_Functional_Role__c, SecondaryFunctionalRole__c From Contact Where Id = :contact.Id];
this.init();
}
private void init() {
this.information = new List<Compare>();
this.marketing = new List<Compare>();
this.furtherDetails = new List<Compare>();
// this part will suck but it has to be done
information.add(this.createCompare(SALUTATION,
(this.lead.Salutation != null) ? this.lead.Salutation : '',
(this.contact.Salutation != null) ? this.contact.Salutation : ''
));
/* Continue adding as many compare fields for the 'information' section as needed... */
// Marking Subscriptions
marketing.add(this.createCompare(BULLETIN,
(this.lead.Bulletin__c != null) ? this.lead.Bulletin__c : '',
(this.contact.Bulletin__c != null) ? this.contact.Bulletin__c : ''
));
/* Continue adding as many compare fields for the 'marketing' section as needed... */
// Further information - just for display purposes
furtherDetails.add(this.createCompare('Owner',
(this.lead.Owner.Name != null) ? this.lead.Owner.Name : '',
(this.contact.Owner.Name != null) ? this.contact.Owner.Name : '',
false,
true
));
/* Continue adding as many compare fields for the 'further information' section as needed... */
}
/*
* Creates a comparison object
*/
private Compare createCompare(string label, String val1, String val2, Boolean isVal1, Boolean isVal2) {
Compare c = new Compare(label);
c.selectVal1 = isVal1;
c.selectVal2 = isVal2;
c.val1 = val1;
c.val2 = val2;
return c;
}
/*
* Defaults our comparison to value 1 as selected
*/
private Compare createCompare(String label, String val1, String val2) {
return createCompare(label, val1, val2, true, false);
}
}
第三- 我们需要创建一个“比较”类，它包含两个值和两个布尔值，基于选择的值（以及要在表格上显示的行标签）：
public class Compare {
public Compare (String label) {
this.label = label;
}
public String label { get; set; }
public Boolean selectVal1 { get; set; }
public Boolean selectVal2 { get; set; }
public String val1 { get; set; }
public String val2 { get; set; }
}
然后就像把它全部放在一个 VF 页面上一样简单，如下所示：
<apex:pageblocktable value="{!leadToContact.information}" var="compare">
<apex:column>
<apex:facet name="header">Information</apex:facet>
{!compare.label}
</apex:column>
<apex:column>
<apex:facet name="header">Lead</apex:facet>
<apex:inputcheckbox id="val1" label="{!compare.val1}" onclick="uncheckOtherCompare(this);" title="{!compare.val1}" value="{!compare.selectVal1}" />
<apex:outputlabel value="{!compare.val1}" />
</apex:column>
<apex:column>
<apex:facet name="header">Contact</apex:facet>
<apex:inputcheckbox id="val2" label="{!compare.val2}" onclick="uncheckOtherCompare(this);" value="{!compare.selectVal2}" />
<apex:outputlabel value="{!compare.val2}" />
</apex:column>
</apex:pageblocktable>
最后，我们只需要一点 javascript 来使单选按钮正常运行 :)
function uncheckOtherCompare(obj) {
// Get the id of the object being checked
var objId = obj.id;
if (objId.indexOf('val1') >= 0) {
objId = objId.replace('val1', 'val2');
} else {
objId = objId.replace('val2', 'val1');
}
if (obj.checked) {
document.getElementById(objId).checked = false;
} else if (!document.getElementById(objId).checked) {
// If the user is trying to uncheck both boxes, recheck the box that is being passed in.
// We can't have 'no' boxes checked on a given row
obj.checked = true;
}
}
javascript 几乎可以放置在页面上的任何位置，但最好将其链接或放置在开始标记之后的文档顶部。
完成此操作后，您可以（从代码中）访问您的LeadContactCompareWrapper.[information|marking|furtherDetails]数组并逐步检查每个数组以确定所选值，或编写其他帮助程序类以加快该过程。
有了这个，我们能够创建一个并排的记录比较，使我们能够将我们的潜在客户直接合并到我们的联系人中！
