本文介绍了如何使用 Salesforce 在案例类型中实施完整搜索?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要构建一个解决方案，在所有 3 个级别字段中的新案例类型数据对象上创建一个搜索字段，并根据选择进行填充.
与 SF Global Search 类似，我想在文本搜索字段中输入 2-3 个字符，它会在 Level1-3 字段中找到匹配的文本，并在选择时填充 Level 1-3 字段.
这是顶级课程
公共类 PickListHandler {@AuraEnabled公共静态列表getLevel1(){列表tempLst1 = new List();for(AggregateResult ar : [select Level_1__c,COUNT(id) from Case_Type_Data__c group by Level_1__c]){tempLst1.add(''+ar.get('Level_1__c'));}返回 tempLst1;}@AuraEnabled公共静态列表getLevel2(string strName){列表tempLst2 = new List();for(AggregateResult ar : [select Level_2__c,COUNT(id) from Case_Type_Data__c where Level_1__c=:strName group by Level_2__c]){tempLst2.add(''+ar.get('Level_2__c'));}返回 tempLst2;}@AuraEnabled公共静态列表getLevel3(string strName1,string strName2){列表tempLst3 = new List();for(AggregateResult ar : [select Level_3__c,COUNT(id) from Case_Type_Data__c where Level_1__c=:strName1 and Level_2__c=:strName2 group by Level_3__c]){tempLst3.add(''+ar.get('Level_3__c'));}返回 tempLst3;}@AuraEnabledpublic static String savecasetype(string level1,string level2,string level3,string id){字符串 strMsg='successfull';尝试{ERT_Case_Type__c obj=new ERT_Case_Type__c();Obj.Case__c = id;System.debug('CASE = '+ Obj.Case__c);Obj.Level_1__c=level1;System.debug('Level1 = '+ Obj.Level_1__c);obj.Level_2__c=level2;System.debug('Level2 = '+ Obj.Level_2__c);obj.Level_3__c=level3;System.debug('Level3 = '+ Obj.Level_3__c);插入对象；}捕获(异常前){strMsg='错误';}返回字符串；}}这是选择列表处理程序组件
Apex 类
public with share class Stack64129038 {@AuraEnabled(可缓存=真)公共静态列表search(String searchTerm, List selectedIds){if(String.isBlank(searchTerm) || searchTerm.length() 记录 = [SELECT Id, Name, Level_1__c, Level_2__c, Level_3__cFROM Case_Type_Data__cWHERE Level_1__c LIKE :t OR Level_2__c LIKE :t OR Level_3__c LIKE :t按 Level_1__c、Level_2__c、Level_3__c 排序限制 20]；/* 你也可以试验 SOSL?记录 = [FIND :('*' + searchTerm + '*') 在所有字段中返回 Case_Type_Data__c(Id, Name, Level_1__c, Level_2__c, Level_3__c)][0];*/列表结果 = 新列表();for(Case_Type_Data__c ctd:记录){results.add(new LookupSearchResult(ctd.Id, 'Case_Type_Data__c', 'standard:case_wrap_up', ctd.Name,String.join(new List{ctd.Level_1__c, ctd.Level_2__c, ctd.Level_3__c}, '; ')));}返回结果；}}

Aura 组件 - JS 控制器部分

I need to build out a solution to create a search field on the new Case Type Data object in all 3 of the Level fields and populate based on selection.
Similar to SF Global Search I would like to type 2-3 characters in the text search field and it would find the matching text in the Level1-3 fields and when selected the Level 1-3 field would populate.
This is the apex class
public class PickListHandler {
@AuraEnabled
public static List<String> getLevel1(){
List<String> tempLst1 = new List<String>();
for(AggregateResult ar : [select Level_1__c,COUNT(id) from Case_Type_Data__c group by Level_1__c])
{
tempLst1.add(''+ar.get('Level_1__c'));
}
return tempLst1;
}
@AuraEnabled
public static List<String> getLevel2(string strName){
List<String> tempLst2 = new List<String>();
for(AggregateResult ar : [select Level_2__c,COUNT(id) from Case_Type_Data__c where Level_1__c=:strName group by Level_2__c])
{
tempLst2.add(''+ar.get('Level_2__c'));
}
return tempLst2;
}
@AuraEnabled
public static List<String> getLevel3(string strName1,string strName2){
List<String> tempLst3 = new List<String>();
for(AggregateResult ar : [select Level_3__c,COUNT(id) from Case_Type_Data__c where Level_1__c=:strName1 and Level_2__c=:strName2 group by Level_3__c])
{
tempLst3.add(''+ar.get('Level_3__c'));
}
return tempLst3;
}
@AuraEnabled
public static String savecasetype(string level1,string level2,string level3,string id){
string strMsg='successfull';
try{
ERT_Case_Type__c obj=new ERT_Case_Type__c();
Obj.Case__c = id;
System.debug('CASE = '+ Obj.Case__c);
Obj.Level_1__c=level1;
System.debug('Level1 = '+ Obj.Level_1__c);
Obj.Level_2__c=level2;
System.debug('Level2 = '+ Obj.Level_2__c);
Obj.Level_3__c=level3;
System.debug('Level3 = '+ Obj.Level_3__c);
Insert obj;
}
catch(Exception ex){
strMsg='error';
}
return strMsg;
}
}
This is the Picklist handler component

解决方案 You're asking for a lot, we wouldn't have your custom object. And this is old code, ui:inputSelect is deprecated for 1 year now. I'll try to help a bit but the whole thing needs your work too. And examples we can reproduce easily.
I'm going to cheat and use Philippe Ozil's ready component for the lookup/autocomplete thing.It means you'd have to save LookupSearchResult class, the whole aura component and 2 aura events in your org before reading below. That's some prep work but it's battle-tested :)
Apex class
public with sharing class Stack64129038 {
@AuraEnabled(cacheable=true)
public static List<LookupSearchResult> search(String searchTerm, List<String> selectedIds){
if(String.isBlank(searchTerm) || searchTerm.length() < 2){
return null;
}
String t = '%' + searchTerm + '%'; // decide how you want to search, "starts with", "includes" or what
List<Case_Type_Data__c> records = [SELECT Id, Name, Level_1__c, Level_2__c, Level_3__c
FROM Case_Type_Data__c
WHERE Level_1__c LIKE :t OR Level_2__c LIKE :t OR Level_3__c LIKE :t
ORDER BY Level_1__c, Level_2__c, Level_3__c
LIMIT 20];
/* You could also experiment with SOSL?
records = [FIND :('*' + searchTerm + '*') IN ALL FIELDS
RETURNING Case_Type_Data__c(Id, Name, Level_1__c, Level_2__c, Level_3__c)][0];
*/
List<LookupSearchResult> results = new List<LookupSearchResult>();
for(Case_Type_Data__c ctd : records){
results.add(new LookupSearchResult(ctd.Id, 'Case_Type_Data__c', 'standard:case_wrap_up', ctd.Name,
String.join(new List<String>{ctd.Level_1__c , ctd.Level_2__c, ctd.Level_3__c}, '; ')
));
}
return results;
}
}
