Custom record search and delete functionality in lightning component

Post Views: 33

Hey guys, In this post we are going to learn that how we can create a custom record search and delete record functionality in Salesforce lightning components.

In this example we will search Custom sObject records with an lightning input field.

Files we used in this post example:-

File Name	File Type	Description
studentInfoApp.app	Lightning Component Application	It is used for preview the component on browser.
studentInfoCmp.cmp	Lightning Component	It is used for Search Inpur field and Record User InterfaceTable.
studentInfoCmpController.js	JavaScript Controller File	It is used for search record and deleter record functionality.
studentInfoCmpHelper.js	JavaScript Helper File	Helper function called in the Javascript controller on Init function.
studentInfoCtrl.apxc	Apex Class Controller	It is used for For Search and delete record from database server
Custom Object:- student_info__c Custom Object Fields:- student_first_name__c student_last_name__c student_phone__c	Custom Object and their fields	Custom object like database and custom fields are column of data table.

Step 1:- Create Lightning Application : studentInfoApp.app

From Developer Console >> File >> New >> Lightning Application

studentInfoApp.app [Component Application File]

   <aura:application extends="force:slds">	
       <c:studentInfoCmp />
   </aura:application>

<aura:application extends="force:slds">

<c:studentInfoCmp />

</aura:application>

Step 2:- Create Lightning Component : studentInfoCmp.cmp

From Developer Console >> File >> New >> Lightning Component

studentInfoCmp.cmp [Lightning Component File]

   <aura:component controller="studentInfoCtrl" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >    
    <aura:attribute name="studentInfoAc" type="student_info__c" default="{'sobjectType': 'student_info__c'}"/>    
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>    
    <aura:attribute name="studentItrt" type="student_info__c[]"/> 
    
  <div class="slds slds-p-horizontal--medium">  
    <div class="slds-large-size--3-of-12 slds-m-bottom--medium slds-p-around--small">
        Search Student Name <ui:inputText aura:id="searchFld" value="" class="slds-input" keyup="{!c.searchRow}" updateOn="keyup" placeholder="Search Name..."/>
    </div>    
    
   <div style="width:40%;"> 
    <table class="slds-table slds-table--bordered">        
        <tr style="background-color:#eee;">
            <th>First Name</th>
            <th>Last Name</th>
            <th>Phone</th>  
            <th></th>
        </tr>
        
        <aura:iteration items="{!v.studentItrt}" var="studentItem" >
            <tr>
                <td>{!studentItem.student_first_name__c} </td>
                <td>{!studentItem.student_last_name__c}</td>
                <td>{!studentItem.student_phone__c}</td>
                <td><span><a style="color:#ff0000; font-weight:bold;" id="{!studentItem.Id}" onclick="{!c.deleteRow}" title="Delete">X</a></span></td>
            </tr>
        </aura:iteration>      
        
        
    </table>
   </div> 
  </div>  
 </aura:component>

<aura:component controller="studentInfoCtrl" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >

<aura:attribute name="studentInfoAc" type="student_info__c" default="{'sobjectType': 'student_info__c'}"/>

<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

<aura:attribute name="studentItrt" type="student_info__c[]"/>

Search Student Name <ui:inputText aura:id="searchFld" value="" class="slds-input" keyup="{!c.searchRow}" updateOn="keyup" placeholder="Search Name..."/>

</div>

<th>First Name</th>

<th>Phone</th>

</tr>

<aura:iteration items="{!v.studentItrt}" var="studentItem" >

<tr>

<td>{!studentItem.student_first_name__c} </td>

<td>{!studentItem.student_last_name__c}</td>

<td>{!studentItem.student_phone__c}</td>

</tr>

</aura:iteration>

</table>

</div>

</aura:component>

Step 3:- Create Lightning Component : JavaScript Controller

From Developer Console >> File >> New >> Lightning Component >> JavaScript Controller

studentInfoCmpController.js [JavaScript Controller]

      ({
    
    doInit: function(component, event, helper) {        
        helper.loadDetails(component, event);
        
    },
    
    
    submitStudentInfo : function(component, event, helper) {
        var action = component.get('c.getStudent');
        var postData =  component.get('v.studentInfoAc');        
        console.log(':: postData ::: '+JSON.stringify(postData));
        console.log(':: postData Name :: '+postData.student_first_name__c);
        action.setParams({"insertStudent": postData});   
        
        action.setCallback(this, function(response) {            
            var state = response.getState();  
            if (state === "SUCCESS") {                
                var stringItems = response.getReturnValue();
                component.set("v.studentItrt",stringItems);
                component.set('v.studentInfoAc.student_first_name__c', ""); 
                component.set('v.studentInfoAc.student_last_name__c', "");
               component.set('v.studentInfoAc.student_phone__c', ""); 
            }
        }); 
        
        $A.enqueueAction(action);
    },
    
    
    deleteRow : function(component, event, helper) {
	   var thisObj = event.target.id;        
       var action = component.get('c.deleteRowCtrl');
        action.setParams({'deleteRowId':thisObj});
        action.setCallback(this, function(response){
            var state = response.getState();
            if(state == 'SUCCESS'){
                var getReturnRow =  response.getReturnValue();
                component.set('v.studentItrt', getReturnRow); 
                //component.set('v.studentInfoAc', []);
                alert('Record deleted successfully');
            }
        });
        $A.enqueueAction(action);
	},
    
    
    searchRow : function(component, event, helper) {	
        var searchFld = component.find('searchFld').get("v.value");
        
       var action = component.get('c.searchData');
        action.setParams({'searchKey':searchFld});
        action.setCallback(this, function(response){
            var state = response.getState();
            if(state == 'SUCCESS'){
                var getReturnRow =  response.getReturnValue();
                component.set('v.studentItrt', getReturnRow);
            }
            
        });
        $A.enqueueAction(action);
	},
            
})

({

doInit: function(component, event, helper) {

helper.loadDetails(component, event);

submitStudentInfo : function(component, event, helper) {

var action = component.get('c.getStudent');

var postData = component.get('v.studentInfoAc');

console.log(':: postData ::: '+JSON.stringify(postData));

console.log(':: postData Name :: '+postData.student_first_name__c);

action.setParams({"insertStudent": postData});

action.setCallback(this, function(response) {

var state = response.getState();

if (state === "SUCCESS") {

var stringItems = response.getReturnValue();

component.set("v.studentItrt",stringItems);

component.set('v.studentInfoAc.student_first_name__c', "");

component.set('v.studentInfoAc.student_last_name__c', "");

component.set('v.studentInfoAc.student_phone__c', "");

}

});

$A.enqueueAction(action);

deleteRow : function(component, event, helper) {

var thisObj = event.target.id;

var action = component.get('c.deleteRowCtrl');

action.setParams({'deleteRowId':thisObj});

action.setCallback(this, function(response){

var state = response.getState();

if(state == 'SUCCESS'){

var getReturnRow = response.getReturnValue();

component.set('v.studentItrt', getReturnRow);

//component.set('v.studentInfoAc', []);

alert('Record deleted successfully');

}

});

$A.enqueueAction(action);

searchRow : function(component, event, helper) {

var searchFld = component.find('searchFld').get("v.value");

var action = component.get('c.searchData');

action.setParams({'searchKey':searchFld});

action.setCallback(this, function(response){

var state = response.getState();

if(state == 'SUCCESS'){

var getReturnRow = response.getReturnValue();

component.set('v.studentItrt', getReturnRow);

}

});

$A.enqueueAction(action);

})

Step 4:- Create Lightning Component : studentInfoCmpHelper.js

From Developer Console >> File >> New >> Lightning Component >> JavaScript Helper

studentInfoCmpHelper.js [JavaScript Helper File]

      ({
	    
    loadDetails: function(component, event) {
       var studentItrt =   component.get('v.studentItrt');
       var action =   component.get('c.loadStudentInfo');
        action.setCallback(this, function(response){
          var state = response.getState();
        if(state == 'SUCCESS'){
            var getResponse = response.getReturnValue();
            component.set('v.studentItrt',getResponse);
            console.log('studentItrt::' + studentItrt);
          }
        });
        
      $A.enqueueAction(action);
        
    },
    
    })

({

loadDetails: function(component, event) {

var studentItrt = component.get('v.studentItrt');

var action = component.get('c.loadStudentInfo');

action.setCallback(this, function(response){

var state = response.getState();

if(state == 'SUCCESS'){

var getResponse = response.getReturnValue();

component.set('v.studentItrt',getResponse);

console.log('studentItrt::' + studentItrt);

}

});

$A.enqueueAction(action);

})
