Set or Modify Field Values in Onsubmit Event of lightning:recordeditform

Sometimes we can have a requirement to add or modify field values in onsubmit event of lightning:recordeditform. In below example, I’m creating “Lead” object record using lightning:recordeditform and in onsubmit event, I’m adding “Description” field value of “Lead” object.

Lightning Component:

<!--Sample.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable">
    
    <!--Component--> 
    <div class="slds-m-around--xx-large">
        <lightning:card title="Lead" iconName="standard:lead" class="slds-p-around_medium">
            <lightning:recordEditForm aura:id="leadCreateForm" objectApiName="Lead" onsubmit="{!c.handleOnSubmit}">
                <lightning:messages />
                
                <div class="slds-grid">
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="FirstName"></lightning:inputField>
                    </div>
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="LastName"></lightning:inputField>
                    </div>
                </div>
                
                <div class="slds-grid">
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="Email"></lightning:inputField>
                    </div>
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="Phone"></lightning:inputField>
                    </div>
                </div>
                
                <div class="slds-grid">
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="Company"></lightning:inputField>
                    </div>
                </div>
                
                <lightning:button type="submit" label="Save" variant="brand"/>
            </lightning:recordEditForm>
        </lightning:card>
    </div>
</aura:component>

Lightning JS Controller:

({
    handleOnSubmit : function(component, event, helper) {
        event.preventDefault(); //Prevent default submit
        var eventFields = event.getParam("fields"); //get the fields
        eventFields["Description"] = 'Lead was created from Lightning RecordEditForm'; //Add Description field Value
        component.find('leadCreateForm').submit(eventFields); //Submit Form
    }
})

Get lightning:recordeditform Field Values in onsuccess Event

Sometimes we can have a requirement to get field values, record Id, record type Id, child relationships information in onsuccess event of lightning:recordeditform. In below example, I’m creating “Lead” object record using lightning:recordeditform and after successfully saving the record, getting the field values in onsuccess event.

Lightning Component:

<!--Sample.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable">

            <lightning:recordEditForm aura:id="leadCreateForm" objectApiName="Lead" onsuccess="{!c.handleOnSuccess}">
                <lightning:messages />
                
                <div class="slds-grid">
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">

                    </div>
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">

        var childRelationships = param.response.childRelationships; //get child relationship info
        var recordTypeInfo = param.response.recordTypeInfo; //get record type info
        var recordId = param.response.id; //get record id
        
        console.log('Param - ' + JSON.stringify(param)); 
        console.log('Fields - ' + JSON.stringify(fields)); 
        console.log('Child Relationship - ' + JSON.stringify(childRelationships)); 
        console.log('Record Type Info - ' + JSON.stringify(recordTypeInfo)); 
        console.log('Record Id - ' + JSON.stringify(recordId)); 
        
        //get Record Edit Form Field Values
        console.log('FirstName - ' + fields.FirstName.value);
        console.log('LastName - ' + fields.LastName.value);
        console.log('Email - ' + fields.Email.value);
        console.log('Phone - ' + fields.Phone.value);
        console.log('Company - ' + fields.Company.value);
    }
})

Get Record Id From lightning:recordeditform in onsuccess Event

Craete Record Using Lightning Data Service

Lightning Data Service (LDS) is to serve as the data layer for Lightning. It is similar like Standard Controllers in Visualforce Page.

Advantages of Lightning Data Service:

  • Lightning Data Service allows to load, create, edit, or delete a record without requiring Apex code and SOQL query.
  • Lightning Data Service handles sharing rules and field-level security.
  • Records loaded in Lightning Data Service are cashed and shared across all components.
  • When one component updates a record, the other component using it are notified.
  • Lightning Data Service supports offline in Salesforce1.

In below example I’m creating Lead object record using Lightning Data Service. By using the new base lightning component lightning:recordEditForm, we can create and edit records, without custom Javascript and Apex code.

Lightning Component:

<!--Sample.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable">
    
    <!--Component--> 
    
<div class="slds-m-around--xx-large">
        <lightning:card title="Lead" iconName="standard:lead" class="slds-p-around_medium">
            <lightning:recordEditForm aura:id="leadCreateForm" objectApiName="Lead" onsuccess="{!c.handleOnSuccess}">
                <lightning:messages />
                
                
<div class="slds-grid">
                    
<div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="FirstName"></lightning:inputField>
                    </div>

                    
<div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="LastName"></lightning:inputField>
                    </div>

                </div>

            </lightning:recordEditForm>
        </lightning:card>
    </div>

</aura:component>

Lightning JS Controller:

({
    handleOnSuccess : function(component, event, helper) {
        var toastEvent = $A.get("e.force:showToast");
        toastEvent.setParams({
            "title": "Success!",
            "message": "The record has been created successfully.",
            "type": "success",
            "mode": "pester"
        });
        toastEvent.fire();
        $A.get("e.force:refreshView").fire();
    }
})
