In some scenarios, we may need to call the standard approval process on click of a custom button. So in that case, we can have a lightning quick action in LWC similar to one in Aura components.
Step 1:
Create an action for an object. Lets say Opportunity. We need to specify the LWC component name. for create a LWC component and enter that name in Lightning Web Component field.
Step 2:
Add that action in the required page layout in the section as shown below:
So the configurations are done...
Step 3:
Let's do the code part
Open that already created LWC component and add this code.
LWC html file:
<template>
<lightning-quick-action-panel header="Submit for Approval">
<lightning-textarea label="Comments" value={comments} onchange={commentChange}
class="textAreaBody">
</lightning-textarea>
<div slot="footer">
<lightning-button variant="neutral" class="slds-m-left_x-small" label="Cancel"
onclick={closeAction}>
</lightning-button>
<lightning-button variant="brand" class="slds-m-left_x-small" label="Submit"
onclick={handleSubmitClick} >
</lightning-button>
</div>
</lightning-quick-action-panel>
</template>
------------------------------------------------
LWC Js file:
import { LightningElement,wire,track,api } from 'lwc';
import submitApproval from '@salesforce/apex/OppApproval.submitApproval';
import { CloseActionScreenEvent } from "lightning/actions";
import { CurrentPageReference } from 'lightning/navigation';
export default class OppApprovalLWC extends LightningElement {
@track comments;
@api recordId;
closeAction() {
this.dispatchEvent(new CloseActionScreenEvent());
}
@wire(CurrentPageReference)
getStateParameters(currentPageReference) {
if (currentPageReference) {
this.recordId = currentPageReference.state.recordId;
}
}
commentChange(event) {
this.comments = event.detail.value;
}
handleSubmitClick(event){
submitApproval({ oppId: this.recordId, comments: this.comments})
.then(result =>{
eval("$A.get('e.force:refreshView').fire();");
this.dispatchEvent(new CloseActionScreenEvent());
})
.catch(error =>{
});
}
}
