I am trying to disable button on a standard lightning component in Napili template. The lightning component is called ContactSupportForm and I want to disable the submit button on the load of that. I am unable to use document.getElementsByName , as it always returns nothing for any input.

Can any of you let me know if there is a better way to do it.

  • I suspect you'd need to customize the component by putting it in a wrapper and then only display the button when the fields contained valid content or something similar. I've not looked at the component's code to actually say.

unfortunatelly, this component is not publicly accessible. I have tried wrapping it in a custom component, however, since it is not documented, there is no way of knowing what attributes to reference in it.

You are better off creating a custom lightning component for your Contact Support Form. I would Recommend using the lightning:recordForm which will handle CRUD, FLS and does not need you to invoke an apex class to manage what fields to use in your form.

Basic usage example:

    <lightning:recordEditForm aura:id="recordEditForm"
                            onsubmit="{!c.handleRecordSubmit}"
                            objectApiName="Case">

    <lightning:inputField fieldName="Subject"/>
    <lightning:inputField fieldName="Description" />

<lightning:button aura:id="submit" type="submit" label="Create Case" class="slds-m-top_medium" disabled="true"/>

</lightning:recordEditForm>
