I'm making a form that includes two fields, Email and Re-Enter Email. I don't want the user to copy and paste the email id in the second field. I have to prevent right clicks on the re-enter field and/or the pasting functionality in that field. How do I achieve this? We have onPaste for ui input fields but not for lightning.

    Please don't do this. This is bad UX. It's bad enough if a field has to be entered twice. At least let your users paste content. – hsan Jan 18 at 13:59

    "Please confirm this question by retyping it a second time without copy-pasting." Your users hate retyping as much as you do. – zovits Jan 18 at 14:57

    Also note that people could still enter the email in the second field, and copy it to paste it in the first one – Rafalon Jan 18 at 15:20
  • I wouldn't even keep that field in my form if it was up to me. I fought against it. But that's what I've been 'instructed' to do. – vedant gupta Jan 21 at 6:28

You need to use HTML event attribute, example-


<lightning:input name="input1" label="Enter some text"  
    oncontextmenu="{! c.handleContext }" onpaste="{! c.handlePaste }"/>


handlePaste: function(component, event, helper) {

handleContext: function(component, event, helper) {
