Disable copy paste in textbox

Question

I have my input Textbox like below. User should not be allowed to perform copy paste in the Textbox. But somehow my code is not working. Is there any other approach?

<input type="text" class="form-control"  id="startTextbox1" appOnlynumber onkeypress='validate(event)' onCopy="return false" onDrag="return false" onDrop="return false" onPaste="return false" formControlName="startTextbox1">

I have also written custom directive like it specified in below link but its not working.

Any suggestions please?

Answer 1

Not sure this is what you are going for, but perhaps this prior question gives you some place to start:

Disable pasting text into HTML form

Answer 2

I know you can do this with JS / jQuery

$(document).ready(function(){
   $('#startTextbox1').on("cut copy paste",function(e) {
      e.preventDefault();
   });
});

Hope that can help

Answer 3

Simply do this

 <Input onPaste="return false" onCopy="return false" placeholder="Try to copy or paste here" />
