How to disable input text in input field?

There is a field input. How to make box you can enter only numbers? Know that you can mask, but I don't need to make a limit on the number of input digits not to do a mask of the placeholder when you click on the field itself.

How to solve this problem in pure js without jquery? Thank you all for the answers

the <script>
$(document).ready(function() {
$('[name=phone]').bind("change keyup input click", function() { // Specify the field name where you want to deny the contents of the text box
if (this.value.match(/[^0-9]/g)) {
this.value = this.value.replace(/[^0-9]/g, ");
