Restricting the use of some characters in an InputField?

Question

Unity

How to make it so that the player can enter only one word in the InputField, and cannot use punctuation marks?

Answer 1

I don’t know, maybe it was moved somewhere with the new UIElements and renamed, but the general principle is to look at the documentation
https://docs.unity3d.com/2019.1/Documentation/Scri... with a
script to check and cut off unnecessary characters.

Answer 2

Intercept changes to the input field and remove unnecessary characters from there.

Answer 3

The simplest (codes of letters in the asci table):

<script language="JavaScript" type="text/javascript">
$(document).ready(function(){
$('.prices').keypress(function(e) {
if (!(e.which==8 || e.which==44 ||e.which==45 ||e.which==46 ||(e.which>47 && e.which<58))) return false;
});
});
</script>

Entering numbers only:

<input type="text" id="input"/>
<script>
 input = document.getElementById('input')
 input.onkeyup = function(){this.value = this.value.replace(/[^0-9\.]/g,'')}
</script>

And here is a brilliant solution (though not mine):
it makes it possible to insert one dot or one comma and numbers

<script>
function validate(inp) {
    inp.value = inp.value.replace(/[^\d,.]*/g, '')
                         .replace(/([,.])[,.]+/g, '$1')
                         .replace(/^[^\d]*(\d+([.,]\d{0,5})?).*$/g, '$1');
}

</script>
