i want to prevent user from input whenever they put 0 using regular expression (regexp)

Question

I'm using this code for html:

<input pattern="/^[1-9]\d*$/g" id="num-input" type="number" min ="0" class="form-control number" placeholder="Input numbers here" aria-label="Input number here" aria-describedby="btn-generate">

and this is in my script.js file:

function numIntoUnits() { let num = $('#num-input').val() // let full_name = $("#register-full-name").val() console.log(num) }

it still shows the input numbers with zero

Your regex look overcomplicated. /^[1-9]+$/ should do just fine.

Furthermore, setting min to 1 instead of 0 should suffice.
