I am attempting to develop an input field for entering a PIN. I would like the PIN to be masked on mobile devices, similar to how passwords are obscured in password input fields. I came across a suggestion on stackoverflow regarding this, but unfortunately, none of the solutions have been successful thus far.
<input type="password" name="PIN" pattern="[0-9]*" inputmode="numeric" style="-webkit-text-security: disc;" required>
Is there a method to accomplish this task?
To achieve this effect, CSS is the way to go
#password{
-webkit-text-security: disc;
-moz-text-security:circle;
text-security:circle;
}
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
} <input type="number" id="password" pattern="[0-9]*" >There are multiple ways to achieve this, but using CSS is the simplest approach. I hope this solution works for you :)
You might want to consider implementing a solution using JavaScript
let phoneNumberInput = document.getElementById('phone');
phoneNumberInput.oninput = function(){
// check if field is empty
if(!this.value) return;
// check if input is not numeric
let isNumeric = this.value[this.value.length - 1].match(/[0-9]/g);
if(!isNumeric) this.value = this.value.substring(0, this.value.length - 1);
}<input id="phone" type="text">Consider changing type="password" to type="number". It seems that the password input type may be preventing the numeric keyboard from appearing on mobile devices. Although this solution may only be effective on webkit browsers, it is worth a try since webkit is widely utilized in mobile browsers.
<input type="number" pattern="[0-9]*" inputmode="numeric" style="-webkit-text-security:disc;">In addition, there is no foolproof method to guarantee both password and numeric input on mobile devices without resorting to javascript.
By selecting this choice, a numeric keyboard will appear to input only numbers.
<input inputmode="numeric" type="password" oninput="this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1');" />
