I need to do it for almost 10 input widget with same class ,but your code worked only for one input widget in same class so i tried replacing querySelector To querySelectorAll in javascript code  it says mobile.addEventListener is not a function       

               An suggestion .......   

                                THANKS IN ADVANCE 

Hi,

If you are using querySelectorAll then you need to use below code -

var all = document.querySelectorAll('.mobile');

Array.from({length: all.length}, (v, k) => k).forEach((index) => {
     let element = all.item(index);
element.addEventListener('input', restrictNumber);

});

function restrictNumber (e) {  

  var newValue = this.value.replace(new RegExp(/[^0-9\.]/g,'ig'), "");

  this.value = newValue;

}
