var empty   true     input type  quot text quot     each function        if    this  val       quot  quot           empty   false        return false            This should look all the input and set the empty var to false  if at least one is not empty  EDIT  To match the OP edit request  this can be used to filter input based on name substring     input name   quot denominationcomune  quot     each

You could do it like this    bool areFieldEmpty   YES    Label to leave the loops outer loop     For each input  except of submit  in your form    form input type  submit    each function         If the field s empty    if   this  val                       Mark it       areFieldEmpty   NO          Then leave all the loops       break outer loop              Then test your bool

Define a helper function like this  function checkWhitespace inputString        let stringArray   inputString split            let output   true       for  let el of stringArray           if  el                   output false                       return output      Then check your input field value by passing through as an argument  If function returns true  that means value is only white space   As an example  let inputValue       firstName   val    if checkWhitespace inputValue          Show Warnings or return warnings  else           Block of code-probably store input value into database
