How to check multiple input fields for text?

Question

Node.js

There are lines like this:

function check() {
  if ($('#zagol').val() != '')
    $('#zag').removeAttr('disabled');
  else
    $('#zag').attr('disabled','disable');
}

The script checks the zagol field for text and activates the button if text is entered.
It is necessary to redo the script so that it checks several fields. For example, there is also a #users field and a separate button for this field.

Answer 1

You need to update the plugin to gulp-refresh .

Answer 2

In your case, it's better to refuse selection by id in favor of class .
If the button, then you can do this.<input type="submit">

<form>
     <input type="text" class="checkme" value="zagol">
     <!-- Другие элементы формы -->
     <input type="submit">
</form>
<form>
     <input type="text" class="checkme" value="users">
     <!-- Другие элементы формы -->
     <input type="submit">
</form>

Can you do it like this

function check(){
  if ($(this).val() !== '') $(this).parent().find('input[type="submit"]').removeAttr("disabled");
  else $(this).parent().find('input[type="submit"]').attr('disabled', true);
}
$(".checkme").change(check);

If the markup goes in pairs

<input type="text" class="checkme">
<button>#Загол</button>
<!-- Другие элементы -->
<input type="text" class="checkme">
<button>#Юзеры</button>

then you can change the check function like this

function check(){
  if ($(this).val() !== '') $(this).next('button').removeAttr("disabled");
  else $(this).next('button').attr('disabled', true);
}
$(".checkme").change(check);

Answer 3

Look to the side
$('form').find('input').each(.....);
