Disable input at click jquery

Question

Through jQuery I would like to find a way to disable an input ONLY IF EMPTY on_ click of a button below.

This is the input:

<input type="text" min="0" id="toolset-maps-distance-center" name="toolset_maps_distance_center" class="form-control js-toolset-maps-distance-center js-wpv-filter-trigger" value="" required="" placeholder="Inserisci una posizione" autocomplete="off">

This is the button:

<button type="submit" class="wpv-submit-trigger js-wpv-submit-trigger btn">Recherche</button>

This is my jQuery:

jQuery('.wpv-submit-trigger.js-wpv-submit-trigger.btn').click(function(){
  jQuery('#toolset-maps-distance-center').prop('disabled', true);
});

The result in the console is:

Uncaught SyntaxError: Invalid or unexpected token

Is true\false how it is in your code? It should be either true or false. — steven35

Or try using attr('diabled', 'disabled') instead of prop — Code_Ninja

$('.wpv-submit-trigger.js-wpv-submit-trigger.btn').click(function() {
    //check if input is empty
    var ifInputIsEmpty = $('#toolset-maps-distance-center').val() === '';
    //set disabled attribute according to ifInputIsEmpty
    $('#toolset-maps-distance-center').prop('disabled', ifInputIsEmpty);
});

please try this. Check the value of input field and if it is empty, just disable it.

jQuery('.wpv-submit-trigger.js-wpv-submit-trigger.btn').click(function(){
  var inputValue=jQuery('#toolset-maps-distance-center').val();
    if(!inputValue)
    {        
      jQuery('#toolset-maps-distance-center').attr('disabled','true');
    }
});

As per i understand, you want the submit button to disabled when input is empty. For that try this:

if ($.trim($('.kind').val()).length === 0){
  $('.kind').prop('disabled', true);
}

<input class="kind" id="name" name="name" type="text" placeholder="Kind">

    <button class="submit" >Submit</button>
