空输入的JS验证指标

Question

我需要它，以便.edit :input 启用时，.indicator仅在addClass('animate');为空时才会收到input。

如果.edit :input 被驱散，则每.indicator收到removeClass('animate');并消失。

我很接近，但是在点击了.edit-toggle并在input中添加和删除了一些文字后，.animate似乎在没有任何指示的情况下添加/删除了自己。

$(".edit-toggle").prop("checked", true);
$(".edit :input").attr("disabled", true);
$('.edit-toggle').on('change', function() {
    var idInput = $(this).data('input');
    var inputEle = $('.' + idInput);
    var indicator = inputEle.next();
    if ($(this).is(":checked")) {
      inputEle.attr("disabled", true);
    } else {
      if (inputEle.val() == '' && inputEle.prop('required')) {
        indicator.addClass('animate');
      } else {
        indicator.removeClass('animate');
      }
      inputEle.removeAttr("disabled");
    }
  }

);
$(".edit :input").on('keyup', function() {
    var $this = $(this);
    var $indicator = $('.indicator', $this.parent());
    if ($this.val() == '' && $this.prop('required')) {
      $indicator.addClass('animate');
    } else {
      $indicator.removeClass('animate');
    }
  }

);

由于input和.indicator是列表，因此您需要使用.each来覆盖数组中的所有元素

$(".edit-toggle").prop("checked", true);
$(".edit :input").attr("disabled", true);
$('.edit-toggle').on('change', function() {
    var idInput = $(this).data('input');
    var inputEle = $('.' + idInput);
    var toggleInput = $(this);
    inputEle.each(function() {
      var indicator = $(this).next();
      if (toggleInput.is(":checked")) {
        $(this).attr("disabled", true);
      } else {
        if ($(this).val() == '' && $(this).prop('required')) {
          indicator.addClass('animate');
        } else {
          indicator.removeClass('animate');
        }
        $(this).removeAttr("disabled");
      }
    })
    
  }

);
$(".edit :input").on('keyup', function() {
    var $this = $(this);
    var $indicator = $('.indicator', $this.parent());
    if ($this.val() == '' && $this.prop('required')) {
      $indicator.addClass('animate');
    } else {
      $indicator.removeClass('animate');
    }
  }

);
