如何禁用 bootstrap 切换按钮

Question

我正在尝试禁用 bootstrap 切换按钮，但还没有成功

   <div class="toggle btn btn-default" disabled data-toggle="toggle" data-bind="toggle:isok(), css:{off:!isok()}">
                        <div class="toggle-group">
                            <label  class="btn btn-primary toggle-on">ON</label>
                            <label class="btn btn-default active toggle-off">OFF</label>
                            <span class="toggle-handle btn btn-default"></span>
                        </div>
                    </div>

我正在使用knockout绑定数据。我硬编码添加禁用属性，如您所见，但它显示为禁用，但我仍然可以打开或关闭它。

如何解决这个问题？

Answer 1

您将 disabled 属性硬编码到 div 元素。 div 无法禁用。将 div 更改为 button 它将起作用，请参见下面的示例，其中切换是手工制作的：

function Test() {
  var _this = this;
  _this.disabled = ko.observable();
  _this.active = ko.observable();

  _this.toggleActive = function() {
    _this.active(!_this.active());
  }

  _this.toggleDisable = function() {
    _this.disabled(!_this.disabled());
  }
}

ko.applyBindings(new Test());

<button type="button" class="btn btn-primary" aria-pressed="false" autocomplete="off" data-bind="css: {active: active}, click: toggleActive, enable: disabled">
      <span data-bind="visible: active">ON</span>
      <span data-bind="visible: !active()">OFF</span>
    </button>

<a href="#" data-bind="click: toggleDisable">toggle disable</a>
