使用 Office Fabric UIMessageBanner组件时遇到问题。为什么我可以实例化一个由 jQuery 和 jQuery 返回的元素document.querySelector，ChoiceFieldGroup但只document.querySelector适用于MessageBanner？

这是文件test.html：

$(document).ready(function () {
    //This works:
    var $ChoiceFieldGroupElements = $(".ms-ChoiceFieldGroup");
    //This also works:
    //var $ChoiceFieldGroupElements = document.querySelector(".ms-ChoiceFieldGroup");

    //This works:
    var $mb = document.querySelector('.ms-MessageBanner');
    //This doesn't work:
    //var $mb = $('.ms-MessageBanner');

    // Just the components' initialization
    for (var i = 0; i < $ChoiceFieldGroupElements.length; i++) {
        new fabric["ChoiceFieldGroup"]($ChoiceFieldGroupElements[i]);
    }
  var MessageBanner =   new fabric["MessageBanner"]($mb);
});

这是文件test.html：

事实证明，我将 jQuery 元素与 Fabric 元素混合在一起。

错误发生在 Fabric 对象的初始化中，而不是选择器中。

如果您的元素是 HTML，则使用以下语法构建他的组件：

new fabric['ComponentName'](document.querySelector('.class-name'));

但是，如果您有一个 jQuery 对象，则必须使用以下方法将原始 HTML 传递给 Fabric 方法[0]：

new fabric['ComponentName']($('.class-name')[0]);
