Meteor中会话设置值时的CloneNode错误

Question

在我的Meteor Project会话中设置映射函数数组返回CloneNode错误！代码在这里

   var SubCategory = $(':checkbox[name=SubCategory]:checked').map(function() {


});

console.log(SubCategory);
Session.set( "subCategory", SubCategory);

和控制台输出

["category1", "category2", prevObject: jQuery.fn.init[2]]

控制台出错：Uncaught TypeError: elem.cloneNode is not a function

我已经解决了这个问题。

SubCategory(event){
let checked = event.target.checked;
let subcategory= [];
var SubCategory = $(':checkbox[name=SubCategory]:checked').map(function(value,index) {

   subcategory.push(index.value);

 });
Session.set( "subCategory", subcategory);
}

控制台中的结果：

["category1", "category2"]
