會話在流星中設置值時發生克隆節點錯誤

Question

在我的流星項目會話中設置映射函數數組返回CloneNode錯誤！代碼是在這裏

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


}); 

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

和控制檯輸出這裏

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

錯誤控制檯：Uncaught TypeError: elem.cloneNode is not a function

Answer 1

我必須解決這個問題。

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); 
} 

結果在控制檯：

["category1", "category2"]
