將html元素替換爲另一個

Question

此流星模板助手從mongodb集合中獲取其原始html，然後需要用預先創建的tr元素myTr替換特定的tr元素。這將是很好的使用JavaScript，但下面是使用jQuery這不是做這項工作。
怎麼辦？謝謝

Template.myHelper.helpers({ 
    info: function() { 
    let myTr = document.createElement('tr'); 
    //do things in myTr. 
    let data = myCollection.findOne({}); 
    let jObj = $($.parseHTML(data.rawHTML)); 
    jObj.find('td.myClass').each(function() { 
     if (this.textContent === "found it") { 
     this.parentElement.id = 'myId'; 
     jObj(this.parentElement).replaceWith(myTr); //<-- failed to repalce 
     } 
    }); 
    } 
}); 

Answer 1

那麼，你有很多變量的混合。看

jObj(this.parentElement).replaceWith(myTr); //<-- failed to repalce

jObj //that's jquery element 
this //that's html element 
this.parentElement //that's also html element 

jObj(this.parentElement) //what's this? supposed to be jquery object 

嘗試改變jObj(this.parentElement)到$(this.parentElement)，也將努力
