将html元素替换为另一个

Question

此流星模板助手从mongodb集合中获取其原始html，然后需要用预先创建的tr元素myTr替换特定的tr元素。这将是很好的使用JavaScript，但下面是使用jQuery这不是做这项工作。
怎么办？谢谢

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

那么，你有很多变量的混合。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 

尝试改变jObj(this.parentElement)到$(this.parentElement)，也将努力
