用另一个替换html元素

Question

This Meteor template helper gets its raw html from mongodb collection, it then needs to replace a specific tr element with a pre created tr element myTr . It would be nice to use javascript but the below is using jQuery which is not doing the job.
How can it be done? Thanks

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
      }
    });
  }
});

Well, you have beatifull mix of variables. Look

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

try changing jObj(this.parentElement) to $(this.parentElement) and it will work
