Replacing the existing child table while appending a new one

Hey, I'm a beginner in the world of Javascript and currently working on creating a table using a select element with an array of dictionaries. The select element serves as a filter for the table values. However, my issue is that when I change the value of the select element to generate a new table, I want it to replace the previous one instead of adding to a long list of tables. Here's the snippet from my onchange event:

const filteredTable = document.getElementById("candidates_example");
const newFilteredTable = filteredTable.cloneNode(true);

removeRowsFromTable(newFilteredTable);
const filteredTbody = newFilteredTable.getElementsByTagName('tbody')[0];

const filterSelection = document.getElementById("filterSelect").value;
const selectFilter = filterCandidateBySkill(newCandidates, filterSelection)
addCandidatesToTable(filteredTbody,selectFilter);

document.body.appendChild(newFilteredTable);

I've attempted to search online for solutions but due to my limited knowledge in Javascript terminology, I am not sure what exactly to ask. Appreciate any guidance or assistance provided.

Answer №1

To swap out the existing table for a new one, you can utilize the replaceChild method:

replacedNode = parentNode.replaceChild(newChild, oldChild);

In your situation, this would look something like:

document.body.replaceChild(newFilteredTable, filteredTable);

Answer №2

Try swapping out appending for using .html() with jQuery, or alternatively updating the innerHTML of a specific element with document.getElementById('demo').innerHTML = tableVariable;
