html5 onclick update table data - html

Question

I have a table that has js to allow me to sort the data. But I need to be able to change the data and have js still sort it when I click the header. I have a input box off to the side with a button. I am looking for a onclick way to change the table data from X to what is ever in that input box.
<td id="tabledata1">
1
</td>
I need to be able to change the "1" in that table data. I can not find the function code to effect that specific number. I am guessing it is something like this document.getElementById("tabledata1").style.color but instead of style.color there is something to reference table data.

Answer 1

It would look something like this
var cell = document.getElementById("tabledata1");
var button = document.getElementById("my-button");
var input = document.getElementById("my-input");
var par = document.getElementById("result");
button.addEventListener("click", function() {
cell.textContent = input.value;
});
<input id="my-input" type="text" />
<button id="my-button">Change Table Data</button>
<table>
<tr>
<td id="tabledata1">1</td>
</tr>
</table>
<p id="result"></p>
Breakdown
First query the document for the ids you want and store them into variables. You can then listen for the click event with the addEventListener function.
You can change the text of the table cell, by using the textContent property and setting it equal to the value of the input element.
