The function document.getElementById(...) is failing to retrieve the text data from the table as expected

Greetings fellow HTML and JavaScript novice!

I've got a table with input cells in the bottom row:

<table class="convtbl" id="table1">
        <tr>
            <td>Distance 1 (in miles)</td>
            <td>Time 1 (hh:mm:ss)</td>
            <td>Distance 2 (in miles)</td>
            <td>Time 2 (hh:mm:ss)</td> 
       </tr>
       <tr>
           <td><input type="text"/></td>
           <td><input type="text"/></td>
           <td><input type="text"/></td>
           <td><input type="text"/></td>
       </tr>
   </table>

I'm working on a function to modify the input cell values. I haven't completed it yet, but during a trial run, I used an alert to check if text was properly extracted from column 1. Surprisingly, the alert displayed undefined. Any thoughts on why this might be happening?

function tdconvert() {
       var d1 = document.getElementById("table1").rows.item(1).cells.item(0).firstChild.textConent;
       var t1 = document.getElementById("table1").rows.item(1).cells.item(1).firstChild.textConent;
       var d2 = document.getElementById("table1").rows.item(1).cells.item(2).firstChild.textConent;
       var t2 = document.getElementById("table1").rows.item(1).cells.item(3).firstChild.textConent;
       alert(d1);
   }

Answer №1

It looks like you may have confused the properties here. Instead of textConent, did you mean to use element.value? If your intention is to retrieve the text content, it should be textContent.

var d1 = document.getElementById("table1").rows.item(1).cells.item(0).firstChild.value;

Answer №2

When you're trying to access the textContent attribute of a textbox, it might return undefined. Instead, consider using the value attribute of the textbox.

An example: document.getElementById("table1").rows.item(1).cells.item(0).firstChild.value;

I have tested this method and can confirm that it works.
