How To Grab The Values From An HTML Table's Cells Using JavaScript

August 31, 2022 Post a Comment

I'm trying to grab the cell values from an HTML table so that I can save them into a MySQL table via a call to PHP. I'd like to use JavaScript rather than jQuery. I'm giving each

Solution 1:

Use the innerText property for the td. Here's a fiddle that shows how to use it.

HTML

<table>
    <tr>
        <td id="1">Bla</td>
        <td id="2"><input id="txt" />Ble</td>
    </tr>
</table>

JavaScript

var td = document.getElementById('1');
alert(td.innerText);
var td2 = document.getElementById('2');
alert(td2.innerText);

How to grab cell values from a table?

Update to address Elliots comment

See how to grab the cell value (innerText and data-value) in my new demo

In the table the attribute data-value is used to store some data (2B, 3C,..).

<table id="t2">    
  <thead>
   <tr id="tr1"><th>Student Name<th>Course</tr> 
  </thead>
  <tbody>
    <tr id="tr2"><td data-value="2B">Bert2  <td>Economics  </tr>
    <tr id="tr3"><td data-value="3C">Clyde3 <td>Chemics    </tr>
    <tr id="tr4"><td data-value="4D">       <td>Digital Art</tr>
    <tr id="tr5"><td data-value="5E">Ernest <td>Ecmoplasma </tr>
  </tbody>
</table>

With jQuery and the right selector you can iterate over each cell:

function eachCell(){
    var cellInnerText = [];
    var cellValue = [];
    var out = document.getElementById("out");
    var out2 = document.getElementById("out2");
    // iterate over each row in table with id t2 in the table-body (tbody)
    $('#t2 tbody tr').each(function(index){     
       // copy the text into an array
       cellInnerText.push($(":first-child", $(this)).text());
       //copy the data-value into an array
       cellValue.push($(":first-child", $(this)).attr('data-value'));
    });
    // show content of both arrays
    out.innerHTML = cellInnerText.join(" | ");
    out2.innerHTML = cellValue.join(" | "); 
}

Solution 3:

Alert the innerHTML of the first cell in the table's first row

<!DOCTYPE html>
<html>
<head>
<style>
table, td {
    border: 1px solid black;
}
</style>
</head>
<body>

<p>Click the button to alert the innerHTML of the first cell (td element with index 0) in the table's first row.</p>

<table id="myTable">
  <tr>
    <td>Row1 cell1</td>
    <td>Row1 cell2</td>
  </tr>
  <tr>
    <td>Row2 cell1</td>
    <td>Row2 cell2</td>
  </tr>
  <tr>
    <td>Row3 cell1</td>
    <td>Row3 cell2</td>
  </tr>
</table>
<br> 

<button onclick="myFunction()">Try it</button>

<script>
function myFunction() {
    alert(document.getElementById("myTable").rows[0].cells[0].innerHTML);
}
</script>

</body>
</html>

Solution 4:

Place IDs on Your inputs with some pattern. for example <input type="text" id="input_0_0" name="whatever" /> where 0 is row and second 0 is column and then instead your alert type

v = document.getElementById('input_'+row+'_'+col).value;
