<table>
<tr>
<td>foo1</td>
<td>bar1</td>
<td><input type="button" id="button1" onClick="get(this);"></td>
</tr>
<tr>
<td>foo2</td>
<td>bar2</td>
<td><input type="button" id="button2" onClick="get(this);"></td>
</tr>
</table>
Goal: To get buttons button1 and button2 to trigger the same function get() which should get the value of the first <td> in the same <tr> the button resides in. Which is, in this case: foo1 and foo2 respectively.
This is a rough outline of the function which should help understand what I'm trying to achieve-
function get(element){
alert(element.tr.first_td.innerHTML);
}
I realize there was a jQuery solution to a similar problem. But I do not understand jQuery well enough to translate it back to JavaScript. If it is possible at all using JavaScript, please show me how.
Crawl up the parentNode twice to get to the tableRow element. From there, access the first td from the HTMLCollection of cells, and get the innerHTML value:
function find( element ) {
alert( element.parentNode.parentNode.cells[0].innerHTML );
}
