Unobtrusive Script With Parameters?

I have a PHP page that dynamically generates table rows with input fields. A sample row looks like:

Code:
<tr id="row1">
<td><input type="button" name="remove_row1" id="remove_row1" value="X" /></td>
</tr>

I have a JavaScript function that I am attempting to attach to each of the input buttons:

Code:
// get all the input elements
var inputs = document.getElementsByTagName('input');
var delete_regex = new RegExp('remove_row');[code]...

But I would like to give it a parameter

Code: inputs[i].onclick = delete_row('row' + inputs[i].id.replace('remove_row', ''));

But doing the above just executes the function. What is the best way to do this?
