Can I replace string with a variable in innerhtml?

[Guest]

Hi,

I have the following script:

function change2(e)
{
var userInput = document.getElementById(e).innerHTML;
userInput++;
document.getElementById(e).innerHTML = userInput;
}
</script>

being called via:

echo "<a href=\"#\"><img src=\"./../Up.JPG\" border=\"0\" onclick=\"change2('".$idkey."');\"></a>";
echo " ".$num_rows1."</form>";

I basically want 'e' to be dynamic accepting the id passed into it.

Thanks in advance.
