Onclick="Enter" with my code

I'd like to add the "enter" function to this... anyone know how?

<form><input name='search_term'>&nbsp;&nbsp;&nbsp;&nbsp;<input
type='button' value="Search" onclick=
"javascript:find_text(search_term.value);"></form>

Code (markup):

Here's the code....

<script type="text/javascript">
function find_text(txt) {
var rng = document.body.createTextRange()
if (rng.findText(txt)) {
rng.select();
}
}
</script>

 

make your button as type=submit, and the enter key will start working.

 

Thank you... I found another search option!
