Prevent submit form when focus is on input

Question

I have a form with input fields and in the input field, I have click event but when i am pressing enter instead of calling javascript it submits the form.

<form id="frmPrice" method="post" action="script.php">
<input id="bar" name="bar" onclick="javascriptFunction1()" />
<input id="price" name="price" onclick="javascriptFunction2()" />
<input type="button" value="Send" onclick="submitform();" />
</form>
