Replace a character in a string?

    I've got a form that redirects a user to a dynamic url based on the word they enter. e.g they enter 'banana' and the form takes them to www.domain.com/banana

    The problem is when somebody enters a word with a dot e.g "banana.apple".
    Then I get a 404.

    So I want to replace '.' with '_dot_' or something BEFORE the form is submitted. How do I do it?

    <form name="openlocation" action="">
<input type="text" name="href" value="" />
<input type="button" value="Go!" onClick="location.href=document.openlocation.href.value;" />
</form>
    Code (markup):

    Or course, if there's a sexy htaccess way to do this, then please tell me :)

    I think that will only replace the first dot, so "apple.pear.banana." would become "apple_dot_pear.banana."

    What you want is:

    value.replace(/\./g, "_dot_");

    to make it "apple_dot_pear_dot_banana_dot_"
