Question

I want to use the same function if the user submit the #postcode-form or click on #show-results link. How can I do it without duplicate the function?

HTML

<form id="postcode-form">
    <input id="postcode" type="text" name="postcode" />
    <input type="submit" value="search" />
</form>
<a id="show-results" href="#">Show the results</a>​

JAVASCRIPT

$("#show-results").click(function(e){
        e.preventDefault();
        codeAddress(postcode);
});​

Answer 1

$("#postcode-form").submit(function(){
    //your submit function, validation, etc.
});

$("#show-results").click(function(e){
    $("#postcode-form").submit();
});
