Hi:
I have a form input field that need to be validated with at least 5 character and must contain one letter and 1 number. But it is not working. Below is my code. Please help. Thank you.
[CODE]
<form id=”search_mini_form” action=”/catalogsearch/result/” method=”get” target=”frame1″>
<div class=”form-search”><label for=”search”>Search:</label>
<input id=”search” class=”input-text” type=”text” name=”q” value=”” />
<button class=”button” title=”Search” type=”submit” ><span><span>Search</span></span></button>
<script type=”text/javascript”>
<!–
function checkserial(){
var reg = /^.*(?=.{4,10})(?=.*d)(?=.*[a-zA-Z]).*$/i //regular expression defining a 5 digit number
if (document.search_mini_form.q.value.test(reg)==-1) //if match failed
alert(“Please enter a valid serial number.”)
}
–>
</script>
</form>
