script type="text/javascript">
function validate()
{
x=document.myForm
txt=x.myInput.value
if (txt=1 && txt<=5)
{
alert("The New York Times is deliverable to your area! ")
return true
}
else
{
alert("Unfortunately, the New York Times doesn't deliver to your area ")
return false
}
}
</script>


<form name="myForm" onsubmit="return validate()">

Enter Zipcode:
<input type="text" name="myInput">

<input type="submit" value="Check Zipcode">

</form>

I'm currently using this javascript to pull up a simple pop-up message stating if the entered zip code is correct or incorrect from a list of zipcodes I have.


Questions ::

1. How can I list my own numbers[list values] instead of using the numbers between 1 and 5 as stated on the script? I've tried editing it, but to no avail!

2. Is there anyway for the form to NOT submit the data, but just provide a pop-up window. Currently, the URL changes according to the value from the form (i'm going to embed this into a webpage later, so I don't want it to mess anything up).


Thanks so much for any help! !!!!

Do you mean like a drop down or mutiple select box?

I'm not that well versed in JavaScript, and there may be a more elegant solution, but try this:

[php]<script language="javascript">
<!--
function validate() {
var input_value = document.theform.theinput.value;
var good_values_list = new Array(123, 132, 213, 231, 312, 321);
var found = false;
var i;
for (i = 0; i < good_values_list.length; i++) {
if (good_values_list[i] == input_value) {
found = true;
break;
}
}
alert("In list: " + found);
return found;
}
-->
</script>[/php]

[php]<form action="WHATEVER.cgi" onsubmit="return validate();" name="theform">
<input type="text" name="theinput">
<input type="submit">
</form>[/php]

Replace your values in the array. When the onsubmit handler in the form returns false, the form action is canceled. If you want just the alert box whether the input is good or not, use onsubmit="validate();return false;"
