Pattern Matching checking zipcode between range

Question

The data entered should be processed to check if the zip code is included in service area (This includes zip codes from 63121 to 69999).

This is what I have done I know I'm doing pattern matching wrong. Any help will be appreciated!

function validate() {
    var zipCode = document.getElementById("zip");
    var ok = zipCode.value.search(/^(6|9)\d{3,9}\d{1,9}\d{2,9}\d{1,9}$/);
    if (ok != 0) {
        alert("Sorry no service");
        zipCode.focus();
        zipCode.select();
        return false;
    } else
        return true;
}

HTML Part

<form name = "myForm" action = ""  >

        <table align = "center" bgcolor = "FF6600" cellspacing = "3" cellpadding = "4" border = "1" style="font-family:Comic Sans;vertical-align:center;">
        <caption style="background-color:#FFD700; text-align:left"> <font size="5" color="black">Check Coverage: </font></caption>
            <tr>
                <td class="info">First Name</td>
                <td><input type = "text" name = "first" class="textright">*</td>
            </tr>
            <tr>
                <td class="info">Phone Number</td>
                <td><input type  = "text"  name  = "phone" size="10" maxlength = "12" class="textright" >* (ddd-ddd-dddd)</td>
            </tr>
            <tr>
                <td class="info">Zip Code</td>
                <td><input type  = "text" id="zip" name = "zip1" size ="5" maxlength = "5" class="textright">* </td>
            </tr>
            <tr>
                <td class="size">* - Required Field</td>
                <td><input type = "button" class="but2" value ="Reset"><input type = "submit" class= "but2" onclick="validate()" value ="Check Availability" ></td>
            </tr>
        </table>
</form>

@Leptonator Not really a dupe, as this is asking about a very specific range of postcodes. — , Oct 30 '13 at 04:36
I've update the answer to meet your updated question. However as @MikeEdwards suggested: in future, you might want to either ask two questions, or scope the initial question better. — , Oct 30 '13 at 05:52

There is no need to use regex. Since all of the zipcodes you are looking at are all 5 digits long (with no leading zeroes), cast them as an integer and just check the zipcode is in the required range.

function validate() {
    var zipCodeField = document.getElementById("zip");
    var zipCode = parseInt(zipCodeField.value);
    if (!(63121 <= zipCode && zipCode <= 69999)) {
        alert("Sorry no service");
        zipCodeField.focus();
        zipCodeField.select();
        return false;
    } else {
        return true;
    }
}

With the update about it not working, I threw together this fiddle. The only thing you need to do is return the value of the validate() function, onsubmit of the form rather than onclick of the button.

@sean Well, there is no code that shows how this function is being called, so I don't know why that might be. But this should work as requested. – Oct 30 '13 at 04:53

If you need help getting event handlers to work, that's really a different question. Lego Stormtroopr answered the question you asked, you should mark it as answered and open a new question if necessary. – Mike Edwards Oct 30 '13 at 05:00

I saw that your requirement is linear..

var x=parseInt(zipcode)
if(zipcode<63121 and zipcode>69999){
alert("Sorry no service");
        zipCode.focus();
        zipCode.select();
        return false;
} 
else 
{
return true;
}
