[jQuery] Form validation using the validate plugin
Rather than write my own validation I thought i would use JQuery
instead however i'm not finding this easy either. I have a few
questions which I hope someone can answer. Firstly, the error messages
are only appearing when I click submit. How can I get them to appear
after exiting each field? Here's my code for validation.
Code:
$(document).ready(function(){
$("#orderForm").validate({
rules: {
shipFirstName: {
required: true,
},
shipFamilyName: {
required: true,
},
shipPhoneNumber: {
required: true,
},
shipStreetName: {
required: true,
},
shipCity: {
required: true,
},
billEmailAddress: {
required: true,
},
billPhoneNumber: {
required: true,
},
billCardNumber: {
required: true,
},
billCardType: {
required: true,
},
}, //end of rules
}); // end of validae
}); //end of function
This is my HTML code for the form. I won't show the styling but I have
changed it to display a red font.
Code:
<form id="orderForm" method="post" action="x">
<table id="formTable" cellpadding="5">
<tr>
<td>
<h3>Shipping and Billing Information</h3>
</td>
<td> </td>
</tr>
<tr>
<td><label for="shipFirstname">First Name</label></td>
<td><input id="shipFirstName" type="text"
name="shipFirstName" maxlength=
"30" /></td>
</tr>
<tr>
<td><label for="shipFamilyName">Surname</label></td>
<td><input id="shipFamilyName" type="text"
name="shipFamilyName" maxlength="30" /></td>
</tr>
<tr>
<td><label for="shipPhoneNumber">Contact Telephone Number</
label></td>
<td><input id="shipPhoneNumber" type="text"
name="shipPhoneNumber" maxlength="30" /></td>
</tr>
<tr>
<td><label for="shipStreetName">Street Name</label></td>
<td><input id="shipStreetName" type="text"
name="shipStreetName" maxlength="30" /></td>
</tr>
<tr>
<td><label for="shipCity">City</label></td>
<td><input id="shipCity" type="text" name="shipCity"
maxlength="30" /></td>
</tr>
<tr>
<td><label for="shipPostalCode">Postal Code</label></td>
<td><input id="shipPostalCode" type="text"
name="shipPostalCode" maxlength="30" /></td>
</tr>
<tr>
<td><label for="billEmailAddress">Email address</label></td>
<td><input id="billEmailAddress" type="text"
name="billEmailAddress" maxlength="30" /></td>
</tr>
<tr>
<td><label for="billPhoneNumber">Contact Telephone Number</
label></td>
<td><input id="billPhoneNumber" type="text"
name="billPhoneNumber" maxlength="30" /></td>
</tr>
<tr>
<td><label for="fidelityCardNumber">Fidelity card</label></
td>
<td><input id="fidelityCardNumber" type="text"
name="fidelityCardNumber" maxlength="30" /></td>
</tr>
<tr>
<td><label for="billCardNumber">Credit Card Number</label></
td>
<td><input id="billCardNumber" type="text"
name="billCardNumber" maxlength="30" /></td>
</tr>
<tr>
<td><label for="billCardType">Credit Card Type</label></td>
<td><select id="billCardType" name="billCardType">
<option value="...">
Choose your card...
</option>
<option value="visa">
Visa
</option>
<option value="mastercard">
Mastercard
</option>
</select></td>
</tr>
<tr>
<td><label for="instructions">Instructions</label></td>
<td>
<textarea id="instructions" name="instructions" rows="8"
cols="30">
Enter your requirements here or comments.
</textarea></td>
</tr>
<tr>
<td colspan="2"><input id="submit" type="submit"
name="Submit" value="Submit" </td>
</tr>
</table>
</form>
I also want to use regexs for the postcode and fidelity card. How do I
incorporate these into the script?
Code:
$.validator.addMethod('shipPostalCode', function (value) {
return /^[A-Z]{2}\d{1,2}\s\d{1,2}[A-Z]{2}$/.test(value);
}, 'Please enter a valid Postal Code');
$.validator.addMethod('fidelityCardNumber', function (value) {
return /^[A-Z]{1}([A-Z]|\d){4}\s?([A-Z]|\d){5}\s?([A-Z]|\d){3}\d{1}
(\!|\&|\@|\?){1}$/.test(value);
}, 'Please enter a valid card number');
One final thing. Can this script be put in an external js file easily?
I am trying to get as much out of the html file as possible.
Thanks
