  • 0

I am having a little bit trouble with the following. I have multiple form fields starting with “vendorName-” ending with a number. I would like to add a rule to the validate for these fields but I am not sure how to.

Here is what I have so far:

$().ready(function() { 

     $.validator.addMethod(
        "findRegex",
        function(value, element) {
            return /^.+::[1-9]\d{0,11}$/.test(value);
        },
        "Please check your input."
   );

    $('#myForm').validate({
            submitHandler: function(form){
                $("#formSub").html('<table style="font-size:11px; color:#333;"><tr><td><img border="0" src="images/ajax-loader.gif"/></td><td>Saving! Please wait...</td></table>');
                var options = { 
                    success: showResponse,
                    url:'save.cfm' 
                };
                $('#myForm').ajaxSubmit(options);
                return false;    
            }
    });

    showResponse = function(responseText, statusText) {
        $("#formSub").html(responseText);
    }


    $(":input[name^='vendorName-']").rules("add", { findRegex: true });  //    $('input[name^=vendorName]').

 });

    You can add the rules dynamically based on the selector, like this:

    $('#myForm').validate({
  submitHandler: function(form){ 
   ...
  }
});
$(":input[name^='vendorName-']").each(function() {
   $(this).rules("add", { findRegex: true });
});​

    You can give it a try here.

    It’s important that you call .rules() after .validate() so the validator itself it setup and ready. Also you have to use a .each() here, since .rules() only runs against the first element of the matched set.
