Really Easy Field Validation with JQuery

Again JQuery has improved and simplified from the process outlined earlier in this blog

for form validation just add jquery.validate plugin and then in the code add:-

$("#commentForm").validate();

or more likely you’ll have a more complex form so you’ll need to specify a few attributes

var validator = $("#health").validate({
			rules: {
				radiofield: "required",
				textfield: "required",
				email: {required: true,email: true},
				name: "required"
  			},
			messages: {
				email: {
					required: "Please enter a valid email address",
					minlength: "Please enter a valid email address",
				},
				radiofield: "Please Select The number of items to Check"
			},
			// the errorPlacement has to take the table layout into account
			errorPlacement: function(error, element) {
				if ( element.is(":radio") )
					error.appendTo( element.parent() );
				else if ( element.is(":checkbox") )
					error.appendTo ( element.next() );
				else
					error.appendTo( element.parent() );
			},
 
		})

And don’t forget to handle the form with javascript disabled!
