The rules function tries to obtain the parent form of the element. The dynamically created input element should be added to the DOM (inside the form) before calling rules() function.rules() is called when the user presses the ‘add’ link to create duplicate rows. In the example, the validate() function is called in the initialization stage. Calling validate() initializes the validation setup for the form. The validate() function should already be called before calling rules() function.See the demo A Few Things to Note While Adding Validations Dynamically: and the rules() function adds new validation rules to the element. The ‘.itmqty’ selector selects the text element. To add validation rules to dynamically generated elements, use the rules() function on the element. It is quite easy to add validations to dynamically generated elements in run time. You can use the validation plugin with complex dynamic forms as well. See the demo Validations for Dynamically Generated Elements When there is a validation error in the group element the error message is placed neatly next to the group. The tooltip is attached to the container. So in this example, a container div is placed. We need to position the error message just outside the group’s boundary. There is one special handling needed for group type elements like radio group or checkbox group. $(tipelement).tooltipster( 'content', errtxt) $(tipelement).data( 'last_error',errtxt) Last_error = $(tipelement).data( 'last_error') (This solution is adapted from this stackoverflow answer by sparky )ĮrrorPlacement : function(error, element) We set the trigger to custom and set auto hide false. Fortunately, the tooltipster plugin has options to override the default behavior. It opens when the user moves the mouse over an element and hides when the mouse is moved away. Tooltips, by default has a certain behavior. See the demo In the first part of the code, we attach the tooltip to the form elements. In the following example, we use the Tooltipster plugin to display the error message. You can customize the way the errors are displayed in the jQuery Validation Plugin. Tooltips have the advantage that it floats on top of the element and grabs the user’s attention. We don’t have to validate if this element is optional and empty. To avoid this, we first do an optional() check. However, our regular expression check will fail and it will still throw the error. The field could be optional and the user might have skipped the input. There is one thing that can happen when you check the input value against a regular expression. See the demo time we defined the function along with the addMethod (rather than defining the function and then calling addMethod(), like in the previous example). In simple form, the format is like this: $('#formid').validate( (where form is like this: ) the validate() function takes the rules, messages and other options for the validation.
