validation

问题 Trying to create validation for an input field, which will put a message alongside the input field. As you can see, the user cannot enter anything below 500 or anything above 800 <input type="text" name="amount" id="amount" maxlength="6" autocomplete="off"/> <span class="paymentalert"></span> Please excuse my javascript as I'm still learning. $(function(){ var min = 500.00; var max = 800.00; if ("#amount" < 500.00){ return ("Your payment must be between £500 and £800"); else if ("#amount" >

问题 I'm working on a form that is supposed to validate the input in several textboxes when the user clicks the "submit" button. If any of the required boxes are left blank or have an incorrect type of input or format, the border of those textboxes is supposed to turn red and return to the normal color when the requirements are met. For example, a phone number is either supposed to be 7 or 10 digits long, if the user enters a six digit number like (123456), the border around this field should turn

问题 I am working on a basic blog application with Codeigniter 3.1.8 and Bootstrap 4 . The posts, of course, have main images. There is a default image if no image is uploaded by the user but, if an image is uploaded, there are only 3 types allowed : jpg, jpeg and png. Wanting to warn the user in case she/he tries to upload other file formats, I did this in the Posts controller: // Upload image $config['upload_path'] = './assets/img/posts'; $config['allowed_types'] = 'jpg|jpeg|png'; $config['max

问题 Using Thymeleaf + Spring and form validation, I want to display errors that are related to a field next to this field. <input type="text" th:field="*{companyName}" class="form-control" placeholder="Code client" th:errorClass="'error'"/> If the field has an error, the class "error" is applied indeed. But is there an easy way to display also the validation error of the field? 回答1: Use this code to display error: <p class="alert alert-danger" th:if="${#fields.hasErrors('companyName')}" th:errors

问题 i am not very advanced user of Django. I have seen many different methods online, but they all are for modified models or too complicated for me to understand.
