问题 I am using Struts 2 <s:checkbox /> in my form processing, along with AngularJS and jQuery. Before submitting, I need validation and until now we do this in the project: When we press Submit button, this function is called: $scope.processForm('myForm', '<s:url value="/form/validate.action" />', '<s:url value="/form/save.action" />'); , where processForm(formId, validateUrl, submitUrl) is a function defined by us: $scope.processForm = function(form, validateUrl, submitUrl) { window.scroll(0,0);

问题 I'm currently styling form elements with a custom CSS class to style text inputs differently, as in: $submit = new Zend_Form_Element_Submit('login'); $submit->setLabel('Log in') ->setAttrib('class', 'submit'); And $username = new Zend_Form_Element_Text('username'); $username->setLabel('Username') ->setAttrib('class', 'textinput'); But let's say I have multiple forms, and want to style all text elements with textinput and all submit elements with submit by default. Is there anyway to do this

问题 I'm trying to figure out how to use jQuery in my Rails 4 app. I have a boolean attribute in my table. I ask a question to get a true or false answer using radio buttons in the form. If the answer is true, my objective is to ask follow up questions which are hidden until true is selected in the form. I have this form question: <%= f.input :ethics_relevance, as: :radio_buttons, :label => 'Is an ethics review relevant?' %> </div> <div id="project_ethics_relevance_content" class="content hidden">

问题 My form is working fine with the validations being done by PHP. I have three fields: Name, EMail and Message. Form and PHP code is within the same pgae, same page is called for validations when user submits the form. When a user submits the form, same page is called and it checks whether the form is submitted or not. If the form is submitted it then does the validations for blank entries and throws error message below the fields to inform user that field is left blank. It also shows error

问题 I have a HTML form that contains text fields, checkboxes, radiobuttons and a submit button. I'd like that submit button is enabled only if contents of fields are modified. Now here is the catch: if the user modifies field contents back to original values, the form button should be disabled again. Original field value "foo" => submit button is disabled User changes field value to "bar" => submit button becomes enabled User changes field value back to "foo" => submit button becomes disabled
