forms

问题 Say, I have a form with a text input and a submit button. If there are no buttons in the form, just submit event triggers, but if there is at least one button with no type attribute or with type="submit" , it clicks it too. Now, when I enter something in the input and then press Enter, I see that both button click and form submit events are triggered. Example: <form> <input type="text" /> <button onclick="alert('submitted');">Submit</button> </form> I suppose the form clicks the button

问题 I've searched high and low for the answer to this but can't find it anywhere. I have a form which has the HTML 'required' attributes and it does a fine job of highlighting the fields that need to filled in before submission...or would do, but the system which my form is bolted onto (of which I have no control over) submits the form anyway after a few seconds. It relies on Javascript for it's submission. Therefore I'd like to write a Javascript script to check all fields for a required

问题 When a user clicks, for example, "Take a Picture" how can we prepopulate the create.html.erb form with attributes specifically set for that featured challenge, like do for 12 days and do on Tue, Thu ? I am using the reform gem. #challenges_controller def new @challenge = Challenge.new respond_modal_with @challenge, location: root_path end #challenges/new.html.erb <%= simple_form_for(@challenge, html: { data: { modal: true } }) do |f| %> <%= f.text_field :action, placeholder: 'Enter a Custom

问题 So I have a web app that i'm working on with a form that requires all of the fields to be populated before submitting. If you try to submit the app without a field being populated, it loads the page again with the errors. Once you fill all the fields in and click submit, it does a redirect to the same page and shows a message which is generated from flashdata. See simplified example below. Welcome controller: function show_view() { $this->load->view('form'); } function process_form() { //

问题 I'm starting a new ASP.NET MVC 3 project and am going to implement some screens that are read only by default but allow the user to edit information by clicking on an Edit button. I want these screens to be AJAXed. I have previously used the jQuery Form Plugin to implement similar screens on an ASP.NET MVC 2 project. I've just discovered the existence of Ajax.BeginForm() and was wondering whether I should use that since it is built in, instead of using the jQuery Form Plugin. I've done a
