forms

问题 I am using template driven forms for adding the task, and there are 2 input fields of type number for estimated mins to complete task, one field is for estimated number of hrs and another is for estimated minutes to complete the task since the task estimate can be done either in hours like 1hrs , or in hours and minutes like 1Hrs 30Mins , so i want to set attribute required to inputs conditionally. So one of the 2 inputs must be set or form validation error will occur if both inputs are empty

问题 Right now even if input fields are empty , if submit button is pressed it shows alert"message": and then redirects to window.location="URL" What I m looking for is it only shows done alert and redirects if input fields are filled <form> <input type="text" placeholder="enter name here"> <input type="number" placeholder="enter number here"> <input type="submit" id="submitbutton" value="submit"> </form> </center> </body> <script type="text/javascript"> const submitit = document.getElementById(

问题 Here is what I am doing : I have a form set component that fetch data through ajax to populate the form set. The user may modify those datas from the form and submit. Problem : This work well. However, I noticed that if i navigate to another page and then hit the browser "go back one page" button, the form is there (the DOM in the template) but empty. There is no data bound in v-model input fields anymore... Most posts about this behavior are connected to vue-router, that I do not use. I

问题 I want to drag a PictureBox, and I have managed to do so. But my application doesn't do it as smoothly as Windows photo viewer. I mean the difference isn't huge or anything, but it's noticeable. Is there something I could do to make it a little less choppy? This is my simple code: int MOUSE_X = 0; int MOUSE_Y = 0; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { picBox.Image = Image.FromFile(@"D:\test_big.png"); picBox.Width = 3300; picBox.Height

问题 I'm trying to make a bot that can fill a form with random values from the login form in the Bidoo site. I am able to send keys with .SendKeys("keys") but I'm not able to send them randomly. I've already made a working random string generator but I'm not able to use it with the auto form filler (the "Bot" that I'm trying to make). I've tried using IWebDriver and IWebElement but when I start the "Bot" it says that it can't find the XPath (if I try to use the CSS selector or the ID or the Class

问题 I'm using Formik for validation in a React app. Validation is working correctly, but my onChange handler does not fire: <Field type="text" name="name" placeholder="First Name" component={Input} onChange={() => console.log("gfdg")} /> Link to Sandbox Why is this? 回答1: Inside Input , the way you have ordered the props passed to your input element means your onChange is being overwritten by Formik's onChange . When you create a Field with a custom component (i.e. Input in your case), Formik
