问题 I am trying to get the text value from a dropdown select using [useState} in React Hooks. I just get the value (number) rather than the text. Ive copied the bits of code below which control the select dropdown. What am i missing here? Thanks. const [addrtype, setAddrType] = useState('Home') function handleAddrTypeChange(e) { setAddrType(e.target.value); console.log(addrtype) } <select defaultValue={addrtype} onChange={handleAddrTypeChange} className="browser-default custom-select"> <option

问题 I have searched many other threads about this and I can't see what I am doing wrong, I am trying to send form values to a php file to send as an email, however the pages always refreshes. I have tried using event.preventDefault and return false both before and after my ajax call but none seem to work. What am I missing here here is my code. HTML <form method="post" name="registerForm" class="form"> <label for="fullName" class="form__fullname form__label">Full Name</label> <input type="text"

问题 I am currently using Visual Studio, and I don't know if this is a glitch or not, but when I go into the form properties, and show the events, there are two events called KeyDown and KeyUp . Now when I do the same for a PictureBox , it has way less events and no KeyDown and KeyUp events. Does the PictureBox support less events then other things? Is this a glitch? Screenshot of Form1 properties: Screenshot of PictureBox1 properties: 回答1: Its not a glitch. Its the way it is. You don't type in
