preventdefault

问题 I have a few products in a mySQL database whose links are being retrieved in my script with $producturl. These url's actually add the product to the cart (http://www.example.com/cart/?add-to-cart=1127). I am trying to create a script that will allow the user to add products to the cart but NOT redirect them, just execute the link so the user stays on the same page. I am using preventDefault and stopPropgation but it is not working. The alert shows up but the link itself is not executing when

问题 This question already has answers here : Selecting multiple from an html select element without using ctrl key (7 answers) Closed 3 years ago . Every time I add an event listner that somehow does a preventDefault on a change to the select-box, it scrolls to the top. For a minimal example, see below: document.getElementById('foo').onmousedown = function(e) { e.target.parentElement.focus(); e.target.selected = !e.target.selected; e.preventDefault(); return false; } <select multiple size="5" id=

问题 I have a video player on my website and want to change the default seek time when a user clicks left or right arrows to 10 seconds (like netflix or youtube). Using a combination of preventDefault() and stopImmediatePropagation() I've managed to achieve desired effect however when a user goes fullscreen, default events are still passed through (along with my code). document.onkeydown = function(event) { switch (event.keyCode) { case 37: event.preventDefault(); event.stopImmediatePropagation();

问题 I am trying to bind the 'CTRL+N' key combination, like this: var ctrlPressed = false; var nCode = 78; var ctrlCode = 224; var cmdCode = 17; document.addEventListener ("keydown", function(e){ if( e.keyCode == ctrlCode || e.keyCode == cmdCode){ ctrlPressed = true; }else{ ctrlPressed = false; } console.log(e.keyCode); }); document.addEventListener ("keyup", function(e){ if(ctrlPressed && e.keyCode == nCode){ e.preventDefault(); nou_element(parent); return; } }); Please note: jQuery isn't

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 So I have a link in my application like this: <a href="/threads/my-first-thread/" @click="openThread">My first thread</a> At the moment, when I click the link, the browsers follows the href link and also executes the "openThread" method. I want to keep the link in there so that it shows the user where a click is going to bring him to, but I don't want the browser to actually follow the link (I open a lightbox instead and change the url with pushState). I want it to only execute the given
