When I use code like this: $("#element") .on( 'click', function() { // do something } ) .on( 'touchstart', function(e) { e.preventDefault(); // do the same thing but on touch device like iPad f.e. // and more over PLEASE do not fire the click event also! } ); I am expecting that the click event is never never never fired (because of the hierarchy with which browser should work through the events

Is there a way to use event.preventDefault with focusOut? If not, why?

问题 I would like to prevent the default event from a focusOut (or blur ) event and keep the focus set to the specific input field. This is what I have already tried: using event.preventDefault() at the beginning and at the end of the function (for test purposes, not for style) return false; to prevent propagation setting the focus back to the element directly in the element (but I found that the focus still switches because the focus switch is executed after the .on() function executes. I know I

Correct way to set up a sequence of synchronous/asynchronous functions all of which can stop form submission and further processing?

由 巧了我就是萌 提交于 2019-12-25 08:58:14
问题 I need to call some functions in sequence on form submit button click - func1() -> func2() -> func3() ... -> func7() -> ... All these functions do some kind of validation/checking and if validation fails, display a confirmation dialog to the user. If the user confirms, the next function in queue is executed. Any of these functions could be doing some asynchronous task like sending Ajax request and depending on the result, showing the user some confirm dialog. Details I have asynchronous

问题 Simplified HTML: <ul> <li class="no-link"><a>Should not be clickable</a> <ul> <li><a>Should be clickable</a></li> <li><a>Should be clickable</a></li> </ul> </li> </ul> Javascript: jQuery(document).ready(function( $ ) { $('a').parent().click(function(e) { if($(this).hasClass('no-link')){ e.preventDefault(); } }); }) Works fine on the link that should not be clickable, but also affects the two descendant a tags. Why? I thought parent() only traversed up a single step in the DOM. I'm adding the
