问题 Once I\'ve fired an evt.preventDefault() , how can I resume default actions again? 回答1: As per commented by @Prescott, the opposite of: evt.preventDefault(); Could be: Essentially equating to 'do default' , since we're no longer preventing it. Otherwise I'm inclined to point you to the answers provided by another comments and answers: How to unbind a listener that is calling event.preventDefault() (using jQuery)? How to reenable event.preventDefault? Note that the second one has been accepted

问题 This question already has answers here : What's the difference between event.stopPropagation and event.preventDefault? (7 answers) Closed 4 years ago . Firstly, in JavaScript\'s event model, you will come across a concept called as event bubbling (which makes an event to propagate from child element to a parent element). In order to avoid such kind of bubbling effect, many developers use an event method called stopPropagation( ) . Alternatively, developers have started to use return false

问题 jquery toggle calls preventDefault() by default, so the defaults don\'t work. you can\'t click a checkbox, you cant click a link etc etc is it possible to restore the default handler? 回答1: In my case: $('#some_link').click(function(event){ event.preventDefault(); }); $('#some_link').unbind('click'); worked as the only method to restore the default action. As seen over here: https://stackoverflow.com/a/1673570/211514 回答2: Its fairly simple Lets suppose you do something like document

How to preventDefault on anchor tags?

问题 Let\'s say I have an anchor tag such as <a href=\"#\" ng-click=\"do()\">Click</a> How can I prevent the browser from navigating to # in AngularJS ? 回答1: UPDATE : I've since changed my mind on this solution. After more development and time spent working on this, I believe a better solution to this problem is to do the following: <a ng-click="myFunction()">Click Here</a> And then update your css to have an extra rule: a[ng-click]{ cursor: pointer; } Its much more simple and provides the exact

event.preventDefault() vs. return false (no jQuery)

由 Deadly 提交于 2019-11-26 02:33:52
问题 I wondered if event.preventDefault() and return false were the same. I have done some tests, and it seems that If the event handler is added using old model, for example elem.onclick = function(){ return false; }; Then, return false prevents default action, like event.preventDefault() . If the event handler is added using addEventListener , for example elem.addEventListener( \'click\', function(e){ return false; }, false ); Then, return false doesn\'t prevent the default action. Do all

What&#39;s the difference between event.stopPropagation and event.preventDefault?

由 孤者浪人 提交于 2019-11-25 22:28:25
问题 They seem to be doing the same thing... Is one modern and one old? Or are they supported by different browsers? When I handle events myself (without framework) I just always check for both and execute both if present. (I also return false , but I have the feeling that doesn\'t work with events attached with node.addEventListener ). So why both? Should I keep checking for both? Or is there actually a difference? (I know, a lot of questions, but they\'re all sort of the same =)) 回答1:
