event-bubbling

问题 I have a text input inside a div. Clicking on the input should set it to focus and stop the bubbling of the div click event. I've tried the stopPropagation and preventDefault on the text input event but to no avail. The console logs shows that the div click still executes regardless. How to stop the div click event from executing? // html <div (click)="divClick()" > <mat-card mat-ripple> <mat-card-header> <mat-card-title> <div style="width: 100px"> <input #inputBox matInput (mousedown)=

问题 I'm tryin' to make the article's link clickable on the whole article space. First, I did the hover thing, changing color on mouseover and so on... then on click it should trigger the link, but this gives a "too much recursion". I think it's a event bubbling problem. I tried to work with event.cancelBubble = true; or stopPropagation() with no luck. Worse luck! anyone? $("div.boxContent").each(function() { if ($(this).find(".btn").length) { var $fade = $(this).find("div.btn a > span.hover");

问题 I have form that calls the function GenerateWords when it is submitted and returns false. <form id="3Form" onsubmit="GenerateWords(this); return false;"> This is causing problems with Google Tag Manager implementation as it does not bubble up to the form submit listener. I understand event.preventDefault(); needs to be used and return false removed but don't know how to implement this. The current javascript I have is: function GenerateWords(F) { var strWords = F.words.value; if ... condition

问题 I am having trouble with firing up same event on all DIVs which have class "card" as shown in below screenshot: <div class="row"> <div class="col-md-1"> <div class="margin"></div> <div class="card"> <div class="front">CardClick</div> <div class="back">1</div> </div> </div> <div class="col-md-1"> <div class="margin"></div> <div class="card"> <div class="front">CardClick</div> <div class="back">2</div> </div> </div> <div class="col-md-1"> <div class="margin"></div> <div class="card"> <div class

问题 I have three objects ObjectA has an ObjectB, ObjectB has an ObjectC. When ObjectC fires an event I need ObjectA to know about it, so this is what I've done... public delegate void EventFiredEventHandler(); public class ObjectA { ObjectB objB; public ObjectA() { objB = new ObjectB(); objB.EventFired += new EventFiredEventHandler(objB_EventFired); } private void objB_EventFired() { //Handle the event. } } public class ObjectB { ObjectC objC; public ObjectB() { objC = new ObjectC(); objC

问题 This question already has answers here : Why the onclick element will trigger twice for label element (5 answers) Closed 3 years ago . I have an click event on window . There is also a checkbox and a label for the checkbox. When you click on the label, the window's click event gets called twice, once for the checkbox, and once for the label. I tried adding e.stopPropagation(); to the events listener, but it didn't help. Why is the event getting called twice, and what can I do to fix it?

问题 If I'm not returning false from an event callback, or using e.stopPropagation feature of jQuery, the event bubbles up the DOM. In most scenarios I don't care if the event bubbles or not. Like with this DOM structure example: ​<div id="theDiv"> <form id="theForm" > <input type="submit" value="submit"/> </form> </div>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ Normally, I don't have multiple nested submit callback like this: $('#theDiv').submit
