完成拖动而不触发click事件

完成拖动而不触发click事件

问题描述

我正在尝试在以下页面中设置

I am trying to set up the following page where:

  1. 如果单击该按钮,则可以看到一个div.
  2. 如果单击div,则可以看到下一个div.
  3. 如果您移动按钮,则不会出现»click«(期望的行为)

我遇到的问题是,如果您移动div,则会出现下一个div-这不是我想要的.在其上发生拖动事件后,不应显示下一个div".

The problem I am having is that if you move the div, the next div appears - this is not what I want. The "next div" should not be displayed after a drag event finishes on it.

这是我的代码:

$(function() {
  $("#button").draggable({
    stack: 'div',
    containment: "body"
  });
});

$('#button').on('mouseup', function() {
  if (!$(this).hasClass('ui-draggable-dragging')) {
    // click function
    $("#content").toggle();
  }
});

$(function() {
  $("#content").draggable({
    stack: 'div',
    containment: "body"
  });
});

let containers = $('.trip').hide();
let firstContainer = containers.first().show();

containers.on('click', function() {
  //Get current element and next sibling
  let elem = $(this);
  let next = elem.next('.trip');

  //Does sibling exist?
  if (next.length) {
    next.show();
  } else {
    firstContainer.show();
  }
  elem.hide();
});
body {
  width: 100vw;
  height: 100vh;
  padding: 0;
  margin: 0;
  left: 0;
  top: 0;
  background-color: grey;
}

#button {
  width: 100px;
  height: 100px;
  background-color: cyan;
}

#content {
  display: none;
  cursor: all-scroll;
  top: 10%;
  left: 10%;
  position: absolute;
}

.trip {
  width: 200px;
  height: 200px;
  background-color: blue;
  color: white;
}
<div id="button">Button</div>

<div id="content">
  <div class="trip">div 1</div>
  <div class="trip">div 2</div>
  <div class="trip">div 3</div>
</div>

有没有办法解决这个问题? :)
(一个可能的问题是,纯JavaScript与jQuery混合使用了)
谢谢

Is there a way to solve this? :)
(a possible problem is also that pure JavaScript is mixed with jQuery)
Thanks

推荐答案

此处要解决的主要问题是,将#content上的常规click事件与在完成过程中也触发的其他点击类似事件"区分开来的元素.

The main problem to solve here is in distinguishing a regular click event on #content, from other "click like events" that are also triggered during completion of the element being dragged.

您当前的代码中有一种可以用来实现所需行为的方法:

You're code currently has a method of doing that which you could re purpose for the desired behaviour:

if (! $(this).hasClass('ui-draggable-dragging')) {
   /* This was a "regular click event"
}

因此,对于您的代码,您可以对其进行如下修改:

So in the case of your code, you could revise it as follows:

$(function() {

  /* Combine on ready logic into one place */

  $("#button").draggable({
    stack: 'div',
    containment: "body"
  });

  $("#content").draggable({
    stack: 'div',
    containment: "body"
  });

  /* Hide all trip elements except for first */
  $('.trip', '#content').not(':first').hide();
});

$('#button').on('mouseup', function() {
  if (!$(this).hasClass('ui-draggable-dragging')) {
    $("#content").toggle();
  }
});

$('#content').on('mouseup', function() {

  /* Reuse same logic in #button mouseup handler */
  if (!$(this).hasClass('ui-draggable-dragging')) {

      /*
      If content element if not dragging, treat mouse up as conclusion
      of click event and rotate visibility of trip elements like this
      */
      let trip = $('.trip:visible', '#content');
      let next = trip.next().length === 0 ?
          $('.trip:first', '#content') : trip.next();

      trip.hide();
      next.show();
  }
});
body {
  width: 100vw;
  height: 100vh;
  padding: 0;
  margin: 0;
  left: 0;
  top: 0;
  background-color: grey;
}

#button {
  width: 100px;
  height: 100px;
  background-color: cyan;
}

#content {
  display: none;
  cursor: all-scroll;
  top: 10%;
  left: 10%;
  position: absolute;
}

.trip {
  width: 200px;
  height: 200px;
  background-color: blue;
  color: white;
}
<div id="button">Button</div>

<div id="content">
  <div class="trip">div 1</div>
  <div class="trip">div 2</div>
  <div class="trip">div 3</div>
</div>
