jQuery:完成拖动而不触发click事件

时间:2019-08-04 23:27:58

标签: javascript jquery draggable clickable

我正在尝试在以下页面中设置:

  1. 如果单击按钮,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”。

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)

这里要解决的主要问题是,将click上的常规#content事件与在拖动元素完成期间也会触发的其他“点击事件”区分开来。

您当前的代码中有一种可以用来实现所需行为的方法:

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:

$(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>

实际上,您所需的只是这些可读代码,

  • 为所有可拖动元素分配一个类.draggable
  • 将新类用作stack: '.draggable'
  • 将点击注册到您的'#container'而不是您的.trip元素上
  • 仅使用一个事件,"click"一个:
  • 隐藏所有.trip,但首先使用CSS .trip~.trip {display:none;}

jQuery( $ => {

  const $cont = $('#content');
  const $bttn = $('#button');
  const $trip = $('.trip');
  const tripL = $trip.length;
  let   i = 0;

  $('.draggable').draggable({stack:'div', containment:'body'});
  
  $bttn.on('click', function() {
    if (!$(this).hasClass('ui-draggable-dragging')) $cont.toggle();
  });

  $cont.on('click', function() {
    $trip.eq(++i % tripL).show().siblings($trip).hide();
  });

});
html, body { height:100%; margin:0;}

body {
  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;
}

.trip ~ .trip {display: none;}
<!-- PS: Add class="draggable" to draggable elements -->

<div id="button" class="draggable">Button</div>
<div id="content" class="draggable">
  <div class="trip" id="a">div 1</div>
  <div class="trip" id="b">div 2</div>
  <div class="trip" id="c">div 3</div>
</div>
