我正在尝试设置以下页面:
- 如果您单击按钮,则可以看到DIV。
- 如果您单击DIV,则可以看到下一个Div。
- 如果您移动按钮,则没有»单击«(所需的行为(
我遇到的问题是,如果您移动DIV,则下一个DIV出现 - 这不是我想要的。拖动事件结束后不应显示"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?:)
(一个可能的问题也是纯JavaScript与jQuery混合(
谢谢
在这里要解决的主要问题是区分#content
上的常规click
事件与其他"单击类似事件",这些事件在拖动的元素完成期间也会触发。
您当前的代码有一种方法,您可以将其目的用于所需的行为:
if (! $(this).hasClass('ui-draggable-dragging')) {
/* This was a "regular click event"
}
因此,在代码的情况下,您可以按以下方式进行修改:
$(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,您需要的只是可读的代码,
- 将类
.draggable
分配给所有可拖动元素 - 将新类用作
stack: '.draggable'
- 注册单击您的
'#container'
,而不是您的.trip
元素 - 仅使用一个事件,即
"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>
