我正在使用jQuery UI制作一些图钉,可以将其拖放到地图上。
每个图钉都需要与其他图钉保持一定的净空空间(不能放置在任何其他图钉的30像素之内),在拖动过程中,该图腾周围带有黑色光晕。目前,可以将图钉拖动到彼此上方并放置在彼此之上,而我希望将图钉拖动以围绕已放置的任何图钉进行操作,例如:
是否有足够简单/轻巧的方法来做到这一点?预先感谢!
$(document).ready(function() {
$(".pin").draggable({
grid: [ 5, 5 ],
start: function(e, ui) {
$(this).addClass('placed');
$('.placed').css('box-shadow' , '0 0 0 15px rgba(0, 0, 0, 0.3), 0 7px 10px 0 rgba(0, 0, 0, 0.7)');
},
stop: function(e, ui) {
$('.pin').css('box-shadow' , '0 0 0 0 rgba(0, 0, 0, 0), 0 3px 8px 0 rgba(0, 0, 0, 0.3)');

我可以使用上面使用JQuery UI Draggable Collision
的彼得牧师的建议链接来工作jsfiddle.net/RichardGouw/h14jcqvx/28/
我对活动销周围有光环的想法略有改变,但碰撞效果仍然相同
HTML
<script src="http://code.jquery.com/jquery-1.7.2.js"></script>
<script src="http://code.jquery.com/ui/1.8.18/jquery-ui.js"></script>
<!-- Include links to UI Draggable Collision files -->
<div class="pin"></div>
<div class="pin"></div>
<div class="pin"></div>
<div class="pin"></div>
CSS
.pin {
width: 20px;
height: 20px;
background-color: #65C02F;
margin: 7px;
border-radius: 20px;
-moz-border-radius: 20px;
-webkit-border-radius: 20px;
box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
-moz-box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
-webkit-box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
transition: box-shadow 0.2s;
}
.pin.placed.boundary {
box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
-moz-box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
-webkit-box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
}
jQuery
// make pins draggable (using jQuery UI)
$(".pin").draggable({
// apply collision effect (using UI Draggable Collision)
obstacle: ".placed",
preventCollision: true,
// optional, snap to pixel grid (using jQuery UI)
grid: [5,5],
// animate on start of drag (using jQuery UI)
start: function(e, ui) {
$(this).removeClass('placed'),
$('.placed').addClass('boundary');
},
// animate on end of drag (using jQuery UI)
stop: function(e, ui) {
$(this).addClass('placed'),
$('.placed').removeClass('boundary');
}
});
