我在下面的代码使用脚本我正在制作可拖动和可放置的东西。目前我有两个可拖动内容的部分,两个地方可以删除,如果正确,那么系统将改变并说出正确的,我想知道是否有,我将能够只创建HTML divs和代码运行通过并将draggable与dropable相匹配。我的人有非技术性的backdround,有基本的HTML知识,所以你现在如何添加div并删除它们但他们能够处理脚本,我想知道,如果我的ID为1-10的可拖动的内容和相同的可丢弃的1-10所以id 1 draggable只能添加到id一个droppable。

您需要避免使用HTML id
并开始使用类。以下是使用working example:
您的HTML:
<div id="draggable_2" class="ui-widget-content draggable-item">
<p>draggable_2</p>
</div>
<div id="draggable" class="ui-widget-content draggable-item">
<p>draggable</p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable">
<p></p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable_2">
<p></p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable_3">
<p></p>
</div>
你的javascript:
$(function () {
$(".draggable-item").draggable();
$('.droppable-item').each(function (i, ele) {
// Gets the accepted from the HTML property "data-accept"
var accept = $(this).data('accept');
// This is just to show what the item accepts. you can remove it.
$(this).find('p').text('accepts: ' + accept);
// Init the jQuery UI droppable()
$(this).droppable({
accept: accept,
drop: function (event, ui) {
$(this)
.removeClass("ui-widget-header")
.addClass("ui-state-highlight")
.find("p")
.html("Dropped!");
},
out: function (event, ui) {
$(this).removeClass("ui-state-highlight").addClass("ui-widget-header")
.find("p")
.html("accept: " + accept);
}
});
});
});

如果我正确理解你的问题,你希望每个可拖动的只能放置它的droppable,而不是其他可放弃的div。
您已经通过在每个accept: "#draggable"
的代码中添加droppable
来实现这一目标。
你可以添加这个额外的代码行,这样如果你的draggable被丢弃到droppable以外的任何地方,它将返回到它的droppable。
$( "#draggable, #draggable2" ).draggable({ revert: "invalid" });
如果您向每个可拖动的html元素添加相同的类(如class=draggables
),则可以缩短此代码,然后您可以使用
$( ".draggables" ).draggable({ revert: "invalid" });
标记所有人。
