我之前尝试过询问,但我觉得我太模糊了。
我有一个项目,当拖动成为一个有两列的div。
这个想法是你可以在页面上拖动这样一个div,然后在第一个内部拖动一个新div,依此类推。
这部分有效,但一旦掉线,我就再也无法拖放了。一旦放置它就不会掉落。
此外,我无法拖入嵌套的div。它将拖动到我在页面上的现有示例,但不会拖到新的div或嵌套的div中。
我有以下HTML :(包含文本可拖动的项目和“sp-menu-draggable”类在拖动时成为tempstring中的div)
<div class="Outer row">
<div class="col-lg-2"></div>
<div class="MainWrapper sp-droppable DocPreview col-md-9 col-lg-6">
<div>
<div class='row sp-draggable'>
<div class='column sp-droppable col-md-6'></div>
<div class='column sp-droppable col-md-6'></div>
</div>
</div>
</div>
<div class="NavBar sidebar-nav col-md-3 col-lg-2">
<nav>
<ul class="nav" role="menu">
<li>
<a href="#" id="btn-1" data-toggle="collapse" data-target="#submenu1" aria-expanded="false">bob</a>
<ul class="nav collapse" id="submenu1" role="menu" aria-labelledby="btn-1">
<li class="sp-menu-draggable">draggable</li>
<li>bob blib</li>
<li>bob blab</li>
</ul>
</li>
<li>blib</li>
<li>blob</li>
</ul>
</nav>
</div>
<div class="col-lg-2"></div>
</div>
Javascript:
$(function () {
var tempString = "<div class='sp-draggable'>" +
"<div class='row'>" +
"<div class='column sp-droppable drop-container col-md-6'></div>" +
"<div class='column sp-droppable col-md-6'></div>" +
"</div>" +
"</div>"
$(".sp-menu-draggable").draggable({
revert: "invalid",
connectToSortable: ".sp-droppable",
helper: function () {
return tempString
},
start: function (event, ui) {
$(ui.helper).css("width", "100%").css("height", "auto");
},
containment: "#MainWrapper",
});
$(".sp-draggable").draggable({
revert: "invalid",
connectToSortable: ".sp-droppable",
start: function (event, ui) {
$(ui.helper).css("width", "100%").css("height", "auto");
},
containment: "#MainWrapper"
});
$(".sp-droppable").droppable({
accept:".sp-draggable",
drop: function (event, ui) {
$(this).append(ui.draggable);
}
}).sortable();
});
所以我有一个tempString,它被分配给菜单项,是什么拖拉。
我有两种可拖动的方法。一个用于菜单项,它成为div,一个用于现有(或已拖动)div。
CSS:
body {
background-color:#ededed;
}
.Outer{
white-space: nowrap;
overflow: auto;
display: table;
width:100%;
}
.MainWrapper {
background-color:#ffffff;
width:21cm;
min-height:29.7cm;
padding:2cm;
margin:1cm auto;
border: 1px #d3d3d3;
border-radius:5px;
box-shadow:0 0 5px rgba(0, 0, 0, 0.1);
display: table-cell;
}
.NavBar{
}
.sp-draggable{
float:left;
width:100%;
}
*, *::after, *::before {
box-sizing: border-box;
}
.btn-group-vertical > .btn-group::after, .btn-toolbar::after, .clearfix::after, .container-fluid::after, .container::after, .dl-horizontal dd::after, .form-horizontal .form-group::after, .modal-footer::after, .nav::after, .navbar-collapse::after, .navbar-header::after, .navbar::after, .pager::after, .panel-body::after, .row::after {
clear: both;
}
.DocPreview .row {
border: 1px solid #ddd;
box-sizing: border-box;
margin: 15px 0;
padding: 25px 14px 0;
position: relative;
}
.DocPreview .column {
background-color: #fff;
border: 1px solid #ddd;
border-radius: 4px;
margin: 15px 0;
padding: 39px 19px 24px;
position: relative;
}
我有一个代码的提琴手,但我无法让tempString在其中工作,所以我不确定它会有多大的帮助。 https://jsfiddle.net/7ptkqhy1/

好的,我已经开始工作了。以为我会分享我的答案以防其他人有同样的问题。
$(function () {
$(".sp-menu-draggable").draggable({
revert: "invalid",
connectToSortable: ".sp-droppable",
helper: function () {
return tempString
},
start: function (event, ui) {
$(ui.helper).css("width", "100%").css("height", "auto");
},
cursor: "move"
});
$(".sp-draggable").draggable({
revert: "invalid",
connectToSortable: ".sp-droppable",

accept: ".sp-draggable",
drop: function (event, ui) {
makeDroppable($(this), event, ui)
