我有一个Angular-Kendo treeview
和剑道grid
一起。当我drag
一个treeivew项目时,我正在Kendo网格上创建一个drag hint
。
这是我的插件:http://plnkr.co/edit/55MdA3NajWtNYUIYNXGr?p=preview
我在网格上有一个隐藏的叠加div
,我需要时会visible
。例如,$('.section-top-right .drop-zone').css('visibility', 'visible');
例如:
drag: function (e) {
// DROP ZONE DIV
$('.section-top-right .drop-zone').css('visibility', 'visible');
if ($.contains($('#dropAreaDimen')[0], e.dropTarget)) { //make sure mouse is hovering the grid
e.setStatusClass("k-add");
}
else {
e.setStatusClass('k-denied');
}
}
<style scoped>
.drop-zone {
color:crimson;
visibility: hidden;
border: 2px dashed;
background-color: seashell;
height: 200px;
width: 720px;
top: 400px;
position: absolute;
opacity: .5;
z-index:10;
}
.drop-text {
font-size: 16px;
font-weight:bold;
color: crimson;
text-align:center;
}
</style>
**两个主要问题:
1)在drag
事件中,我在打开k-add
Kendo鼠标提示时遇到问题。仅"+"
图标仅会打开一秒钟,但会再次关闭。
我正在使用$.contains
来确保用户将鼠标悬停在#dropAreadimen
上:
if ($.contains($('#dropAreaDimen')[0], e.dropTarget)) {
e.setStatusClass("k-add");
}
else {
e.setStatusClass('k-denied');
}
2)如何动态地使height
的{{1}}始终符合网格的高度。
我的插件在这里:plunk。注意:请展开上面的树视图,然后拖动任何叶子项目以查看当前拖动提示。
******更新*********
drop-zone
答案 0 :(得分:0)
我能够通过以下方式解决我的问题:
drop-zone
类装饰的隐藏div。drag
事件中,我使用jQuery显示drop-zone
div并调整高度和宽度。drop
事件中,我只创建了div hidden
。drag
事件中,我还使用e.dropTarget.className
检查鼠标悬停的位置(允许我打开k-add
拖动提示。
