我是javascript + jquery的新手,我正在使用一个调度工具来迭代课程数据,将当前房间写入表格,并根据单元格创建和定位课程表#39; s id。所有这些都很好,但我在使用jquery-ui扩展拖放功能时遇到了麻烦。
基本上,每个课程都有自己唯一的课程,分配给该课程中的所有跨度(组###),每个范围都有自己唯一的ID([abc ...] ###)。如果我抓住任何跨度,我希望能够将所述跨度及其兄弟在.group ###中放到新的计划位置,(或者可能移动一个跨度,从旧位置删除其兄弟,并重新创建它们在相关的位置)但我不知道如何去做。我的真实代码将有超过7周的课程,但为了清晰起见,小提琴仅包括2个。
下面是拖放jquery(带有一些注释的想法)。
$(document).ready(function(){
$("span").on("dragstart", function (event) {
//var x = $(this).attr('class');
//var z = $(this).attr('id');
var dt = event.originalEvent.dataTransfer;
dt.setData('Text', $(this).attr('id'))
});
$('table td').on("dragenter dragover drop", function (event) {
event.preventDefault();
if (event.type === 'drop') {
var data = event.originalEvent.dataTransfer.getData('Text',$(this).attr('id'));
de=$('#'+data).detach();
de.appendTo($(this));
//var x = $(de).attr('class').split(' ')[1];
//var b = $("." + x +":not(:has(" + de +"))");
//console.log(b);
};
});
});

由此,我们可以做一个基本的工作示例:
$(function() {
$(".crse").draggable({
opacity: 0.35,
revert: "invalid",
containment: $("#scOut tbody"),
helper: "clone",
cursor: "move",
start: function(e, ui) {
$(this).parent().toggleClass("filled slot");
}
});
$("td[id^='Room']").droppable({
accept: ".crse",
drop: function(e, ui) {
addCourse(ui.draggable, $(this));
}
});
function addCourse($item, $target) {
$item.fadeOut(function() {
$item
.appendTo($target)
.fadeIn();
});
}
});

如果你想基于选择器移动一个组,你可以这样做,但它更复杂。我们可以将组数据添加到start
中的帮助程序,然后将该组附加到drop
中。或者,您只需使用拖动的项目并在drop
中创建该组,然后附加该组。
<强>更新强>
正如我所提到的,移动多个项目可能会更复杂。
考虑一下:https://jsfiddle.net/Twisty/rgw049r6/6/
我们必须检测更改的内容并定位其他项目。
