我正在尝试建立一个像这样工作的系统:您可以在列表的 5 个元素之间进行选择,并将其拖放到特殊位置。一旦您放下它,就会出现一个弹出窗口,询问您要更改该元素的内容。然后修改后的元素就会出现在特殊的地方。
它只能工作一次,但如果您想添加另一个元素,这个新元素会删除旧元素以取代它的位置。
每次有东西被丢弃时,我都会尝试添加一个类,这样就不会删除任何内容(这样你就会有名为 drop1、drop2、drop3 等的类),但不知何故,它似乎没有改变任何东西,我不明白为什么。
无论如何,这是代码:
$(function() {
$('#allFacets').sortable({
connectWith: 'ul',
delay: 150,
helper: "clone",
placeholder: 'placeholder',
start: function(e, ui) {
ui.item.show(); // force jquery ui to display the original
}
});
$('#userFacets').sortable({
connectWith: 'ul',
delay: 150,
helper: "clone",
placeholder: 'placeholder',
receive: function(e, ui) {
ui.item.clone().appendTo(this); // append a copy
$("#userFacets.userFacets.ui-sortable").each(function(i){
$(this).addClass("received"+ (i+1));
});
var step = prompt("Choose a name");
$(this).html(step);
ui.sender.sortable("cancel"); // return the original
}
}).on("dblclick", "li", function() {
$(this).remove();
});
});
.facet-container {
width: 330px;
}
.right {
float: right;
}
.left {
float: left;
}
p {
clear: both;
padding-top: 1em;
}
.facet-list {
list-style-type: none;
margin: 0;
padding: 0;
margin-right: 10px;
background: #eee;
padding: 5px;
