【问题描述】:
我在 jQuery 上使用可选择的多选存在问题。
我确实对正在发生的事情有所了解。
当拼接项目时,他们得到新的索引。这就是我认为的问题所在。但我似乎找不到解决方案。
非常感谢您的帮助!
我创建了这个JSFiddle
这里和 JSFiddle 一样。但这下面不起作用。我不明白为什么。我必须粘贴下面的代码才能发布。
JSFiddle 可以工作。所以检查一下。
var arrSelectedItems = [];
var arrItems = [];
$("#showItems").click(function() {
arrItems.push([1, "Mr", "John", "Andersson"]);
arrItems.push([2, "Mrs", "Anna", "Svensson"]);
arrItems.push([3, "Mr", "Klas", "Olsson"]);
arrItems.push([4, "Mrs", "Lovisa", "Henriksson"]);
arrItems.push([5, "Mr", "Anders", "Annikadotter"]);
arrItems.push([6, "Mrs", "Klara", "Annasson"]);
showItems();
});
function showItems() {
$('#selectable').empty();
$(arrItems).each(function(i) {
var stringItems = arrItems[i].toString().split(",");
$('#selectable').append("<li class=\"ui-widget-content\" value='" + i + "'>" + stringItems[1] + " " + stringItems[2] + " " + stringItems[3] + "</li>").attr("class", "ui-widget-content");
});
}
function showSelectedItems() {
$('#selected').empty();
$(arrSelectedItems).each(function(i) {
var stringItem = arrSelectedItems[i].toString().split(",");
$('#selected').append("<li class=\"ui-widget-content\" value='" + i + "'>" + stringItem[2] + " " + stringItem[3] + " " + stringItem[1] + "</li>");
});
}
$(function() {
$("#selectable").selectable({
stop: function() {
$(".ui-selected", this).each(function() {
var $this = $(this);
var index = $this.attr("value");
var pushString = arrItems[index];
arrSelectedItems.push(pushString);
arrSelectedItems.sort();
arrItems.splice(index, 1);
arrItems.sort();
showItems();
showSelectedItems();
});
}
});
});
$(function() {
$("#selected").selectable({
stop: function() {
$(".ui-selected", this).each(function() {
var $this = $(this);
var index = $this.attr("value");
var pushString = arrSelectedItems[index];
arrItems.push(pushString);
arrItems.sort();
arrSelectedItems.splice(index, 1);
arrSelectedItems.sort();
showItems();
showSelectedItems();
});
}
});
});
