如何从购物车中删除该项目?
当然,您希望能够将项目拖放回来。
$(function() {
$( "#catalog" ).accordion();
$( "#catalog li" ).draggable({
appendTo: "body",
helper: "clone"
});
$( "#cart ol" ).droppable({
activeClass: "ui-state-default",
hoverClass: "ui-state-hover",
accept: ":not(.ui-sortable-helper)",
drop: function( event, ui ) {
$( this ).find( ".placeholder" ).remove();
$( "" ).text( ui.draggable.text() ).appendTo( this );
}
}).sortable({
items: "li:not(.placeholder)",
sort: function() {
// gets added unintentionally by droppable interacting with sortable
// using connectWithSortable fixes this, but doesn't allow you to customize active/hoverClass options
$( this ).removeClass( "ui-state-default" );
}
});
});
答案 0 :(得分:16)
这应该有效:
$(function() {
$("#catalog").accordion();
$("#catalog li").draggable({
appendTo: "body",
helper: "clone"
});
$("#cart ol").droppable({
activeClass: "ui-state-default",
hoverClass: "ui-state-hover",
accept: ":not(.ui-sortable-helper)",
drop: function(event, ui) {
$(this).find(".placeholder").remove();
$("<li></li>").text(ui.draggable.text())
.addClass("cart-item")
.appendTo(this);
}
}).sortable({
items: "li:not(.placeholder)",
sort: function() {
$(this).removeClass("ui-state-default");
}
});
$("#catalog ul").droppable({
drop: function(event, ui) {
$(ui.draggable).remove();
},
hoverClass: "ui-state-hover",
accept: '.cart-item'
});
});
备注强>:
cart-item
类。ul
删除了;此区域仅接受cart-item
s。发生丢弃后,它会调用remove()

您可以将商品从购物车拖回目录中的任何类别,但我认为制作只能拖动到原始类别的商品非常容易。
