在将它们移动到目标之前，如何清除.draggable元素的子项上的样式？ [英] How can I clear the styles on a .draggable element's children, before moving them to the target?

问题描述

我有一个div，我使用优秀的fcbkcomplete jquery插件对list-items进行一些操作。然而，当我用可拖动和可排序的页面插入它时，我意识到当我移动它时，额外的装饰会被冻结。至少可以说，这使最终结果感觉不完整。我知道我可以在拖动之前拦截mousedown事件，但我不知道要修改哪些元素以保持样式简单。

I have a div in which I do some manipulation of list-items using the excellent fcbkcomplete jquery plugin. However, when i plug this in with my draggable and sortable page, I realized that the extra decorations are frozen when I move it over. This makes the end result feel unpolished, to say the least. I know I can intercept the mousedown event before the drag, but I don't know what elements to modify to keep the style simple.

这是fcbkcomplete 的演示，它类似于facebook的消息撰写功能。在我的jsfiddle中，一旦我准备将div拖到下面的可排序列表中，我想要所有花哨的装饰（关闭图像，分离成蓝色框，开始输入...工具提示，以及最后的空文本框到被一个简单的字符串替换，这样当我点击h1标题时，我仍然可以检索这些值。有人知道怎么做吗？

Here is a demo of fcbkcomplete, it resembles facebook's message compose feature. In my jsfiddle, once I am ready to drag the div to the sortable list below, I want all the fancy decoration (close image, separation into blue boxes, the "Start to type..." tooltip, and the final empty textbox to be replaced by a simple string, such that when I click on the h1 header, I still can retrieve the values. Does anyone know how to do this?

                            $("#draggable").draggable({
                            connectToSortable: "#sortable",
                            helper: "clone",
                            revert: "invalid",
                            distance: 20
                        });

                        $('#draggable').each(function () {
                            $(this).mousedown(function () {

                                // Need to clear styles here
                                //$(this).parent().children('.maininput').hide('blind', 500);
                            });
                        });

推荐答案

提出类似的问题，答案也解决了这个问题。不得不使用自定义助手而不是克隆，但一切都很好。至于droppable，

Asked a similar question, and the answer solves this problem as well. Had to use the custom helper instead of clone, but everything worked out fine. As for the droppable,

                $("#container").droppable({
                accept: '.product',
                drop: function (event, ui) {
                    var x = ui.helper.clone();
                    x.removeClass().attr('style', '');
                    x.addClass("ui-state-default");
                    x.appendTo('#container');
                    ui.helper.remove();
                }
            });

问题是，我没有使用过！

the problem is, I wasn't using one!
