【问题描述】：
我在我的项目中使用 jQuery UI，尤其是 selectables 和 dialogs。当我有一个选定的 HTML 项目并打开一个对话框时，选定的项目会被取消（取消）选择。我搜索了为什么它取消（取消）选择它但没有结果。有人知道如何预防吗？

【问题描述】：
查看您的代码后，我发现了一些不足，主要与带有我昵称 okai 的注释的行有关，因此请在里面查找此字符串。
因为我不懂你的语言，很抱歉，我用英文更改了标签 move 并在上下文菜单中测试了 move 功能，现在它可以工作了。 我首先在您的菜单中移动了移动功能，因此您可以直接在“sn-p 运行”中看到，而无需以完全模式打开它。
如果您需要在点击表格外部时添加取消选择表格行的功能，您可以执行以下操作：
$('html').click(function(e){
....
if ($(e.target).is('html')) {
ins.element.find('.ui-selected').removeClass('ui-selected');
}
告诉我。
$(function () {
$("table tbody.toBeSelected").selectable({
stop: function() {
$(".ui-selected", this)
.each(function() {
var index = $("table tbody").index(this);
});
}
});
$('html').click(function(e){
var ins = $( "table tbody.toBeSelected" ).selectable( "instance" );
// clear the selected list
ins.selectees = [];
// remove the selected class
/*****

* okai: The following line is your problem: comment it!

*/
//ins.element.find('.ui-selected').removeClass('ui-selected');

是的，这可能会解决我的问题。实际上，当我选择一个项目然后从上下文菜单中打开一个对话框窗口时，所选项目将变为未选中状态。在 ui-jquery 中删除了包含
.removeClass("ui-selected")但没有结果的每一行 -
不幸的是，有些东西删除了
ui-selected类。没用 -
看下面我的回答
