我正在使用具有双面多个选择框的表单页面。框1将从服务器加载所有可用日期。双击或选择并单击＆gt;时，框1选项将移至框2.框2选项将突出显示并选中。
在保存期间，我在其中一个javascript代码中添加了no.selected = true来选择框2中的所有选项并保存。
但是当我在编辑模式下进入页面时，我遇到了一些问题：
1.当页面加载时，所有选定的选项将被加载并在框2中突出显示。我必须通过再次在选项标签中添加selected ='selected'来预先选择它们。这将使他们保持选中状态，这样当我点击更新时，我将设法获取他们的值并根据更新记录。
2.但是，当我从框2中将单个选项转移回框1时，在框1和框2中选择并突出显示所有内容，是否有办法不在框中选择内容？
3.我不介意方框2始终保持选中状态，但是有没有CSS或隐藏所选高光的东西？
4.在保存和更新期间，我需要服务器管理以从box2中的选项标签请求值。我所做的是请求长字符串中的所有值，然后将其拆分并保存。如果未选择选项，则无法获取值。再次，如何在从Box 1移动到Box 2时让选项保持选中状态？
5.双击一次，它将在方框1中选择全部？请参阅
Double click highlight Box1 issue.
6.向后移动或向后移动它会再次在框1中以深灰色突出显示？请参阅Transfer back highlight Box 1 issue
对所有的大师们，请帮帮我，非常感谢你。

答案 0 :(得分：0)
基本上我弄错了。我应该删除javascript代码中的所有no.selected = true并添加以下Jquery
$(document).ready(function () {
$('#btnUp').click(function () {
$('#ToLB').each(function () {
$('#ToLB option').attr("selected", "selected");
});
});
});
$(document).ready(function () {
$('#btnSave').click(function () {
$('#ToLB').each(function () {
$('#ToLB option').attr("selected", "selected");
});
});
});
基本上，当单击btnSave或btnUpdate时，Jquery将选择所有选项。
因此，服务器将设法获取选项标签的值。
