c# - ASP 自定义日历控件在回发时消失

Question

我创建了一个自定义日历控件，它在大多数情况下都运行良好。我的问题是，无论何时发布，控件都会消失，即使用户仍在悬停也是如此。我希望他们能够更改月份、日期等等，而 divCalendarDropDown 不会消失。有什么建议吗？

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DateTimePickerObject.ascx.cs" Inherits="DateTimePicker.DateTimePickerObject" %>

<script type="text/javascript">
    var canHover = true;

    var calendarControl = $(".calendarControl"), flip = $(".divCalendarDropDown"),
    state = $.cookie("ToggleStatus");

    function setCalendarVisibility(className) {
        if (canHover) {
            var dropDown = document.getElementById("divCalendarDropDown");
            dropDown.className = className;
        }
    };
    function OnClick_Calendar() {
        var dropDown = document.getElementById("divCalendarDropDown");
        if (dropDown.style.height >= 1) {
            canHover = true;
            dropDown.className = 'divHidden';
        }
        else {
            canHover = false;
            dropDown.className = 'divNormal';
        };
    };
</script>
<style type="text/css">
    .textboxCalendar {
        position: relative;
        display: block;
        width: 215px;

我会把它放在评论中，但我现在还不能； )

我认为您不能使用 asp:Calendar 控件禁用回发到服务器，因此请尝试向您的 DIV“divCalendarDropDown”添加一个默认类 - 例如

<div id="divCalendarDropDown" class="divNormal" onMouseOver="setCalendarVisibility('divNormal');" onMouseOut="setCalendarVisibility('divHidden');">

如果这不起作用，我会尝试向该 DIV 添加另一个操作，例如 onload 上的 onblur - 例如

<div id="divCalendarDropDown" onload="setCalendarVisibility('divNormal');" onMouseOver="setCalendarVisibility('divNormal');" onMouseOut="setCalendarVisibility('divHidden');">

希望对您有所帮助! JM
