Question

我的.ascx页面中有一个 cblSchedule 复选框列表，允许选择每日/每周：

<div class="form-group" id="schedule">
    <label class="control-label col-md-2" id="lblSchedule">Schedule</label>
    <div class="col-md-3">
        <div class="input-group">
            <asp:CheckboxList ID="cblSchedule" ClientIDMode="Static" CssClass="chkLabel" runat="server" AutoPostBack="false" CellPadding="5" CellSpacing="5" RepeatDirection="Horizontal" RepeatLayout="Table" onchange="ToggleSchedule(this)" >
                <asp:ListItem Text="Daily" Value="Daily"></asp:ListItem>
                <asp:ListItem Text="Weekly" Value="Weekly"></asp:ListItem>
            </asp:CheckboxList>
        </div>
    </div>
</div>

选中每周时，会显示 chkSelectDay 复选框列表：

<div class="form-group" id="divSelectDay" >
    <label class="control-label col-md-2" id="lblSelectDay">Select Day of Week</label>
    <div class="col-md-3">
        <div class="input-group">
            <asp:CheckBoxList ID="chkSelectDay" CssClass="chkLabel" ClientIDMode="Static" runat="server" AutoPostBack="false" CellPadding="5" CellSpacing="5" RepeatDirection="Horizontal" RepeatLayout="Table"> 
                <asp:ListItem Value="Monday">Mon</asp:ListItem>
                <asp:ListItem Value="Tuesday">Tue</asp:ListItem>
                <asp:ListItem Value="Wednesday">Wed</asp:ListItem>
                <asp:ListItem Value="Thursday">Thu</asp:ListItem>
                <asp:ListItem Value="Friday">Fri</asp:ListItem>
                <asp:ListItem Value="Saturday">Sat</asp:ListItem>
                <asp:ListItem Value="Sunday">Sun</asp:ListItem>
            </asp:CheckBoxList>
        </div>
    </div>
</div>

我有一个切换功能，当在 cblSchedule 中选中/取消选中每周时，会显示/隐藏 chkSelectDay ：

function ToggleSchedule(controlId) {
    var frmControl = document.getElementById(controlId.id);
    var divDay = document.getElementById("divSelectDay");

    var checkbox = frmControl.getElementsByTagName("input");
    var counter = 0;
    for (var i = 0; i < checkbox.length; i++) {
        if (checkbox[i].checked)
        {
            if (checkbox[i].value == "Weekly")
                divDay.style.display = 'block';
        }
        else
        {
            if (checkbox[i].value == "Weekly") {
                divDay.style.display = 'none';

            //UNCHECK ALL chkSelectDay checkboxes <--

            }
        }
    }
}

我想添加在 cblSchedule 中未选中每周时取消选中 chkSelectDay 中所有复选框的功能。

我试图通过$('#chkSelectDay')来检索复选框计数。

但是我无法使用.Count或.Length，所以无法使用for-loop来设置.Checked = false。

谢谢

您应该知道的第一件事是，默认情况下，census=pd.Series([2000,4432,5435,43252,63463,423432,3525,54353,6363]) census.index=['AL','AL','AL','AL','AK','AK','AK','AK','AK']将其值存储在for (int maxNames = 0; maxNames < names.Length; maxNames++) { // Also, move your input WITHIN the loop userInput = Console.ReadLine(); // store the name in userInput if (userInput == "") // if the entry is null, stop taking names. { Console.WriteLine("You entered {0}", names); Console.ReadKey(); break; } else if (userInput == "QUIT") // if the entry is QUIT, stop taking names. { Console.WriteLine("You entered {0}", names); Console.ReadKey(); break; } else // if it isn't null or QUIT, continue populating the array until we hit the max. { // since maxNames is now properly starting at 0, // you don't need your other name counter variable. // just use maxNames. The loop process will increase it next cycle through names[maxNames] = userInput; } }中，而不在客户端显示它。您需要在CheckBoxList内添加ViewState属性，以使复选框列表值可在客户端使用：

ClientValue

然后，处理ListItem事件以确保传递了<asp:CheckboxList ID="cblSchedule" ClientIDMode="Static" CssClass="chkLabel" runat="server" AutoPostBack="false" CellPadding="5" CellSpacing="5" RepeatDirection="Horizontal" RepeatLayout="Table" onchange="ToggleSchedule(this)" > <asp:ListItem Text="Daily" Value="Daily" ClientValue="Daily"></asp:ListItem> <asp:ListItem Text="Weekly" Value="Weekly" ClientValue="Weekly"></asp:ListItem> </asp:CheckboxList>值，否则请取消选中所有change复选框：

Weekly
