我正在尝试为RadioButtonList的每个ListItem的任何 <input>、<td> 或 <label> 元素添加一些onmouseover和onmouseout属性。我该怎么做呢？这是我尝试过的。这不起作用...

ASPX 文件...

<asp:RadioButtonList ID="RadioButtonListPaymentFrequency"
    runat="server"
    RepeatDirection="Vertical"
    RepeatLayout="Table"
    RepeatColumns="1" />

VB代码背后...

将 ListItemOneTimeOnly 调暗为新的 ListItem("One-Time Only", "1")
ListItemOneTimeOnly.Attributes.Add("onmouseover", "ddrivetip('示例：一次性支付 300 美元的总金额意味着 1 次支付 300 美元。')")
ListItemOneTimeOnly.Attributes.Add("onmouseout", "hideddrivetip()")
RadioButtonListPaymentFrequency.Items.Add(ListItemOneTimeOnly)

将 ListItemMonthly 调暗为新 ListItem("Monthly", "12")
ListItemMonthly.Attributes.Add("onmouseover", "ddrivetip('示例：每月支付 300 美元的总金额意味着 12 次支付 25 美元。')")
ListItemMonthly.Attributes.Add("onmouseout", "hideddrivetip()")
RadioButtonListPaymentFrequency.Items.Add(ListItemMonthly)

将 ListItemQuarterly 调暗为新 ListItem("Quarterly", "4")
ListItemQuarterly.Attributes.Add("onmouseover", "ddrivetip('示例：每季度支付 300 美元的总金额意味着 4 次支付 75 美元。')")
ListItemQuarterly.Attributes.Add("onmouseout", "hideddrivetip()")
RadioButtonListPaymentFrequency.Items.Add(ListItemQuarterly)

Dim ListItemSemiannually As New ListItem("Semiannually", "2")
ListItemSemiannually.Attributes.Add("onmouseover", "ddrivetip('示例：每月支付 300 美元的总金额意味着 2 次支付 150 美元。')")
ListItemSemiannually.Attributes.Add("onmouseout", "hideddrivetip()")
RadioButtonListPaymentFrequency.Items.Add(ListItemSemiannually)

生成的 HTML...

<table id="RadioButtonListPaymentFrequency" border="0">
    <tbody>
        <tr>
            <td>
                <input id="RadioButtonListPaymentFrequency_0" name="RadioButtonListPaymentFrequency" value="1" type="radio">
                <label for="RadioButtonListPaymentFrequency_0">One-Time Only</label>
            </td>
        </tr>
        <tr>
            <td>
                <input id="RadioButtonListPaymentFrequency_1" name="RadioButtonListPaymentFrequency" value="12" type="radio">
                <label for="RadioButtonListPaymentFrequency_1">Monthly</label>
            </td>
        </tr>
        <tr>
            <td>
                <input id="RadioButtonListPaymentFrequency_2" name="RadioButtonListPaymentFrequency" value="4" type="radio">
                <label for="RadioButtonListPaymentFrequency_2">Quarterly</label>
            </td>
        </tr>
        <tr>
            <td>
                <input id="RadioButtonListPaymentFrequency_3" name="RadioButtonListPaymentFrequency" value="2" type="radio">
                <label for="RadioButtonListPaymentFrequency_3">Semiannually</label>
            </td>
        </tr>
    </tbody>
</table>

你没有。除非您使用解决方法或子类RadioButtonList。我个人只是使​​用JQuery来附加事件处理程序。
