Question

所有

点击一个复选框后，我有以下代码更新我的aspx页面中隐藏字段的文本：

BiopsyDone：

< asp:CheckBox ID ="cbLiverBiopsy" runat="server" Checked="false" OnCheckedChanged="BiopsyResults_SelectedIndexChanged"/> <br/>
    < asp:HiddenField ID="hide" runat="server" Value=" " /> 

 < script>

        $(document).ready(function () {
            $("#cbLiverBiopsy").change(function () {
                $("#hide").val("The liver biopsy results were ");
            });
        });

    </script>

程序运行后，单击复选框后隐藏字段不会更新。有什么建议吗？

谢谢，艾伦

Answer 1

使用ClientID进行此操作的方法

$('#<%= hide.ClientID %>').val("The liver biopsy results were ");

然后它不需要是静态的

Answer 2

为隐藏输入设置clientidmode="static" ..

< asp:HiddenField ID="hide" runat="server" Value=" " clientidmode="static"/>

将其作为..

访问

document.getelementid('hide').value="The liver biopsy results were";

或

$('#<%= hide.ClientID %>').val("The liver biopsy results were ");

Answer 3

按ID获取

<强> HTML：

 < asp:HiddenField ID="hide" runat="server" Value=" " />

<强> jQuery的：

$('#<%= hide.ClientID %>').val("The liver biopsy results were ");

按类别获取

<强> HTML：

 < asp:HiddenField ID="hide" class="hideClass" runat="server" Value=" " />

<强> jQuery的：

$('.hideClass').val("The liver biopsy results were ");

使用JQuery更新隐藏字段
