c# - 函数

Question

我想在 HidenField 中存储 TextBox 值，我在按钮单击功能上调用 javascript 函数正在调用获取消息 嗨，但是...... HTML textBox 也是，但在这两种情况下都发生相同的情况......实际上在 Ajax Tab Container 中使用的 HTML 代码可能是这个问题...... 如何解决此类问题

function f11() {
    alert("Hi")
    alert("hi..." + document.getElementById("txthtmltextbox").value)
    document.getElementById("txtuncheaderHF").value = document.getElementById("txthtmltextbox").value;
    document.getElementById("txtrootFolderHF").value = document.getElementById("txthtmltextboxroot").value
}

这是我的 HTML 代码

<asp:Panel ID="pnlhfconfig" runat="server" Height="100%" Width="100%">
    <table bordercolor="gainsboro" bgcolor="white" style="border-bottom-width: 1px; border-bottom-style: solid;

希望您了解 JQuery 并使用 JQuery，您将轻松获得面板的内部控制。因为当您的页面在浏览器上呈现时。 Html 代码与 .NET(ASPX 页面)有所不同。

您将使用以下语句获取/设置面板内部控件值。

$("#<%=pnlhfconfig.ClientID %> input[id='<%= txtuncheaderHF.ClientID %>']").val($("#<%=pnlhfconfig.ClientID %> input[id='<%= txthtmltextbox.ClientID %>']").val());
