【问题描述】:
我无法让我的按钮在回发后执行点击。我正在验证网页上模态窗口中的一些文本框,这些文本框仅在单击按钮后出现。目前回发后网页重新打开,模式窗口关闭,需要打开。我的代码中没有处理程序,单击按钮并运行 html 代码以调出模态窗口。一旦我发回消息,我需要这个按钮来执行点击,以便启动验证。我曾尝试使用 btnSickness.Click() 但它似乎不喜欢这样,而且似乎在任何地方都找不到任何东西!代码:
public partial class _Default : System.Web.UI.Page
{
int i = 0;
protected void Page_Load(object sender, EventArgs e)
{
if (i > 0)
{
}
}
protected void chkDoctor_SelectedIndexChanged(object sender, EventArgs e)
{
if (drpDoctor.SelectedValue == "Yes")
{
txtIfNoWhy.ReadOnly = true;
txtIfNoWhy.BackColor = Color.LightGray;
i++;
}
else if (drpDoctor.SelectedValue == "No")
{
txtDocName.ReadOnly = true;
txtHouseName.ReadOnly = true;
txtStreet.ReadOnly = true;
txtTownCity.ReadOnly = true;
txtCounty.ReadOnly = true;
txtPostalcode.ReadOnly = true;
txtInitialDate.ReadOnly = true;
txtTreatmentRecieved.ReadOnly = true;
txtCurrentTreatment.ReadOnly = true;
txtDocName.BackColor = Color.LightGray;
txtHouseName.BackColor = Color.LightGray;
txtStreet.BackColor = Color.LightGray;
txtTownCity.BackColor = Color.LightGray;
txtCounty.BackColor = Color.LightGray;
txtPostalcode.BackColor = Color.LightGray;
txtInitialDate.BackColor = Color.LightGray;
txtTreatmentRecieved.BackColor = Color.LightGray;
txtCurrentTreatment.BackColor = Color.LightGray;
i++;
}
}
}
模态窗口代码:
<div class"modal" id="myModal"></div>
<div class="row-fluid">
<div class="span2">
<asp:Button runat="server" class="btn" data-toggle="modal" href="#Div1" ID="btnSickness" Text="Submit a Sickness Form" />
<div class="modal hide" id="Div1">
<div class="modal-header">
<button class="close" data-dismiss="modal">×</button>
<h3>Sickness Form</h3>
</div>
<div class="modal-body">
<p>Please fill in the following information regarding your sickness</p>
<br />
<p>Sickness Date From:</p>
<asp:TextBox runat="server" ID="txtSicknessFrom"></asp:TextBox>
<br />
<p>Sickness Date To:</p>
<asp:TextBox runat="server" ID="txtSicknessTo"></asp:TextBox>
<br />
<p>Absence Date To:</p>
<asp:TextBox runat="server" ID="txtAbsenceFrom"></asp:TextBox>
【问题讨论】:
-
if (i > 0)=>i永远不会 != 0 由于 http 的无状态。除此之外,我不明白这个问题。 “以便启动验证” 什么验证?如果您需要在服务器端调用Page.Validate()触发验证。 -
验证文本框只读。但要做到这一点,需要回发
-
SelectedIndexChanged事件是服务器端事件。它永远不会在没有回发的情况下被调用,i是一个在页面呈现后立即被释放的变量,它不会在回发中存活,并且总是以 0 初始化。 -
好的,我只需要在回发后执行点击的帮助。
-
这个模态是通过javascript显示的吗?
