focus on textbox when panel is visible

Mar 14, 2017 06:45 AM|scala_1988|LINK

I've two asp panels. One panel panel_srch_passenger is visible on page load and another panel panel_post_passCode is only visible after the button is pressed. Initially on page load txtPassengerId is set visible which is inside panel_srch_passenger. But after the button pressed I need to focus on different text box which is inside the panel_post_passCode.

How can I do this using javascript? My code is not working. Please help me.

<script type="text/javascript">        
        $(function () {
            document.getElementById('<%=txtPassengerId.ClientID%>').focus();
            if (document.getElementById("panel_post_passCode").style.visibility = "visible")
            {
                alert("test");
                document.getElementById('<%=txtpassCode.ClientID%>').focus();
            }
            
        });
		
<asp:Panel ID="panel_srch_passenger" runat="server" DefaultButton="btn_search">
        <fieldset>
            <legend>Search</legend>
            <div class="div_labels">
                <b>Patient Id :</b>
                <asp:TextBox ID="txtPassengerId" runat="server" />
                <asp:Button ID="btn_search" runat="server" Text="Search" OnClick="btn_search_Click" />
            </div>
        </fieldset>
    </asp:Panel>
	
<asp:Panel ID="panel_post_passCode" runat="server" Visible="false">
         <div class="give_labels">
                <b>Passenger Code :</b>
                <asp:TextBox ID="txtpassCode" runat="server" />
            </div>
    </asp:Panel>

Hi,

scala_1988
But after the button pressed I need to focus on different text box which is inside the panel_post_passCode.

You don't need JS, you can set focus using asp.net (serverside) code

Call the txtpassCode.Focus() method in button click event handler

or check this site: http://stackoverflow.com/questions/1533871/how-to-use-setfocus-on-text-box-control

try updating code like this:

if ($("[id*='panel_post_passCode']").is(":visible"))
            {
                alert("test");
                document.getElementById('<%=txtpassCode.ClientID%>').focus();
            }

Happy Coding ! Mark as Answer if it helps.

You code seems correct to me, try using Document.Ready event:

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="../Scripts/jquery-1.12.4.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            document.getElementById('<%=txtPassengerId.ClientID%>').focus();
            if (document.getElementById("panel_post_passCode").style.visibility = "visible")
                document.getElementById('<%=txtpassCode.ClientID%>').focus();
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <asp:Panel ID="panel_srch_passenger" runat="server" DefaultButton="btn_search">
            <fieldset>
                <legend>Search</legend>
                <div class="div_labels">
                    <b>Patient Id :</b>
                    <asp:TextBox ID="txtPassengerId" runat="server" />
                    <asp:Button ID="btn_search" runat="server" Text="Search" OnClick="btn_search_Click" />
                </div>
            </fieldset>
        </asp:Panel>

        <asp:Panel ID="panel_post_passCode" runat="server" Visible="false">
            <div class="give_labels">
                <b>Passenger Code :</b>
                <asp:TextBox ID="txtpassCode" runat="server" />
            </div>
        </asp:Panel>
    </form>
</body>
</html>

        protected void btn_search_Click(object sender, EventArgs e)
        {
            panel_post_passCode.Visible = true;
        }

Output:

In only jQuery, script code will be:

    <script type="text/javascript">
        $(document).ready(function () {
            $("#txtPassengerId").focus();
            if ($("#panel_post_passCode").is(":visible"))
                $("#txtpassCode").focus();
        });
    </script>

Hi,

Try this clientside script using pure JS, it will work irrespective of panel visible or not.

<script>
window.onload=function(){
	var ele = document.getElementById('<%=txtPassengerId.ClientID%>');
	if(ele) ele.focus();
	ele = document.getElementById('<%=txtpassCode.ClientID%>');
	if(ele) ele.focus();
};
</script>

Did you try client side script that I posted earlier? I saw it as working on my side. You may post if you see further issue or still not working.

Hi scala_1988,

Base on your description. I make an working example.

  <script type="text/javascript">
  window.onload=function(){
	var ele = document.getElementById('<%=txtPassengerId.ClientID%>');
          ele.focus();
	
};
        function SomeMethod() {     
           var ele = document.getElementById("panel_post_passCode");
           ele.style.display = "block";
           if (document.getElementById("panel_post_passCode").style.display == "block") {
                document.getElementById('<%=txtpassCode.ClientID%>').focus();               
            }
            return false;
        }
    </script>

<asp:Panel ID="panel_srch_passenger" runat="server">
        <fieldset>
            <legend>Search</legend>
            <div class="div_labels">
                <b>Patient Id :</b>
                <asp:TextBox ID="txtPassengerId" runat="server" />
                <asp:Button ID="btn_search" runat="server" Text="Search" OnClientClick="return SomeMethod();" />
            </div>
        </fieldset>
    </asp:Panel>
	
<asp:Panel ID="panel_post_passCode" runat="server"  style="display:none;">
         <div class="give_labels">
                <b>Passenger Code :</b>
                <asp:TextBox ID="txtpassCode" runat="server" />
            </div>
    </asp:Panel>
