Try this, using Jquery

$("[id$='txtName']").val();
$("[id$='txtAddress']").val();

Use data keys inside your text boxes.

      --Start UserControl UserDetails--
     <asp:TextBox runat="server" id="txtName" data-key="name"></asp:TextBox>
     <asp:TextBox runat="server" id="txtAddress" data-key="address"></asp:TextBox>
    --End UserControl UserDetails-

<uc1:UserDetails runat="server" ID="UserDetails1" data-usercontrol = "UserDetails1" />

in jquery,

$("[data-usercontrol='UserDetails1']").find("[data-key='name']").val();
$("[data-usercontrol='UserDetails1']").find("[data-key='address']").val();

You can use id selector. But since you have used asp.net, it might be rendered with different id in HTML.

Hope this helps!

Copy the id of particular textbox from Developer Tools and then just use that id like below

var textLength = $("#ContentBody_ucMFA1_txtACode").val().length;
