Solution 1

Question not written properly, but looks like you want to find the control in focus at a given time.

You can try either of these:
1. Use document.activeElement property in JS to know the currently focused element. Use it accordingly.
2. Use jQuery selector :focus, example:

JavaScript

var element = document.querySelector(":focus");

function abc()
{
if (document.getElementById('TextBox1').focus())
{
// write in textbox1
}
else
{
// write in text box2
}
}
++++++++++++++++++++++++++++++++++

1> i have a keyboard in javascript for login window.
2> i have two text boxes (a) login_name (b)Password
whenever i try to write with keyboard on page ....... it writes only in login_name text box

my else part is not working ..
+++++++++++++++++++++++++++++++++++
i am calling function abc() on every button of keyboard on page.

I guess, document.getElementById('TextBox1').focus() will not work as TextBox is a server control and you cannot access it directly using it's normal ID.

Try:
<%=TextBox1.ClientID %>

Do a View Source of your page, find the textbox ID you want to focus and use that ID here.
