Focus the first input on load only if no input is focused

I'm trying to set a default focus for all the pages of my site but without changing the focus on page reload.

I mean:

My current code is as follows:

$(document).ready(function() {

    if($(':focus').length === 0) {
        $(':input:not([type="hidden"]):first').focus();
    }

});

The condition is true every time!

$(document).ready({

window.onload=function(){
if(session.Storage.getItem("text3")){//if key= text3 is set,then change the focus to 3rd text box.
$('#your3rdTextID').focus();
}


$('#your3rdTextID').focus(function(){
    session.Storaage.setItem("text3","selected")//here you set the key as text3 and value as selected for later use.
});


});

You can provide with your own custom conditions.This is just a small example.Hope it helped you.Good luck with your project.

This will work (tested in latest Chrome, IE7 and IE10). Sets a cookie on focus remembering the last focused element, if not, it defaults to the first. It relies on jquery.cookie.js (usage explained in this SO answer). Here is the full HTML+JS source of a minimal working example. Consider changing the cookie name and the input selector (currently 'input'):

<!doctype html>
<html>
<head>
    <title>focus test</title>
    <meta charset="utf-8" />
    <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
    <script type="text/javascript" src="jquery.cookie.js"></script>
    <script type="text/javascript">
        $(document).ready(function(){
            var $input = $('input'), // get all the inputs
                cookieName = 'lastInputFocusIndex', // for consistency
                lastIndex = $.cookie(cookieName) || 0; // get the last known index, otherwise default to zero
            $input.on('focus',function(){ // when any of the selected inputs are focused
                if ( $(this).attr('type') !== 'submit' ) {
                    $.cookie(cookieName,$input.index(this)); // get their index in the $input list and store it
                }
            });
            $input.eq(lastIndex).focus(); // when the page loads, auto focus on the last known index (or the default of 0)
        });
    </script>
</head>
<body>

<form method="get" action="">
    <p><input type="text" name="first" /></p>
    <p><input type="text" name="second" /></p>
    <p><input type="text" name="third" /></p>
    <p><input type="submit" value="Go" /></p>
</form>

</body>
</html>

Alternatively, you could write your own raw cookies instead of using the cookie helper jQuery plugin; I used it to simplify things.
