Double quotes cannot include double quotes,not only in javascript,any other language is the same.

<body onload="document.getElementById('search').focus()">

Solution 2

I'f you're using jquery:

$(function() {
  $("#search").focus();
});

or prototype:

Event.observe(window, 'load', function() {
  $("search").focus();
});

or plain javascript:

window.onload = function() {
  document.getElementById("search").focus();
};

It's "Better" for readability than an inline event...

No matter what I do, this page doesn't work at all. I want it to focus on the input box on load.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Home Screen</title>
<style type="text/css">
input {border:0px;}
input:focus {outline:none;}
</style>
</head>
<body onload="document.getElementById("search").focus()">
<input id="search" />
</body>
</html>

I know I'm breaking a bunch of rules with this code, so you don't need to say anything about that.

EDIT:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Home Screen</title>
<style type="text/css">
input {border:0px;}
input:focus {outline:none;}
</style>
</head>
<body onload="document.getElementById('search').focus()">
<input id="search" onblur="setTimeout(document.getElementById('search').focus(),10)" />
</body>
</html>

EDIT 2:

<script type="text/javascript">
function refocus()
{
setTimeout(document.getElementById("search").focus(),10);
}
</script>

<input id="search" onblur="refocus()" />
