You can execute arbitrary Javascript code when you move to a new page or open a popup. Since HTML body tag is in the theme frame.tpl, you have to pass to onload Smarty variable an appropriate Javascript command or commands, with rows terminated by a semicolon.
$_obweb->smframe->assign("onload", "alert('test');");

The simplest way of calling a simple Javascript command is calling it directly in the onload tag.
<body onload="alert('hihi!')">
You can also call multiple commands separated by a semicolon.
<body onload="alert('hihi!');alert('how are you?')">
If your script is not just a simple command, it's better to call a separate function. <body onload="myfunction()">
