熟悉javascript的帮忙看看下面代码，应该是javascript代码，找了javascript手册没看到有代码里的location.reload.
jsreload之类的属性。熟悉javascript的帮忙看看加个注释，谢谢了。


<?php
function jsReload( $window = "window" )
{
echo '
<script> '. $window .'.location.reload(); </script>';
}

function jsTWinReload()
{
jsReload( "top" );
}

function jsTWinReset( $form_name )
{
echo '
<script> top.document.'. $form_name .'.reset();</script>';
}

function jsTWinAlert( $msg = "管理" )
{
echo '
<script> top.alert("'. $msg .'"); </script>';
}

function jsSelfClose()
{
echo '
<script> window.close(); </script>';
}

function jsGo2Url ( $url , $window="window" )
{
echo '
<script> '. $window .'.location.href="'. $url .'"; </script>';
}

function jsTWin2Url( $url )
{
jsGo2Url( $url , "top" );
}

function jsTWinBack()
{
echo '
<script> top.history.go(-1); </script>';
}
?>
