UC知道PHP判断表单为空的函数，为什么不管用？

function post()
{
if(document.form('searname').value=='')
{
alert("Please enter the keywords!");
document.form('searname').focus();
return false;
}
}
echo '<form method="post" action="search_admin_database.php" onsubmit="return post()">' . "\n\n";
{
if(document.form('searname').value=='')
{
alert("Please enter the keywords!");
document.form('searname').focus();
return false;
}
}
echo '<form method="post" action="search_admin_database.php" onsubmit="return post()">' . "\n\n";
晕，function post是PHP函数还是JS函数，这是从哪里学来的呢？
function post()
{
if(document.f1.searname.value=='')
{
alert("Please enter the keywords!");
document.form('searname').focus();
return false;
}
}
<form name="f1" id="f1" method="post" action="search_admin_database.php" onsubmit="return post()">
