php程序段里加入js代码,可是ie里也只是显示为js代码,请问是什么原因?
js段程序如下:
<?

echo "<script language='JavaScript' >";
echo "<!--";

echo "//____________________________________________________________";
echo " window.opener.form1.content.value= '123' + window.opener.form1.content.value;";
echo " window.close();";

echo "//____________________________________________________________";
echo "//____________________________________________________________";

echo "//-->";
echo "</script>";


?>

<?php

echo "<script language='JavaScript' >";

echo " window.opener.form1.content.value= '123' + window.opener.form1.content.value;";
echo " window.close();";

echo "</script>";


?>

呵呵，是echo "//____________________________________________________________";里没有输出换行符"\n"吧。

不可能！！！


写成这样看看
<?

echo <<< JS
<script language='JavaScript' >
<!--

//____________________________________________________________
window.opener.form1.content.value= '123' + window.opener.form1.content.value;
window.close();

//____________________________________________________________
//____________________________________________________________

//-->
</script>
JS;


?>

<script language='JavaScript'>;
<!--;

//____________________________________________________________;
window.opener.form1.content.value= '123' + window.opener.form1.content.value;";
window.close();;

//____________________________________________________________;
//____________________________________________________________;

//-->;
</script>;

js对换行是有要求的，//_______\n\r; 这样就可以了
