<?php
$test = $_POST[ 'test '];
echo '12 ';
echo $test;
echo $_POST[ 'submit1 '];
echo $_POST[ 'submit2 '];
if (isset($_POST[ 'submit1 ']) && $_POST[ 'submit1 '] == 'submit1 ')
{
echo 'ok1 ';
}
if (isset($_POST[ 'submit2 ']) && $_POST[ 'submit2 '] == 'submit2 ')
{
// echo " <meta http-equiv=refresh content= '0; url=http://localhost:8000/php/index.php '> ";
// header( "Location:index.php ");
// break;
echo 'ok2 ';
}
?>
代码如下:
<html>
<head> </head>
<body>
<form action= 'xajaxtest.php ' method= 'POST '>
<input type= 'hidden ' name= 'test ' value= 'test1 '>
<input name= 'submit1 ' type= 'submit ' value= 'submit1 ' title= 'submit1 '>
<input name= 'submit2 ' type= 'submit ' value= 'submit2 ' title= 'submit2 '>
</form>
</body>
</html>
为什么 这个测试页面 载入后第一次不传数据?
echo $_POST[ 'submit1 '];echo $_POST[ 'submit2 '];都打印空
之后就好了。这个是什么原因 有没有办法解决?
方法二:
<script language= "JavaScript "><!--
function check(){
frm.action = "checkname.php "
}
function mysubmit() {
frm.action = "zhuce.php "
}
// --></script>
<form method=post action= " " name= "frm ">
<input type= "submit " onclick= "check() ">
<input type= "submit " onclick= "mysubmit() ">
</form>
