<html> 
<head> </head> 
<body> 
<form action= &#39;xajaxtest.php &#39; method= &#39;POST &#39;> 
<input type= &#39;hidden &#39; name= &#39;test &#39; value= &#39;test1 &#39;> 
<input name= &#39;submit1 &#39; type= &#39;submit &#39; value= &#39;submit1 &#39; title= &#39;submit1 &#39;> 
<input name= &#39;submit2 &#39; type= &#39;submit &#39; value= &#39;submit2 &#39; title= &#39;submit2 &#39;> 
</form> 
</body> 
</html> 
为什么 这个测试页面 载入后第一次不传数据？ 
echo $_POST[ &#39;submit1 &#39;];echo $_POST[ &#39;submit2 &#39;];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>
Copy after login
