PHP
<?php if (isset($_POST["sub"])) { // dosomething() }?><html><form id="form1" name="form1" method="post" action=""> <br><input type="text" name="name"> <br><input type="text" name="shool"> <input type="submit" name="sub" value="loginBtn"></form></html>
使用输出流?
这样的用php什么,直接用js就ok了
<html><script type="text/javascript"> function wokao(){ var name = document.getElementsByName("name")[0].value; document.getElementsByName("shool")[0].value=name; return false;}</script><form id="form1" name="form1" method="post" action="" onsubmit="return wokao();"> <br><input type="text" name="name"> <br><input type="text" name="shool"> <input type="submit" name="sub" value="loginBtn"></form></html>
