先看一段代码(PHP例子)
1、表单代码(form.php):
[php] view plaincopy
<?php
header("Content-type: text/html; charset=utf8");
?>
<iframe name="testIframeName" style="display:none;"></iframe>
<form target="testIframeName" method="post" action="formAction.php">
<input type="text" name="username"/>
<input type="password" name="password"/>
<input type="submit" value=" 提 交 " />
</form>
2、action代码(formAction.php):
[php] view plaincopy
<?php
echo "<script>alert(‘test....‘);</script>";
?>
