我有这个简单的代码:
<?
if (isset($_POST["phpinfo"])) phpinfo(); else echo "you haven't chosen what to do yet";
?>
<h1>Test page 1</h1>
<form method="post" action="">
<select>
<option>Choose what to do</option>
<option value='phpinfo'>phpinfo();</option></select></form>
问题是,如果我使用JavaScript(onChange =“this.form.submit()”)来自动提交帖子数据,它就不会提交,但如果我使用提交按钮,它会提交给自己。< / p>
<input type="submit" name='phpinfo' id="phpinfo">
我的问题是,我该怎么办?我可以有一个自动提交下拉列表,将POST数据提交给自己?
提前致谢!

您的选择需要命名。选择名称是返回给PHP的名称,其值将是所选选项的值。
<select name="performaction">
<option value="phpinfo">phpinfo ()</option>
</select>
if ($_POST [performaction] == 'phpinfo')
{
phpinfo ();
}

<?php
if($_POST['txtVal'] != "") {
echo "Form Submited";
}
?>
<form method="post" action="">
<select name="txtVal" onchange="this.form.submit();">
<option>Choose what to do</option>
<option value='phpinfo'>phpinfo();</option></select>
</form>
希望它适合你。

尝试:
//add a name to form
<form method="post" action="" name="some_name">
//then on your select's onchange function do:
document.forms['some_name'].submit();
