so-far I have tried everything. 
到目前为止，我已经尝试了一切。 My code is below but when I run it nothing seems to happen, nor do I get any error messages. 我的代码在下面，但是当我运行它时，似乎什么也没有发生，也没有收到任何错误消息。 I'm working with Toad for oracle, so I'm literally hard-coding 我正在与Toad for oracle一起工作，所以我实际上是在进行硬编码

http.p ('<input type="form" method="post" name="idstu" id="idstu" placeholder="e.g. 000123456">');
htp.br;
htp.p (' <input type="submit" onclick="confirmMsg()" value="Submit">');

请尝试删除<input>标记中的type=submit 。

your code would be causing error . 您的代码将导致错误。
<input type="form" method="post" name="idstu" id="idstu" placeholder="e.g. 000123456">
it should be type='text'.And alert should be like : 它应该是type ='text'.alert应该像这样：
alert(field1+"has been unsuspended");
}
</script> <!--must have the habit to close each tag -->

i've got it to work. 我有它的工作。 first of all as @liju mentioned i didn't close the script tag as i have thousands of lines(stupid mistake). 首先，因为@liju提到我没有关闭脚本标签，因为我有数千行（愚蠢的错误）。 2nd i played around with the code again and changed the input types of both field and button. 第二，我再次使用该代码，并更改了字段和按钮的输入类型。 now i do get the alert message. 现在我确实收到警报消息。 Thanks everyone . 感谢大家 。 --working code below. -下面的工作代码。 -- -
htp.p ('<input type="text" method="post" name="idstu" id="idstu" placeholder="e.g. 000123456">');
htp.br;
htp.p (' <input type="button" onclick="confirmMsg()" value="Submit">');
htp.p ('<script type="text/javascript">
function confirmMsg() {
var field1 = document.getElementById("idstu").value;
alert(field1+"has been unsuspended");
}
</script>');
