jsp 页面问题请帮帮忙!
报错问题:
java.lang.NumberFormatException: For input string: " 1"
我做页面跳转的时候接受参数就报了上边的错误,请明白的人帮忙解答一下,谢谢啦.
源代码:
<%
int id = Integer.parseInt(request.getParameter("id"));
int rootId = Integer.parseInt(request.getParameter("rootid"));
%>
<html>
<head>
</head>
<body>
<form action="ReplyOk.jsp" method="post">
<input type="hidden" name="id" value="<%=id%>">
<input type="hidden" name="rootid" value="<%=rootId %>">
<table border="1">
<tr>
<td>
<input type="text" name="title" size="80">
</td>
</tr>
<tr>
<td>
<textarea cols="80" rows="12" name="cont"></textarea>
</td>
</tr>
<tr>
<td>
<input type="submit" value="提交">
</td>
</tr>
</table>
</form>
</body>
</html>
[解决办法]
request.getParameter("rootid")改为request.getParameter("rootid").trim()
request.getParameter("id")改为request.getParameter("id").trim()
