在tomcat中,执行jsp既不报错，也不显示，不是异常捕获的问题
下面是jsp代码
<%@page contentType= "text/html; charset=GBK " %>
<html>
<head>
<title> 呆呆 </title>
<script>
alert( "javascript ");
function show(){
var oForm = document.form1;
var oText = oForm.currentPage;
var oText1 = oForm.rowNum;
alert(oText.value);
alert(oText1.value);
oForm.submit();
}
</script>
</head>
<body onload= "javascript:alert( ' enter body ') ">
<%
int currentPage = 0;
int rowNum = 0;
int page1 = 0;
out.println( "currentPage === "+currentPage);
out.println( "rowNum === "+rowNum);
currentPage++;
rowNum++;
page1 ++;
/*
if(page1 = null){
page = 1;
}
else{
page = Integer.parseInt(page1);
}
out.print( "page === "+page1);
*/
%>
<table>
<form name= "form1 ">
<input type= "text " name = "currentPage " value = " <%= currentPage %> " />
<input type= "text " name = "rowNum " value = " <%= rowNum %> " />
<input type= "button " name = "button1 " value = "下一页 " onclick= "show() " />
<a href= "send.jsp?page= <%= page1+1 %> "> xia </a>
</form>
</table>
</body>
</html>
这个是没错的，但是随便改错一个，就既不报错，也不显示
请问是怎么回事情？？？？？？？？？？
[解决办法]
看tomcat的logs目录下的log日志错误记录找错误
[解决办法]
同意1楼的，看看log日志里的记录

你应当这样
<html>
<head>
<title> 呆呆 </title>
<script>
alert( "javascript ");
function show(){
var oForm = document.form1;
var oText = oForm.currentPage;
var oText1 = oForm.rowNum;
alert(oText.value);
alert(oText1.value);
oForm.submit();
}
</script>
</head>
<body onload= "javascript:alert( ' enter body ') ">
<%
int currentPage = 0;
if(request.getParameter( "currentPage ") != null)
{
currentPage = Integer.parseInt(request.getParameter( "currentPage "));
}
int rowNum = 0;
int page1 = 0;
out.println( "currentPage === "+currentPage);
out.println( "rowNum === "+rowNum);
currentPage++;
rowNum++;
page1 ++;
/*
if(page1 = null){
page = 1;
}
else{
page = Integer.parseInt(page1);
}
out.print( "page === "+page1);
*/
%>
<form name= "form1 ">
<input type= "text " name = "currentPage " value = " <%= currentPage %> " />
<input type= "text " name = "rowNum " value = " <%= rowNum %> " />
<input type= "button " name = "button1 " value = "下一页 " onclick= "show() " />
<a href= "send.jsp?page= <%= page1+1 %> "> xia </a>
</table>
</body>
</html>
