java - Split a jsp method in multiple scriplets to include html code in between

Question

I am writing a method in JSP which dump rows of a table:

<%!  
    void dumpRows(List<MyClass> obList){  
        int a = 10;  
        for(int i = 0; i<100; i++){  
%>  
   //lots of HTML code which uses the variables from the dumpRows method  
   <td> <%=a*i%> </td>  
<%  
        }//for loop ends  
    }//method ends  
%>  

but it is erroring out. There's something wrong with the JSP grammar. Please help me on how can I achieve that

Answer 1

<%!  
    void dumpRows(List<MyClass> obList){  
        int a = 10;  
        for(int i = 0; i<100; i++){  
%>  
   //lots of HTML code which uses the variables from the dumpRows method  
   <td> <%=a*i%> </td>                 //here problem
<%  
        }//for loop ends  
    }//method ends  
%>

这样写打印 <%=a*i%>

我认为问题在于您正在混合<%!，<%并且<%=.
如果你将业务逻辑和视图分开，它会更容易和清晰。
您可以使用 JSTL 标签<c:forEach>来输出您的 html 表格。
