在JSP中声明函数？
在JSP中声明函数？
提问于 2009-05-05 21:13:34
我来自PHP世界，在php页面中间声明一个函数是非常简单的。我试着在JSP中做同样的事情：
public String getQuarter(int i){
String quarter;
switch(i){
case 1: quarter = "Winter";
break;
case 2: quarter = "Spring";
break;
case 3: quarter = "Summer I";
break;
case 4: quarter = "Summer II";
break;
case 5: quarter = "Fall";
break;
default: quarter = "ERROR";
}
return quarter;
}我得到以下错误：
An error occurred at line: 20 in the jsp file: /headers.jsp
Illegal modifier for the variable getQuarter; only final is permitted return;回答 1

您需要将其包含在<%！%>中，如下所示：
<%!
public String getQuarter(int i){
String quarter;
switch(i){
case 1: quarter = "Winter";
break;
case 2: quarter = "Spring";
break;
case 3: quarter = "Summer I";
break;
case 4: quarter = "Summer II";
break;
case 5: quarter = "Fall";
break;
default: quarter = "ERROR";
}
return quarter;
}
%>然后，可以在scriptlet或表达式中调用该函数：
<%
out.print(getQuarter(4));
%>或
<%= getQuarter(17) %>页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
