EL表达式判断条件要写在${}内

由于老没开发框架了，今天提取公共省市县三级联动组件时，使用jsp传参搞了半天才弄出来。

组件代码

 $(function(){console.log("${param.init}");
         <c:if test="${param.init}">
             <c:if test="${not empty data && not empty data.province}">
                 var address = {
                     province : "${data.province}",
                     city : "${data.city}",
                     coll : "${data.coll}",
                     detailAddress : "${data.detailAddress}"
                 };
             </c:if>
             setAddress(address);
         </c:if>
     });
     function setAddress(address) {
         window.initSelect(1, 'province','${adminPath}/basic/usualaddress/regionSelect');
         if(address && address.province) {
             window.$("#province").val(address.province);
             window.changCity('${adminPath}/basic/usualaddress/regionSelect');
             window.$("#city").val(address.city);
             window.changColl('${adminPath}/basic/usualaddress/regionSelect');
             window.$("#coll").val(address.coll);
             window.$("#detailAddress").val(address.detailAddress);
         }
     }

调用

 <jsp:include page="../../common/address.jsp">
     <jsp:param name="init" value="true" />
 </jsp:include>

EL表达式判断规范

test="${条件要写在大括号里面}"

错误案例：test="${param.init} == true";

应为：test="${param.init == true}";
