jsp页面使用if else语句

jsp页面嵌入java语句使用<%%>即可,但是在使用if else语句时一定要注意使用是标点的使用,在语句中分号不能写,不符合jsp页面的语法规则,若多写了则会报错:如下:

<% if(retailerLevel.equals("A")) {%> {name: 'priceRA', type: 'string'}, <%;} %>
<% else if(retailerLevel.equals("B")) {%> {name: 'priceRB', type: 'string'}, <%;} %>
<% else if(retailerLevel.equals("C")) {%> {name: 'priceRC', type: 'string'},<%;} %>
<% else if(retailerLevel.equals("D")) {%> {name: 'priceRD', type: 'string'},<%;} %>
<% if(retailerLevel.equals("A")) {%> {name: 'priceFA', type: 'string'},<%;} %>
<% else if(retailerLevel.equals("B")) {%> {name: 'priceFB', type: 'string'},<%;} %>
<% else if(retailerLevel.equals("C")) {%> {name: 'priceFC', type: 'string'},<%;} %>
<% else if(retailerLevel.equals("D")) { %> {name: 'priceFD', type: 'string'},<%;} %>

则会报很多相关else的错误,但是若把分号去掉则ok了!!如换成以下代码则会正常运行:

<% if(retailerLevel.equals("A")) {%> {name: 'priceRA', type: 'string'},
<%} else if(retailerLevel.equals("B")) {%> {name: 'priceRB', type: 'string'},
<%} else if(retailerLevel.equals("C")) {%> {name: 'priceRC', type: 'string'},
<%} else if(retailerLevel.equals("D")) {%> {name: 'priceRD', type: 'string'},
<%} if(retailerLevel.equals("A")) {%> {name: 'priceFA', type: 'string'},
<%} else if(retailerLevel.equals("B")) {%> {name: 'priceFB', type: 'string'},
<%} else if(retailerLevel.equals("C")) {%> {name: 'priceFC', type: 'string'},
<%} else if(retailerLevel.equals("D")) { %> {name: 'priceFD', type: 'string'},<%} %>
