一、c标签

if…else…

<c:choose>                <c:when test="${shopProduct == ''}">                    <input type="hidden" class="form-control" name="productid" value="">                   </c:when>                   <c:otherwise>                    <input type="hidden" class="form-control" name="productid" value="${shopProduct.productid }">                </c:otherwise>            </c:choose>

select

<select id="cateid" name="cateid" class="form-control" style="width:205px">                              <option value="">---请选择---</option>                                <c:forEach items="${shopCategoryList}" var="shopCategoryList" varStatus="row">         <c:choose>             <c:when test="${shopCategoryList.cateid eq shopProduct.cateid}">              <option value="${shopCategoryList.cateid}" selected="selected">${shopCategoryList.title }</option>            </c:when>            <c:otherwise>              <option value="${shopCategoryList.cateid}">${shopCategoryList.title}</option>            </c:otherwise>             </c:choose>           </c:forEach>                               </select>

radio

<c:if test="${shopProduct.issale=='1'}">                     <input checked="checked" type="radio" class="form-control" name="issale" id="issale1" value="1"> <label for="issale1" style="display: inline;">是</label>                      <input type="radio" class="form-control" name="issale" id="issale0" value="0"> <label for="issale0" style="display: inline;">否</label>                      </c:if>                     <c:if test="${shopProduct.issale=='0'}">                     <input type="radio" class="form-control" name="issale" id="issale1" value="1"> <label for="issale1" style="display: inline;">是</label>                      <input checked="checked" type="radio" class="form-control" name="issale" id="issale0" value="0"> <label for="issale0" style="display: inline;">否</label>                      </c:if>

使用以下方式，需要注意数据库存储的类型不要是char，enum

<input type="radio" name="emp.sex" value="1" <c:if test="${info.sex=='1'}" 'checked'/>/>男<input type="radio" name="emp.sex" value="1" <c:if test="${info.sex==0}" 'checked'/>/>女
