jsp页面数据回显（select下拉选择框）详解编程语言

1。静态变量方式：

<!--  
 实现select标签回显  
-->   
1.<select name="curStatus" value="${curStatus}"> <option value="0">-请选择-</option> <option value="1" <c:if test="${'1' eq curStatus}">selected</c:if> >男</option> <option value="2" <c:if test="${'2' eq curStatus}">selected</c:if> >女</option> </select> 

2。动态方式：两个变量都来自后台

<c:set  var="schoolid" value="${pageData.SchoolId}" scope="request"/> <select name="schoolId" id="schoolId" style="width: 95%"> <option value="0">==请选择==</option> <c:forEach items="${organizeList}" var="var" varStatus="vs"> <option value="${var.name_code}" <c:if test="${var.name_code==schoolid}">selected</c:if> > ${var.name}</option> </c:forEach> </select>

说明一下：若是想2那种，实质上是比较两个对象的属性值，不能写成如下：

<select name="schoolId" id="schoolId" style="width: 95%"> <option value="0">==请选择==</option> <c:forEach items="${organizeList}" var="var" varStatus="vs"> <option value="${var.name_code}" <c:if test="${var.name_code==pageData.SchoolId}">selected</c:if> > ${var.name}</option> </c:forEach> </select>
