前端的IF语句很实用
前端的if语句可以用于权限的解决方案
需求:chebox选择按钮有值传入的时候,显示的是值的数据,没有值或者新建的数据显示页面上的值。
<div class="controls"> 是 <form:radiobutton path="defaultSelection" name="gender" value="1" htmlEscape="false" style="width:10px;" maxlength="125" class="required"/> 否<c:if test="${empty ocDevopsScore.defaultSelection}"> <form:radiobutton path="defaultSelection" name="gender" value="0" checked="checked" htmlEscape="false" style="width:10px;" maxlength="125" class="required"/> </c:if> <c:if test="${not empty ocDevopsScore.defaultSelection}"> <form:radiobutton path="defaultSelection" name="gender" value="0" htmlEscape="false" style="width:10px;" maxlength="125" class="required"/> </c:if> </div>
判断相等执行的语句
<c:if test="${dict.level == 5}"> <a href="${ctx}/oc/devopsscore/list?devopsTypeId=${dict.id}">[scoreList]</a> </c:if> 可以这样写判断 进行跳框提示 <a href="${ctx}/oc/scope/delete?id=${dict.id}&type=${dict.type}" onclick="return confirmx('Do you want to delete the scope?', this.href)">[delete]</a>
需求:判断登录的user是否有权限修改,自己只能修改自己的数据,超级管理院员就能修改全部的数据。
<c:choose> <c:when test="${fns:getUser().id eq dict.createBy.id}"> <a href="${ctx}/ito/projectinfo/delete?id=${dict.id}" onclick="return confirm('Do you want to delete the record?', this.href)">[delete]</a> </c:when> <c:otherwise> <shiro:hasAnyRoles name="system"> <a href="${ctx}/oc/projectinfo/delete?id=${dict.id}" onclick="return confirm('Do you want to delete the record?', this.href)">[delete]</a> </shiro:hasAnyRoles> </c:otherwise> </c:choose>
