Layui动态生成select下拉选择框不显示的解决方法
给代码添加如下部分:
layui.use('form', function(){ //此段代码必不可少 var form = layui.form; form.render(); });
实现效果:
HTML代码:
<div class="layui-form-item"> <label class="layui-form-label">执行周期</label> <div class="layui-input-inline" style="width: 90px;"> <select name="period_type" lay-verify="required" lay-filter="period"> <option value="week">每星期</option> <option value="day">每天</option> <option value="day-n">N天</option> <option value="hour">每小时</option> <option value="hour-n">N小时</option> <option value="minute-n">N分钟</option> <option value="month">每月</option> </select> </div> <div id="suboption"> <!-- 默认每星期 --> <div> <div class="layui-input-inline" style="width: 90px;"> <select name="week"> <option value="1">周一</option> <option value="2">周二</option> <option value="3">周三</option> <option value="4">周四</option> <option value="5">周五</option> <option value="6">周六</option> <option value="0">周日</option> </select> </div> <div class="layui-input-inline" style="width: 60px;"> <input type="number" name="hour" value="1" max="23" maxlength="2" min="0" class="layui-input"/> </div> <div class="layui-input-inline" style="width: 50px; vertical-align: middle; margin-left: -11px;"> <input type="text" class="layui-input" readonly value="小时" style=" background-color: #f6f6f6;"> </div> <div class="layui-input-inline" style="width: 60px;"> <input type="number" name="minute" value="30" maxlength="2" max="59" min="0" class="layui-input"/> </div> <div class="layui-input-inline" style="width: 50px; vertical-align: middle; margin-left: -11px;"> <input type="text" class="layui-input" readonly value="分钟" style=" background-color: #f6f6f6;"> </div> </div> </div> </div>
