layui获取select下拉框选中的option的值
使用javascript原生的方法
表单如下
注意需要加上lay-filter="status"
<form class="layui-form" action="">
<div class="layui-form-item">
<label class="layui-form-label">状态:</label>
<div class="layui-input-inline" style="width:100px">
<select id='status' name="status" layui-verify="required" lay-filter="status" >
<option value='0' <c:if test='${demo.status == 0}'>selected</c:if>>无效</option>
<option value='1' <c:if test='${demo.status == 1}'>selected</c:if>>有效</option>
</select>
</div>
</div>
</form>
js取值
<script type="text/javascript">
layui.use('form', function(){
var form = layui.form;
form.on('select(status)', function(){
//1:拿到select对象:
var myselect=document.getElementById("status");
//2:拿到选中项的索引:
var index=myselect.selectedIndex ; // selectedIndex代表的是你所选中项的index
//3:拿到选中项options的value:
console.log(myselect.options[index].value);
//4:拿到选中项options的text:
console.log(myselect.options[index].text);
});
});
</script>
