layui如何获取复选框的值以及如何为复选框赋值-Layui教程

获取复选框的值：

（学习视频分享：javascript视频教程）

一、layui获取单个复选框的值

=========================================HTML=============================================<div class="layui-form-item">   <div class="layui-col-md12">         <div>               <label class="layui-form-label">类型</label>               <div class="layui-input-block">                    <input type="checkbox" name="AllDay" id="AllDay" lay-filter="test1" value="全天" title="全天">                    <input type="checkbox" name="IsEnd" id="IsEnd" lay-filter="test1" value="结束时间" title="结束时间">               </div>         </div>        <span></span>   </div></div>========================================JS=============================================var allDayCheck = document.getElementById("AllDay").checked;var isEndCheck = document.getElementById("IsEnd").checked;

二、layui获取多个复选框的值，并集中传给后台

//HTML代码<form class="layui-form">    <div class="layui-form-item">        <label class="layui-form-label">复选框</label>        <div class="layui-input-block">            <input type="checkbox" name="like" value="1" title="写作">            <input type="checkbox" name="like" value="2" title="阅读" >            <input type="checkbox" name="like" value="3" title="发呆">        </div>    </div>    <div class="layui-form-item">        <div class="layui-input-block">            <button class="layui-btn" lay-submit lay-filter="formDemo">立即提交</button>            <button type="reset" class="layui-btn layui-btn-primary">重置</button>        </div>    </div></form> //JS代码<script>    layui.use('form', function(){        var form = layui.form;        form.on('submit(formDemo)', function(data){            //获取checkbox[name='like']的值            var arr = new Array();            $("input:checkbox[name='like']:checked").each(function(i){                arr[i] = $(this).val();            });            data.field.like = arr.join(",");//将数组合并成字符串            $.post("admin.php", {data:data.field}, function (res) {                if (res.code == 1) {                    layer.msg(res.msg, {time: 1800, icon: 1}, function () {                        location.href="https://zhishitu.com/ke"                    });                } else {                    layer.msg(res.msg, {time: 1800, icon: 2});                }            }, 'json');            return false;        });    });</script>

那么怎么给layui复选框赋值呢？

 layui.use('form', function () {     form = layui.form;     $('#AllDay').prop("checked", true); //先进行基本赋值                               form.render(); //这句必须（用来更新渲染页面）});
