layui 记录1

　　目前所做项目很多控件及其数据表格用到layui,整理一下，以后查阅。

　　首先数据表格：

　　页面Html代码：

　　　　

 <table id="Table" lay-filter="layfilter" ></table>
    <script type="text/html" id="toolbarDemo">
        搜索：
        <div class="layui-inline">
            <input class="layui-input" name="id" id="txtSearch" autocomplete="off">
        </div>
        <button class="layui-btn layui-btn-sm" lay-event="btnSearch">搜索</button>
        <button class="layui-btn layui-btn-sm" lay-event="btnAddNew">添加新</button>
        <button class="layui-btn layui-btn-sm" lay-event="btnDelCheck">删除选中行</button>   
    </script>
    <script type="text/html" id="barDemo">
        <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
        <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
    </script>

　　js代码：

layui.use("table", function () {
    var table = layui.table;
    table.render({
        elem: "#Table"  //页面中的Id
        , id: "ExpertListTableID"   //防止重复id
        , method: "get"
        , url: GetAPIUrl("api/Expert/GetList")
        , where: { "参数": 参数 }  //json传参格式
        , toolbar: "#toolbarDemo"  //头部导航编辑栏 Id
        , title: "标题"
        , page: ListTablePage
        , response: {
            statusCode: "ok" //重新规定成功的状态码为 ok，table 组件默认为 0
        }
        /*, request: {
            pageName: 'curr' //页码的参数名称，默认：page
            , limitName: 'nums' //每页数据量的参数名，默认：limit
        }
        ,  1024
        , height: 500
        , parseData: function (res) { //将原始数据解析成 table 组件所规定的数据    这个就是后台返回的数据
            return {   //返回数据
                "code": res.status, //解析接口状态
                "msg": res.message, //解析提示文本
                "count": res.total, //解析数据长度
                "data": res.rows.item //解析数据列表
            };
        }*/
        , cols: [[
            { type: "checkbox", fixed: "left" }
            , { type: "numbers", title: "序号"}
            , { field: "lieming1", title: "列名1", sort: true }
            , { field: "lieming2", title: ""}
            , { field: "lieming3", title: ""}

            , { fixed: "right", title: "操作", toolbar: "#barDemo"}
        ]]
    });

    //这里以搜索为例   这是重载table
    //table.reload({
    //    where: {"uid":""} //设定异步数据接口的额外参数
    //    , page: {
    //        curr: 1 //重新从第 1 页开始
    //    }
    //});


    //头工具栏事件

        }
    });
    return b;
}

　　

　　编辑页面：

　　首先就是页面赋值

　　html页面：

<form id="form1" class="layui-form" lay-filter="formFilter">
这里是编辑页面 里面的表单 

下面 是上传图片功能

<div class="layui-form-item">
<label class="layui-form-label">照片</label>
<div class="layui-input-block">
<button type="button" class="layui-btn" id="expert_photo_up"><i class="layui-icon">&#xe67c;</i>上传照片</button>
<button type="button" class="layui-btn" id="expert_photo_view">查看照片</button>
<label id="demoText"></label>
<div class="layui-input-inline">
<input type="hidden" id="expert_photo" name="expert_photo" class="layui-input">
</div>
<img class="layui-upload-img" id="photoimg" name="photoimg" style="295px;height:413px;display:none">
</div>
</div>

</form>

注意 一定要 用form，因为 layui需要form进行渲染

　　js页面：

　　

layui.use(['form', 'layedit', 'laydate', 'upload'], function () {
    var form = layui.form
        , layer = layui.layer
        , laydate = layui.laydate;
    var upload = layui.upload;

    //上传设置  
    var uploadInst = upload.render({
        elem: '#expert_photo_up' //绑定元素
        , url: GetAPIUrl("api/FileUpload/ImgUpload") //上传接口
        , method: "POST"
        , before: function (obj) {
            //预读本地文件示例，不支持ie8
            obj.preview(function (index, file, result) {
                $('#photoimg').attr('src', result); //图片链接（base64）
            });
        }
        , done: function (msg) {
            if (msg.code == "ok") {
                layer.msg(msg.msg);
                $('#expert_photo').val(msg.url);
                $('#photoimg').attr('src', GetAPIUrl(msg.url));
                //$("#expert_photo_view").click();
            }
            else {
                layerAlert("上传失败！");
            }
        }
        , error: function () {
            //请求异常回调
            //演示失败状态，并实现重传
            var demoText = $('#demoText');
            demoText.html('<span style="color: #FF5722;">上传失败</span> <a class="layui-btn layui-btn-xs demo-reload">重试</a>');
            demoText.find('.demo-reload').on('click', function () {
                uploadInst.upload();
            });
        }
    });
//对于日期的渲染 有多少个Id就渲染多少个
    //日期渲染
    laydate.render({
        elem: '#expert_birthdate'
    });
    //日期渲染
    laydate.render({
        elem: '#expert_starttime_quantum'
    });
    //日期渲染
    laydate.render({
        elem: '#expert_endtime_quantum'
    });

    //监听提交
