浅谈layui文件上传、预览及修改

本篇文章和大家浅谈一下layui文件单文件和多文件的上传、预览以及删除和修改。有一定的参考价值,有需要的朋友可以参考一下,希望对大家有所帮助。

单文件上传

1、HTML

<blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px;">
<div id="uploadQRcode" class="layui-upload">
    <button type="button" class="layui-btn" id="uploadQR">
        <i class="layui-icon">&#xe67c;</i>上传客服二维码
        <span style="color: red;font-size: 20px;">*</span>
    </button>
    <div class="layui-upload-list">
        <img id="qrshow" src="" alt="" class="layui-upload-img"
             style="height: 100px;width:100px;border:1px solid black;">
    </div>
    <div id="startDiv">
        <button type="button" class="layui-btn" id="startUploadQR">开始上传</button>
    </div>
    <div style="color: #c2c2c2;margin:10px 0;">
    温馨提示: 每次最多上传一张图片, 单张图片的大小不超过2MB
    </div>
</div>
<input type="text" name="cli_qrcode" id="qrInput" style="display:none;"
 lay-verify="required">
</blockquote>

2、js部分

var form = layui.form;
var element = layui.element;
var $ = layui.jquery;
var upload = layui.upload;

//单文件示例  选完文件后不自动上传
var uploadSingle = upload.render({
    elem: '#uploadQR'
    , url: '/web/api/upload/upload?option=4'
    , accept: 'images'  // 允许上传的文件类型
    , size: 2048     // 最大允许上传的文件大小  单位 KB
    , auto: false
    , bindAction: '#startUploadQR'
    , choose: function (obj) {
        //预读本地文件示例,不支持ie8
        obj.preview(function (index, file, result) {
            $('#qrshow').attr('src', result); //图片链接(base64)
        });
    }
    , done: function (res, index, upload) {
        if (res.code == 0) {
            //上传成功
            $("#qrInput").val(res.data[0].fp_relative);
            var startDiv = $('#startDiv');
            startDiv.html('<span style="color: #5FB878;">
            上传成功
            </span>');
        } else {
            this.error(index, upload);
        }
    }
    , error: function (index, upload) {
        //演示失败状态,并实现重传
        var startDiv = $('#startDiv');
        startDiv.html('<span style="color: #FF5722;">上传失败</span> 
        <a class="layui-btn layui-btn-xs demo-reload" style="width:50px;
                  height:30px;text-align:center;line-height:30px;">重试</a>');
        startDiv.find('.demo-reload').on('click', function () {
            uploadSingle.upload();
        });
    }
});

多图片的上传

1、HTML

<blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px;">
<div id="uploadImg" class="layui-upload">
<button type="button" class="layui-btn" id="upload">
    <i class="layui-icon">&#xe67c;</i>上传商铺图片
    <span style="color: red;font-size: 20px;">*</span>
</button>
<div class="layui-upload-list">
    <table class="layui-table" style="text-align: center;">
        <thead>
        <tr>
            <th style="text-align: center;">图片预览</th>
            <th style="text-align: center;">大小</th>
            <th style="text-align: center;">状态</th>
            <th style="text-align: center;">操作</th>
        </tr>
        </thead>
        <tbody id="imgList"></tbody>
    </table>
</div>
<button type="button" class="layui-btn" id="startUpload">开始上传</button>
    <div style="color: #c2c2c2;margin:10px 0;">
    温馨提示: 每次最多上传六张图片, 单张图片的大小不超过5MB, 长宽比例推荐1.5:1,
        推荐上传图片长675px,宽450px
    </div>
</div>
<input type="text" name="face_img" id="imgInput" style="display:none;"
