layui的多文件列表上传功能前端代码
html页面的代码(注意:引入layui相关的css):
<div class="layui-upload" style="margin-left: 130px"> <button type="button" class=" layui-btn" id="choiceList"><i class="iconfont icon-e645"></i>选择多文件</button> <div class="layui-upload-list layui-upList-minHeight"> <table class="layui-table"> <thead> <tr> <th>文件名</th> <th>大小</th> <th>状态</th> <th>操作</th> </tr> </thead> <tbody id="demoList"> <tr id="upload"> <td>xxx.txt</td> <td>xxxkb</td> <td>等待上传</td> <td><button class="layui-btn layui-btn-xs demo-reload layui-hide">重传</button><button class="layui-btn layui-btn-xs layui-btn-danger demo-delete" disabled>删除</button></td> </tr> </tbody> </table> </div> <!-- <div class="layui-form-item layui-btn-Center"> <div class="layui-input-block text-right"> <button type="button" class="layui-btn layui-btn-xs" id="choiceListAction">开始上传</button> <button class="btn layui-btn layui-btn-xs layui-btn-primary js_close" id="quXiao" type="button">取消</button> </div> </div> --> </div>
js的编写(引入layui相关的js):
layui.use(['upload','form','layer','laydate'], function(){ var $ = layui.jquery ,upload = layui.upload ,form = layui.form; //多文件列表示例 $(function() { var uploadFile = { init: function() { this.upload(); }, //上传文件 upload: function() { layui.use('upload', function() { var $ = layui.jquery, upload = layui.upload; //多文件列表示例 var demoListView = $('#demoList'), uploadListIns = upload.render({ elem: '#choiceList', url: '__PUBLIC__/static/file/uploadFile', accept: 'file', multiple: true, auto: true, bindAction: '#choiceListAction', choose: function(obj) { var files = this.files = obj.pushFile(); //将每次选择的文件追加到文件队列 //读取本地文件 obj.preview(function(index, file, result) { if($('#demoList tr td').eq(0).text() == 'xxx.txt') { $('#demoList').empty(); } var tr = $(['<tr id="upload-' + index + '">', '<td>' + file.name + '</td>', '<td>' + (file.size / 1014).toFixed(1) + 'kb</td>', '<td>等待上传</td>', '<td>', '<button class="layui-btn layui-btn-xs demo-reload layui-hide">重传</button>', '<button class="layui-btn layui-btn-xs layui-btn-danger demo-delete">删除</button>', '</td>', '</tr>' ].join('')); //单个重传 tr.find('.demo-reload').on('click', function() { obj.upload(index, file); }); //删除 tr.find('.demo-delete').on('click', function() { delete files[index]; //删除对应的文件 tr.remove(); uploadListIns.config.elem.next()[0].value = ''; //清空 input file 值,以免删除后出现同名文件不可选 }); demoListView.append(tr); }); }, done: function(res, index, upload) { if(res.code == 0) { //上传成功 var tr = demoListView.find('tr#upload-' + index), tds = tr.children(); tds.eq(2).html('<span style="color: #5FB878;">上传成功</span>'); tds.eq(3).html(''); //清空操作 return delete this.files[index]; //删除文件队列已经上传成功的文件 } this.error(index, upload, res.msg); }, error: function(index, upload, msg) { var tr = demoListView.find('tr#upload-' + index), tds = tr.children(); tds.eq(2).html('<span style="color: #FF5722;">' + msg + '</span>'); tds.eq(3).find('.demo-reload').removeClass('layui-hide'); //显示重传 } }); }); } } uploadFile.init(); }); });
