一、文件上传前端
<div>
<div class="layui-upload" align="left">
<fieldset class="layui-elem-field layui-field-title" style="margin-top: 30px;">
<legend>请选择您要上传的文件</legend>
</fieldset>
<div class="layui-upload-list">
<table class="layui-table">
<thead>
<div class="layui-form-item">
<div>
<label class="layui-form-label"> 文件名：</label>
<div class="layui-inline">
<input class="layui-input" name="name" id="name" autocomplete="off"
placeholder="请输入文件名">
</div>
描述：
<div class="layui-inline">
<input class="layui-input" name="description" id="description" autocomplete="off"
placeholder="请输入描述">
</div>
</div>
</div>
<tr style="margin-left: 50px">
<th>文件名</th>
<th>大小</th>
<th>状态</th>
<th>操作</th>
</tr>
</thead>
<tbody id="demoList"></tbody>
</table>
</div>
<div align="center">
<button type="button" class="layui-btn layui-btn-normal" id="testList">选择文件</button>
<button type="button" class="layui-btn" id="testAction">开始上传</button>
</div>
</div>
</div>
二、layui代码
layui.use('upload', function () {
var $ = layui.jquery
, upload = layui.upload;
//多文件列表
var demoListView = $('#demoList')
, uploadListIns = upload.render({
elem: '#testList'
, url: ctxPath + 'xxxContrller/uploadFile/'
, accept: 'file'
, multiple: true
, auto: false
, size: 51200
, bindAction: '#xxAction'
, before: function () {
/*return false;
console.log("add->" + id + "-" + r);
alert("ft->" + fileTypeId);
layer.msg("请选择文件类型！", {icon: 1, time: 1000});
if (fileTypeId == null && fileTypeId == '' && fileTypeId == "") {
}*/
this.data = {
"name": $("#name").val(),
"xxId": xxId
};
}
, 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) {
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-mini demo-reload layui-hide">重传</button>'
, '<button class="layui-btn layui-btn-mini 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) {
debugger;
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
} else if (res.code == 2) {
layer.msg("请选择文件类型！", {icon: 5, time: 1000});
}
this.error(index, upload);
}
, error: function (index) {
debugger;
var tr = demoListView.find('tr#upload-' + index)
, tds = tr.children();
tds.eq(2).html('<span style="color#FF5722;">上传失败1</span>');
tds.eq(3).find('.demo-reload').removeClass('layui-hide'); //显示重传
}
});
});
