1 手动上传
上传文件分为两步，第一步选择文件，第二步上传文件。
HTML代码：
<input type='button' id='selectFile' value='选择文件'><div id='fileDiv'></div><input type='button' id='uploadFile' value='上传文件'>
JS代码：
$(function(){initUpload();});//初始化上传组件function initUpload(){layui.use(['upload'], function () {var upload = layui.upload;//单文件上传upload.render({elem: '#selectFile',url: "upload.aspx",accept: 'file',multiple: false,auto: false,size: 50 * 1024,//单位kbbindAction: '#uploadFile',choose: function (obj) {obj.preview(function (index, file, result) {$("#fileDiv").val(file.name);});},done: function (res, index, upload) {if (res.Code == 1) { //上传成功alert("上传成功");}else {alert("上传失败！");}},error: function (index, upload) {alert("上传失败！");}});});}
2 自动上传
选择文件时自动上传文件。
HTML代码：
<input type='button' id='selectFile' value='选择文件'><div id='fileDiv'></div>
JS代码：
$(function(){initUpload();});//初始化上传组件function initUpload(){layui.use(['upload'], function () {var upload = layui.upload;//单文件上传upload.render({elem: '#selectFile',url: "upload.aspx",accept: 'file',multiple: false,auto: true,//是否自动上传，true自动上传,false手动上传size: 50 * 1024,//单位kbchoose: function (obj) {obj.preview(function (index, file, result) {$("#fileDiv").val(file.name);});},done: function (res, index, upload) {if (res.Code == 1) { //上传成功alert("上传成功");}else {alert("上传失败！");}},error: function (index, upload) {alert("上传失败！");}});});}
