<input type='button' id='selectFile' value='选择文件'>
<div id='fileDiv'></div>
<input type='button' id='uploadFile' value='上传文件'>
$(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kb
bindAction: '#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！");
}
});
});
}
