最近搞个判断是否阻止,网上搜了些,可以用,但是就不能延迟上传了,研究了下代码,这样写就能先选中再上传了
打开upload搜索y = function () 之后注释原代码,加入
if ("choose" !== i &&!l.auto || (l.choose &&l.choose(g), "choose" !== i))return "choose" === t ? l.choose &&l.choose(g) : ((l.before &&l.before(g)) === false ? '' : a.ie ? a.ie >9 ? u() : c() : void u())

最后就这样了
y = function () { if ("choose" !== i &&!l.auto || (l.choose &&l.choose(g), "choose" !== i))return "choose" === t ? l.choose &&l.choose(g) : ((l.before &&l.before(g)) === false ? '' : a.ie ? a.ie >9 ? u() : c() : void u())/*if("choose"!==i&&!l.auto||(l.choose&&l.choose(g),"choose"!==i))return l.before&&l.before(g),o.ie?o.ie>9?u():c():void u()*/}

在 before 回调里面 执行追加 隐藏input的 *** 作，里面放你的参数 $('.layui-upload-file').after( '<input type="hidden" name="xxxx" value="xxxx" />' )<!DOCTYPE html><html> <head> <meta charset="UTF-8"> <title>文件上传</title> <link rel="stylesheet" href="layui/css/layui.css"> <link rel="stylesheet" href="css/global.css"> </head> <body> <fieldset class="layui-elem-field layui-field-title" style="margin-top: 20px"> <legend>设定上传文件的格式</legend> </fieldset><input type="file" name="file" class="layui-upload-file"><input type="file" name="file1" lay-type="file" class="layui-upload-file"><input type="file" name="file1" lay-type="audio" class="layui-upload-file"><input type="file" name="file2" lay-type="video" class="layui-upload-file"><blockquote class="layui-elem-quote" style="margin-top: 20px">支持拖动文件上传</blockquote><fieldset class="layui-elem-field layui-field-title" style="margin-top: 50px"> <legend>演示上传</legend> </fieldset> <div class="site-demo-upload"> <img id="LAY_demo_upload" src="layui/images/tong.jpg"> <div class="site-demo-upbar"> <input type="file" name="file" class="layui-upload-file" id="test"> </div> </div><p style="margin-top: 20px">注：由于服务器资源有限，所以此处每次给你返回的是同一张图片</p><script src="layui/layui.js"></script> <script> layui.use('upload', function(){layui.upload({url: '' //上传接口,success: function(res){ //上传成功后的回调 console.log(res) } }) layui.upload({url: '/test/upload.json',elem: '#test' //指定原始元素，默认直接查找class="layui-upload-file",method: 'get' //上传接口的http类型,success: function(res){ LAY_demo_upload.src = res.url } }) }) </script> </body></html>欢迎分享，转载请注明来源：内存溢出
