利用laravel+ajax实现文件上传功能方法示例

@extends('layouts.art')@section('content')<form class="form-horizontal" id="avatar">    {{ csrf_field() }} <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">名字</label> <div class="col-sm-8">  <input type="title" class="form-control" id="title" name="title"> </div> </div> <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">头像</label> <div class="col-sm-8">  <input type="file" class="form-control" id="title" name="photo"> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10">  <a class="btn btn-default" onclick="uploadInfo()">上传</a> </div> </div></form><script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script> <script type="text/javascript"> function uploadInfo() {   var formData = new FormData($("#avatar"));   $.ajax({    url: "{{url('photo')}}",   type: 'POST',    data: formData,    contentType: false,    processData: false,    success: function (returndata) {     console.log(returndata);    },    error: function (returndata) {     console.log(returndata);    }   }); } </script>@endsection
