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>
