Beispiel einer Funktion zum Hochladen mehrerer Bilder, die vom Laravel-Framework + Blob implementiert wird

<form method="post" enctype="multipart/form-data" action="#">
  {{csrf_field()}}
  <ul class="list_btn">
  <li><img id="imgone" class="sz" width="100px" height="100px" src="" style="display: none;"></li>
   <li> <input type="file" id="house_img_one1" name="art_thumb" multiple="multiple" onchange="houseImgOne(this)"></li>
</ul>
  <p class="submit">上传</p>
</form>

    _btnId = $(_this).attr(&#39;id&#39;);
    var obj = document.getElementById("house_img_one1");

    //多图上传时遍历文件信息（可以通过object.files查看）
    for (var i = 0; i < length; i++) {

      //图片后缀类型拼接
