This article mainly introduces H5 mobile development Ajax to upload multiple Base64 format pictures to the server in detail. It has a certain reference value. Interested friends can refer to it

No more nonsense , just look at the code

1. Upload components

 <p class="imgbox">
   <img class="goodsimg" src="../../assets/addimg.png">
   <input id="file" type="file" class="fileupload" accept="image/*" multiple capture="camera" @change="viewimg()"/>
 </p>

2. Display and add The picture on

viewimg($event) {
   //获取当前的input标签
   var currentObj = event.currentTarget; 
   //找到要预览的图片img标签，亦可动态生成
   var img = currentObj.parentNode.children[0]; 
   setImagePreview(currentObj, img);

   function setImagePreview(docObj, imgObjPreview) {
     if (docObj.files && docObj.files[0]) {
        imgObjPreview.style.display = 'block';
        imgObjPreview.src = window.URL.createObjectURL(docObj.files[0]);
    }
  }
}

3. Get the picture and upload it to the server

//单张图片上传
var inputs = $("input.fileupload");
for (var i = 0; i < inputs.length; i++) {
  //图片转base64上传
  var file = inputs[i].files;
  if (file[0]) {
    var reader = new FileReader();
    reader.readAsDataURL(file[0]);
    reader.onload = function(e) {
   var event = this;
   console.log(event.result);
      $.ajax({
        type: &#39;POST&#39;,
        url: &#39;http://10.145.0.05/goods/addGoodsBase64&#39;,
        dataType: "json",
        data: {
          "base64": event.result,
        },
        success: function(data) {
          console.log(data);
        }
      });
    }
  }
}
