H5开发时使用Ajax上传Base格式图片

 <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>

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]);
 }
 }
}

//单张图片上传
var inputs = $("input.fileupload");
for (var i = 0; i < inputs.length; i++) {
 //图片转base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: 'POST',
 url: 'http://10.145.0.05/goods/addGoodsBase',
 dataType: "json",
 data: {
 "base": event.result,
 },
 success: function(data) {
 console.log(data);
 }
 });
 }
 }
}
