angularJS+Ionic实现移动端图片上传功能

$scope.imgList = [];
$scope.setUploader = function () {
 var files = document.getElementById('photo');
 files.click();
 $(files).unbind().on('change',function (e) {
 var file = e.target.value;
 if (!/.(jpg|jpeg|png|GIF|JPG|png)$/.test(file)) {
 common.toast('图片类型必须是jpeg,jpg,png中的一种');
 return false;
 };
 fsubmit();
 readAsBinaryString();
 });
};

function fsubmit() {
 var itemImg = {};
 var form=document.getElementById("form1");
 console.log('form',form)
 var formData=new FormData(form);
 formData.append('wxdesigner_sid',$.fn.cookie('wxdesigner_sid'));
 formData.append('id',$scope.masterInfo.id);
 formData.append('pc','1');
 var oReq = new XMLHttpRequest();
 oReq.onreadystatechange=function(){
 if(oReq.readyState==4){
 if(oReq.status==200){
 var json=JSON.parse(oReq.responseText);
 console.log(json)
 if(json.Success) {
 itemImg = json.Data;
 $scope.imgList=itemImg;
 console.log($scope.imgList)
 $scope.$apply();
 itemImg = {};
 }
 }
 }
 };
 console.log(oReq)
 console.log(formData)
 oReq.open("POST", common.api+"Wxdesigner/Designer/uploadworks");
 oReq.send(formData);
 return false;
};
//判断浏览器是否支持FileReader接口
if(typeof FileReader == 'undefined'){
 //使选择控件不可操作
 file.setAttribute("disabled","disabled");
}

function readAsBinaryString(){
 var file = document.getElementById('photo').files[0];
 console.log(file)
 var reader = new FileReader();
 //将文件以二进制形式读入页面
 reader.readAsDataURL(file);
 reader.onload=function(f){
 $scope.masterInfo.thumblist.push(f.currentTarget.result)
 console.log($scope.masterInfo)
 $scope.$apply()
 }
}
