推荐答案

scope.InsertR ecord = function （）{
var filedata;
var f = document .getElementById（' file'）。files [ 0 ]，r = new FileReader（）;
alert（f.length）;
r.onloadend = function （e）{
filedata = e.target.result;
// console.log（filedata.length）

scope.InsertRecord = function () { var filedata; var f = document.getElementById('file').files[0], r = new FileReader(); alert(f.length); r.onloadend = function (e) { filedata = e.target.result; //console.log(filedata.length)

.ajax（{
type： POST，
url ： service.asmx / insertMethod，
data： {'title'：' +

.ajax({ type: "POST", url: "service.asmx/insertMethod", data: "{'title':'" +

scope.news_title + '，'desc'：' +

scope.news_title + "','desc':'" +
