var adds = {};
Page({
  data: {
    img_arr: [],
    formdata: '',
  },
  formSubmit: function (e) {
    var id = e.target.id
    adds = e.detail.value;
    adds.nowTime =new Date().getTime();
    this.upload()
  },

  upload: function () {
    var that = this
    for (var i = 0; i < this.data.img_arr.length; i++) {
      adds.index = i;
      console.log(adds)
      wx.uploadFile({
        url: 'http://localhost/upImg/up_img.php',
        filePath: that.data.img_arr[i],
        name: 'file',
        formData: adds,
        success: function (res) {
          console.log('1111111111',res)
          if (res) {

            });
          }
        }
      })
