var str2 = "悬剑18686868866陕西省西安市雁塔区大雁塔街道广场";

  changtext: function(e) {
    var that = this,
      text = e.detail.value,
      text = text.replace(/(^\s*)|(\s*$)/g, "");
    var regx = /(1[3|4|5|7|8][\d]{9}|0[\d]{2,3}-[\d]{7,8}|400[-]?[\d]{3}[-]?[\d]{4})/g;
    var phoneNums = text.match(regx);
    if (phoneNums.length != null) {
      var phone = text.indexOf(phoneNums[0]);
    }
    var name = text.indexOf("姓名:");
    if (name >= 0) {
      var phone = text.indexOf("电话:"),
        address = text.indexOf("地址:");

      var u_name = text.substring(name + 3, phone),
        u_phone = text.substring(phone + 3, address),
        u_address = text.substring(address + 3, text.length);

      that.setData({
        u_name: u_name,
        u_phone: u_phone,
        u_address: u_address
      })
    } else if (phone >= 0) {
      var u_name = text.substring(0, phone),
        u_phone = text.substring(phone, phone + 11),
        u_address = text.substring(phone + 11, text.length);
      that.setData({
