Main attributes of the form:

Note:

The modal component used in this case is about to expire. It is recommended to use wx.showModal API

to rewrite the formSubmit method like this. Currently, the content of the wx.showModal API does not support line breaks. It may be a bug. We look forward to subsequent optimization.

formSubmit: function(e) {
    var value =  e.detail.value;
    wx.showModal({
      title: '您填写的表单如下',
      content: '姓名:'+value.name
              +'性别：'+value.gender
              +'年龄：'+value.age
              +'擅长的开发语言：'+value.technology
              +'是否公开信息：' + value.isPublic,
      showCancel: false,
      success: function(res) {
        if (res.confirm) {
          console.log('用户点击确定')
        }
      }
    });
  },
