The more you call their name, the better they feel.
The Problem
Compare the two dialogs below.
- Log 1
- Where are you from?
- I'm from New York.
- Log 2
- Where are you from, Jack?
- I'm from New York.
The dialog 2 is obviously better because the Tutor mentions the name of student but how we could do that?
In the previous session of this tutorial, we captures name from Input with * and returns it through <s/>. Can we store the name and then use it anytime anywhere as we want?
The Solution
You may use <u/> element to store anything you capture with <s/> and then returns it later. Check BrainXML Reference for more information on u element. The below are additional examples demonstrating how you may capture, memorize, and retrieve the students' name.
Example 1. Capturing name
- Cell 1
- My name is *
-
<strong/>what is your name - Nice to meet you,
<s/>!
Example 2. Capturing and memorizing name
- Cell 2
- My name is *
-
<strong/>what is your name - Nice to meet you,
<u>name=<s/></u>!
Alternatively, we may put the <u/> element in <think/>.
- Cell 3
- My name is *
-
<strong/>what is your name - Nice to meet you,
<s/>!
<think>
<u>name=<s/></u>
</think>
Once Cell 2 or 3 is executed, the name is stored in the "name" property of system user object. You can then refer the use with <u>name</u> element.
- Cell 3
- Do you remember my name?
- Sure, you told me you're
<u>name</u>.
- My name is Jack.
- Nice to meet you, Jack!
- ...
- Do you remember my name?.
- Sure, you told me you're Jack.
You can of course use <u> element to store and return any other data such as gender, age or location.
To answer the questions you might have:
- Q: Will names mix up if there are many users?
- A: No, never. BrainShop maintains an object for each user.
- Q: Where and how the user object is stored or retrieved?
- A: BrainShop takes care of that so you don't have to. You can focus yourself on building your own application without worrying about processing the data.
- Q: Is the user object permanent?
- A: Nearly permanent but we would clear the user object if the user is inactive for a very long time, saying a year.
Things to Keep in Mind
- Use
<u/>element to store/return user data such as name, gender, or age.
