In the previous lesson, we created a Person Class. So if we want to define the same class in backbone js. And that’s what we will be learning in this lesson. “Defining models in Backbone js.” It’s pretty straight forward. Remove the previous code from
main.js and add this code. Take a look on this.
In the above code, we are defining the class and set some default values like for name, age, and occupation.
Now if checkout chrome we can see a lot of cool awesome things. Type these commands one by one.
We can get all the previous things like to get the name, age or occupation. In backbone js, we do that by using get method
You can’t do things like:
And now you can even update name, or age, etc.
or you can update the values in just on go ie
Another thing can be you can set values while launching, i.e.,
Let’s take a look how things look like on chrome console.
That’s how you define models in Backbone js. In the next post, let’s add some validations in the model. For example. Age can’t be zero or negative. Or name can’t be blank etc.
If you are facing any issues. Check out the source code files at github. I will be creating more and more directories in the same repo regarding each post. Still, if you have any doubts you can comment on the blog post itself, and I will try to reply back asap.
