Fill in the blank using jQuery

Fill in the blank using jQuery

Hi there,

I'm new to jQuery and looking for existing plugins to get an idea for my primary school class (i'm a teacher) working.
I want to make a fill in the blank exercise for my students but don't know how to get started.

When the student clicks on "controleren", I want jQuery to check the value of the field and compare it with the correct answer.
Can someone help me and point me to a working example or a plugin that has the features I need?

Thanks!
