Front-end Web Development

Assignment for Week 9

Create an HTML file. (Start with the HTML file in Assignment 1 as a basis. Feel free to skip the CSS creation/linking steps.)
Create a JS file (a blank file with a .js extension).
Add a <script> tag to the end of the <body> in the HTML file. Set its src attribute to the name of your JS file.
In the JS file, declare a variable called createName and assign it a function:
1. The function should accept two arguments, first and last.
2. It should return a string which concatenates first, a space, and last.
Declare another variable called askName and assign it another function:
1. In the function, declare a variable called first, and assign it the result of the prompt DOM function call, which should ask for your first name.
2. Declare a variable called last, and assign it the result of another prompt call, which should ask for your last name.
3. Declare a variable called fullName, and assign it the result of calling the createName function we created above, passing in the first and last variables.
4. Call the alert DOM function, using the fullName variable to tell the user what their full name is, e.g. Your name is John Smith!.
5. No return command necessary.
Call the askName function.

In the HTML file, add an id attribute to the <p> tag, and set it to "asker".
Add a line to the JS file that passes in that id value as a parameter of the document.getElementById function call, then sets its result's onclick property to the askName variable.
If all goes well, clicking on the paragraph on your page should pop up first/last name prompts.

Modify askName to keep asking for your name until your full name is Murray Stenson.
