javascript - Creating Command Interface Styled HTML Site
Get the solution ↓↓↓
I have been working on building a website with some base functionality that I would be able to add on to later if needed.
I would like users to be able to enter text into the "Type here..." input box and when they press enter it add a new line on their site based on the command they just typed.
For example if they entered "help" it would pint a few new lines explaining what the site does and some beginning commands. My idea is to continue to add commands to there would need to be some scalability to this. I have the website + input box working how I want it to.

Solution:
You need to use Javascript to make it work: You need to use appendChild js command to make it work (https://www.w3schools.com/jsref/met_node_appendchild.asp)
[EDIT]
To resume what is said on the link, you should use the appendChild javaScript property that would allow you to add text on your page from the javascript code:
function getCommand(input){
if (input == "help"){
let p = document.createElement("p"); //creates a new <p> element
let text = document.createTextNode("Text you want to show");
p.appendChild(text); // adds the text to the paragraph
document.body.appendChild(p); // adds <p> to the body of your page
}
else {
let p = document.createElement("p"); //creates a new <p> element
let errorText = document.createTextNode("Invalid Command.");
p.appendChild(errorText); // adds errorText to the <p> element
document.body.appendChild(p);
}
}
Hope I helped you with my answer,
Romain.
