How can i execute each function with his KeyWord to excute it

Question

const CMDS = [
"Time",
"Date",
"Battery",
"Evaluate Math Simple Expressions(EMSE)",
"Calendar",
"Help"
];
const fun = [
"time()",
"date()",
"battery()",
"EMSE()",
"Calendar()",
"help()"
];
var cmd = cap;
let used = false;
for(let i=0;i<CMDS.length;i++){
if(cmd.toLowerCase()==CMDS[i].toLowerCase()){
used = true;
break;
}
For example:
User_input = "Time";
It should get the keyword time, and it works perfectly, but how I code this to call the time() function and show it to the user

Answer 1

Yes, but the program recognize the keyword as a string not a function. Thats why it doesnt work.
To call them you can use window[keyword]()
Like my first example.

Or look at this one

Answer 2

For web ? Are the functions in the global scope ?
Then use this.
window[user_input]()

Answer 3

Yeah, if those function (time, date, battery, etc) in a global scope. Not inside a class or other function. Then you can use my method above

Answer 4

type "time" inside the form without quotation marks. Then click the button. It'll call the function named time from the code

Answer 5

Taste take a look of the code
$(function() {
// user = prompt("Type your name");
//while (user === null || user === '') {
// user = prompt("Type your name");
//}
$("#btn").on("click", function() {
cap = $("#inp").val();
$("#inp").val("");
if (cap !== "") {
user_input = $('<p class="user-container"></p>').text(cap);
$(".main-container").append(user_input);
const CMDS = [
"Time",
"Date",
"Battery",
"Evaluate Math Simple Expressions(EMSE)",
"Calendar",
"Help"
];
const fun = [
"time()",
"date()",
"battery()",
"EMSE()",
"Calendar()",
"help()"
];
var cmd = cap;
let used = false;
for(let i=0;i<CMDS.length;i++){
if(cmd.toLowerCase()==CMDS[i].toLowerCase()){
used = true;

Answer 6

Taste the idea of this program is to run a function typing a keyword.
Example:
Input: time
Output: 11:50am/pm
The program recognized the keyword time and call the function time.
That's what I want to do, the problem is that it takes the keyword but it doesn't call the function
