JavaScript exercises and solutions - Swap two numbers - Qomplainerz - 04-04-2023

The HTML part between the <body></body> tags looks like this:

Code:
Enter the first number here: 

<br>

<input type="Text" id="Num1">

<br>

Enter the second number here:

<br>

<input type="Text" id="Num2">

<br>

<input type="button" id="submit" value="submit" onclick="SwapNumbers()"></input>

<p id="Output"></p>

<input type="button" id="reset" value="Reset" onclick="Reset()"></input>

The JavaScript part looks like this:

Code:
function SwapNumbers()

{

  Num1 = document.getElementById("Num1").value;

  Num2 = document.getElementById("Num2").value;

  Num3 = Num1;

  Num4 = Num2;

  Output = "You have entered " + Num4 + " and " + Num3;

  document.getElementById("Output").innerHTML = Output;

}

function Reset()

{

  document.getElementById("Num1").value = "";

  document.getElementById("Num2").value = "";

  document.getElementById("Output").innerHTML = "";

}

Note: The reset button and the reset function are optional in case you want to delete what you were looking for in order to look for something else.
