Issue
I am adding two numbers, but I don't get a correct value.
For example, doing 1 + 2
returns 12
and not 3
What am I doing wrong in this code?
function myFunction() {
var y = document.getElementById("txt1").value;
var z = document.getElementById("txt2").value;
var x = y + z;
document.getElementById("demo").innerHTML = x;
}
<p>
Click the button to calculate x.
<button onclick="myFunction()">Try it</button>
</p>
<p>
Enter first number:
<input type="text" id="txt1" name="text1" value="1">
Enter second number:
<input type="text" id="txt2" name="text2" value="2">
</p>
<p id="demo"></p>
Solution
They are actually strings, not numbers. The easiest way to produce a number from a string is to prepend it with +
:
var x = +y + +z;
