I'm adding two numbers but I'm not getting the correct value.
For example, executing 1 2
returns 12 instead of 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>
I just use
Number()
:They are actually strings, not numbers. The easiest way to generate a number from a string is to prepend it with
:
