Javascript add +1 to string
21,165
Under the assumption that you are absolutely sure that the number is a decimal integer. Either
text = +text + 1;
Or
text = parseInt(text, 10) + 1;
Or
text = Number(text) + 1;

I have a variable that stores a innerHTML text in it
var text = document.getElementById("textID").innerHTML; // <-- textID is actually a number
The "text" is actually just a number but I guess javascript still thinks it's a string.
I want to add + 1 to the variable text, but it just adds a new letter instead of increasing the number
For example : 0 + 1 = 01 --> 01 + 1 = 011 and so on...
Here's the code I tried this with:
text = text + 1;
How can I make it so it increases the number instead of adding new letters? (1+1 = 2, etc)
