how to parse string to int in javascript

How can I get windows.getComputed style as an int value?
The way it is displayed by default is string:
var style = window.getComputedStyle(elem1, null);
alert(style.top); //Returns a string
parseInt() will return you the String as an Integer, so your code should look somehow like this:
var style = window.getComputedStyle(elem1, null);
alert(parseInt(style.top));
parseFloat will give you the real value as a number with decimal places preserved:
parseFloat(style.top);

How to format a number with commas as thousands separators?

Closed 3 years ago.
Is there a way to use the below JavaScript code to use comma's? For example the var num = 1924.00 Is there way to get it to display as 1,924.00?
var num = parseFloat(totalAmount).toFixed(2);
You could use a specific regex like this one in the function below:
function format_currency( value ) {
return value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
If you want to use it in conjuction with the .toFixed(), just do like this:
format_currency( 1245.3.toFixed(2) );
Hope it helps.

So im quite new to javascript and i tried making something simple as entering a value and add 150 to it but it wont show number + 150?

That's because you are concatenating strings. You need to convert the strings to integers by using parseInt(), and then add the numbers.
https://www.w3schools.com/jsref/jsref_parseint.asp
var fullprice = parseInt(price) + 150;
Because you're actually concatenating a string with a number. The input value is a string, so before operating with it, parse it to int with parseInt

How could I transform a number with commas like 123,245 to a number without commas like this 123245, I know that you could already put commas in number without them but how to do that in reverse?
pure JAVASCRIPT please!
var number = Number("123,456".split(",").join(""));
Or:
var number = parseInt("123,456".split(",").join(""));
An alternative is using a regex /,/g
console.log("123,245".replace(/,/g, ''));
console.log("123,245,566".replace(/,/g, ''));
