I am trying to convert a phone number on a web page into an integer value but it repeatedly returns NaN, despite being a number. This is part of a chrome extension. My code is as follows:
currNum = String(document.getElementsByClassName("number")[0].innerHTML).trim()
console.log("First: " + currNum)
currNum = currNum.replace("(","").replace(")","").replace("-","").replace(" ","")
console.log("Second: " + currNum)
currNum = parseInt(currNum)
console.log("Third: " + currNum)
The logged output is:
First: (206) 000-0000
Second: 2060000000
Third: NaN
Is there something about this number that can't be cast to an int?
Thanks
Use a regex (ie /[()\s-]/g)✥ as the first param of .replace() and instead of " " for a space, use \s which will match all types of whitespace (including the 202A, Pointy mentioned). Also, replace .innerHTML with .textContent.
✥Note: /[()\s-]/g will match each (, ), -, and whitespace. Place the - at the end of expression or it could be misinterpreted as a range.
let currNum = String(document.querySelector(".number").textContent).trim()
console.log("First: " + currNum)
currNum = currNum.replace(/[()\s-]/g,"");
console.log("Second: " + currNum)
currNum = parseInt(currNum)
console.log("Third: " + currNum)<address>
<p class='number'>(206) 555-0000</p>
</address>currNum = currNum.replace(/[\s()-]/g, '')
