Parsing Numbers From Strings Challenge 1 of 2

Any clues to the answer to this challenge. I've tried every variation I can think of. No mention in the forum for this. Little Help...

A variable named "boxWidth" already exists with a value of "640px". Create a new variable named "numWidth" and use the "parseInt" method to extract the numeric value from boxWidth's string value.

 var boxWidth = "640px";
  var boxHeight = "480px";
  var numWidth =  parseInt("640", 10);

You are supposed to extract the number from the boxWidth's variable not from a string literal. So swap out the number you are using for the variable name boxWidth.

You beat me!

Thank you James and Chris ! Much appreciated.

Hi Michael,

That code challenge wants you to parse the number out of the boxWidth variable. You are trying to parse it from a string literal "640". So the answer would be in the form:

var targetVariable = parseInt(sourceVariable, radix);
