How to remove a char from a string, and return a number from the new string - Javascript -

I have some functions that change a user input as a binary number in the form of a string. This is part of a basic 'assembler' program on which I am working. Here is my code:

  Function GenerNinBurnerNumber (InputWall) // only works for hash! {Var number; If (hash (input value) in it! = -1) {number = getNumberFromString (inputValue); } Return Decimal Tokyo (number); } Function hash (number) // functioning! {Var n = number.indexOf ('#'); Return n; } Function getNumberFromString (mixed input) // work! {Return (mixed input. Location ('#', '')); } Function Decimal Tutorial (Decimal) // Working! {Decimal = parsih (decimal); Return decimal Two string (2); } For example, if a user enters the value of '5', then the function returns NaN - although if they specify that # 5 works - 101 returns. I'm new to programming and javascript, if someone could point me in the right direction which would be great. Thanks!  
 
 
 
 if any  #   
  function Generate BinaryNumber (inputValue) // only works for hash! {Var number; // if the number is not set (hash (input value) in it! = -1) {// the number is set here, but only if if statement is true number = getNumberFromString (inputValue); } // If, then hash was false, the number is undefined decimal decimal number (number); }   
 You only want to say  var number = inputValue  when you declare it  
 As a side note, Your paraset does not look like a radius argument (something like  parseInt (decimal, 10) ) otherwise it will input as hex digits such as  "010"  and it will Will parse incorrectly.
