Removing Extra Spaces from Strings in Microsoft Jscript

MS Jscript has a ton of functions and methods borrowed from VisualBasic and Microsoft C/C++. Among them is the trim function, which lets you strip extra space characters from the start and end of a string. But what do you do if there are extra spaces between words inside the string?

Here’s a function for you to use as you see fit. The basic idea: split the string and dump it into an array. Then walk through the array elements and build a new string, skipping any array elements that are just spaces. That string gets returned as the result.

We’ll use the split function to create the array.

function TrimInner(Str)
{
  var WordArray = Str.split(/ +/);
  Str = "";

  for (i = 0; i < WordArray.length; i++) {
  	if (WordArray[i] != ' '){
  		Str += (WordArray[i]+ " ")
  	}
  };
  return Str;
}

Pass it the string you need as an argument, and you get back a string with no extra spaces.

This function removes all spaces

function TrimInner(Str)
{
  var WordArray = Str.split(/ +/);
  Str = "";

  for (i = 0; i < WordArray.length; i++) {
  	if (WordArray[i] != ' '){
			    		Str += (WordArray[i])
  	}
  };

  return Str;
}
