// Replaces all instances of the given substring.
String.prototype.replaceAll = function(strTarget, strSubString)
{
  var strText = this;
  var intIndexOfMatch = strText.indexOf( strTarget );
   
  // Keep looping while an instance of the target string
  // still exists in the string.
  while (intIndexOfMatch != -1){
    // Relace out the current instance.
    strText = strText.replace( strTarget, strSubString )
    
    // Get the index of any next matching substring.
    intIndexOfMatch = strText.indexOf( strTarget );
  }
   
  // Return the updated string with ALL the target strings
  // replaced out with the new substring.
  return( strText );
