/normalize analytic strings
Created May 7, 2013
quick normalize functions for grooming strings passed into an analytics library like SiteCatalyst
| // this would be set in a closure | |
| // but leave some values to be cached (ie not created every function call) | |
| // and the ability to override | |
| var norm_regex = /\s+/g; | |
| var norm_replace = "_"; | |
| function normalize( val, reg_pattern, separator ) { | |
| // convert to string | |
| var norm_val = val+""; | |
| norm_regex = reg_pattern || norm_regex; | |
| norm_replace = separator || norm_replace; | |
| // analytics is expecting spaces to be "_", case to be lower, and no empty spaces before and after the string | |
| return ""+val.trim().replace(norm_regex, norm_replace).toLowerCase(); | |
| } | |
| // assumptions | |
| // Trim is available in the browser | |
| // https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/Trim | |
| // implement our own or borrow a library's (eg jQuery) |
