Last modified on

This small JavaScript prototypes enhance the trim() function and allow for better trimming and/or replacing line breaks with commas (or any other character).


 * Prototype function to remove all double whitespaces and preceding line breaks
String.prototype.allTrim = String.prototype.allTrim || function() {
    return this
            .replace(/  +/g, ' ')
            .replace(/\n\s*\n/g, '\n')
            .replace(/(\r\n|\n|\r)/gm, '') // Remove all 3 types of line breaks
            .replace(/^,+/, '')
            .replace(', ,', ',')

 * Prototype function to replace all line breaks with commas
String.prototype.allCommas = String.prototype.allCommas || function() {
    return this
            .replace(/(\r\n|\n|\r)/gm, ', ')
