JavaScript view newlines & tabs in string

Content

View a string's newlines and tabs in JavaScript. This function replaces line endings/newlines and tabs:

function raw(str) {     return str.replace(/\t/g, '\\t')              .replace(/\r\n/g, '\\r\\n')              .replace(/\r/g, '\\r')              .replace(/\n/g, '\\n'); }

The /g modifier finds and replaces all occurrences.
