[JavaScript] Parse Accept-Language in HTTP Request Header
January 22, 2016
This post is the JavaScript version of my previous posts [1] and [3]. This JavaScript example parses Accept-Language string in HTTP Request Header and output (languageTag, quality) pairs:
/**
* Parse HTTP accept-language header of the user browser.
*
* @param {string} hdr The string of accpet-language header
* @return {Array} Array of language-quality pairs
*/
function getParsedAcceptLangs(hdr) {
var pairs = hdr.split(',');
var result = [];
for (var i=0; i < pairs.length; i++) {
var pair = pairs[i].split(';');
if (pair.length == 1) result.push( [pair[0], '1'] );
else result.push( [pair[0], pair[1].split('=')[1] ] );
}
return result;
}
