代码
(function(window){ window.htmlentities = { /** * Converts a string to its html characters completely. * * @param {String} str String with unescaped HTML characters **/ encode : function(str) { var buf = []; for (var i=str.length-1;i>=0;i--) { buf.unshift(['&#', str[i].charCodeAt(), ';'].join('')); } return buf.join(''); }, /** * Converts an html characterSet into its original character. * * @param {String} str htmlSet entities **/ decode : function(str) { return str.replace(/&#(\d+);/g, function(match, dec) { return String.fromCharCode(dec); }); } };})(window);
测试
console.log(htmlentities.encode('中华人民共和国')) console.log(htmlentities.decode('中华人民共和国'))
输出
中华人民共和国 中华人民共和国
