js中汉字utf8编码互相转换

//UTF字符转换var UTFTranslate = {Change:function(pValue){return pValue.replace(/[^\u0000-\u00FF]/g,function($0){return escape($0).replace(/(%u)(\w{4})/gi,"&#x$2;")});},ReChange:function(pValue){return unescape(pValue.replace(/&#x/g,‘%u‘).replace(/\\u/g,‘%u‘).replace(/;/g,‘‘));}};例如：UTFTranslate.ReChange(‘中文sdfdf‘); //"中文sdfdf"UTFTranslate.Change(‘中文sdfsf‘); // "中文sdfsf"//Asc转换var AscTranslate = {Change: function(pAscString, pBoxId){/* 转ASCII */box = document.getElementById(pBoxId);box.innerHTML = ‘‘;for(i = 0; i < pAscString.length; i++){var asc = pAscString.charCodeAt(i);var str = String.fromCharCode(asc);box.innerHTML += str + ‘:‘ + asc + ‘<br/>‘;}}}
