一些数据在PHP里用urledcode了，传到前端，需要把数据转换，不然有些特殊的字符会以%开始的转换字符，JS decodeURIComponent 函数可以转换。

function urldecode (str) {    // Decodes URL-encoded string      //     // version: 1109.2015    // discuss at: http://phpjs.org/functions/urldecode    // +   original by: Philip Peterson    // +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)    // +      input by: AJ    // +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)    // +   improved by: Brett Zamir (http://brett-zamir.me)    // +      input by: travc    // +      input by: Brett Zamir (http://brett-zamir.me)    // +   bugfixed by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)    // +   improved by: Lars Fischer    // +      input by: Ratheous    // +   improved by: Orlando    // +      reimplemented by: Brett Zamir (http://brett-zamir.me)    // +      bugfixed by: Rob    // +      input by: e-mike    // +   improved by: Brett Zamir (http://brett-zamir.me)    // %        note 1: info on what encoding functions to use from: http://xkr.us/articles/javascript/encode-compare/    // %        note 2: Please be aware that this function expects to decode from UTF-8 encoded strings, as found on    // %        note 2: pages served as UTF-8    // *     example 1: urldecode('Kevin+van+Zonneveld%21');    // *     returns 1: 'Kevin van Zonneveld!'    // *     example 2: urldecode('http%3A%2F%2Fkevin.vanzonneveld.net%2F');    // *     returns 2: 'http://kevin.vanzonneveld.net/'    // *     example 3: urldecode('http%3A%2F%2Fwww.google.nl%2Fsearch%3Fq%3Dphp.js%26ie%3Dutf-8%26oe%3Dutf-8%26aq%3Dt%26rls%3Dcom.ubuntu%3Aen-US%3Aunofficial%26client%3Dfirefox-a');    // *     returns 3: 'http://www.google.nl/search?q=php.js&ie=utf-8&oe=utf-8&aq=t&rls=com.ubuntu:en-US:unofficial&client=firefox-a'    return decodeURIComponent((str + '').replace(/\+/g, '%20'));    }
