url参数里有文字，获取为乱码解决办法

function getUrlV() {
     var vars = [], hash;
     var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
     for (var i = 0; i < hashes.length; i++) {
          hash = hashes[i].split('=');
          vars.push(hash[0]);
          vars[hash[0]] = hash[1];
     }
     return vars;
 } 

　　

var params = getUrlV();
decodeURI(params.参数名)
