$(function () {        var shanxiArr = [];         $.ajax({             url: 'city.php',             type: 'get',             dataType: 'json',         })         .done(function(data) {             $.each(data, function(i, province) {              var provinceName = i.substring(0,2);              var province_pinyin = ConvertPinyin(provinceName);                   if ("shanxi" == province_pinyin) {                   shanxiArr.push(province_pinyin);                   console.log(shanxiArr);                 }                // console.log(province_pinyin);               var h3Item = "<li  class='fl'> <a href='http://www.reading-china.com/"+province_pinyin+"' target='_blank' rel='external nofollow'>"+province_name+"</a> </li>";               $('#cheng_shi').append(h3Item);             });         })         .fail(function() {             console.log("error");         });     })我想取出shanxi添加到數組，然后把數組[1]==shanxixi，可是我遍歷出來的怎么是循環了兩遍？我怎么把陜西的拼音改成shanxixi  ？
