kissy gallery系列之pinyin

 

   本文收录kissy gallery之pinyin：

 

   主要分解一下其中比较核心的设计思想~

 

     为数不多不依赖底层库的，http://gallery.kissyui.com/pinyin/1.0/guide/index.html?spm=0.0.0.0.i7apRd

 

     不过还是有一些bad case，比如fu系列，以反馈到官方git上

 

   pinyin  

 

   ------- 主要是做汉字转换拼音

    核心的pinyinFn方法：

 

  

function pinyinFn(w){
     //多个汉字的情况
     if(w.length >1){
           var ret = '',
                 i = 0;
           for(;i<w.length;i++){
                 ret += pinyinFn(w.charAt(i));
           }

           return ret;
     }

     //判定是否是中文汉字
     if(!/[\u4e00-\u9fa5]/.test(w)){
           return w;
     }

     //缓存里面 
     if(cache[w]){
           return cache[w];
     }

     var begin = 0,
           end = keyLen;

     //二分法
     while(begin <= end){
           var middle = Math.floor((begin+end)/2);
           if(w.localeCompare(key[middle]) <0){
                 end = middle-1;
           }else{
                 begin = middle+1; 
           }
     }

     return cache[w] = pinyin[end];

}
