js 遞歸遍歷修改對象

function processCharacter( obj ) { 
    for( var i in obj ) { 
          if ( typeof obj[i] === 'object' ) { 
               processCharacter ( obj[i] ); 
          }else{ 
                 if(typeof (obj[i])==='string')
                     obj[i]=encodeURIComponent(obj[i])
                 }
          } 
} 


var param = {"name":"zhangsan+2%-=@", "list1": [4, 5, 6] };
processCharacter(param);
console.log(param);

遞歸修改json對象中string類型的值，進行encodeURIComponent編碼
