JSON字符串操作移除空串更改key/value的介绍

//删除JSON对象value值var json=[.....];delete(json['key']);或者delete(json.key);//添加对象objectjson.object=value;或者json['object']=value;

 function removeEmptyObject(object){   for (var i in object) {  var value = object[i];  if (typeof value === 'object') {   if (Array.isArray(value)) {    if (value.length == 0) {     delete object[i];     continue;    }   }   removeEmptyObject(value);   //按需添加   if (isEmpty(value)) {    delete object[i];   }  } else {   if (value === '' || value === null || value === undefined) {    delete object[i];   } else {   }  } } return object;}//是否为空function isEmpty(object) { for (var name in object) {  return false; } return true;}

 function removeEmptyObject(object){   for (var i in object) {    var value = object[i];    if (typeof value === 'object') {     if (Array.isArray(value)) {      if (value.length == 0) {        //alert(object[i]);       delete object[i];       continue;      }else{         var a=[];        if(i=='jobChildren'){          for (var j = 0; j < object[i].length; j++) {            a.push(object[i][j]);          }          delete object[i];        }else if(i=='userChildren'){          for (var j = 0; j < object[i].length; j++) {            a.push(object[i][j]);          }          delete object[i];         }else if(i=='deptChildren'){          for (var j = 0; j < object[i].length; j++) {            a.push(object[i][j]);          }          delete object[i];         }else if(i=='companyChildren'){          for (var j = 0; j < object[i].length; j++) {            a.push(object[i][j]);          }          delete object[i];         }else if(i=='jobDeptChildren'){          for (var j = 0; j < object[i].length; j++) {            a.push(object[i][j]);          }          delete object[i];        }        if(a.length>0&&object["children"]!=undefined){          for (var k = 0; k < object["children"].length; k++) {            a.push(object["children"][k]);          }          object["children"]=a;        }else if(a.length>0 && object["children"]==undefined){          object["children"]=a;        }       }     }     removeEmptyObject(value);     if (isEmpty(value)) {      delete object[i];     }    } else {     if (value === '' || value === null || value === undefined) {      delete object[i];     } else {     }    }   }  }  function isEmpty(object) {   for (var name in object) {    return false;   }   return true;  }
