某字段沒有值的時候 后端要求直接干掉此字段探遵，估寫了個方法對數(shù)據(jù)進行處理

//過濾請求參數(shù)中的空字符串,null,undefined和空對象
const searchData = {
    job: 'teacher',
    name: '',
    age: null,
    sex: undefined,
    hobby: [],
    under_take_count: {
        target_type: 0,
        target_count_from: '',
        target_count_end: '',
    },
    under_take: {
        target_count_from: '',
        target_count_end: '',
    },
};
function handleData(data) {
    const keys = Object.keys(data);
    if (keys.length > 0) {
        keys.forEach(currentKey => {
            const currentVal = data[currentKey];
            //處理值為對象的結構
            if (!Array.isArray(currentVal) && (currentVal instanceof Object) && Object.keys(currentVal).length > 0) {
                const objeVal = handleData(currentVal);
                if (Object.keys(objeVal).length > 0) {
                    data[currentKey] = objeVal;
                } else {
                    //刪除空對象
                    delete data[currentKey];
                }
            } else {
                if (['', null, undefined].includes(currentVal)) {
                    delete data[currentKey]
                }
            }
        })
    }
    return data;

console.log(handleData(searchData));
