vue全局设置传值到后台不能为null

export const notNull = (data) => {
for (let k1 in data) {
if (data[k1] === null) {
data[k1] = ‘’;
continue;
}
if (Object.prototype.toString.call(data[k1]) === ‘[object Object]’) {
notNull(data[k1]);
continue;
}
if (Array.isArray(data[k1])) {
for (let k2 in data[k1]) {
if (
Object.prototype.toString.call(data[k1][k2]) === ‘[object Object]’
) {
notNull(data[k1][k2]);
}
}
continue;
}
}
return Object.assign({}, data);
};
