vue判断变量类型

const typeOf = data => {
let type = Object.prototype.toString.call(data);
if (type === “[object String]”) {
type = “String”;
} else if (type === “[object Number]”) {
type = “Number”;
} else if (type === “[object Null]”) {
type = “Null”;
} else if (type === “[object Boolean]”) {
type = “Boolean”;
} else if (type === “[object Array]”) {
type = “Array”;
} else if (type === “[object Object]”) {
type = “Object”;
} else {
type = “未进行判断的类型:” + type;
}
return type;
};
