基于alibaba-designable源码二次封装的表单设计器。

const isType = type => obj => obj != null && (Array.isArray(type) ? type : [type]).some(t => getType(obj) === `[object ${t}]`);
export const getType = obj => Object.prototype.toString.call(obj);
export const isFn = isType(['Function', 'AsyncFunction', 'GeneratorFunction']);
export const isWindow = isType('Window');
export const isHTMLElement = obj => {
  return obj?.['nodeName'] || obj?.['tagName'];
};
export const isArr = Array.isArray;
export const isPlainObj = isType('Object');
export const isStr = isType('String');
export const isBool = isType('Boolean');
export const isNum = isType('Number');
export const isObj = val => typeof val === 'object';
export const isRegExp = isType('RegExp');
export const isValid = val => val !== null && val !== undefined;
export const isValidNumber = val => !isNaN(val) && isNum(val);
