上篇文章「JavaScript检测原始值、引用值、属性」中涉及了大量有用的代码范例,为了让大家更方便的使用这些代码,博主特意把这些代码重新整理并托管到 GitHub,项目地址是:https://github.com/stone0090/s-fontend/tree/master/me/basevalidate

basevalidate.js 包含 14个独立检测方法1个综合检测方法,示例代码如下:

var nums = [123, 456, 789];
// 14个独立检测方法
console.log(baseValidate.isString(null));
console.log(baseValidate.isNumber(null));
console.log(baseValidate.isBoolean(null));
console.log(baseValidate.isUndefined(null));
console.log(baseValidate.isNull(null));

console.log(baseValidate.isFunction(null));
console.log(baseValidate.isArray(null));
console.log(baseValidate.isProperty(null));
console.log(baseValidate.isOwnProperty(null));
console.log(baseValidate.isDomProperty(null));
console.log(baseValidate.isBomProperty(null));
console.log(baseValidate.isEmpty(null));
// 1个综合检测方法 baseValidate(value, object),等价于 baseValidate.validateAll(value ,object)
console.log(baseValidate('123'));
console.log(baseValidate(123));
console.log(baseValidate(true));
console.log(baseValidate(person, Person));
console.log(baseValidate(nums));
console.log(baseValidate('age', person));
console.log(baseValidate('name', person));
console.log(baseValidate(alert));
console.log(baseValidate(document.getElementById));
// 以下皆为 isEmpty() 方法为 false 的情况
console.log(baseValidate()); // 不传参数,参数默认为 undefined
console.log(baseValidate(null));
console.log(baseValidate(''));
console.log(baseValidate(0));
console.log(baseValidate(false));
console.log(baseValidate({}));
console.log(baseValidate([]));
console.log(baseValidate(NaN));
</script>
</head>
<body></body>
</html>

测试结果如下:

不知道大家有没有发现,其中一个结果好像不太正确,console.log(baseValidate('name', person)) 为什么会输出 isBomProperty: true,这是因为window 对象中也有 name 属性,所以 name 也被认为是 BOM 的属性。
