                            ## 正則驗證，match()與test()函數的區別？
test是RegExp的方法，參數是字符串，返回值是boolean類型。

~~~
var str='sad13123dfa4v564d5f8fb5sf'; 

var re=/\d+/g; 

alert(re.test(str));
~~~

match是String的方法，參數是正則表達式，返回值是數組。

~~~
var re=/\d+/g; 

alert(str.match(re)); 
~~~

~~~
var str = 'haj123sdk54hask33dkhalsd879';
var re = /\d+/g; // \d代表數字，\d+代表至少一個。g代表全局
console.log(str.match(re)); //123,54,33,879
