split()字串分割成字串陣列
var str="How are you doing today?"
document.write(str.split(" ") + "<br />")
document.write(str.split("") + "<br />")
document.write(str.split(" ",3))
reverse()方法用於顛倒陣列中元素的順序
var arr=['how','are','you'];
document.write(arr.reverse())
輸出:
you,are,how
join()把陣列中的所有元素放入一個字串
var arr=['how','are','you'];
document.write(arr.join()+'<br/>')
document.write(arr.join(''))
輸出:
how,are,you
howareyou
