复制代码代码如下:

function getElementsbycasname (n) {

var classeLements = [], allelements = document.geteLementsbyTagname ('*');

untuk (var i = 0; i <allelements.length; i ++)

{

if (allelements [i] .className == n) {

ClassElements [ClassElements.length] = allelements [i];

}

}

mengembalikan ClassElements;

}
