我正在编写HTML CSS JS代码,我正在尝试更改一组元素的样式。我已经了解了document.getElementById(id).style.something ='somevalue';但它需要我写出其中的25个并且有25个不同的ID。我想知道是否有办法改变类中的样式属性。例如:
CSS代码:
div.text
{
width: 100px;
}
HTML code:
<div class="text">Some Text</div> <!-- and bunch of other divs like it !>
JavaScript代码:
function changeWidth() {
document.getElementsByClass('text').width = '200px';
// I know getElementByClass doesn't exist I wanna know if there is something that would do that.
}
