Replace innerHTML of all divs with same class
提问by lisovaccaro
I want to replace the innerHTML of all divs with class "count" with: items1.innerHTML.
我想用“count”类替换所有div的innerHTML:items1.innerHTML。
How can I do this?
我怎样才能做到这一点?

Here you go:
干得好:
var items = document.getElementById( 'items' ),
divs = document.getElementsByClassName( 'count' );
[].slice.call( divs ).forEach(function ( div ) {
div.innerHTML = items.innerHTML;
});

现场演示:http : //jsfiddle.net/MGqGe/
I use this [].slice.call( divs )
to transform the NodeListinto a regular array, so that I can call the forEach
method on it.
我使用它[].slice.call( divs )
来将NodeList转换为常规数组,以便我可以调用forEach
它的方法。
Btw, careful with innerHTML. I personally would use a library (like jQuery) to clone the contents instead.
顺便说一句,小心 innerHTML。我个人会使用一个库(如 jQuery)来克隆内容。

you can do this by jQuery this way
你可以通过 jQuery 这种方式做到这一点
$("div.count").html("new content");
