提问by Max Port
I cant seem to click all of the class's
我似乎无法点击所有课程
document.getElementsByClassName('node closed')[0].click();
This works but will only click on the first class, I need this to click all of the classes named 'node closed'
这有效但只会单击第一个类，我需要它来单击所有名为“节点关闭”的类
Thanks
谢谢

[0]means only the first element of the node list returned by getElementsByClassName.
[0]表示仅由 返回的节点列表的第一个元素getElementsByClassName。
You have to do getElementsByClassNameand iterate through all the matched elements like shown below:
您必须执行getElementsByClassName并遍历所有匹配的元素，如下所示：
var el = document.getElementsByClassName('node closed');
for (var i=0;i<el.length; i++) {
el[i].click();
}

iterate the result in a loop and assign click to each elements:
在循环中迭代结果并将点击分配给每个元素：
var list=document.getElementsByClassName('node closed')
for(var i=0;i<list.length;i++){
list[i].click()
}

回答by Ganesh Pandhere
just remove [0] and it will access all matched elements as [0] points to first element only.
只需删除 [0] ，它将访问所有匹配的元素，因为 [0] 仅指向第一个元素。
