Select all class's with getElementsByClassName and click

Question

I cant seem to click all of the elements.

document.getElementsByClassName('node closed')[0].click();

This works but will only click on the first element. I need this to click all of the elements with class 'node closed'.

Thanks

Answer 1

[0] means only the first element of the node list returned by getElementsByClassName.

You have to do getElementsByClassName and iterate through all the matched elements like shown below:

var el = document.getElementsByClassName('node closed');
for (var i=0;i<el.length; i++) {
    el[i].click();
}

Answer 2

iterate the result in a loop and assign click to each elements:

var list=document.getElementsByClassName('node closed')
for(var i=0;i<list.length;i++){
list[i].click()
}
