I have a function where I would like to call classList methods dynamically, something like this:
function expand(action) {
searchContainer.classList[action]("expanded");
}
button.addEventListener("click", expand('add'), false);
searchContainer.addEventListener("onblur", expand('remove'), false);
But not sure how can I do that?

I have a question. Why when I'm using anonymous function and I want to call it immediately i have to do like that:
(() => {console.log('something')})()
But when I want to use it with setTimeout for example, I don't have to use '(' at beginning and '()' at the end?
setTimeout(() => {console.log('something')}, 2000)
You pass the function as a parameter to setTimeout, rather than calling it right away. That's why you don't need the () at the end

You can just type onclick="ConfirmDelete(this.id) and it will be sent to your function.
and in function definition;
function ConfirmDelete(var_id)
{
alert (var_id);
}

Javascript dynamically invoke object method from string
(5 answers)
Closed 8 years ago.
I want to use a method in which i will pass a function_name as parameter to another function.
On the other function, the parameter will be treated as a function
here's my code example
<div class="btn_crt_acct" onclick="toggle_object('register_div','slideDown');">
CREATE AN ACCOUNT
</div>
whch will call a function like this
function toggle_object(obj,fun)
{
$('#'+obj).fun('slow');
// fun => slideDown
// so $('#'+obj).fun('slow'); => $('#'+obj).slideDown('slow');
}
but i am doing something wrong as it states an error in console, $fun(..) is not a function.
How can i make it work perfectly??
Thanks
You'd do that with bracket notation
$('#'+obj)[fun]('slow');
FIDDLE
But why not use a proper event handler, and slideToggle if you intend to toggle it
$('.btn_crt_acct').on('click', function() {
$('#register_div').slideToggle();
});
