Onclick starts without clicking

Question

en.onclick = setCookie('english');

Why does it start without even clicking on it?

I have 3 checkboxes that should set a cookie in their language when they click on the last one, which always fires immediately ...

Answer 1

Your code above evaluates setCookie('english') and puts its return value (if any) in en.onclick . To assign it as an event handler, wrap it in a function:

 en.onclick = function(){ setCookie('english'); }; 

Answer 2

you should use something like this

 en.onclick=function(){ setCookie('english'); } 

Answer 3

Because you are calling the setCookie(...) method. Try the following:

 en.onclick = setCookie; 

Using parentheses, you call the method; without you passing it as an object.

Or try the following:

 en.onclick = function() { setCookie('english') }; 

Here we create a new function that calls setCookie with the appropriate argument.

Answer 4

Good, because you use the method and assign the result to en.onclick.

What you probably want to make us

 en.onclick = function(){setCookie('english');};
