Question

i’m kinda of a newbie in javascript, even though i built so far lots of working website and apps..

btu i feel naive the way i used to pass the variable id to jquery..
for instance i used to do like this epsecialy when i have to work with some old code
..
let’s assume that i have all my website already coded with ‘a’ tags like this

<a id='myId' onclick='doSome(this.id)' > link </a>

and then in JS

function doSome(id){

//old code removed and replaced by jquery
    jQuery("#"+ id).show();

}

and the function in that way works flawless…

so, again, assuming that i cannot change anything else than the code inside the function what’s the best way to use the variable id?
because as far as i know if I had used just

jQuery(id).show();

instead of

jQuery("#"+ id).show();

it wouldn’t have worked…right?

Answer 1

Instead of passing this.id, pass this

Then you can call the function like:

$(id).show();
