Question

Hey weird question but I am writing some code and I want to clean it up… The code goes as follows…

function (item){
    if(item == "1")
        $('div').show();
    if(item == "2"
        $('div1').show();
}

I tried something like

function (item)
   var $div = div+item;
   $($div).show()

Thanks

Answer 1

function (item){
    $("#div" + (item > 1 ? (item - 1) : "")).show();
}

Assuming you mean #div + n, since div1 is not a valid selector. However, the logic should be the same no matter what the prefix of your actual selector is.
