Question

I have this function which accepts obj (Jq object) as a parameter

However , in this function , I only need obj which is :not(:disabled) and :not([readonly]

currently I’ve managed to do it with :

function CheckRequiredSelection(obj)
{
    obj.find(".requiredSelection:visible:not(:disabled):not([readonly])").andSelf().each(function ()
    {
...
    });

}

But I really want to get rid of find and addSelf trick.

Any help ?

The document can contain :

Edit #1

…

<select class="requiredSelection">
...
</select>

<select class="requiredSelection">
...
</select>

and before submit : I do something like :

CheckRequiredSelection($(".requiredSelection"))

Edit #2

I could have check inside the .each loop but then it wont be efficient since it’s after the selector. ( instead of getting 5 filtered elements from 100 , I will get 100 elements and THEN i’ll have to filter. That’s not nice).

Answer 1

I think you want .filter().

function CheckRequiredSelection(obj)
{
    obj.filter(":visible:not(:disabled):not([readonly])").each(function ()
    {
...
    });

}
