how to pass this array to my JQuery function?

Question

I have this function:

function activateControlFlow(arrayControl) {
    $.each(arrayControl, function(){
        console.log(this);
        $(this).css({color:'#FFF', cursor: 'pointer'});  
    }); 
}

and I don't understand why if I pass to this function only one item, prints me that item as the array. Here is my example:

activateControlFlow(["a#nexth"]);

and in the console it prints this:

String {0: "a", 1: "#", 2: "n", 3: "e", 4: "x", 5: "t", 6: "h"}

WHY???

Can you give a example of arrayControl value being passes? are you sure its an array of dom objects? — Rummy

yes It was an array of Objects, But I didn't know how to do it — Monica

A perfectly legitimate question. Just phrased in an odd way. — redolent

The problem is that you're using this instead of a parameter of a function, as defined in the jQuery API (http://api.jquery.com/jQuery.each/)

function activateControlFlow(arrayControl) {
    $.each(arrayControl, function(index, value){
        console.log(value);
        $( value ).css({color:'#FFF', cursor: 'pointer'});  
    }); 
}

I would also suggest changing the variable's name from "value" to "selector"

So I was using 'a#nexth' instead of $('a#nexth'), which obviously I was sending a string instead of the Object itself.

So it should be like this:

activateControlFlow([$('#nexth')]);

It might be easier not using the jQuery objects. Consider: activateControlFlow(['#nexta', '#nextb', '#nextc']) instead of activateControlFlow([$('#nexta'), $('#nextb'), $('#nextc')])
