How to install jquery.show/.hide without repeating div selectors

Question

I want to pass this function True or False and show the listed elements (true) or hide (false) at this input.

I am currently using this feature ...

        function SetElementVisibility(visible) {
        if (visible) {
            $("#Div1").show("slow");
            $("#Div2").show("slow");
            $("#Div3").show("slow");
        }
        else {
            $("#Div1").hide("slow");
            $("#Div2").hide("slow");
            $("#Div3").hide("slow");
        }
    }

But I would rather not repeat myself, naming a Div for each result.

How can I reorganize this into more DRY (don't repeat myself)?

Thanks Cohan

Answer 1

Use quadratic notation to select a method name depending on a variable visible:

$('#Div1, #Div2, #Div3')[visible? 'show' : 'hide']('slow');

Answer 2

This should work:

function SetElementVisibility(visible) {
   $("#Div1,#Div2,#Div3")[visible]("slow");
}

// Display all
SetElementVisibility( "show" );

// Hide all
SetElementVisibility( "hide" );

"show" "hide" , true false, :

function SetElementVisibility(visible) {
   $("#Div1,#Div2,#Div3")[visible?'show':'hide']("slow");
}

// Display all
SetElementVisibility( true );

// Hide all
SetElementVisibility( false );

$("ID").toggle()

id. :

function SetElementVisibility(visible) {
    if (visible) {
        $(".showHideDiv").show("slow");
    }
    else {
        $(".showHideDiv").hide("slow");
    }
}
