Jquery: Hide all children, then show a specific element

Question

I want to hide all child elements in a div. And then show a specific one passed on to the function.

function subDisplay(name) {
   $("#navSub").each(function() {
      $(this).hide();
   });
   $(name).show();
}

then i call the function from an onmouse event like: subDisplay(#DivIwantToShow); But nothing displays...

What am i doing wrong?

Solution 1

You need to hide the children and not the containing div.

$("#navSub").children().hide();

So now if the div you are trying to show is an element in the parent div it will still show while the others stay hidden.

Solution 2

If you're targeting the children of #navSub, you need target them and hide them, rather than the element navSub; which you can do using the children() method;

function subDisplay(name) {
    $('#navSub').children().hide();
    $(name).show();
};

Otherwise, it appears you have multiple elements with the same ID in your DOM, which is not allowed.

You then need to pass a string (which is a valid jQuery selector) to subDisplay();

subDisplay('#DivIwantToShow');

Solution 3

if the name of the element is passed in name use this:

    if($(this).attr('name') != name){
    //Hide it
    } else {
   //show it
}

Solution 4

function subDisplay(name) {
   $("#navSub").hide();
   $('#'+name).show();
}

Solution 5

To summarize the great comments from @dotweb and @Matt;

function subDisplay(name) {
   $('#navSub').hide();
   $(name).show();
}

subDisplay('#DivIwantToShow');

Pretty simple and good, however, I would like to add that you can use toggle() for ease of life
