Javascript .hover .show and .hide issue

Hi guys! Working with this piece of code:

$(".grid-item").hover( 
        function() {
            $( ".glyphicon.glyphicon-plus" ).show();
        }, 
        function() {
            $( ".glyphicon.glyphicon-plus" ).hide();
        })
});

I have multiple .grid-item on each page (grid layout) and it shows and hides the glyphicons on all of them if I hover over one of them. I need the glyphicon to only show on the current .grid-item that the user hovers over.

I've looked into .each and 'this' but I can't work it out.

How can I fix this? Thanks!

Hi Boris,

Can you show the html structure for one .grid-item?

You'll most likely want to use $(this) in combination with jQuery's tree traversal methods http://api.jquery.com/category/traversing/tree-traversal/

This will allow you to target the specific glyphicon that belongs to the .grid-item you're hovering over.

It depends on the relationship between the grid-item and the glyphicon.

Assuming the glyphicon is some descendant of .grid-item then this might work out for you:

$(".grid-item").hover( 
        function() {
            $(this).find( ".glyphicon.glyphicon-plus" ).show();
        }, 
        function() {
            $(this).find( ".glyphicon.glyphicon-plus" ).hide();
        })
);

You must use $(this)

Im sorry but as mentioned above, I was unable to figure it out myself using the $(this) method, so do you mind being more specific?

Thank you!

Thanks! Thanks to your answer I was able to figure out the rest myself. Here is the code I used:

//Plus icon hover effect nieuws grid items
$(".grid-item").hover( 
        function() {
            $(this).find( "span" ).show();
        }, 
        function() {
            $(this).find( "span" ).hide();
        }
);

note that in you code you had an }) to much, probably because you copied my code from above where I had it as well (-: Thanks!

You're welcome.

Thanks for the code correction. Yes, I copied and hadn't noticed it. :)
