Divs may not be properly receiving click events and CSS attributes due to their padding-heavy nature

I am attempting to add click events to a few div elements. One of them has borders but no height or width. It seems like the clicks are not consistently registering, possibly due to browser issues. Even using the CSS rule .class:hover{} does not seem to solve the problem.

$("body").on("click", "._tlh_dropdown, ._tlh_dropdown *", function (event) {

The click event does not seem to work properly when clicking on a div inside ._tlh_dropdown. Additionally, clicking on the div ._tlh_dropdown_close_button does not remove its parent div as expected, nor does it change color when hovered over. What could be causing this issue? I suspect it has to do with the click event not being applied to the padding areas of the divs. How can I resolve this problem?

Answer №1

The reason behind this issue is the overlapping of the underline element, which is a div element, with the elements in question. Remember that div is a block level element.

One way to resolve this is by setting both divs to inline-block

._tlh_dropdown_input_container, ._tlh_dropdown{
    display: inline-block;
}

View Fiddle for hover effect

If you prefer to keep the div as a block level element, you can also manipulate the z-index property 

._tlh_dropdown_close_button{
     z-index: 1;   
}

This will ensure the close div remains on top of the underlying container

UPDATE

For every click event on the page, two events are triggered..

Hence, the content does not appear when clicking on the image due to this condition

if ($targ.hasClass('_tlh_dropdown') 
      || $targ.closest('._tlh_dropdown_content').length)

return;

This occurs because the e.target when clicking on the arrow image is the arrow itself and not the tlh_dropdown .. Therefore, it fails on this condition and proceeds to remove the content.

Modify it like this 

if ($targ.hasClass('_tlh_dropdown') 
       || $targ.closest('._tlh_dropdown').length  
       || $targ.closest('._tlh_dropdown_content').length) 
 return;

It should now function correctly..

In addition, achieving the same result with less code is possible. You can have the HTML structure already in place and then show or hide based on conditions.

Answer №2

When examining the close button, it becomes apparent that when hovering over "_tlh_dropdown_input_container" in the inspector, there is an overlap with the lower portion of the X button. This results in the hover/click event on the X not being registered below its midpoint.

To address the issue with the down arrow, a solution could involve wrapping it within another DIV element where events can be added. This minimizes the amount of HTML needed by utilizing a single DIV and incorporating the arrow using CSS :before or :after.
