I've been trying to implement an overflow check when hovering over a div. The issue arises because I'm using jQuery for the hover function and then simple JavaScript for the overflow check in the next step. It seems that directly using an if-then statement inside a jQuery function does not work as intended. However, I still need the action to trigger the if-then statement when hovering over the div. Can someone provide assistance with this? =)
So the flow is jQuery (hover) -> JS (check overflow) -> jQuery (add to div (in this case: "...read more..."))
HTML:
<div class="hover_cap">
<div class="hcd">
Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum
</div>
</div>
CSS:
.hover_cap {
width:150px;
max-height: 17.5ex;
border: 1px solid red;
}
.hcd {
line-height:2.5ex;
max-height:12.5ex;
margin: 10px;
border: 1px solid green;
overflow: hidden;
}
.readmore {
padding: 0px 10px 10px 10px;
}
JS:
$('.hover_cap').hover(
// Check for overflow condition
if (function checkOverflow(hcd) {
var curOverflow = hcd.style.overflow;
if (!curOverflow || curOverflow === "hidden") hcd.style.overflow = "visible";
var isOverflowing = hcd.clientWidth < hcd.scrollWidth || hcd.clientHeight < hcd.scrollHeight;
hcd.style.overflow = curOverflow;
return isOverflowing;
}) {
// Execute these functions when hovering over the div
function() {
$(this).append($('<a>...read more...</a>'));
},
function() {
$(this).find("a:last").remove();
}
}
}
