Picture a scenario where a website contains an element that needs to be filled with random text using JavaScript. Once the div is completely filled, it should reset and begin again. It may sound odd, but the question is: how will the JavaScript determine when the div is full and starts to overflow?
When I say 'full', I mean that no more visible text can fit in the div – essentially, the moment when a scrollbar would appear.
One potential solution is to place the text within a nested div element that shares the same fixed width as the container, but does not have a fixed height. This way, the inner div can expand based on its content, and you can monitor when its height nears the fixed height of the parent div.
One way to determine if a div is 'overflowing' is by comparing its actual height with the height defined in the CSS.
if(document.getElementById('div').offsetHeight >
document.getElementById('div').style.height) {
//do something
}
When working with a fixed height div, make sure to apply the overflow:hidden style and verify the div.scrollHeight property.
if(myDiv.scrollHeight > myDiv.offsetHeight) { /* the div is completely filled */ }
else { /* there is still space available */ }
It’s impossible to predict if adding more content will result in overflow... it could be as simple as a single letter i, or even a series of invisible zero-width-spaces. The only way to know for sure is by adding the text and checking for overflow afterwards.
var hasOverflowed = div.offsetHeight < div.scrollHeight;
// roughly speaking... accounting for borders
To determine the exact count, try tallying up the characters inside the div element. Depending on how the content is being inputted (typing or other method), consider using onkeyUp event or another relevant listener to accurately track the character count.
