Note that this only works if the container has a boundary to 100% of the available width (so if you are using flexbox, your container has to be flex: 1 for example.

If the element width are 150px and the scrollWidth are 150.4px (rounded to 150), then this check will be returning false even if the browser are showing ellipsis in the text. W3C has a legacy API that returns element.scrollWidth value as rounded which is causing the comparison in some cases to to return false. There's a small pixel problem with the answers above when comparing offsetWidth > scrollWidth. Then use it to find elements $truncated_elements = $('.my-selector:truncated') If you are viewing this in Firefox it will not work if you do not have Javascript enabled.

It can be clipped, display an ellipsis (.), or display a custom string. But it can be a bit awkward to just cut the text off like that. The text-overflow property specifies how overflowed content that is not displayed should be signaled to the user. Use the textOverflow property together with the overflow style property (with a value different.
Javascript text overflow ellipsis how to#
Once upon a time I needed to do this, and the only cross-browser reliable solution I came across was hack job. If we want to expose three lines of text, we can just make the height of the container 3.6em (1.2em × 3). Specifies or returns how to handle the overflowed area of text.
