Question

If I have a long string, lets say

var str = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean eu accumsan urna. Phasellus imperdiet elementum massa sit amet condimentum. Vivamus porttitor lobortis dignissim. Nam non tellus sapien, at pulvinar augue. Nulla metus mauris, cursus a sodales varius, imperdiet nec nisi. Quisque ut est quis massa sagittis pharetra quis aliquam dui. Phasellus id nisi quis mauris ultricies tristique et ut orci.";

and I want to manipulate it to display it something like this

"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean eu..."

How can I do that?

Answer 1

You can do this with simple javascript string manipulation.

var limit = 30 //or wherever you want to cut it off
str = str.substring(0, Math.Min(limit, str.length)) + '...'

EDIT:
You do not need the Math.Min as javascript’s substring method will take care of the issue if the limit is longer than the string.

Note: This will append “…” even if your string is too short and is displayed in its entirety. See hunter’s answer for how to avoid this.
