javascript - Generating ellipsis AND "Read more" link with CSS

Question

[Update] It's different from this question because it's not only asking for text truncation; as i mentioned, i already have text truncation using this approach. Rather it's asking about having "read more" link only when text is truncated (using CSS only if possible).

Currently i'm using this approach to generate ellipsis when text overflows (when it cannot fit into one line). However, now i also want to include a 'Read More' link at the end of the line when overflow occurs and clicking that link will display all the content over multiple lines. Is this doable with CSS only?

btw, i saw this post, which displays "more" link no matter text has overflown or not, which is not what i want.

I guess the last resort would be using javascript with a resize() listener that dynamically hides the overflown portion of the text and creates the link to show them.

Thanks!

You will need JS for this. You can do something like this in jQuery:

var str = "this is some truncated te..."; //Your string to eval
var n = str.search("..."); //look for the elepsis 
if (n ==="" || n === null){ //if the elepsis is not found in the string
   $(".foo").hide(); //hide your read more link
}else{
   $(".foo").show(); //show your read more link
}

Note: this answers the second part of your question - the first part was answered by another poster.
