Question

I have a text say “A sample text for testing”. I need to display only ten characters in a div.
so i do substring on the text

txt.substring(0,10) 

This gives me “A sample t”. Since its ugly to display a unterminated word, i need only to display “A Sample” to be displayed. How do i do this?

Answer 1

You could do what you do, substringing the text to 10 chars.

Then you use txt.lastIndexOf(‘ ‘) to find the last space in the text.

Then you use that to substring the text again.

Example:

var txt = "A Sample Text";
txt = txt.subString(0,10); // "A Sample T"
txt = txt.subString(0, txt.lastIndexOf(' ')); // "A Sample"

Let me know if it helps!
