Prototype - truncate() Method
This method truncates a string to the given length and appends a suffix to it (indicating that it is only an excerpt).
If unspecified, the length parameter defaults to 30 and the suffix to "...".
Syntax
string.truncate([length = 30[, suffix = '...']]) ;
Return Value
Returns a truncated string.
Example
<html> <head> <title>Prototype examples</title> <script type = "text/javascript" src = "/javascript/prototype.js"></script> <script> function showResult() { var str = 'A random sentence whose length exceeds 30 characters.'; alert("str.truncate() : " + str.truncate() ); alert("str.truncate( 10 ) : " + str.truncate(10) ); alert("str.truncate( 10, '...') : " + str.truncate(10, '...') ); } </script> </head> <body> <p>Click the button to see the result.</p> <br /> <br /> <input type = "button" value = "Result" onclick = "showResult();"/> </body> </html>
