javascript - How do I use .split() to break up a string into much smaller strings? -
i making code supposed split alphabet each letter on different line. when press submit button, instead of displaying letters, absolutely nothing @ all. not sure why not working.
the output should be:
a:
b:
c:
d:
etc...
any appreciated, please not use jquery.
<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns:hi="http://www.w3.org/1999/xhtml"> <head> <title>my string prototype</title> </head> <body> <form action = "#"> <input type="submit" id = "sub" value="submit" onclick = "show_alphabet();"/> </form> <script type="text/javascript"> function show_alphabet () { var str = "abcdefghijklmnopqrstuvwxyz"; str.prototype.sendarray= function (){ str.split(""); }; var arr = str.sendarray(); (var i=0;i>arr.length;i++){ document.writeln(arr+":"); } } </script> </body> </html>thanks!
since looks homework, don't answer outright.
1) when split string, pick character split on. ex: splitting ("a b") (a space b). returns array 2 elements. & b.
2) don't need string prototype stuff see in online help. var arr = str.split(... works fine.
3) greater sign should less in loop. wnat repeat while less length, not greater.
4) don't want writeln arr. want writeln arr[i], or i'th element of array.
5) newline in html replace ":" "<br />"
