S2JS - Asking, Saying and Manipulating Text : Copying parts of strings

Another thing Scratch can't do -- copying portions of strings.

Use the substr method, passing in the position (or "index") of the first character you want, and the number of characters you want. Remember the first character of the string is character number zero.

Have a look at the examples below.

Can you change the example so it copies exactly the word "split" from the string?

<HTML> <body> <canvas id=myCanvas height=200 width=200 style="background-color: khaki"> </canvas> <script> var ctx = myCanvas.getContext("2d"); ctx.font="15px arial"; var word = "Banana Split"; ctx.fillText(word.substr(2,2), 0, 20); ctx.fillText(word.substr(0,6), 0, 40); </script> </body> </html>
