Basic JavaScript for loop

March 6, 2010 - 9:49pm

This is a very simple script that shows how a basic for loop works. We have an HTML document with 10 empty divs, all given an ID 0-9. (Remember that JavaScript is 0 based so numbers basically always start at 0 and it's a good idea to just conform rather than fight it). Our script uses a for loop to create a random number and insert it into the DIVs. Check the notes in the script to see in more detail how a for loop works.
