2.7 Debugging a Viewsheet Script

When you attempt to debug a Viewsheet script, it is often helpful to view the current values of variables and objects. To do this, use the alert() function, which opens a dialog box to display a specified string.

alert('string to display')

Note: The alert() function does not pause script execution.

For example:

var arr = ['Sue','Robert','Eric'];

alert(arr.join(","))

 

You can also use the alert() dialog box to display critical information to a user (e.g., that the user's selections have resulted in an empty dataset being returned).
