Often times, you will find yourself assigning many
properties to one particular movie clip. Let's say you have
a movie clip instance called theContent_txt. Adding
properties to it could look like this:
business is mine";
Notice how you are repeating the word theContent. A
better, cleaner method for referencing one particular object
would be to use the with() statement.
The with() statement calls an object once and allows you to
access all of the object's properties and methods with only
one reference. For example, using the with() statement, the
above lines of code can be written as the following:
"the business is mine!";
I refer to theContent_txt only once! The with()
statement may not be versatile enough to carry event
handlers, but it does the work of referencing almost any
class or object for you.
The following is an example of it working with the top
level class Mouse:
In the above code snippet, I used a top level class and
called its hide method.
You can also call nested objects inside the original
object. Here is a diagram to better help you visualize what
I am referring to:
The code for calling the secondObject object
using with() would be:
Here, I used a direct path to gain access to the
properties of the nested secondObject object.
So, there you have it. This is my quick, short take on
using the with() statement. Beyond simply providing
aesthetic value to your code, it helps you to easily group
together and recognize object assignments.
Thank you for your time. If you have any questions,
please post them on the forum.
