Use the Change Property behavior
to change the value of one of an object’s properties (for example,
the background color of a div or the action of a form).
Note: Use
this behavior only if you are very familiar with HTML and JavaScript.
Select an object and choose Change Property from
the Actions menu of the Behaviors panel.
From the Type Of Element menu, select an element type
to display all the identified elements of that type.
Select an element from the Element ID menu.
Select a property from the Property menu, or enter the
name of the property in the box.
Enter the new value for the new property in the New Value
field.
Click OK and verify that the default event is correct.
If not, select another event or change the target browser in the
Show Events For submenu.
