The
Console class defines five methods: log(), warn(), info(), error(), and dump().
The log(), warn(), info(),
and error() methods all let you send an object to
the Console tab. The most basic of these methods is the log() method.
The following code sends a simple object, represented by the test variable,
to the Console tab:
var test = "hello";
air.Introspector.Console.log(test);
However, it is more useful to send a complex object to the Console
tab. For example, the following HTML page includes a button (btn1)
that calls a function that sends the button object itself to the
Console tab:
<html>
<head>
<title>Source Viewer Sample</title>
<script type="text/javascript" src="scripts/AIRIntrospector.js"></script>
<script type="text/javascript">
function logBtn()
{
var button1 = document.getElementById("btn1");
air.Introspector.Console.log(button1);
}
</script>
</head>
<body>
<p>Click to view the button object in the Console.</p>
<input type="button" id="btn1"
onclick="logBtn()"
value="Log" />
</body>
</html>
When you click the button, the Console tab displays the btn1
object, and you can expand the tree view of the object to inspect
its properties:
You can edit a property of the object by clicking the listing
to the right of the property name and modifying the text listing.
The info(), error(), and warn() methods
are like the log() method. However, when you call
these methods, the Console displays an icon at the beginning of
the line:
Method
|
Icon
|
|---|
info()
|
|
error()
|
|
warn()
|
|
The log(), warn(), info(),
and error() methods send a reference only to an
actual object, so the properties available are the ones at the moment
of viewing. If you want to serialize the actual object, use the dump() method.
The method has two parameters:
Parameter
|
Description
|
|---|
dumpObject
|
The object to be serialized.
|
levels
|
The maximum number of levels to be examined
in the object tree (in addition to the root level). The default value
is 1 (meaning that one level beyond the root level of the tree is
shown). This parameter is optional.
|
Calling the dump() method serializes an object
before sending it to the Console tab, so that you cannot edit the
objects properties. For example, consider the following code:
var testObject = new Object();
testObject.foo = "foo";
testObject.bar = 234;
air.Introspector.Console.dump(testObject);
When you execute this code, the Console displays the testObject object
and its properties, but you cannot edit the property values in the
Console.
