|
|
* This function provides a simple assertion function for JavaScript.
|
|
* If the condition is true, this function will do nothing. If the
|
|
* condition is false, then the message will be printed to the console
|
|
* and an alert will appear showing a stack trace, so that the (alpha
|
|
* or nightly) user can file a bug containing it. For future enhancements,
|
|
* see bugs 330077 and 330078.
|
|
*
|
|
* To suppress the dialogs, you can run with the environment variable
|
|
* XUL_ASSERT_PROMPT set to 0 (if unset, this defaults to 1).
|
|
*
|
|
* @param condition represents the condition that we're asserting to be
|
|
* true when we call this function--should be
|
|
* something that can be evaluated as a boolean.
|
|
* @param message a string to be displayed upon failure of the assertion
