=head1 DESCRIPTION |
49
|
|
|
|
|
|
|
|
50
|
|
|
|
|
|
|
Adds a debug panel that logs ajax requests and responses through jQuery, as |
51
|
|
|
|
|
|
|
they happen. Only ajax requests that go through jQuery are logged, because the |
52
|
|
|
|
|
|
|
logging relies on jQuery's global event handlers. If you make an ajax call with |
53
|
|
|
|
|
|
|
global set to false, the event won't be logged: |
54
|
|
|
|
|
|
|
|
55
|
|
|
|
|
|
|
$.ajax({ |
56
|
|
|
|
|
|
|
// ... |
57
|
|
|
|
|
|
|
global: false, |
58
|
|
|
|
|
|
|
}); |
59
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
You could use this feature to selectively log messages, if you don't make use |
61
|
|
|
|
|
|
|
of global ajax event handlers elsewhere. |
62
|
|
|
|
|
|
|
|
63
|
|
|
|
|
|
|
Note that ajax events are logged as they happen, so responses won't necessarily |
64
|
|
|
|
|
|
|
appear directly above their respective requests. Events are shown newest first. |

|
|
Limit the number of logged ajax requests and responses to the specified number. |
73
|
|
|
|
|
|
|
When the log exceeds this size, the oldest items are deleted to make room for |
74
|
|
|
|
|
|
|
new items. The default limit is 50, to avoid hogging memory with large |
75
|
|
|
|
|
|
|
responses. |
