Syntax
| ASP.NET Ajax Javascript (Specification) | |
|---|---|
function get_debug() : Boolean function set_debug(value : Boolean) | |
| ASP.NET Ajax Javascript (Usage) | |
|---|---|
var resultVar = instanceOfPageView.get_debug(); | |
Example
This JavaScript code will turn on logging and set the level to log exceptions, calls to viewer functions, and calls to change the value of viewer properties:
If using Microsoft Ajax
var viewer1 = $find('viewer1');
viewer1.set_debugErrorLevel(ImageGear.Web.UI.DebugErrorLevel.Development);
viewer1.set_debug(true);
If using ImageGear jQuery plugins
$("#viewer1").ImGearPageViewPlugin().set_debug(true);
This JavaScript code implements the onImageGearItemLogged function, which will automatically receive items that any Accusoft control logs.
| JavaScript |  Copy Code |
|---|---|
function onImageGearItemLogged(logItem) { // logItem.message is the text of the log entry. // logItem.cause is the cause of the logged item. It will be one of the values in the enumeration. // logItem.level is the debug level of the logged item. It will be one of the values in the enumeration. // logItem.id will be the client ID of the control that issued the log entry. } | |
Remarks
This property turns the control's logging on or off. If you set this to true, the control will log its activities via the ASP.NET client-side trace facility.
You can set the amount of information that the viewer will log using the debugErrorLevel property.
The ASP.NET client-side trace facility is documented in MSDN, but to summarize, the client framework will send trace text to the following locations:
- A textarea element on your page with an id of "TraceConsole"
- The IE8 Developer Tools Console window
- The FireBug Console window
- The Visual Studio Output window
In addition to the locations that the ASP.NET client-side trace facility sends trace text, this control will send all logged items (with the data to be logged in an LogItemEventArgs object) to a global function, if it is present. In order to use this facility, you need to define a global JavaScript function in your client page called "onImageGearItemLogged".
