Webform client debugging tool log4javascript

I accidentally found this little Dongdong when I checked the information on the Internet. I found not much information in my blog. I wrote it here, hoping to bring convenience to more friends.

Literally, it is a log recording tool used on the webform client. We can avoid adding a window when debugging is required. alert () method to view the debugging result. is it very similar to log4j and log4net? Yes, it was designed according to this class library and supports multiple browsers.

The parameter of the ajaxappender method is URL, that is, the background page address. I thought I could write logs directly. if degub is used, the information of the degub string is directly transmitted to the background. if the method shown in figure-3 is feasible, isn't it superfluous? If you are interested, you can continue to study it!
