[webmap-discuss] Javascript debug libraries?

[Paul Spencer]

Conveniently, Safari will respect console.log() calls as well,  
dumping the output into the javascript console.

Inconveniently, IE doesn't.  I use the following to map console.log  
in IE after the onload event and use #console in CSS to show/hide and  
style the div

//IE compatibility for logging stuff
if (typeof console == 'undefined' || !console) {
     console = document.createElement('div');
     console.id = 'console';
     console.log = function(s) {this.innerHTML = s+"<BR>" +  
this.innerHTML};
     document.body.appendChild(console);
}

Cheers

Paul
