Dojo Dojo syntax issue

[Disco_Cowboy]

I am new to Dojo and tyrign out some code below. I am getting a syntax issue on line 9:

"a"{

Full code:

//Auto Download Tracking
/*Regex list of download file extensions, pipe and backslash delimited. Looks for the period before the file type so it will work on download links with query parameters after it */
var downloadTypes = /\.pdf|\.doc|\.xls|\.zip|\.csv|\.ppt|\.rtf|\.pptx|\.docx|\.xlsx|\.wmv|\.mpg|\.mov|\.avi|\.exe|\.mp3|\.wma|\.txt|\.rar|\.wav/i; 

/*Regex list of on-site domains, pipe and backslash delimited. */
var onsiteDomains = /bluecrossma\.|ahealthyme\.|livinghealthybabies\.|paramisalud\.|whygetit\.|indigo-insurance\.|healthy-actions\.|javascript|#/i;

dojo.behavior.add({
	"a"{
		onclick:function(dom){
			if( dom.href.match(downloadTypes) )
			ntptEventTag('ev=download&eventPage=Download From: ' + escape( wa.currentDomain + wa.currentURL ) + '&downloadFile=' + escape( dom )); 
			
			if(!dom.href.match(onsiteDomains) )
			ntptEventTag('lk=1&ev=Exit Link&eventPage=Exited From: ' + escape( wa.currentDomain + wa.currentURL ) + '&exitTo=' + escape(dom)); 
		};
	}
});
dojo.behavior.apply();

Is there a simple fix for this?

Thanks!

I think you are missing a colon:

"a" : {
