Could you please help me with this?

I have bought a script from a guy. It is here http://tools.950buy.com/rss-submit/

Unfortunately, the script will return all the services as "up and running", even though most of the sites it is supposed to ping are offline.

I believe this is the function that is wrongly codded and will return everything as functioning. It is added as a js script.

function URLSubmit(url,data,str){	
	$.ajax({
            url: url,
            type: 'POST',
			data: data,
			beforeSend:function(){
					$("#"+str+"_State").html("Please wait...");
				},
			complete:function(){
					$("#"+str+"_State").html("<img src='/images/right.gif'>");
				},
			success:function(msg){
			   if (msg!=""){			
			    $("#"+str+"_State").html("<img src='/images/right.gif'>");
			   }else{
				   alert(msg);
			   }
			  }
		});
	
}

Code (markup):

You can find it in http://tools.950buy.com/appcontent/themes/js/rss.js

Could you please check if what I say is true or not?

Thank you.
