We still have to write try/catch statements without a jQuery construct. It would make more sense to use an abstraction function to do this. It would reduce the code size for plugins but also use console.log() correctly.

You would use as follows:

try script and log errors if possible

$.try(function() { error prone code });

try script and run a custom function on error

$.try(function() { error prone code }, function(error) { alert(error); });

//try and run a custom script on success to filter return value

$.try(function() {

return 'success';

}, function(r) {

if(r == 'success')

alert('I succeed!');

}, function(error) {

alert(error);

});

The console error still give the correct line numbers in Firebug but you reduce the extra code you have to write when you want to try some experimental code.

Here is the code for this:

$.try = function(testfn, okfn, errfn) {

if(!errfn) {

errfn = okfn;

okfn = null;

}

var r, rr;

try {

r = testfn();

} catch(error) {

if(window.console && window.console.log)

console.log(error);

if(errfn)

return errfn(error);

return error;

}

if(okfn)

rr = okfn(r);

if(typeof rr != 'undefined')

return rr;

return r;

};
