angularjs - Unused 'x' in function arguments, but 'x' is needed - JSLint error -

i'm analyzing angularjs code jslint.

many times, have function have multiple argumets, eg:

$rootscope.$on('$statechangesuccess', function (ev, tostate, toparams, fromstate, fromparams) {     // code uses tostate, toparams, fromstate, fromparams     // touch use ev }) 

and many times need specify arguments, because use last arguments.

as result other arguments not used, still needed. , jslint throws errors, eg:

unused 'ev'.......

is there way fix it?

sure! can use jslint directive:

/*jslint unparam:true, sloppy:true, white:true, devel:true */ /*global $rootscope*/ $rootscope.$on('$statechangesuccess', function (ev, tostate, toparams, fromstate, fromparams) {     // i'm putting in line jslint doesn't complain empty block     // , can mimic described situation.     console.log(tostate, toparams, fromstate, fromparams); }); 

in case, unparam:true 1 fixes specific issue. (devel allows console use , few other objects. white allows whitespace, , sloppy allows skip "use strict";. last 2 personal preferences.)

if want turn off single function (or subset of code), can turn unparam off , on this:

/*jslint sloppy:true, white:true, devel:true */ /*global $rootscope*/  /*jslint unparam:true */ $rootscope.$on('$statechangesuccess', function (ev, tostate, toparams, fromstate, fromparams) {     console.log(tostate, toparams, fromstate, fromparams); }); /*jslint unparam:false */ 

unparam useful these kinds of situations. event handler function signatures 1 in 3rd party libraries difficult use without option.
