javascript - bind and unbind function with a name -

i need bind , unbind function on click. problem need click event (also 'this' clicked element fine)

  function clickelement(e) {   [...]    //here need event or clicked element   }

this works, doesn't have event parameter

$('.clickme').on('click', clickelement)

this works can't unbind specific function

 $('.clickme').on('click', function(e){clickelement(e)})

this doesn't work:

 $('.clickme').on('click', clickelement(e))

why?

i need use .on instead of .click because later need unbind clickelement , clickelement this:

  $('.clickme').off('click', clickelement);

the first choice need

 function clickelement(e) {       console.log(e, this);         }    $('.clickme').on('click', clickelement);

the reason why

$('.clickme').on('click', function(e){clickelement(e)}) $('.clickme').off('click', function(e){clickelement(e)})

does not work because new anonymous function , not map 1 used in on(). if need that, have keep reference that.

var myfunc = function(e){clickelement(e); }; $('.clickme').on('click', myfunc ).data("fnc", myfunc);

and remove it

var elem = $('.clickme'); elem.off('click', elem.data("fnc") );
