Question

In this abbreviated code, the inline event works – the ‘event’ is passed to the testKeyPress function

<textarea id='source'     onkeydown= 'showCursPos(this);      var tf=testKeyPress(event);     document.onkeypress=function(){return tf};     document.onkeydown=function(){return tf}; ' ></textarea>  function testKeyPress(e){     if (e.ctrlKey==true ){         if (e.which == null ){kcode=e.keyCode; }  // IE         else if (e.which > 0){kcode=e.which; }    // gecko         return testValidity(kcode);   //returns true-false     } } 

However, in this anonymous version, the event is not passed in gecko:

<textarea id='source'></textarea>  $('source').onkeydown = function(){      showCursPos(this);  // this function works     // next event is passed in IE, but not gecko     var tf=testKeyPress(event);      // remaining functions work if value is forced     document.onkeypress=function(){return tf};      document.onkeydown=function(){return tf};      } 

How does one pass the function’s own event?

Answer 1

Yes, there is an event object as arguments.

You can get it by

var e=arguments[0] || event; // Firefox via the argument, but IE don't 

I don’t know if they exact the same, but I read <xxx onkeydown='func(event);'> as xxx.ononkeydown=function(event){func(event);};
