Question

I ve created a jQuery function called "onEnter". It works great on the run, but I need to trigger the event whenever I want. Somethink like this:

$(obj).onEnter(function(){ doSomething(); });

That works like a charm. Then I want to trigger:

$(obj).onEnter();

But this doesn t seems to work. Here s is my code. Thanks in advance.

$.fn.extend({
    onEnter: function(fn) {
        this.each(function() {
            new $.onEnter( this, fn );
        });
        return this;
    }
});

$.onEnter = function( obj, fn ) {
    if(typeof fn ==  function )
    {
        $(obj).keypress(function(e){
            if(e.which == 13)
            {
                e.preventDefault();
                fn(obj);
            }
        });
    };
    return;
};

我认为,你期待着使用。 Query .trigger(。

因此,你可以做这样的事情:

$( #foo ).bind( custom , function(event, param1, param2) 
{
  alert(param1 + "
" + param2);
});

$( #foo ).trigger( custom , [ Custom ,  Event ]);
