i want a neat solution to handle event for a drop down menu , so that when user opens the select menu , it alerts opened , and when he closes it , it alerts closed , neglecting wheather the selected value is changed or not.
<select id="dummy">
<option>dummy1</option>
<option>dummy2</option>
<option>dummy3</option>
</select>
what i want is something like
$("#dummy").on('open',function(){//do something})
$("#dummy").on('close',function(){//do something})
something like heapbox /
and this solution is not acceptable : Run change event for select even when same option is reselected

How about telling us what you've actually tried? – monners Commented Dec 2, 2013 at 5:44

- 1 use a select plugin....events regarding select tag are difficult, particularly in IE. You are going down a road others have been down for years....and that's why plugins showed up that are more event friendly. Not to mention they can be styled as well – charlietfl Commented Dec 2, 2013 at 5:49

Reset to default 2the typical approach to extending the native functionality of a select box is to replace it with styleable markup and then tie the values of the new markup back into the origninal (now hidden) select element. (NOTE: I've not included any styles. This is a bare-bones example of using a select replacement).
var SelectBox = {
init: function () {
if ($('select').length > 0) {
this.generateStyledSelectbox('custom-select');
};
},
generateStyledSelectbox: function (cssClass) {
// Contained within .each to isolate all instances of <select>
$('select').each(function(index) {
var $source = $(this),
selected = $source.find("option[selected]"),
options = $source.find('option'),
selindex = index;
// Append styleable pseudo-select element to doc
$source.after('<div id="result-' + index + '" class="' + cssClass + '"></div>');
// Construct select list in pseudo select element
$('#result-' + index).append('<dl id="activeValue-' + index + '" class="dropdown"></dl>');
$('#activeValue-' + index).append('<dt><a href="#">' + selected.text() + '<span class="value">' + selected.val() + '</span></a></dt>');
$('#activeValue-' + index).append('<dd><ul></ul></dd>');
// Assign select values to pseudo-select lis items
options.each(function () {
$('#activeValue-'+ index + ' dd ul').append('<li class="select-menu-item"><a href="#">' + $(this).text() + '<span class="value">' + $(this).val() + '</span></a></li>');
});
$('.dropdown').each(function(index) {
$(this).find('dd ul li a').on('click', function(event) {
event.preventDefault();
var text = $(this).not('.value').html(),
$base = $('.custom-selectbox').eq(index);
$('.dropdown').eq(index).find('dt a').html(text);
$('.dropdown').eq(index).find('dd ul').hide();
$base.val($(this).find('span.value').html());
});
});
// prevent link actions in dropdown
$('.dropdown dt a').on('click', function (event) {
event.preventDefault();
});
// open/close
$(".dropdown").eq(index).find('dt a').on('click', function () {
$(".dropdown").eq(index).find('dd ul').toggle();
});
$(".dropdown").eq(index).find('dd ul li a').on('click', function () {
var text = $(this).html(),
newval = $(this).find('.value').html();
$(".dropdown").eq(index).find('dt a span').html(text);
$('select').eq(index).val(newval);
$(".dropdown").eq(index).find('dd ul').hide();
});
// Hide dropdown on outside click
$(document).on('click', function (e) {
var $clicked = $(e.target);
if (!$clicked.parents().hasClass("dropdown")) {
$(".dropdown").eq(index).find('dd ul').hide();
}
// remove dropdown-open targetable class
if (!$clicked.parents().hasClass("dropdown-open")) {
$clicked.parents().removeClass('dropdown-open');
}
});
// Hide native select
$source.css('display', 'none');
// assign initial (default) value
var initialval = $source.find('option').eq(0).html();
$('#activeValue-'+index+' dt a').html(initialval);
}); // END .each
}
};
SelectBox.init();
Here's a fiddle http://jsfiddle/P6ZCn/ (again, without styles)
