How to restart the Jquery events, to avoid the repetition of each one of them?

I have an index page that contains the following events.
<div id="sub_page"></div>
$(document).ready(function () {
$("a.menu_navegacion_abrircaja").on('click', function (ev) {
ev.preventDefault();
var href = “nombrecontrollerEJ/view_ej";
$.post(href, function (data) {
$("#sub_page").html(data);
});
});
});
In it, when you click, load the html contents of subpages in the div sub_page.
In view view view_ej, I bring html code and also, jquery code. The Jquery code of the view that is added to the index div is as follows:
$(document).ready(function () {
$('#modal_establecer_turnos').on('hidden.bs.modal', function () {
alert("hello");
});
});
By clicking on the link that contains the class "menu_navegacion_abrircaja", I get the alert ("hello");
But it turns out that there is a problem, for every time I click on the link, the alert messages are repeated (alert ("hello");). For example, the first time I click on the link that contains the class menu_navegacion_abrircaja, it works fine showing the alert once, but then I click again on the same link it shows me the alert twice, then I do it for the third time, He shows me three times the alert, and so on.
I would like to know how to solve this problem.
Will there be any way to restart the events or handler of the jquery, as are the events click, change, "hidden.bs.modal", etc., in such a way that their repetition of the events is avoided?
I have seen the methods unbind (), bind (), off (), which might be the solution, but if so, how could you apply them?

Maybe you could try something like this in the jQuery code of your subpage:
$(document).ready(function () {
$('#modal_establecer_turnos').off('hidden.bs.modal');
$('#modal_establecer_turnos').on('hidden.bs.modal', function () {
alert(“hello”);
});
});

Two OnClick events overlap, causing the first one to stop executing properly

I am trying to fit a new jQuery toggle function within an already working code. Basically, the toggle function should show/hide the below lying div form_fields_con with an onclick event.
The problem is that the form_fields_con div contains AJAX functionality triggered as well with an onclick event.
Toggle works when nothing in the form_fields_con div is changing but once clicked, the toggle function stops working.
This is the toggle function:
$(document).ready(function() {
$(".slidingDiv").hide();
$(".show_hide_search").show();
$('.show_hide_toggle').on('click', function(e) {
e.preventDefault();
var self = this,
sliding = $(this).closest('div').next('.slidingDiv').slideToggle(function() {
$($(self).children()[0]).text(function(_, txt) {
return txt == "–" ? "+" : "–";
});
});
});
});
And this is the AJAX one contained in form_fields_con div:
function selectcombobox(fuelcombobox, fuelid, fuelContainer, field_name) {
var popupvar = jQuery.noConflict();
popupvar('#'+fuelcombobox).css('display', 'none');
popupvar('#'+fuelid).css('display', 'block');
popupvar('#'+fuelContainer).css('display', 'none');
}

How to prevent the two onclick functions' collision?

You change/recreate the DOM elements holding the onClick listener, a simple approach to get around your problem is event-delegation: http://api.jquery.com/on/ (see se second argument)
$('.slidingDiv').on('click', '.select_con_car', function() {
alert('clicked');
});

jquery selectable and right click

I am using a jquery selectable as shown below.
//Selectable Functionality
$(document).ready(function () {
$("#Selectable_Positions").selectable({
selected: function (event, ui) {
dostuff();
}
})
})
It is working correctly however only left click will cause the select event to fire. I am trying to make it so that right click will as well. I have tried adding the code below and the alert fires but the selected item does not change.
$(document).ready(function () {
$('#Selectable_Positions').mousedown(function () {
$('#Selectable_Positions').trigger('selectableselected');
alert('foo');
})
})
How can I programatically change the selected item in the mousedown event function?
edit
Updated eventname as per Ian's suggestion below.
I have created a jsfiddle showing what I am trying to achieve and the triggered event not firing on right click. Does anybody know how to make this work? It would be greatly appreciated
http://jsfiddle.net/Jzjdm/

The correct event name is "selectableselected". So use:
$('#Selectable_Positions').trigger('selectableselected');
Reference:
http://api.jqueryui.com/selectable/#event-selected

Ended up writing my own select function and calling it on right click. Not sure what is up with that event.

Close popup div if element loses focus

I have the following scenario: On a label's mouseover event, I display a div. The div must stay open in order to make selections within the div. On the label's mouseout event, the div must dissappear. The problem is that when my cursor moves from the label to the div, the label's mouseout event is fired, which closes the div before I can get there. I have a global boolean variable called canClose which I set to true or false depending on the case in which it must be closed or kept open. I have removed the functionality to close the div on the label's mouseout event for this purpose.
Below is some example code.
EDIT
I have found a workaround to my problem, event though Alex has also supplied a workable solution.
I added a mouseleave event on the label as well, with a setTimeout function which will execute in 1.5 seconds. This time will give the user enough time to hover over the open div, which will set canClose to false again.
$("#label").live("mouseover", function () {
FRAMEWORK.RenderPopupCalendar();
});
$("#label").live("mouseout", function () {
setTimeout(function(){
if(canClose){
FRAMEWORK.RemovePopupCalendar();
}
},1500);
});
this.RenderPopupCalendar = function () {
FRAMEWORK.RenderCalendarEvents();
}
};
this.RenderCalendarEvents = function () {
$(".popupCalendar").mouseenter(function () {
canClose = false;
});
$(".popupCalendar").mouseleave(function () {
canClose = true;
FRAMEWORK.RemovePopupCalendar();
});
}
this.RemovePopupCalendar = function () {
if (canClose) {
if ($(".popupCalendar").is(":visible")) {
$(".popupCalendar").remove();
}
}
};
Any help please?

I would wrap the <label> and <div> in a containing <div> then do all you mouse/hide events on that.
Check out this fiddle example - http://jsfiddle.net/6MMW6/1

Give your popupCalendar an explicit ID instead of a class selector, e.g.
<div id="popupCalendar">
Reference it with #popupCalendar instead of .popupCalendar.
Now, remove() is quite drastic as it will completely remove the div from the DOM. If you wish to display the calendar again you should just .hide() it.
But your logic seems a bit overly complex, why not just .show() it on mouseenter and .hide() on mouseout events ?

This will close the entire tab page if the tab page loses focus.
How ever if you target it, it can work for something within the page too, just change the target codes.
JavaScript:
<script type="text/javascript" >
delay=1000 // 1 sec = 1000.
closing=""
function closeme(){
closing=setTimeout("self.close()",delay)
// self means the tab page close when losing focus, but you can change and target it too.
}
<!--// add onBlur="closeme()" onfocus="clearTimeout(closing)" to the opening BODY tag//-->
</script>
HTML:
<body onBlur="closeme()" onfocus="clearTimeout(closing)">

jQuery: Can't cache onclick handler?

I've got a step-by-step wizard kind of flow where after each step the information that the user entered for that step collapses down into a brief summary view, and a "Go back" link appears next to it, allowing the user to jump back to that step in the flow if they decide they want to change something.
The problem is, I don't want the "Go Back" links to be clickable while the wizard is animating. To accomplish this I am using a trick that I have used many times before; caching the onclick handler to a different property when I want it to be disabled, and then restoring it when I want it to become clickable again. This is the first time I have tried doing this with jQuery, and for some reason it is not working. My disabling code is:
jQuery.each($("a.goBackLink"), function() {
this._oldOnclick = this.onclick;
this.onclick = function() {alert("disabled!!!");};
$(this).css("color", "lightGray ! important");
});
...and my enabling code is:
jQuery.each($("a.goBackLink"), function() {
this.onclick = this._oldOnclick;
$(this).css("color", "#0000CC ! important");
});
I'm not sure why it's not working (these are good, old-fashioned onclick handlers defined using the onclick attribute on the corresponding link tags). After disabling the links I always get the "disabled!!!" message when clicking them, even after I run the code that should re-enable them. Any ideas?
One other minor issue with this code is that the css() call to change the link color also doesn't appear to be working.

I wouldn't bother swapping around your click handlers. Instead, try adding a conditional check inside of the click handler to see if some target element is currently animating.
if ($('#someElement:animated').length == 0)
{
// nothing is animating, go ahead and do stuff
}

You could probably make this a bit more concise but it should give you an idea... Havent tested it so watch your console for typeos :-)
function initBack(sel){
var s = sel||'a.goBackLink';
jQuery(s).each(function(){
var click = function(e){
// implementation for click
}
$(this).data('handler.click', click);
});
}
function enableBack(sel){
var s = sel||'a.goBackLink';
jQuery(this).each(function(){
var $this = jQuery(this);
if(typeof $this.data('handler.click') == 'function'){
$this.bind('goBack.click', $this.data('handler.click'));
$this.css("color", "lightGray ! important");
}
});
}
function disableBack(sel){
var s = sel||'a.goBackLink';
jQuery(s).each(function(){
var $this = jQuery(this);
$this.unbind('goBack.click');
$this.css("color", "#0000CC ! important");
});
}
jQuery(document).ready(function(){
initBack();
jQuery('#triggerElement').click(function(){
disableBack();
jQuery('#animatedElement').animate({/* ... */ }, function(){
enableBack();
});
});
});
