window is not loading immediately after clicking a link

When I click an anchor link, the current page should be loaded again immediately:
<a href="javascript:void(0);" class="BackToFirst"
onclick="popNav('BackToFirst');">Back</a>
function popNav(type) {
if(type == "BackToFirst") {
$(".first").show();
$(".second").hide();
$('.BackToFirst').click(function() {
document.location.href = window.location.href;
});
}
}
I expect that when a user clicks on the link, the current page will load immediately but it is taking some time to load.

It is unclear what you are trying to do.
show/hide is immediately undone when you reload the page
it is recommended to use location.reload(1) instead of setting the supposedly read-only document.location
you might want to use e.preventDefault instead of the javascript void
Are you absolutely sure this is not an X/Y problem? Can you explain the actual usecase?
var current = sessionStorage.getItem("which"); // does not run in a snippet
current = current ? current.split("|") : []
if (current.length) {
$("." + current[0]).show();
$("." + current[1]).hide();
}
$(".BackToFirst").on("click", function(e) {
e.preventDefault();
$(".first").show();
$(".second").hide();
sessionStorage.setItem("which", "first|second")
setTimeout(function() {
location.reload(1); // are you absolutely sure this is not an X/Y problem?
}, 500); //let the show/hide sink in
});

Your Click handler is only assigning a new click handler to the link, try this which just directly navigates:
function popNav(type){
if(type=="BackToFirst")
{
$(".first").show();
$(".second").hide();
document.location.href = window.location.href;
}
}
I think that you got two concepts mixed up, the above code attaches a DOM event to the link directly on it, the other way would be to use JQuery to attach an event to that button like so:
HTML:
Back
Script:
$('.BackToFirst').click(function(){
$(".first").show();
$(".second").hide();
document.location.href = window.location.href;
});
If you still want to check the type then data attributes are a nice way to go when working with JQuery:
Back
$('.BackToFirst').click(function(){
if($(this).data('linktype') == 'BackToFirst'){
$(".first").show();
$(".second").hide();
document.location.href = window.location.href;
}
});

I think you are overcomplicating your code. You are binding onClick after you click on the element. I think something like this should be better.
HTML:
Back
JS:
function onClickHandler(type){
if(type !== 'BackToFirst') {
return;
}
$(".first").show();
$(".second").hide();
location.reload();
}

Prevent anchor click after one click

I am facing one issue, I want to disable anchor click after one click. I have
on-click attribute set in my anchor tag. Below is my HTML
<a style="cursor:pointer;" id="someId" onclick="Myfuntion()">Verify</a>
After I click "Verify" I am changing anchors text to "Verifying..." and one more thing I am trying to disable this anchor to avoid click in between the verification logic going on.
I have tried event.preventdefault() and also added disabled attribute to anchor.
But nothing works.
Please help!

If you were using jQuery for this you could have done this more easly.
Here we add a new class to a link to show that it has been clicked already. We check this when a click is made.
<a style="cursor:pointer;" id="someId">Verify</a>
$('#someId').on('click',function(){
//Check if button has class 'disabled' and then do your function.
if(! $(this).hasClass('disabled')){
$(this).addClass('disabled');
Myfuntion();
$(this).removeClass('disabled');
}
});

Here is a demo as to how it could be done using Javascript.
//Pass the event target to the function
function Myfuntion(elem) {
//If the element has no "data-status" attribute
if (!elem.getAttribute("data-status")) {
//Set attribute "data-status=progress"
elem.setAttribute("data-status", "progress");
//Change the text of the element
elem.textContent = "Verifying...";
//The setTimeout(s) below is only for the demp purpose
//Lets say, your verification process takes 4 seconds
//When complte
setTimeout(function() {
//Remove the attribute "data-status"
elem.removeAttribute("data-status");
//Notify the use that verification is done
elem.textContent = "Verified";
//Again, this is only for demo purpose
setTimeout(function() {
//User may verify again
elem.textContent = "Verify";
}, 1000);
}, 4000);
}
return false;
}
Link to the demo

There are plenty of ways to do this; one simple approach is to just redefine the function itself:
var myFunction = function() {
alert('clicked');
// do whatever your function needs to do on first click, then:
myFunction = function() { // redefine it
// to no-op, or to another action
alert('second click');
}
}
<a onclick="myFunction()">click me</a>

Javascript function interacts with other function

I am completely new to javascript (and jquery) and have been experimenting with drop down menus the past couple of days. I found this one fancy notification menu, and I tried to see what happens when I have two of them on the page. Anyways, I made a quick example of my problem here:
http://jsfiddle.net/rgt03mu4/24/
The problem is that I can have both notification containers open up if I click on both.
If I am already clicked on one of the bells, then I click on the other, it should close the other one. Instead it keeps it open, and even when you click on the other container one, it still doesn't close it. You have to click off the page or click the notification bells. I am trying to make it to where you can only have one open at a time. So in order to do this, I tried changing the names of the functions:
As you can see:
$(function() {
var nContainer = $(".notification-popup-container");
//notification popup
$("#notification-link").click(function() {
nContainer.fadeToggle(300);
return false;
});
//page click to hide the popup
$(document).click(function() {
nContainer.hide();
});
//popup notification bubble on click
nContainer.click(function() {
return false;
});
});
I added the next function to be called test(), which you would think, since it's an entirely new function it would work differently. Instead, the error still persists.
What am I doing wrong? I even gave the the new bell it's own divs and link name. I also renamed container to container2.

Set the global variable for your container:
var nContainer = $(".notification-popup-container");
var nContainer2 = $(".notification2-popup-container");
$(function() {
var nContainer = $(".notification-popup-container");
//notification popup
$("#notification-link").click(function() {
nContainer.fadeToggle(300);
nContainer2.hide(); //hide the second container
return false;
});
//page click to hide the popup
$(document).click(function() {
nContainer.hide();
});
//popup notification bubble on click
nContainer.click(function() {
return false;
});
});
And you can do same with other function.
DEMO

There is no need to give the popup containers different classnames.
I would give the a-tags a common classname instead of an id. The href can be used to identify the target popup, so the binding between the link and the target popup is set in the origin of action. The JS part would be abstracted and could be reused.
<a class='notification-link' href='#firstpopup'>X</a>
<a class='notification-link' href='#secondpopup'>X</a>
<div class='notification-popup-container' id="firstpopup">
... firstpopup
</div>
<div class='notification-popup-container' id="secondpopup">
... secondpopup
</div>
The click handler first hides all the popups before opening a new one.
$(".notification-link").click(function () {
$(".notification-popup-container").hide();
var targetId = $(this).attr('href');
$(targetId).fadeIn(300);
return false;
})
working example: http://jsfiddle.net/qyLekdwk/

The problem here is how the event propgation is handled
$(function () {
var nContainer = $(".notification-popup-container");
//notification popup
$("#notification-link").click(function () {
nContainer.fadeToggle(300);
});
//page click to hide the popup
$(document).click(function (e) {
if (!$(e.target).closest('#notification-link, .notification-popup-container').length) {
nContainer.hide();
}
});
});
$(function test() {
var nContainer2 = $(".notification2-popup-container");
//notification popup
$("#notification2-link").click(function test() {
nContainer2.fadeToggle(300);
});
$(document).click(function (e) {
if (!$(e.target).closest('#notification2-link, .notification-popup-container').length) {
nContainer2.hide();
}
});
});

How to disable the click if a function is in active status

I have created a fiddle of my function here( http://jsfiddle.net/rhy5K/10/ ) . Now i want to disable the button click i.e play/pause if the sound is playing like Get ready,5,4,3,2,1 .
I know only how to disable the form submit button , but I am very confused how to disable the click in my case the hyperlinks.
Explanation using code example:
I want to disable this
PLAY
click, while interpreter is executing the below code:
var playGetReady = function (done) {
var ids = ['audiosource', 'a_5', 'a_4', 'a_3', 'a_2', 'a_1'],
playNext = function () {
var id = ids.shift();
document.getElementById(id).play();
if (ids.length) {
setTimeout(playNext, 1000);
} else {
done();
}
};
playNext();
};
Warning: This JS fiddle demo may play sound on load

You may try this (Changes in following function), but not sure if this is you want and maybe there are other ways to do it.
App.prototype.start = function () {
var self = this;
// unbind for a while
self.$button.unbind('click', self.buttonHandler); // <--
var start = function () {
// start countdown
self.intervalHandle = setInterval($.proxy(self.tick, self), 1000);
// bind again
self.$button.click($.proxy(self.buttonHandler, self)); // <--
// change button text to PAUSE
self.$button.text('PAUSE');
};
if (this.newTimer) {
playGetReady(start);
} else {
start();
}
};
DEMO.

In jquery, it can be done easily by cancel default action. Here's the sample.
$("#btn_start").click(function(event){
if(not_active_flag){
// Prevent anchor to active
return false;
}else{
// Anchor active as usual
return true;
}
});

In your case, the link will ultimately call this.buttonHandler, which has the following code:
App.prototype.buttonHandler = function (e) {
e.preventDefault(); // prevent anchor default action
this.toggle(); // toggle play/pause
};
Because buttonHandler is attached before playGetReady is executed, it is not possible to let playGetReady attach a click handler to that anchor element that uses .stopImmediatePropagation() to prevent the other click handler from executing.
In this case #gp.'s solution in the comments is most likely the best solution. In your case you might even be able to use a local variable in your app. If you use a global variable, reference it with window.yourglobalvariable. If you use a local variable, make sure you define it somewhere and reference it with this.yourvariable. Change your buttonHandler to:
App.prototype.buttonHandler = function (e) {
e.preventDefault(); // prevent anchor default action
if( this.soundready )
this.toggle(); // toggle play/pause
};
On the appropiate place make this variable false to prevent the 'button' from working. When the button should work, change the variable to true. I think that should be just before done() in the code you have in your question, but you probably have a better idea in what order the code is executed.

Modify target url in onclick handler

Is it possible to modify the target URL in the onclick handler? How?
I don't want to use things like window.location = ... because it changes the browsers' behaviour (click vs ctrl-click, opening in new tab, opening in particular window/frame etc...). I want a clean solution - just change the url and the rest should be done itself as it would normally be.
$(...).click(function () {
if (check_some_condition)
// modify target url here...
// do not want to do window.location= - this is not clean
// as it changes the browsers' behaviour (ctrl-click, opening in particular window/frame etc.)
return true;
});

Try
​$(function(){
$("#theLink").click(function(){
$(this).attr("href","http://tnbelt.com");
});
});​​​​

Edit: Updated code because the event handler script is executed first and then the default action takes place.
Added below version to show you that you can use .click as you didn't notice the quirks mode link I shared with you. DEMO
$(document).ready (function () {
$('#changeMe'). click (function (e) {
var goLucky = Math.floor(Math.random()*12);
if (goLucky % 2 == 0) {
this.href = "http://www.google.com";
} else {
this.href = "http://www.hotmail.com";
}
});
});
Commented e.preventDefault(); & $(this).click() as it is not required..
DEMO
$(document).ready (function () {
$('#changeMe').one ('click', function (e) {
//e.preventDefault();
this.href = "http://www.google.com";
//$(this).click();
});
});

Let us consider a hidden anchor tag
<a id="linkId" href="myPageToGo.html" class="thickbox" title="" style="visibility:hidden;">Link</a>
Then you can simulate the anchor click in your code...
$(...).click(function () {
if (check_some_condition)
$('#linkId').click();
return true;
});
EDIT - Alternative way
Wrap the element clicked inside a anchor tag...
$(...).click(function () {
if (check_some_condition)
$(this).wrap('<a id="new1" />');
$('#new1').click();
return true;
});

Yup.
$(this).attr('href', 'http://example.com/');

A lot of the answers including the top comment have missed out on an important point. If a user simply right clicks the URL to perhaps open in a new tab/window, this method won't work because you're directly requesting at the location specified by the 'href' URL instead of going through the onclick event.
You could try the same at this demo fiddle mentioned on Gourneau's post.
http://jsfiddle.net/skram/PtNfD/7/
$(document).ready (function () {
$('#changeMe').one ('click', function (e) {
this.href = "http://www.google.com";
});
});
