Image Overlay jQuery - Get Image to Stay on Click - javascript

I am using the following code to display an overlay image when the base-image is hovered over:
$(".roll").css("opacity","0");
$(".roll").show();
// on mouseover
$(".roll").hover(function () {
var s = $(this).siblings('img');
var w = s.css("width");
var h = s.css("height");
$(this).css("height",h).css("width",w).stop().animate({
opacity: .6 },
"fast");
},
// on mouseout
function () {
$(this).stop().animate({
opacity: 0
}, "fast");
});
This is what the HTML looks like:
<a class="image" href="#">
<span class="roll" style="display:none;"></span>
<img src="mypic.png" class="image">
</a>
How do I implement an "on click" event, so that when the image is clicked, the overlay remains instead of disappearing upon mouseout.
I've gotten started with the following, but not sure what else to do:
$('.roll').on("click", function() {
if ($(this).hasClass("selected")) {
$(this).removeClass("selected");
// remove overlay here?
}
else if (!$(this).hasClass("selected")) {
$(this).addClass("selected");
// add overlay here?
}
});
Probably easy, but I'm not sure how to carry it out beyond the basic mouseover/mouseout.
Thanks!

you can prevent on mouse out function when img has not class selected like
//on mouseout
function () {
if (!$(this).hasClass("selected"))
{
$(this).stop().animate({
opacity: 0
});
}
}
Means you have to check in mouseover/out function that: your images has already clicked or not?
Onmouseover:if not already clicked(Selected) then add overlay
Onmouseout: if not already clicked(Selected) then remove overlay

Do you want the overlay image to receive the click event, or the base image? I'm going to assume the base image, but the implementation should be basically the same.
// declare a flag in the outer scope
var stickImage = false;
$(".roll").css("opacity", "0");
$(".roll").show();
// on mouseover
$(".roll").hover(function() {
var s = $(this).siblings('img');
var w = s.css("width");
var h = s.css("height");
$(this).css("height", h).css("width", w).stop().animate({
opacity: .6
}, "fast");
});
// on click, toggle the stickImage boolean
$(".roll").click(function() {
stickImage = !stickImage;
});
// on mouseout
function() {
// check to make sure stickimage is false before hiding
if (!stickImage) {
$(this).stop().animate({
opacity: 0
}, "fast");
}
});

Creating my custom tooltip using jquery plugin

Using jquery plugin with mouse hide and show I am trying to create tool tip.I am facing two problem
Whether my code is correct for mouseout and mouseleave
When I am creating lot of tooltip it was not positioning correctly it was coming down actually it has to come to right side.
I have found so many from stack Overflow but nothing is working out.
Here is the jquery code
$(document).ready(function() {
$(".tooltip").hide();
$("#help").on({
mouseenter: function () {
$("#showtooltip").show();
},
mouseleave: function () {
$("#showtooltip").hide();
}
});
$("#help1").on({
mouseenter: function () {
$("#showtooltip1").show();
},
mouseleave: function () {
$("#showtooltip1").hide();
}
});
$("#help2").on({
mouseenter: function () {
$("#showtooltip2").show();
},
mouseleave: function () {
$("#showtooltip2").hide();
}
});
});
Third mouse over was not working. I am trying to creating I think missed something.
Here is the jsbin Link
Kindly help me
Thanks & Regards

Just add this css rules to your .tooltip class:
position: absolute;
top: 40px; /* define how much space from tooltip to the top
and this javascript:
$(document).ready(function() {
$(".tooltip").hide();
$("#help").on({
mouseenter: function (e) {
$("#showtooltip").show();
$("#showtooltip").css('left', e.pageX); // added
},
mouseleave: function () {
$("#showtooltip").hide();
}
});
$("#help1").on({
mouseenter: function (e) {
$("#showtooltip1").show();
$("#showtooltip1").css('left', e.pageX); // added
},
mouseleave: function () {
$("#showtooltip1").hide();
}
});
$("#help2").on({
mouseenter: function (e) {
$("#showtooltip2").show();
$("#showtooltip2").css('left', e.pageX); // added
},
mouseleave: function () {
$("#showtooltip2").hide();
}
});
});
I added only this line in javascript mouseenter function:
$("#showtooltip").css('left', e.pageX);
It sets the tooltip left coordinate, in case you have many items, the tooltip will show exactly beneath the hovered item.
Customization
If you want the tooltip right of the hovered item, you will need to add this css:
var rightMargin = 20; // or whatever fits your needs
$("#showtooltip").css('left', e.pageX + rightMargin);
and change your css top property above.
Update
Since this code of yours is very coupled and you asked for a better solution, here it is jQuery code:
$(document).ready(function() {
$(".tooltip").hide();
$(".help").on({
mouseenter: function (e) {
var tooltip = $(this).next(); tooltip.show();
tooltip.css('left', e.pageX + 20);
},
mouseleave: function () {
$(this).next().hide();
}
});
});
to work this, you gonna have to remove your coupled ids and instead add to every anchor tag class help.
the code simply checks if the user is hovering a link, and if so, then just show the next element after it, which happens to be the tooltip.
Here is a FIDDLE

skip visible items from animating using JS

I'm using waypoints to have fadeIn animation when the user scrolled down, and it worked. But as you can see, during the onload, there's a fadeIn too for the first few visible items.
How to not to have that? since I binded all .card to way[point.
My js
$(function() {
var waypoints = $('.card').waypoint(function (direction) {
$(this).addClass("animated fadeIn");
}, {
offset: '90%'
});
});
DEMO : http://jsfiddle.net/ghx49d7x/
Not sure if its exactly what you want, but you can add a variable to indicate if the page has loaded or not and only add fadeIn if it has:
$(function () {
var pageLoaded = false;
var waypoints = $('.card').waypoint(function (direction) {
$(this).addClass("animated"
+ (pageLoaded ? " fadeIn" : ""));
}, {
offset: '90%'
});
pageLoaded = true;
});

how do I stop the query animation que when a nav button is clicked

What I want: I created a sort of image gallery with a thumbnail slider and I want the thumbnails to scroll when a nav button is clicked but if the button is pushed again before the animation is completed it doesn't keep adding to the que, it clears the que and only completes the current animation.
What my problem is: When the button is clicked it puts the click animation in a que and completes all the clicks in order. Maybe someone can help we word this better.
What I have tried: I have tried adding .finish() and .stop(true, true) to my js file but I can't seem to get it working right. I'm probably putting it in the wrong spot or even using the wrong thing, I don't know and so I need some help.
Here is a functioning jsfiddle: http://jsfiddle.net/ma9j6o09/2/
Some of it is not working since my images are locally hosted but the slider part for the thumbnails is.
This is my function for animating the movement; what do I add to get the effect I need?
var clicks = 0;
$("#right").click(function() {
if ( clicks < 5 ) {
clicks++;
$("#thumbContainer").animate({
left: "-=128px"
}, 500, function() {
// Animation complete.
});
}
});
$("#left").click(function() {
if (clicks > 0) {
clicks--;
$("#thumbContainer").animate({
left: "+=128px"
}, 500, function() {
// Animation complete.
});
}
});
Try this out: http://jsfiddle.net/ma9j6o09/3/
In response to your question about .stop() you would use it like this:
$("#thumbContainer").stop(true, true).animate({
left: "+=128px"
}, 500, function() {
// Animation complete.
});
});
But this will indeed not achieve what you want as it means it will stop the animation and jump to the last frame straight away so you lose the animation you wanted.
Instead use the flag I used in the fiddle which makes it impossible to even try animate whilst an animation is in progress.
var clicks = 0,
animating = false;
$("#right").click(function() {
// Only animate if we are not already animating
if ( clicks < 5 && !animating ) {
animating = true;
clicks++;
$("#thumbContainer").animate({
left: "-=128px"
}, 500, function() {
animating = false; // No longer animating
// Animation complete.
});
}
});
$("#left").click(function() {
// Only animate if we are not already animating
if (clicks > 0 && !animating) {
animating = true;
clicks--;
$("#thumbContainer").animate({
left: "+=128px"
}, 500, function() {
animating = false; // No longer animating
// Animation complete.
});
}
});

Delay animation until other animation is complete (sliding content(

I have this code which animates between divs sliding out. If an item is clicked, it's relevant content slides out. If another item is clicked, the current content slides back in and the new content slides out.
However,
var lastClicked = null;
var animateClasses = ['ale', 'bramling', 'bullet', 'miami-weisse'];
for (var i=0; i<animateClasses.length; i++) {
(function(animCls) {
$('.each-brew.'+animCls).toggle(function() {
if (lastClicked && lastClicked != this) {
// animate it back
$(lastClicked).trigger('click');
}
lastClicked = this;
$('.each-brew-content.'+animCls).show().animate({ left: '0' }, 1000).css('position','inherit');
}, function() {
$('.each-brew-content.'+animCls)
.animate({ left: '-33.3333%' }, 1000, function() { $(this).hide()}) // hide the element in the animation on-complete callback
.css('position','relative');
});
})(animateClasses[i]); // self calling anonymous function
}
However, the content sliding out once the already open content slides back is sliding out too quickly - it needs to wait until the content has fully slided back in before it slides out. Is this possible?
Here's a link to what I'm currently working on to get an idea (http://goo.gl/s8Tl6).
Cheers in advance,

Here's my take on it as a drop-in replacement with no markup changes. You want one of three things to happen when a menu item is clicked:
if the clicked item is currently showing, hide it
if something else is showing, hide it, then show the current item's content
if nothing is showing, show the current item's content
var lastClicked = null;
// here lastClicked points to the currently visible content
var animateClasses = ['ale', 'bramling', 'bullet', 'miami-weisse'];
for (var i=0; i<animateClasses.length; i++) {
(function(animCls) {
$('.each-brew.'+animCls).click(function(event){
if(lastClicked && lastClicked == animCls){
// if the lastClicked is `this` then just hide the content
$('.each-brew-content.'+animCls).animate(
{ left: '-33.3333%' }, 1000,
function() {
$(this).hide();
}).css('position','relative');
lastClicked = null;
}else{
if(lastClicked){
// if something else is lastClicked, hide it,
//then trigger a click on the new target
$('.each-brew-content.'+lastClicked).animate(
{ left: '-33.3333%' }, 1000,
function() {
$(this).hide();
$(event.target).trigger('click');
}).css('position','relative');
lastClicked = null;
}else{
// if there is no currently visible div,
// show our content
$('.each-brew-content.'+animCls).show()
.animate({ left: '0' }, 1000)
.css('position','relative');
lastClicked = animCls;
}
}
});
})(animateClasses[i]); // self calling anonymous function
}
Well, I'm pretty sure there are other more easy possibilities and I didn't have much time but here is a working jsfiddle: http://jsfiddle.net/uaNKz/
Basicly you use the callback function to wait until the animation is complete. In this special case it's the complete: function(){...}
$("document").ready(function(){
$('#ale').click(function(){
if ($('div').hasClass('toggled')){
$('.toggled').animate({ width: "toggle" }, { duration:250, complete: function(){
$('#alecont').animate({ width: "toggle" }, { duration:250 }).addClass('toggled');}
}).removeClass('toggled');
}else{
$('#alecont').animate({ width: "toggle" }, { duration:250 }).addClass('toggled');
}
});
$('#bramling').click(function(){
if ($('div').hasClass('toggled')){
$('.toggled').animate({ width: "toggle" }, { duration:250, complete: function(){
$('#bramcont').animate({ width: "toggle" }, { duration:250 }).addClass('toggled');}
}).removeClass('toggled');
}else{
$('#bramcont').animate({ width: "toggle" }, { duration:250 }).addClass('toggled');
}
});
});
I give a toggled class if a div is expanded. Since the animation on your page seems to be pretty much broken I think this would be a better way to do this. But remember: my code isn't really good. Just fast and it can be refactored. It's working tho..
Rather than using toggles, bind an on "click" handler to your ".each-brew" divs. In the handler, first hide content divs and then show the appropriate content when that animation completes. You can do that with either a promise or a callback. Something like this...
$(".each-brew").on("click", function (event) {
$(".each-brew-content").show().animate({ left: "0" }, 1000, function() {
// Get the brew name from the class list.
// This assumes that the brew is the second class in the list, as in your markup.
var brew = event.currentTarget.className.split(/\s+/)[1];
$(".each-brew-content." + brew).animate({ left: "-33.3333%" }, 1000, function() { $(this).hide(); });
});
});
I think an event and observer would do the trick for you.
set up the callback function on completion of your animation to fire an event.
the listener would first listen for any animation event and after that event is triggered listen for the completion event. when the completion event is fired execute the initial animation event.run method (or whatever you would want to call it)
Within the listener
on newanimationeventtriger(new_anim) wait for x seconds (to eliminate infinite loop poss) while if this lastevent triggers done == true{
new_anim.run();
}

Make div open with your mouse and not click

I have make this: This In the right you see a red button. When you click on the red button. The content screen with the text is coming. But i have a question of this. Can i make this with a other animation. If you hold your mouse. Then you can slide open. With your mouse button to left. Then the content box open. Do you understand it? I hope you can help me.
You can see the code on jsfiddle. And you can change it there. I hope you can help me. I am a starting javascripter. And how And have no idea how I can make this.
To implement dragging, you can make use of mousedown/mouseup/mousemove like this: http://jsfiddle.net/pimvdb/25y4K/8/.
$(function () {
"use strict";
var box = $(".what-is-delicious"),
button = $(".what-is-delicious > a");
var mouseDown = false,
grabbed = 0,
start = -303;
button.mousedown(function(e) {
mouseDown = true;
$('*').bind('selectstart', false); // prevent selections when dragging
grabbed = e.pageX; // save where you grabbed
$("body").append('<div class="background-overlay"></div>');
});
$('body').mouseup(function() {
mouseDown = false;
$('*').unbind('selectstart', false); // allow selections again
$(".background-overlay").remove();
start = parseInt(box.css('right'), 10); // save start for next time
// (parseInt to remove 'px')
}).mousemove(function (e) {
if(mouseDown) { // only if you are dragging
// set right to grabbed - pageX (difference) + start 'right' when started
// dragging. And if you drag too far, set it to 0.
box.css("right", Math.min(grabbed - e.pageX + start, 0));
}
});
});
Here is an updated fiddle. Basically I just did a couple of things:
Changed the handler from "click" to "mouseenter"
Added a "mouseleave" handler that does the opposite thing
Put the handlers on the "what-is-delicious" container instead of the <a>
The code:
$(function () {
"use strict"
var box = $(".what-is-delicious"),
button = $(".what-is-delicious > a");
box.mouseenter(function (e) {
e.preventDefault();
if ($(button).hasClass("open")) {
} else {
$("body").append('<div class="background-overlay"></div>');
button.addClass("open");
box.animate({ right: "0"}, 750);
}
}).mouseleave(function (e) {
e.preventDefault();
if ($(button).hasClass("open")) {
$("body").find('div.background-overlay').remove();
button.removeClass("open");
box.animate({ right: -303}, 750);
} else {
}
});
});
The "preventDefault()" calls aren't really necessary anymore but I left them there.
I would assume you are toggling the Style.Display of the DIV currently in an OnClick() event.
The same code can be called from a Hover() or MouseOver()
