I have a function that dynamically creates links for a photo gallery. The function also produces a larger image as a background image of a div when and thumbnail is clicked on. What I want to do is have a third event, where if the user clicks the enlarged image in the div, the jQuery Fancybox loads an even bigger version of the image being displayed in the div. The problem is that the link for the anchor tag I'm using is created dynamically, and I know that Fancybox parses the HTML when the DOM is ready...unfortunately my function changes the DOM by appending the anchor tag for the full sized image. The help I need is using the Fancybox's options to specify the href attribute for the plugin. I'm sorry that was so long-winded...here's the code.
jQuery:
function gallery(picid, picnum){
var ext = 'jpg';
var fullSize = 'imgs/'+picid+'_full.'+ext;
$('#photolarge').css("background", 'url(imgs/'+picid+'_large.'+ext+') no-repeat');
$('#photolarge a').attr(
{ href: fullSize
//rel: 'lightbox',
}
);
$("#lightboxlink").click(function(){
$('#lightboxlink').fancybox({
'autoDimensions' : false,
'width' : 'auto',
'height' : 'auto',
'href' : fullSize
});
});
return false;
}
HTML Snippet
<div id="photolarge">
<a id="lightboxlink" href="#"></a>
</div>
<div id="phototable">
<ul id="photorow1">
<li><a onclick="gallery('bigsun',1)"><img id="sun" src="imgs/bigsun.jpg" /></a></li>
</ul>
</div>
CSS:
#photolarge {
width: 590px;
height: 400px;
margin-left: 7px;
border: 2px solid;
background: none;}
#phototable {
width: 590px;
height: 300px;
border: 2px solid;
margin: 10px 0 0 7px;}
#phototable img {
cursor: pointer;}
#phototable ul {
list-style: none;
display: inline;}
#phototable li {
padding-left: 10px;}
#lightboxlink {
display: block;
height: 100%;
width: 100%;}
Any help would be greatly appreciated!!!
Try this and see if it works,this is just fancy box bit though,the rest of your code seems fine
$("#lightboxlink").live('click', function(){
$.fancybox({
'autoDimensions' : false,
'width' : 'auto',
'height' : 'auto',
'href' : $(this).attr('href')
});
return false;
});

I want my app to have no title bar but still be closeable, draggable, minimizable, maximizable, and resizable like a regular window. I can do this in OS X since there is a [titleBarStyle] 1 option called hidden-inset that I can use but unfortunately, it's not available for Windows, which is the platform that I'm developing for. How would I go about doing something like this in Windows?
Above is an example of what I'm talking about.
Assuming you don't want window chrome, you can accomplish this by removing the frame around Electron and filling the rest in with html/css/js. I wrote an article that achieves what you are looking for on my blog here: http://mylifeforthecode.github.io/making-the-electron-shell-as-pretty-as-the-visual-studio-shell/. Code to get you started is also hosted here: https://github.com/srakowski/ElectronLikeVS
To summarize, you need to pass frame: false when you create the BrowserWindow:
mainWindow = new BrowserWindow({width: 800, height: 600, frame: false});
Then create and add control buttons for your title bar:
<div id="title-bar">
<div id="title">My Life For The Code</div>
<div id="title-bar-btns">
<button id="min-btn">-</button>
<button id="max-btn">+</button>
<button id="close-btn">x</button>
</div>
</div>
Bind in the max/min/close functions in js:
(function () {
var remote = require('remote');
var BrowserWindow = remote.require('browser-window');
function init() {
document.getElementById("min-btn").addEventListener("click", function (e) {
var window = BrowserWindow.getFocusedWindow();
window.minimize();
});
document.getElementById("max-btn").addEventListener("click", function (e) {
var window = BrowserWindow.getFocusedWindow();
window.maximize();
});
document.getElementById("close-btn").addEventListener("click", function (e) {
var window = BrowserWindow.getFocusedWindow();
window.close();
});
};
document.onreadystatechange = function () {
if (document.readyState == "complete") {
init();
}
};
})();
Styling the window can be tricky, but the key use to use special properties from webkit. Here is some minimal CSS:
body {
padding: 0px;
margin: 0px;
}
#title-bar {
-webkit-app-region: drag;
height: 24px;
background-color: darkviolet;
padding: none;
margin: 0px;
}
#title {
position: fixed;
top: 0px;
left: 6px;
}
#title-bar-btns {
-webkit-app-region: no-drag;
position: fixed;
top: 0px;
right: 6px;
}
Note that these are important:
-webkit-app-region: drag;
-webkit-app-region: no-drag;
-webkit-app-region: drag on your 'title bar' region will make it so that you can drag it around as is common with windows. The no-drag is applied to the buttons so that they do not cause dragging.
I was inspired by Shawn's article and apps like Hyper Terminal to figure out how to exactly replicate the Windows 10 style look as a seamless title bar, and wrote this tutorial (please note: as of 2022 this tutorial is somewhat outdated in terms of Electron).
It includes a fix for the resizing issue Shawn mentioned, and also switches between the maximise and restore buttons, even when e.g. the window is maximised by dragging the it to the top of the screen.
Quick reference
Title bar height: 32px
Title bar title font-size: 12px
Window control buttons: 46px wide, 32px high
Window control button assets from font Segoe MDL2 Assets (docs here), size: 10px
Minimise:
Maximise:
Restore:
Close:
Window control button colours: varies between UWP apps, but seems to be
Dark mode apps (white window controls): #FFF
Light mode apps (black window controls): #171717
Close button colours
Hover (:hover): background #E81123, colour #FFF
Pressed (:active): background #F1707A, colour #000 or #171717
Note: in the tutorial I have switched to PNG icons with different sizes for pixel-perfect scaling, but I leave the Segoe MDL2 Assets font characters above as an alternative
I use this in my apps:
const { remote } = require("electron");
var win = remote.BrowserWindow.getFocusedWindow();
var title = document.querySelector("title").innerHTML;
document.querySelector("#titleshown").innerHTML = title;
var minimize = document.querySelector("#minimize");
var maximize = document.querySelector("#maximize");
var quit = document.querySelector("#quit");
minimize.addEventListener("click", () => {
win.minimize();
});
maximize.addEventListener("click", () => {
win.setFullScreen(!win.isFullScreen());
});
quit.addEventListener("click", () => {
win.close();
});
nav {
display: block;
width: 100%;
height: 30px;
background-color: #333333;
-webkit-app-region: drag;
-webkit-user-select: none;
position: fixed;
z-index: 1;
}
nav #titleshown {
width: 30%;
height: 100%;
line-height: 30px;
color: #f7f7f7;
float: left;
padding: 0 0 0 1em;
}
nav #buttons {
float: right;
width: 150px;
height: 100%;
line-height: 30px;
background-color: #222222;
-webkit-app-region: no-drag;
}
nav #buttons #minimize,
nav #buttons #maximize,
nav #buttons #quit {
float: left;
height: 100%;
width: 33%;
text-align: center;
color: #f7f7f7;
cursor: default;
}
nav #buttons #minimize:hover {
background-color: #333333aa;
}
nav #buttons #maximize:hover {
background-color: #333333aa;
}
nav #buttons #quit:hover {
background-color: #ff0000dd;
}
main {
padding-top: 30px;
overflow: auto;
height: calc(100vh - 30px);
position: absolute;
top: 30px;
left: 0;
padding: 0;
width: 100%;
}
<html>

Ran into this problem and my solution was to keep the frame but set the title to blank i.e.
document.querySelector("title").innerHTML ="";
That solved my problem i.e. I got a window which can be closed, maximized or minimized without a title on it.
I'm trying to show a gif during an Ajax call; it works fine if the div is at the body level but won't appear in a tab panel. I've tried putting the div at the tab-pane, container, row and column levels but it won't show.
Simple html:
<div id="loading">
<img id="loading-image" src="images/page-loader.gif" alt="waiting..." />
</div>
jquery:
$('#loading').hide(); $('#loading').show(); // as required
css:
#loading {
width: 100%;
height: 100%;
top: 0px;
left: 0px;
position: fixed;
display: block;
opacity: 0.7;
background-color: #fff;
z-index: 99;
text-align: center;
}
#loading-image {
position: absolute;
top: 10px;
left: 24px;
z-index: 100;
}
Try this:
$(document).ajaxStart(function() {
$('<div id="loading"><img id="loading-image" src="images/page-loader.gif" alt="waiting..." /></img></div>')
.prependTo('.tabClass'); });
$(document).ajaxStop(function() {
$('#loading').remove();
});
replacing 'tabClass' with the class of whatever container you want the gif animation to attach to.
I've found this solution to be cleaner & work well.
I would like to achieve the effect where one image is revealed over the other when scrolling the page.
You can see an example on livearealabs.com (new york / seattle). Does anybody know how to create it using CSS3?
Check out this jsfiddle to create the sliding effect.
The trick is to have one div rotated 60 degrees. You position it so that it covers the entire wrapper and the overflow is hidden. Then with javascript you just have to move the slice container either by changing the left property or by changing the translate-X property.
Here is the code:
HTML:
<div class="wrapper">
<div class="bg"></div>
<div class="slice" data-show="true"></div>
</div>
CSS:
.wrapper {
position: relative;
overflow: hidden;
width: 20em;
height: 10em;
}
.bg {
background-color: red;
width: 100%;
height: 100%;
}
.slice {
position: absolute;
top: -12em;
left: -8em;
width: 30em;
height: 30em;
background-color: blue;
-webkit-transform: rotate(-60deg);
}
JS:
var hidden = false;
$('.wrapper').click(function() {
console.log('click');
if (hidden) {
$('.slice').stop().animate({left: '-8em'}, 2000);
hidden = false;
} else {
$('.slice').stop().animate({left: '-34em'}, 2000);
hidden = true;
}
console.log('click end');
});
Also check out this jsfiddle for a similar sliding effect that can be achieved with CSS only.
After learning JS for about a month now and completing around 4 courses I am still unable to work out how to change an image when clicking a thumbnail! What I want to do is simple, I just want to change the Main Image when a thumbnail is clicked! In this example there are two thumbnail images in a div and a main image above them. I just want to change the main image when a thumbnail is clicked. I know this is DOM Manipulation and think it is: document.getElementById.....?
I have make a small page so that I can learn / try different things and and finally giving up and asking for help! The code is as follows:
#MainContainer {
position: relative;
margin:0px auto;
width: 500px;
height: 400px;
border: 1px solid black;
}
#MainImage {
position: absolute;
top: 10px;
left: 50px;
width: 398px;
height: 265px;
background: url(MainImage01.jpg);
border: 1px solid black;
}
#TNBodyContainer {
position: absolute;
top: 290px;
left: 100px;
border: 1px solid black;
width: 268px;
height: 88px;
}
#TNOne {
position: relative;
width: 133px;
height: 88px;
background: url(SmallImage01.jpg);
}
#TNTwo {
position: relative;
left:135px;
width: 133px;
height: 88px;
background: url(SmallImage02.jpg);
}
<body>
<div id="MainContainer">
<div id="MainImage"></div>
<div id="TNBodyContainer">
<div id="TNOne">
<div id="TNTwo"></div>
</div>
</div>
Thank you very much for any help.

You need to add some scripting to change the image when either of the thumbnails are clicked. This function is called when the page is loaded. Change the image names to suit.
This should be placed in the section of the html page.
<script>
window.onload = function() {
var mainImg = document.getElementById('Main');
document.getElementById('TNOne').onclick = function() {
mainImg.src = 'main1.jpg';
//alert('one clicked');
};
document.getElementById('TNTwo').onclick = function() {
mainImg.src = 'main2.jpg';
//alert('two clicked');
};
};
</script>
The two thumbnail divs become <img> tags with the same IDs.
Similarly the main <img> is defined also (with id="Main"). Now the elements
are clickable.
<div id="MainContainer">
<div id="MainImage">
<img id="Main" src="MainImage01.jpg"</img>
</div>
<div id="TNBodyContainer">
<img id="TNOne" src="thumb1.jpg"></img>
<img id="TNTwo" src="thumb2.jpg"></img>
</div>
</div>
Finally CSS for the thumbnails, here float is used to keep the thumbnails in the same line within the TNBodyContainer div.
TNOne {
width: 133px;
height: 88px;
float:left;
}
#TNTwo {
width: 133px;
height: 88px;
float:left;
}
To change the image in the CSS background property, you need to use
document.getElementById("MainImage").style.background
The right way to go is to add event listeners:
document.getElementById("TNOne").addEventListener("click", function (event) {
setImage(event);
}, false);
document.getElementById("TNTwo").addEventListener("click", function (event) {
setImage(event);
}, false);
}
They both call the same function, but with event it is possible to see which one "clicked" with "event.target.id".
You can then decide what you want to do with for instance a switch statement. basically saying: if event.target.id == "TNOne".
You can see all this I made you a fiddle: http://jsfiddle.net/djwave28/32pQD/3/
There are some slight changes in your HTML and CSS too.
I want to create a thumbnail from an image uploaded from user on webpage. I want to create a image gallery where i can show all images preview as thumbnail and when user clicks he can see enlarged image.
Is it possible to do this so that page dont get heavy
You should probably cache the thumbnail images, but to create them see:
What is the "best" way to create a thumbnail using ASP.NET?
You must set a class for image tags for thumbnail. such this :
.thumbnail {
box-shadow: 0 0 7px #fff;
cursor: pointer;
float: left;
height: 70px;
margin-bottom: 10px;
margin-top: -35px;
width: 70px;
border: 3px solid #ff``f;
border-radius: 3px;
}
and so for example :
<img id="Image1" class="thumbnail" src="..." .../>
and all images resize with css. and for create enlarged image you must use jquery Modal. for Modal read this link : http://www.jacklmoore.com/colorbox/
you must create a jquery file. after click on each image you must call plugin with your src. such this jquery:
$('.thumbnail').on('click', function () {
var src = $(this).attr('src');
$(this).colorbox({ html: "<img src='" + src + "' style='width:1024px;height:728px'/>", width: "1024px", height: "728px", close: "", closeButton: true, scrolling: false, overlayClose: true, scalePhotos: true, escKey: true });
});
