Make a sticky scrollable sidebar with no styles applied through JS

Make a sticky scrollable sidebar with no styles applied through JS - javascript

That's how it should work. I saw this sidebar some time ago and was able to find the page in the web archive.
When you scroll down the page, the sidebar scrolls too and sticks to the bottom. When you scroll up, even if you're somewhere in the middle of the page, the sidebar scrolls up too.
This solution is fairly simple and doesn't apply any CSS while the sidebar is working. Some kind of magic using initial CSS like full viewport height, sticky positioning, hidden overflow and JS like scrollTop.
I managed to pull out the part of the source code that's responsible for the sidebar, but I can't understand how it works. This function seems to be responsible for such behavior:
function(e, t) {
Air.define(
'module.sticky_sidebar',
'lib.DOM, module.DOM, module.metrics, module.propaganda, module.notify, module.smart_ajax',
function(e, t, n, i, o, r) {
var a,
s,
l,
c = this,
u = 0,
d = !1,
h = function() {
var t = s.scrollTop,
i = Math.round(e.rect(a).top)
50 === i
? (s.scrollTop = t + (n.scroll_top - u))
: i > 50
? (s.scrollTop = 0)
: i < 50 && (s.scrollTop = 999999),
(u = n.scroll_top)
},
f = function() {
a && s && e.bem.toggle(a, 'height_auto', !(n.window_height - 50 < s.scrollHeight))
},
m = function(t) {
if (((5 != t && 3 != t) || (l[t] = !1), !1 === l[5] && !1 === l[3])) {
var n = e.find('.page--entry')
n && (e.toggleClass(n, 'with--entry_center', !0), c.destroy()), (n = null)
}
}
;(c.init = function() {
;(a = c.elements[0].element),
(s = e.find(a, '.sticky_sidebar__scroll')),
(l = {
5: !0,
3: !0
}),
n.on('Breakpoint changed', function(e) {
'wide' === e || 'desktop' === e
? !1 === d &&
n.document_height - 20 > n.window_height &&
(t.on('Window scroll', h), t.on('Window resize', f), f(), (d = !0))
: !0 === d && (t.off(), (d = !1))
})
}),
(c.refresh = function() {
c.destroy(), c.init()
}),
(c.destroy = function() {
t.off(), n.off(), i.off(), (u = 0), (a = s = null), (d = !1)
})
}
)
}
And the CSS:
.sticky_sidebar {
top: 50px;
height: calc(100vh - 50px);
width: 300px;
margin-top: -20px;
position: sticky;
}
.sticky_sidebar__scroll {
width: 100%;
height: 100%;
overflow: hidden;
}
Can someone explain how this works?

Mouseleave delay

I'd like to delay the zoomed image disappearing by a X seconds so I can fade out the image rather than it simply disappearing.
Can I simply add .delay(1000) somewhere to the mouseleave / hide lines of code?
I've tried that but unfortunately doesn't seem to work. I've also tried to wrap a setTimeout( ... , 1000); around various parts of the code, but couldn't make that work either.
Any help much appreciated!
Here is the Jsfiddle https://jsfiddle.net/mr_antlers/nh5jw5tb/2/

You can pass in beforeShow and beforeHide argument into easyZoom when you instantiate them.
var $easyzoom = $('.easyzoom').easyZoom({
beforeHide: function() {
this.$flyout.fadeOut();
return false;
},
beforeShow: function() {
this.$flyout.show();
}
});

You can refer the flyout zoomed image using this.$flyout in the functions.
Return false if you want to stop the default hide or show function. Just remember to add the default behavior into your function if you are doing that.
In the example I did above, I do a fadeOut on the zoomed image and stop the flyout from detaching (default behavior is detach() the zoomed image element). Then, as the flyout element was faded out, I have to use $.show() or the element will be stuck at display: none and nothing will be shown on mouseover.
Hope this helps.

'mouseleave' trigger _onLeave() which fire hide() which cause the zoomed div with image is removed from the DOM so any CSS transition or $().fadeOut() does not work. I removed hide() firing when mouseleave and change opacity in CSS and it seems to work now and anything else seems to be broken. Change opacity time as you wish.

How to scroll down to content box in this video style with jquery/javascript?

I have a page with video styles - http://picovico.com/video-styles/ in my WordPress. Everything is working fine, except that I would like to scroll down to content when the thumbnails are clicked. Right now the content box is opening but the window is not scrolling down to it. Actually I am using a plugin called expand grid. I am not getting support from the plugin author.
I am using bellow code:
$(".cq-expandgrid-item").click(function() {
$('html, body').animate({
scrollTop: $(".cq-expandgrid-content").offset().top
}, 5000);
});
Thanks.
#TTCC Here's the init.min.js present in the plugin file. The code is given below. With your help, I hope I can locate and add the code you suggested now:
jQuery(document).ready(function(a) {
a(".cq-expandgrid").each(function(b, c) {
function r() {
o = setInterval(function() {
clearInterval(o), k++, k > m && (k = 0), a(".cq-expandgrid-toggle", p).eq(k).trigger("click"), r()
}, 1e3 * j)
}
var d = a(this),
e = a(this).data("itemsize"),
f = "yes" == a(this).data("transparentitem") ? !0 : !1,
g = a(this).data("labelfontsize"),
h = a(this).data("subfontsize"),
i = parseInt(a(this).data("itemheight"), 10),
j = parseInt(a(this).data("autoslide"), 10),
k = 0,
m = a(".cq-expandgrid-item", d).length,
n = "yes" == a(this).data("openfirst") ? !1 : !0,
o = 0,
p = a(".cq-expandgrid-item", d).each(function(b) {
a(this).data("index", b);
var c = a(this).data("image"),
d = a(this).data("avatar"),
f = a(this).data("backgroundcolor"),
j = a(this).data("iconcolor"),
k = a(this).data("iconsize"),
l = a(this).data("contentcolor"),
m = a(this).data("labelcolor"),
n = a(this).data("subtitlecolor"),
o = a(this).data("bgstyle"),
p = a(this).data("avatartype"),
q = a(this),
r = a(this).attr("title");
if (r && "" !== r) var r = a(".cq-expandgrid-face", q).tooltipster({
content: r,

});
"" != l && a(".cq-expandgrid-text, .cq-expandgrid-text p, .cq-expandgrid-text h2, .cq-expandgrid-text h3, .cq-expandgrid-text h4, .cq-expandgrid-text h5, .cq-expandgrid-text h6", q).css("color", l), "" != m && a(".cq-expandgrid-title", q).css("color", m), "" != n && a(".cq-expandgrid-subtitle", q).css("color", n), "" != g && a(".cq-expandgrid-title", q).css("font-size", g), "" != h && a(".cq-expandgrid-subtitle", q).css("font-size", h), i > 0 && "customized" == e && a(".cq-expandgrid-face", q).css("height", i), "" != f && "customized" == o && a(".cq-expandgrid-face", q).css("background-color", f), "" != j && a(".cq-expandgrid-icon", q).css("color", j), "" != k && a(".cq-expandgrid-icon", q).css("font-size", k), "" != c && "undefined" != c && c && a(".cq-expandgrid-face", q).css({

}), "image" == p && "" != d && "undefined" != d && d && a(".cq-expandgrid-avatar", q).css({
"background-image": "url(" + d + ")"
})
}),
q = null;
d.on("mouseover", function(a) {
clearInterval(o)
}).on("mouseleave", function(a) {
j > 0 && r()
}), a(".cq-expandgrid-toggle", p).click(function() {
var b = a(this).closest(".cq-expandgrid-item");
b.data("backgroundcolor");
if (k = b.data("index"), clearInterval(o), q && !b.is(q)) {
q.removeClass("cq-expandgrid-openstate").addClass("cq-expandgrid-initstate"), f && p.removeClass("outfoucs");
var d = a("iframe", q).attr("src");
d && "" != d && (d.indexOf("youtube") > -1 || d.indexOf("vimeo") > -1) && (a("iframe", q).attr("src", ""), a("iframe", q).attr("src", d))
}
b.hasClass("cq-expandgrid-initstate") ? (q = b.removeClass("cq-expandgrid-initstate").addClass("cq-expandgrid-openstate"), p.not(b).hasClass("outfoucs") || f && p.not(b).addClass("outfoucs")) : (b.removeClass("cq-expandgrid-openstate").addClass("cq-expandgrid-initstate"), f && p.not(b).removeClass("outfoucs"))
}), (n || j > 0) && a(".cq-expandgrid-toggle", p).eq(0).trigger("click"), j > 0 && r(), p.find(".cq-expandgrid-close").click(function() {
var b = a(this).closest(".cq-expandgrid-item");
b.removeClass("cq-expandgrid-openstate").addClass("cq-expandgrid-initstate"), p.not(b).removeClass("outfoucs")
})
})
});
#TTCC, Here's the code I implemented as per your suggestion:
b.hasClass("cq-expandgrid-initstate") ? (q = b.removeClass("cq-expandgrid-initstate").addClass("cq-expandgrid-openstate"), p.not(b).hasClass("outfoucs") || f && p.not(b).addClass("outfoucs")) : (b.removeClass("cq-expandgrid-openstate").addClass("cq-expandgrid-initstate"), f && p.not(b).removeClass("outfoucs")), b.hasClass("cq-expandgrid-initstate") && a('body').stop().animate({scrollTop: b.find(".cq-expandgrid-content").offset().top - 50 }, 500);
})

Your javascript code has two script tag in your page, and this error make code can not run.
Actually, you don't need to write a piece of code alone, and just move it to the "cq-expandgrid-toggle" click event in vc-extensions-expandgrid/js/init.min.js" file.
You can use jQuery.animate() and scrollTop property to achieve it.
Replace code in init.min.js file from line 63 to 65 (before "})") by my code below:
b.hasClass("cq-expandgrid-initstate") ? (a('body').stop().animate({scrollTop: b.find(".cq-expandgrid-content").offset().top - 0}, 200),q = b.removeClass("cq-expandgrid-initstate").addClass("cq-expandgrid-openstate"), p.not(b).hasClass("outfoucs") || f && p.not(b).addClass("outfoucs"))
: (b.removeClass("cq-expandgrid-openstate").addClass("cq-expandgrid-initstate"), f && p.not(b).removeClass("outfoucs"));
"500" is a number determining in millisecond how long the animation will run, and you can change it as your wish.
And remove transition style of .cq-expandgrid-content in /wp-content/plugins/vc-extensions-expandgrid/css/style.css file (about line 378).
transition: all 0.2s ease-in-out;
Here is a jsfiddle.

Try like this:
$(".cq-expandgrid-item").click(function() {
var $this = $(this);
$('html, body').animate({
scrollTop: $this.find(".cq-expandgrid-content").offset().top
}, 5000);
});
PD: with $(".cq-expandgrid-content").offset().top you where trying get multiple values, because there are many .cq-expandgrid-content" occurrences

How does Twitter implement its Tweet Box?

I'm trying to implement something like Twitter's tweet box, specifically:
Automatically highlights text in a red background when the overall length exceeds 140 characters.
Automatically highlights links, mentions, and hashtags in blue.
These should happen automatically aka when a user types.
By the semantic markup I'm seeing on Twitter, it looks like they're using a contentEditable div. And the DOM inside is modified whenever a mention/hashtag/link is detected, or when the length is exceeded over 140 characters:
<div aria-labelledby="tweet-box-mini-home-profile-label" id="tweet-box-mini-home-profile" class="tweet-box rich-editor notie" contenteditable="true" spellcheck="true" role="textbox" aria-multiline="true" dir="ltr" aria-autocomplete="list" aria-expanded="false" aria-owns="typeahead-dropdown-6">
<div>hello world <a class="twitter-atreply pretty-link" href="/testMention" role="presentation"><s>#</s>testMention</a> text <s>#</s>helloWorld text http://www.google.com text text text text text text text text text text text text text text <em>overflow red text here</em>
</div>
</div>
What I have done so far
Currently, I'm using a contentEditable field. It triggers a function onChange/onInput that parses the text. Check if it has a username/link/hashtag via regexr and replace them with the respective tags (I'm just using a simple <i> tag to enclose username and hashtag for now).
The problem I'm having is that because I'm changing/modifying the DOM of the contentEditable, the caret cursor position becomes lost.
I looked at this thread Persisting the changes of range objects after selection in HTML and it works fine only if the DOM isn't changed (which it is in my case, surrounding tags/hashtags with <i> tags, links with <a> tags, and overflow with <b> tags.
Fiddle: http://jsfiddle.net/4Lsqjkjb/
Does anyone have any alternative solutions/approaches on how to tackle this problem? Maybe I shouldn't use contentEditable? Or some way that doesn't directly modify the DOM of the contentEditable field so the caret position is maintained? Any help would be appreciated! I tried playing around with window.getSelection() and saving it before DOM change, but it always seem to reset after DOM changes are applied.

What I did is kind of a hack but works quite well as a workaround solution.
I've got a simple textarea (not contenteditable because of what's next, I'll explain below) and a div which is absolute positioned behind the textarea. Using javascript, I copy the content from the textarea to the div while splitting it at 140 chars and putting all extra characters inside an <em /> tag.
Well, it's a little bit more complicated because twitter algorithm to compute a tweet length is different (links doesn't count as their real value, because of t.co url shortening). The exact method can be found as part of the official twitter/twitter-txt repository.
Step-by-step code.
Wrap a simple textarea into a div to simplify the css:
<div class="tweet-composer">
<textarea class="editor-textarea js-keeper-editor">This is some text that will be highlight when longer than 20 characters. Like twitter. Type something...</textarea>
<div class="js-keeper-placeholder-back"></div>
</div>
CSS is just making the textarea and the div right above each other and highlight the text.
.tweet-composer {
position: relative;
z-index: 1;
}
.js-keeper-editor,
.js-keeper-placeholder-back {
background: transparent;
border: 1px solid #eee;
font-family: Helvetica, Arial, sans-serif;
font-size: 14px; /* Same font for both. */
margin: auto;
min-height: 200px;
outline: none;
padding: 10px;
width: 100%;
}
.js-keeper-placeholder-back {
bottom: 0;
color: transparent;
left: 0;
position: absolute;
top: 0;
white-space: pre-wrap;
width: 100%;
word-wrap: break-word;
z-index: -1;
}
.js-keeper-placeholder-back em {
background: #fcc !important;
}
Now the fun part, this is implemented using jQuery but that's not the important thing.
if (0 > remainingLength) {
// Split value if greater than
var allowedValuePart = currentValue.slice(0, realLength),
refusedValuePart = currentValue.slice(realLength)
;
// Fill the hidden div.
$placeholderBacker.html(allowedValuePart + '<em>' + refusedValuePart + '</em>');
} else {
$placeholderBacker.html('');
}
Add some event handler on change, and te common document ready and you're done. See the codepen link below.
Note that the div placed behind can be created using js too, when loading the page:
// Create a pseudo-element that will be hidden behind the placeholder.
var $placeholderBacker = $('<div class="js-keeper-placeholder-back"></div>');
$placeholderBacker.insertAfter($textarea);

This is not a direct answer with source code building the part of your application to your spec.
This is really not an easy thing to do.
You're right - the way to solving this problem is to use a contenteditable="true" container. But I'm afraid that from there it gets much much more complicated.
Enter DraftJS - A javascript solution to rich-text editing which does most of the heavy lifting for you.
Both of my solutions below require the use of both React and DraftJS
The Plug-&-Play Solution:
The React + DraftJS + Someone Else's "Plugin" solution is already here. You can check out draft-js-plugins.com. And here's the Github source code.
Personally, I wouldn't go this way. I would rather study their GitHub source code and implement my own DraftJS entities. Because I think that React-JS-Plugins feels a little bit clunky and overweight for just Links and Mentions. Plus, where are you "mentioning" from? Your own Application? Twitter? Doing it this way lets you have control over where you're grabbing the so-called "mentions".
The DIY Solution:
The best way I have found is to build your own set of working entities on top of a DraftJS based rich-text editor.
This of course also requires that you're using React.
Forgive me for not actually building a complete set of working code. I was interested in doing something similar for an App I'm building in Meteor with React on the front-end. So this really made sense to me because I'd only be adding one more library (DraftJS) and the rest would be my custom entities coded out.

Turns out this is really not an easy thing to do. I've been struggling with it for the past few days, and I'm not very close to a solution.
Your best drop-in solution currently is the At.js library, which is still being maintained, but definitely isn't perfect. One of the examples shows how you can kind of do a text highlight.
The most annoying part of this problem is that Twitter has a beautiful solution that seemingly works perfectly staring us right in the face. I took some time investigating the way they implement their "tweet box," and it's definitely not trivial. It looks like they're doing almost everything manually, including emulating undo/redo functionality, intercepting copy/pastes, providing custom code for IE/W3C, custom-coding Mac/PC, and more. They use a contenteditable div, which is in-and-of-itself problematic due to differences in browser implementations. It's pretty impressive, actually.
Here's the most relevant (obfuscated, unfortunately) code, taken from Twitter's boot JavaScript file (found by inspecting the header of the logged-in Twitter homepage). I didn't want to directly copy and paste the link, in case it's personalized to my Twitter account.

One-page scroll problems

I am using a free wordpress theme (I know, that is part of the problem :). It is a one-page scrolling theme with a sticky header. The problem is that the links do not hit the top of the sections - they scroll past. I did use CSS to increase the size of the header. If this throws it off that much how do I correct it in the coding?
site: http://whatsahead.com/closuremediatest/ (in the works)
The oddest part is it is not even consistent on where it lands on that section. What could be causing this?

It's not a Javascript problem but a CSS issue.
First of all you logo img is too big. it's pushing the navbar down and mismatching the calculation. Let's fix it:
.navbar-brand img {
max-height: 110px;
}
Then we must add a margin to the top of the page content.
.title-area, .page-content {
margin-top: 40px;
}
Add it in your custom.csss and it will solve your problem

I solved the problem by editing javascript file. It was removing the "sticky" class when scrolled to the far top which voided some of my css edits I wanted to stay with. Therefore, by editing the javascript so that the document was always "sticky" I was able to make the header larger as I desired.

jQuery background slideshow

I'm trying to create a background slideshow with fade effect, I've found this script which does this beautifully: http://srobbin.com/jquery-plugins/backstretch/
The problem that I encounter is that it re-sizes the image, which I would like to disable / remove.
This is the code:
/*! Backstretch - v2.0.3 - 2012-11-30
* http://srobbin.com/jquery-plugins/backstretch/
* Copyright (c) 2012 Scott Robbin; Licensed MIT */ (function (e, t, n) {
"use strict";
e.fn.backstretch = function (r, s) {
return (r === n || r.length === 0) && e.error("No images were supplied for Backstretch"), e(t).scrollTop() === 0 && t.scrollTo(0, 0), this.each(function () {
var t = e(this),
n = t.data("backstretch");
n && (s = e.extend(n.options, s), n.destroy(!0)), n = new i(this, r, s), t.data("backstretch", n)
})
}, e.backstretch = function (t, n) {
return e("body").backstretch(t, n).data("backstretch")
}, e.expr[":"].backstretch = function (t) {
return e(t).data("backstretch") !== n
}, e.fn.backstretch.defaults = {
centeredX: !0,
centeredY: !0,
duration: 5e3,
fade: 0
};
var r = {
wrap: {
left: 0,
top: 0,
overflow: "hidden",
margin: 0,
padding: 0,
height: "100%",
width: "100%",
zIndex: -999999
},
img: {
position: "absolute",

}
}, i = function (n, i, o) {
this.options = e.extend({}, e.fn.backstretch.defaults, o || {}), this.images = e.isArray(i) ? i : [i], e.each(this.images, function () {
e("<img />")[0].src = this
}), this.isBody = n === document.body, this.$container = e(n), this.$wrap = e('<div class="backstretch"></div>').css(r.wrap).appendTo(this.$container), this.$root = this.isBody ? s ? e(t) : e(document) : this.$container;
if (!this.isBody) {
var u = this.$container.css("position"),
a = this.$container.css("zIndex");
this.$container.css({
position: u === "static" ? "relative" : u,
zIndex: a === "auto" ? 0 : a,

}), this.$wrap.css({
zIndex: -999998
})
}
this.$wrap.css({
position: this.isBody && s ? "fixed" : "absolute"
}), this.index = 0, this.show(this.index), e(t).on("resize.backstretch", e.proxy(this.resize, this)).on("orientationchange.backstretch", e.proxy(function () {
this.isBody && t.pageYOffset === 0 && (t.scrollTo(0, 1), this.resize())
}, this))
};
i.prototype = {
resize: function () {
try {
var e = {
left: 0,
top: 0
}, n = this.isBody ? this.$root.width() : this.$root.innerWidth(),
r = n,
i = this.isBody ? t.innerHeight ? t.innerHeight : this.$root.height() : this.$root.innerHeight(),
s = r / this.$img.data("ratio"),
o;
s >= i ? (o = (s - i) / 2, this.options.centeredY && (e.top = "-" + o + "px")) : (s = i, r = s * this.$img.data("ratio"), o = (r - n) / 2, this.options.centeredX && (e.left = "-" + o + "px")), this.$wrap.css({
width: n,
height: i
}).find("img:not(.deleteable)").css({
width: r,
height: s
}).css(e)
} catch (u) {}
return this
},
show: function (t) {
if (Math.abs(t) > this.images.length - 1) return;
this.index = t;
var n = this,
i = n.$wrap.find("img").addClass("deleteable"),
s = e.Event("backstretch.show", {
relatedTarget: n.$container[0]
});
return clearInterval(n.interval), n.$img = e("<img />").css(r.img).bind("load", function (t) {
var r = this.width || e(t.target).width(),
o = this.height || e(t.target).height();
e(this).data("ratio", r / o), e(this).fadeIn(n.options.speed || n.options.fade, function () {
i.remove(), n.paused || n.cycle(), n.$container.trigger(s, n)
}), n.resize()
}).appendTo(n.$wrap), n.$img.attr("src", n.images[t]), n
},
next: function () {
return this.show(this.index < this.images.length - 1 ? this.index + 1 : 0)
},
prev: function () {
return this.show(this.index === 0 ? this.images.length - 1 : this.index - 1)

return this.paused = !0, this
},
resume: function () {
return this.paused = !1, this.next(), this
},
cycle: function () {
return this.images.length > 1 && (clearInterval(this.interval), this.interval = setInterval(e.proxy(function () {

},
destroy: function (n) {
e(t).off("resize.backstretch orientationchange.backstretch"), clearInterval(this.interval), n || this.$wrap.remove(), this.$container.removeData("backstretch")
}
};
var s = function () {
var e = navigator.userAgent,
n = navigator.platform,
r = e.match(/AppleWebKit\/([0-9]+)/),
i = !! r && r[1],
s = e.match(/Fennec\/([0-9]+)/),
o = !! s && s[1],
u = e.match(/Opera Mobi\/([0-9]+)/),
a = !! u && u[1],
f = e.match(/MSIE ([0-9]+)/),
l = !! f && f[1];
return !((n.indexOf("iPhone") > -1 || n.indexOf("iPad") > -1 || n.indexOf("iPod") > -1) && i && i < 534 || t.operamini && {}.toString.call(t.operamini) === "[object OperaMini]" || u && a < 7458 || e.indexOf("Android") > -1 && i && i < 533 || o && o < 6 || "palmGetResource" in t && i && i < 534 || e.indexOf("MeeGo") > -1 && e.indexOf("NokiaBrowser/8.5.0") > -1 || l && l <= 6)
}()
})(jQuery, window);
I randomly tried renaming "resize" but that didn't work out too well.

I tried hardly to understand your question but I'm still not sure if I understood your question correctly, anyway my solution if you are looking to keep all the images in the same size always for every image is adding min width and min-height values to the css style of the image, if the style of the image is "img: { }" so:
img: {
position: "absolute",
display: "none",
margin: 0,
padding: 0,
border: "none",
width: "value",
height: "value",
min-width: "same value",
min-height: "same value",
maxWidth: "none",
zIndex: -999999
}
Not sure but that's the solution for what I understood.
