I want to make animation highlighting each letter of the text. Is there jQuery plugin to highlight text on window scoll? Trying to figure out the lightweight way to achieve this.
That's what I wanted to make:
highlight();
$(window).on("scroll", function(){
highlight();
});
function highlight(){
var scroll = $(window).scrollTop();
var height = $(window).height();
$(".highlight").each(function(){
var pos = $(this).offset().top;
if (scroll+height >= pos) {
$(this).addClass("active");
}
});
}

I'm learning JS and JQ and I'm working on a simple parallax effect and I need help to get him right.
Here is the code: http://codepen.io/ronka/pen/JGxxBb.
$(document).ready(function(){
$('section[data-type="parallax"]').each(function(){
var $bgobj = $(this);
$(window).scroll(function(){
var $yPos = -($(window).scrollTop()- $bgobj.offset().top);
console.log($(this));
$bgobj.css('background-position','50% ' + $yPos +'px');
});
});
});
As you can see when you scroll you see the red background. I don't want it to show the red background just the image. what is the solution?
Try with something like this
$(document).ready(function(){
$('section[data-type="parallax"]').each(function(){
var $bgobj = $(this);
$(window).scroll(function(){
var yPos = $(window).scrollTop();
$bgobj.css('background-position','50% -' + (yPos*0.4) +'px');
});
});
});
I can't figure out of to make scroll, (when a div is clicked), and make it smooth. (like not going straight to the scroll position)
Here's my code:
$('.about-center').click(function() {
var div = document.getElementById('ABOUT');
var pos = div.offsetTop;
$(window).scrollTop(pos);
});
try this one:
$('.about-center').click(function() {
var div = $('#ABOUT');
var pos = div.offset().top;
$('html, body').animate({scrollTop:pos},2000); // will take two seconds to scroll to the element
});
I am creating a fixed position sub-nav menu bar for a responsive site. All the examples I can find of a fixed menu that sticks to top after scrolling are based on a set number of pixels from top.
However, since I am working a responsive site the pixels from top where I need the menu to come in are different based on viewport (on small screens, the menu should appear after more area scrolled down because the content fills are taller area of screen).
I have a working example and am using the following jquery script:
$(document).ready(function(){
$('#navigation a, #fixedbar a').on('click', function(e) {
e.preventDefault();
});
$(window).on('scroll',function() {
var scrolltop = $(this).scrollTop();
if(scrolltop >= 215) {
$('#fixedbar').fadeIn(250);
}
else if(scrolltop <= 210) {
$('#fixedbar').fadeOut(250);
}
});
});
As you can see the fixed bar fades in if more than 215 pixels scrolled from the top. Instead I'd like to have it appear after scrolling past a certain div. That way I know it will come in after user has fully scrolled past the intro text.
Here's my fiddle
Any good examples out there of what I want to do? Or easy way to modify the jquery script? Thanks in advance.
This modification will make it fade in after it passes the static nav
DEMO
var $nav = $("#navigation");
if(scrolltop >= $nav.offset().top + $nav.height()) {
$('#fixedbar').fadeIn(250);
}
else {
$('#fixedbar').fadeOut(250);
}

You need to fade out and fade in the navigation when the scroll reaches the bottom and the top of the navigation bar respectively.
var topOfDiv = $('#navigation').position().top;
var bottomOfDiv = $('#navigation').position().top+$('#navigation').outerHeight(true);
And fetched in your code:
$(document).ready(function(){
$('#navigation a, #fixedbar a').on('click', function(e) {
e.preventDefault();
});
$(window).on('scroll',function() {
var scrolltop = $(this).scrollTop();
var topOfDiv = $('#navigation').position().top;
var bottomOfDiv = $('#navigation').position().top+$('#navigation').outerHeight(true);
if(scrolltop >= bottomOfDiv) {
$('#fixedbar').fadeIn(250);
}
else if(scrolltop <= topOfDiv) {
$('#fixedbar').fadeOut(250);
}
});
});
$(document).ready(function ()
{
slider();
});
$(window).scroll(function ()
{
slider();
});
function slider()
{
if (document.body.scrollTop > 208)
$('#fixedMenu').fadeIn(0);
else
$('#fixedMenu').fadeOut(0);
}
I wrote this plugin but I'm having issues trying to position the tooltip so that it's completely centered above the parent container. I'm currently just calculating the width of the parent container that it's in and finding out where that is by getting it's left position, but it's always not completely centered.
Any ideas?
(function($) {
var toolTip = {
init: function() {
this.each(function() {
var $that = $(this);
// our boolean object to check if it already exists on the page
var $toolSpan = $('<div class="tooltip"><span class="tooltip_arrow"></span></div>');
var preloadImages = function() {
var tempImage = new Image();
tempImage.src = 'http://i.imgur.com/K5ynr.png';
tempImage = null;
};
preloadImages();
$that.mouseover(function() {
var $altText = $that.attr('alt');
var $parentWidth = $that.parent().width();
var $parentPos = $that.parent().position();
var $parentPosY = $parentPos.top;
var $parentPosX = $parentPos.left;
$that.parent().after($toolSpan);
$toolSpan.prepend($altText);
$that.parent().next($toolSpan).css('top', $parentPosY - 30).css('left', $parentPosX).fadeIn();
var $toolSpanWidth = $that.parent().outerWidth();
$that.parent().next('.tooltip').children('.tooltip_arrow').css('left', $toolSpanWidth / 2).fadeIn();
}).mouseout(function() {
$that.parent().next($toolSpan).text('').hide().remove();
});
});
} /* end init */
};
$.fn.toolTip = toolTip.init;
})(jQuery);

here you go - centered, all working, code a bit cleaner ...
http://jsfiddle.net/PBpWj/
though it can potentially go off screen if the tip text is too wide.
If you intention is so that the tooltip container is center aligned above the link containers (in this case the wrappers). Try modifying the following line of code:
$that.parent().next($toolSpan)
.css('top', $parentPosY - 30)
.css('left', $parentPosX + ($parentWidth/2) - ($toolSpan.width()/2))
.fadeIn();
See it at the following jsFiddle.
I am developing a website which have a scrolling newsticker in a strip using jquery.li-scroller.1.0.js.
page address is: http://www.designforce.us/demo/ticker/index.html
When we hover the mouse on the newsticker, strip is stop. At this stage i want to show a popup box right under the current li with its text. something i've done and when we hover the mouse pointer over the strip, newsticker stops and box is showing with its text.
PROBLEM:
jquery.li-scroller newsticker have a wrapper with {overflow:hidden} so if i add the popup box withing li then its not showing. Thats why i've coded the popup (.tickPop) withing a seperate space and white some script of jquery document ready. my script is:
$('ul#ticker01 li').each(function(e){
var iClass;
$(this).hover(function(){
iClass = $(this).attr('class');
$(this).css('height',$('tickPop').height()+30)
var offset = $(this).offset();
var left = offset.left;
var top = offset.top+20;
var iWidth = $(this).width();
var sText = $(this).children().html();
$(this).css('background','#f6f4f4');
$('.tickPop').css('left',left);
$('.tickPop').css('top',top);
$('.tickPop').css('width',iWidth);
$('.tickPop').css('display','block');
$('.tickPop').text(sText);
}, function(){
$('.tickPop').mouseleave(function(){
bHovering = false;
$(this).css('display','none');
});
$(this).css('background','transparent');
//$('.tickPop').css('display','none');
if(iClass == 'Yellow')
$(this).css('background','url(images/icon-yellow.jpg) left center no-repeat');
else
$(this).css('background','url(images/icon-white.jpg) left center no-repeat');
});
});
popup box called $('.tickPop') is hidden by default and when user hover on newsticker then jquery function set the attribute $('.tickPop').css('display','block') and it is visible.
Now problem is that as we move the mouse pointer over the popup box then newsticker is again start scrolling while i want when we mouseleave from the popup box then newsticker should start.
Dear Experts, Please advise..............?
Looking forward for a kind response.

You should modify jquery li-scroller sources.
watch this code (from li-scroller sources):
function scrollnews(spazio, tempo){
$strip.animate({left: '-='+ spazio}, tempo, "linear", function(){$strip.css("left", containerWidth); scrollnews(totalTravel, defTiming);});
}
scrollnews(totalTravel, defTiming);
// $strip = $(this) so it triggers when you're hover a news
$strip.hover(function(){
jQuery(this).stop();
},
function(){
var offset = jQuery(this).offset();
var residualSpace = offset.left + stripWidth;
var residualTime = residualSpace/settings.travelocity;
scrollnews(residualSpace, residualTime);
});
You should add something like:
var popup = jQuery('.tickPop');
popup.hover(function(){
$strip.stop();
},
function(){
var offset = jQuery(this).offset();
var residualSpace = offset.left + stripWidth;
var residualTime = residualSpace/settings.travelocity;
scrollnews(residualSpace, residualTime);
});
I didn't test that code but should work....
P.S. Sorry for the indentation
