I have written the below code on window resize vent
$(window).resize(function () {
var width = $(window).width();
if( width <= 768){
$.scrollify.destroy();
}else{
$.scrollify.update();
}
}
Based on the title of the question I would do something like this:
function scroll_page(){
if(window.innerWidth<1260){
if(window.innerHeight > window.innerWidth){
$.scrollify.destroy();
}
}
else{
$(function() {
$.scrollify({
section : "section"
});
});
}
}
window.addEventListener('resize', function(event){
scroll_page();
});

I want to do jqGrid shrinkToFit:false on screens of more than 320px and less than 768px. For 769px screens, I want to use shrinkToFit:true.
You can try this code:
function shrinkToFitPixels() {
var sreenwidth = window.screen.width * window.devicePixelRatio;
if( sreenwidth >= 320 && sreenwidth <= 768 ) {
return false;
} else {
return true;
}
}
$("#grid").jqGrid({
...
shrinkToFit : shrinkToFitPixels(),
...
});
Kendo pie chart explode function not working:
$( e.sender.dataSource.options.data ) //this line become null..
following are javascript:
seriesClick: function(e){
$( e.sender.dataSource.options.data ).each( function ( i, item ) {
if ( item.Description != e.category )
{
item.Exploded= false;
}
else
{
item.Exploded= true;
}
} );
createChart();
}
The Explode clicked pie chart segment demo shows how to do this. Here is the relevant code:
seriesClick: function(e){
$.each(e.sender.dataSource.view(), function() {
// Clean up exploded state
this.explode = false;
});
// Disable animations
e.sender.options.transitions = false;
// Explode the current slice
e.dataItem.explode = true;
e.sender.refresh();
}
this is my simple test code for lazy load
http://codepen.io/kevkev/pen/bVVGdE
it works so far .. but the thing is that hidden images in an onclick function for buttons etc. doesnt work!
(watch through my code and scroll to end and push the button)
you can see in the network feedback that it already had load the images.
i could figure out that the problem is "display:none"
.pop {
display:none;
z-index:99;
position:absolute;
width:100%;
height:auto;
background:inherit;
}
Because display: none; elements are unknown in position. And the lazyloader doesn't know, when and if you change this. Therefore it decides to eager load it. If you want a lazyloader that automatically detects this use https://github.com/aFarkas/lazysizes/.
As alternative I would recommend justlazy, because it's more lightweight and don't uses jQuery.
1. Define placeholder (similar to that what you have done):
<span data-src="path/to/image" data-alt="alt" data-title="title"
class="placeholder">
</span>
2. Initialize lazy loading after your button click:
$(document).ready(function () {
$("#art").click(function () {
$("#art_pop").fadeIn(300);
Justlazy.registerLazyLoadByClass("placeholder", {
// image will be loaded if it is 300 pixels
// below the lower display border
threshold: 300
});
});
// other code ..
});
thanks guys! but I also got a working solution on this:
http://codepen.io/kevkev/full/meebpQ/
$(document).ready(function () {
$("#art").click(function () {
$("#art_pop").fadeIn(300);
});
$(".pop > span, .pop").click(function () {
$(".pop").fadeOut(600);
});
});
;(function($) {
$.fn.unveil = function(threshold, callback) {
var $w = $(window),
th = threshold || 0,
retina = window.devicePixelRatio > 1,
attrib = retina? "data-src-retina" : "data-src",
images = this,
loaded;
this.one("unveil", function() {
var source = this.getAttribute(attrib);
source = source || this.getAttribute("data-src");
if (source) {
this.setAttribute("src", source);
if (typeof callback === "function") callback.call(this);
}
});
function unveil() {
var inview = images.filter(function() {
var $e = $(this);
if ($e.is(":hidden")) return;
var wt = $w.scrollTop(),
wb = wt + $w.height(),
et = $e.offset().top,
eb = et + $e.height();
return eb >= wt - th && et <= wb + th;
});
loaded = inview.trigger("unveil");
images = images.not(loaded);
}
$w.on("scroll.unveil resize.unveil lookup.unveil", unveil);
unveil();
return this;
};
})(window.jQuery || window.Zepto);
/* OWN JAVASCRIPT */
$(document).ready(function() {
$("img").unveil(200, function() {
$(this).load(function() {
this.style.opacity = 1;
});
});
});
I want to write a ckeditor plugin that adds a checkbox to the toolbar.
When an img element is selected, the checkbox should reflect whether the image has a certain class or not.
When something else than an image is selected, the checkbox should be
disabled, or maybe invisible.
When I check or uncheck the checkbox, the class should be added/removed to/from the img.
In other words, I want to add something else than a button to the toolbar (those that are added with editor.ui.addButton), and that something should be a checkbox.
How do I do that?
I managed to do it anyway, using editor.ui.add and editor.ui.addHandler. Here is a screenshot:
plugin.js:
CKEDITOR.plugins.add('add_zoomable_to_image',
{
init: function( editor )
{
var disabled_span_color = "#cccccc";
var enabled_span_color = "#000000";
var cb;
var span;
var html =
"<div style='height: 25px; display: inline-block'>" +
"<div style='margin: 5px'><input class='add_zoomable_cb' type='checkbox' disabled='disabled'>" +
"<span class='add_zoomable_span' style='color: " + disabled_span_color + "'> Add zoomable to image</span>" +
"</div>" +
"</div>";
editor.ui.add('add_zoomable_to_image', "zoomable_button", {});
editor.ui.addHandler("zoomable_button",
{
create: function ()
{
return {
render: function (editor, output)
{
output.push(html);
return {};
}
};
}
});
editor.on("selectionChange", function()
{
var sel = editor.getSelection();
var ranges = sel.getRanges();
if (ranges.length == 1)
{
var el = sel.getStartElement();
if (el.is('img'))
{
enable_input();
if (el.hasClass('zoomable'))
check_cb();
else
uncheck_cb();
}
else
disable_input();
}
else
disable_input();
});
editor.on("instanceReady", function ()
{
cb = $('.add_zoomable_cb');
span = $('.add_zoomable_span');
cb.change(function()
{
var element = editor.getSelection().getStartElement();
if (cb.is(':checked'))
element.addClass('zoomable');
else
element.removeClass('zoomable');
});
});
function enable_input()
{
cb.removeAttr('disabled');
span.css('color', enabled_span_color);
}
function disable_input()
{
uncheck_cb();
cb.attr('disabled', 'disabled');
span.css('color', disabled_span_color);
}
function check_cb()
{
cb.attr('checked', 'checked');
}
function uncheck_cb()
{
cb.removeAttr('checked');
}
}
});
CKEditor doesn't include the option to add a checkbox to the toolbar, so your first step is to look at their code and extend it to add the checkbox.
Then look at how other buttons work to modify the content and detect when the selection in the editor changes to reflect its new state, and apply those ideas to your checkbox.
ok so im having a hard time hiding some layout sections (divs in my layout page and im using mvc3).
I have this js fragment which is basically the main logic:
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
});
//Cookies Functions========================================================
//Cookie for showing the right container
if ($.cookie('right_container_visible') === 'false') {
if ($('#RightContainer:visible')) {
$('#RightContainer').hide();
}
$.cookie('right_container_visible', null);
} else {
if ($('#RightContainer:hidden')) {
$('#RightContainer').show();
}
}
as you can see, im hidding the container whenever i click into some links that have a specific css. This seems to work fine for simple tests. But when i start testing it like
.contentExpand click --> detail button click --> .contentExpand click --> [here unexpected issue: the line $.cookie('right_container_visible', null); is read but it doesnt set the vaule to null as if its ignoring it]
Im trying to understand whats the right logic to implement this. Anyone knows how i can solve this?
The simpliest solution is to create variable outside delegate of bind.
For example:
var rightContVisibility = $.cookie('right_container_visible');
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
rightContVisibility = "false";
});
if (rightContVisibility === 'false') {
...
}
The best thing that worked for me was to create an event that can catch the resize of an element. I got this from another post but I dont remember which one. Anyway here is the code for the event:
//Event to catch rezising============================================================================
(function () {
var interval;
jQuery.event.special.contentchange = {
setup: function () {
var self = this,
$this = $(this),
$originalContent = $this.text();
interval = setInterval(function () {
if ($originalContent != $this.text()) {
$originalContent = $this.text();
jQuery.event.handle.call(self, { type: 'contentchange' });
}
}, 100);
},
teardown: function () {
clearInterval(interval);
}
};
})();
//=========================================================================================
//Function to resize the right container============================================================
(function ($) {
$.fn.fixRightContainer = function () {
this.each(function () {
var width = $(this).width();
var parentWidth = $(this).offsetParent().width();
var percent = Math.round(100 * width / parentWidth);
if (percent > 62) {
$('#RightContainer').remove();
}
});
};
})(jQuery);
//===================================================================================================
