I use the following script for a smooth scroll effect minus an amount of pixel on one page. The problem is, i click on one anchor link, the scroll effects works as it should but then i scroll back to the top of the page where the links are and click on another page. It doesnt work. I just copied the script from a webpage my javascript is very bad.
Thx for your help.
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top - 70;
$(this).click(function(event) {
if(event != 'undefined') {
event.preventDefault();}
$(scrollElem).animate({scrollTop: targetOffset}, 400, function(e) {
e.preventDefault();
location.hash = target;
});
});
}
}
});
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
}
There's an error in the code.
Where it says:
$(scrollElem).animate({scrollTop: targetOffset}, 400, function(e) {
e.preventDefault();
location.hash = target;
});
You are calling preventDefault() on nothing. Leave it as this and it will work:
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
location.hash = target;
});
The error was at the beggining of the code. Instead of using an each loop, you should add a clickevent to the anchor elements. By using the each loop, you only add the click event once, and thus on the second click the event is undefined and the code runs into an error.
Here's your code rewritten as a click event:
$('a[href*=#]').click(function(e){
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath && (location.hostname == this.hostname || !this.hostname) && this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top - 70;
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
if( e != 'undefined' ) {
e.preventDefault();
}
location.hash = target;
});
}
}
});
Hope this helps ;-)

I would say I am fairly decent with javascript and jQuery, well, enough to get the job done and done pretty well.
I do however lack a deep understanding of js.
I have created some functions for highlighting table elements.
ctrl+click toggles selections
shift+click+drag highlights selection
My question does not pertain to whether or not my implementation is the best way or not but ...
How do I abstract this functionality so I can add this functionality to any table. Like if I add more highlighting features and such and put this in its own .js file. How would I attach it to any html table?
Sorry if this has already been answered, but I could not think of what to search for.
Thank you.
****Newest Code****
This code is in its own .js file and is attached to my table.
All the current functionality is there. The only thing I am weary of is the .off() functions. In my case, I am reloading new tables.... as I type this, I realize I should just empty the tr's from the table instead of recreating a new table all the time, then I could get rid of the .off() calls.

you can wrap all this in a function since you have some local variables related to individual selection
$.fn.addEvents = function(obj) {
var properties = $.extend(true, {
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,
trajectory: null
}, obj || {});
return $(this)
.off('click')
.off('contextmenu')
.on('click', function() {
.....
})
.on('mouseleave', function(e) {
//rename your local variables with `properties.` prefix
properties.mouseleave = e.clientY;
if (properties.shifting && properties.mousing) {
tmptrajectory = properties.mouseenter - properties.mouseleave < 0 ? 1 : -1;
}
if ($(this).hasClass('selected') && properties.shifting && properties.mousing && properties.trajectory != null && properties.trajectory != tmptrajectory) {
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
....
});
}
usage
$('#datatablebody tr').addEvents({ shifting: false, ctrling: true }); //custom settings
$('#someother tr').addEvents(); //default settings
you could add that functionality to a class and add that class to the tables you want to affect...
Here I create the class .myTableBeh and all tables with that class will have the behaviour you programmed.
var shifting = false;
var ctrling = false;
var mousing = false;
var mouseenter = 0;
var mouseleave = 0;
var trajectory = null;
$('.myTableBeh tr')
.off('click')
.off('contextmenu')
.on('click', function()
{
if(!ctrling)
{
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
else if(ctrling && $(this).hasClass('selected'))
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
else if(ctrling && !$(this).hasClass('selected'))
{
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
})
.on('contextmenu', function(ev)

$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY);
return false;

Thanks to the answer from #JAG I was able to create a nice add on to any HTML table that handles highlighting.
Check out the fiddle for the working version and please use it if you find it helpful or useful for your site.
You can even implement keys to move the tr position up or down in the table. I removed my implementation because it was specific to the project I am working on.
I made it so you have to mouse over the table in order to interact with it and mouse leave to un-focus it.
https://jsfiddle.net/kwj74kg0/2/
//Add the events simply by running this
$('#dtable tr').addEvents(0);
/**
* This add on can be applied and customized to any html tr set i.e. $('#tableid tr').addEvents()
* It will add highlighting capability to the table.
*
* Single click highlight tr
* Click -> Shift + click highlight/toggle range
* Shift+MouseDown+Drag highlight/toggle range
* Ctrl+Click toggle item

I am trying to populate a splash screen on my website and it is populating if scroll pos is between 1-120, using following JS code.
Please suggest what should be done if I want to execute this on hover browser's and tab's cancel button?
How to read that, cause $(window).scrollTop(); won't return anything if it is less that 0.
function setHeightToEmergencyContainer () {
var getWindowHeight = $(window).height();
var setHeight = (getWindowHeight - 123)/2;
}
setHeightToEmergencyContainer();
$(window).resize(function() {
setHeightToEmergencyContainer();
});
function addEvent(obj, evt, fn) {
if (obj.addEventListener) {
obj.addEventListener(evt, fn, false);
}
else if (obj.attachEvent) {
obj.attachEvent("on" + evt, fn);
}
}
addEvent(window,"load",function(e) {
addEvent(document, "mouseout", function(e) {
e = e ? e : window.event;
var from = e.relatedTarget || e.toElement;
if (!from || from.nodeName == "HTML") {
// stop your drag event here
// for now we can just use an alert
setHeightToEmergencyContainer();
var scroll = $(window).scrollTop();
console.log("scroll pos :: "+scroll);
if(scroll > 0 && scroll <= 120){
console.log("show popup "+scroll);
$(".tso_pop-container").css({"width":"1366px","height":"700px","overflow":"auto","right":"-296px","top":"106px"});
}
//$.cookie("dontShowUrgencyContainer","yes");
}
});
addEvent(document, "mouseover", function() {
$(".tso_pop-container").css({"width":"0px","height":"0px","overflow":"hidden","right":"50%","top":"50%"});
});
});
//}
window.onblur = function(event) {
$(".tso_pop-container").css({"width":"0px","height":"0px","overflow":"hidden","right":"50%","top":"50%"});
}
first to get scrolled position of document use :
$('body').scrollTop() // webkit
$('html').scrollTop() // moz
for browser hover use :
$(window).mouseenter(function(){
var stop = $('html').scrollTop() == 0 ? $('body').scrollTop() : $('html').scrollTop()
if(stop <= 120){
// your code
}
});
hope this helps you.
I'm looking for the way to translate this block of code from jQuery to pure javascript. Is it possible?
jQuery(".menu2").each(function(){
$menu = jQuery(this);
$menu.find("li").unbind('mouseenter mouseleave').filter(".deeper").children("span.separator").addClass("parent");
$menu.find("li.deeper>a.parent, li.deeper>span.separator").unbind('click').bind('click', function(e) {
e.preventDefault();
jQuery(this).parent("li").children("ul").animate({height: 'toggle'}, 300, "jswing");
});
$menu.find("li a.parent > span.linker").click(function(){
if((typeof jQuery(this).parent().attr("href") != 'undefined') && jQuery(this).parent().attr("href") != "#"){
jQuery(this).parent().unbind('click');
myLink = jQuery(this).parent().attr("href");
window.location.href = myLink;
}
});
}
Thanks!
Of course it's possible. Whether it's a good idea or not is debatable, but here...
[].forEach.call(document.querySelectorAll(".menu2"),function(menu){
[].forEach.call(menu.getElementsByTagName("li"),function(li) {
li.__events = li.__events || {};
if( li.__events.mouseenter) {
li.removeEventListener('mouseenter',li.__events.mouseenter);
delete li.__events.mouseenter;
}
if( li.__events.mouseleave) {
li.removeEventListener('mouseleave',li.__events.mouseleave);
delete li.__events.mouseleave;
}
if( li.className.match(/\bdeeper\b/)) {
[].forEach.call(li.querySelectorAll("span.separator"),function(span) {
if( !span.className.match(/\bparent\b/)) span.className += " match";
});
}
});
[].forEach.call(menu.querySelectorAll("li.deeper>a.parent, li.deeper>span.separator"),function(elem) {
elem.__events = elem.__events || {};
if( elem.__events.click) {
elem.removeEventListener('click',elem.__events.click);
delete elem.__events.click;
}
elem.addEventListener('click',elem.__events.click = function(e) {
[].forEach.call(this.parentNode.getElementsByTagName('ul'),function(ul) {
if( ul.style.height == "auto") ul.style.height = "0px";
else ul.style.height = "auto";
// TODO: Implement animation here
});
return false;
},false);
});
[].forEach.call(menu.querySelectorAll("li a.parent>span.linker"),function(elem) {
elem.__events = elem.__events || {};
if( elem.__events.click) {
elem.removeEventListener('click',elem.__events.click);
delete elem.__events.click;
}
elem.addEventListener('click',elem.__events.click = function(e) {
if( this.parentNode.getAttribute("href") != "#") {
window.location.href = this.parentNode.href;
}
return false;
},false);
});
});
... I think it's fairly obvious why people use jQuery. Of course, I would have my own toolbox to make a lot of this code easier to manage ;)
I'm using a smooth scroll script for a site I'm currently working on, and I've got a really annoying problem what I've experienced before with the same script. It works nice and smoothly but when I click on one of the navigation points what should lead me to the div(or a) I'm trying to target, it shows me the targeting area for like 0.1 seconds, and then it starts to scroll. It doesn't happen everytime, but often enough to be annoying. How could I prevent this? Here is the script I'm talking about:
$(window).load(function(){
$(".contactLink").click(function(){
if ($("#contactForm").is(":hidden")){
$("#contactForm").slideDown("slow");
}
else{
$("#contactForm").slideUp("slow");
}
});
});
function closeForm(){
$("#messageSent").show("slow");
setTimeout('$("#messageSent").hide();$("#contactForm").slideUp("slow")', 2000);
}
$(window).load(function() {
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
$('a[href*=#]').each(function() {
if ( filterPath(location.pathname) == filterPath(this.pathname)
&& location.hostname == this.hostname
&& this.hash.replace(/#/,'') ) {
var $targetId = $(this.hash), $targetAnchor = $('[name=' + this.hash.slice(1) +']');
var $target = $targetId.length ? $targetId : $targetAnchor.length ? $targetAnchor : true;
if ($target) {
var targetOffset = $target.offset().top - 110;
$(this).click(function() {
$('html, body').animate({scrollTop: targetOffset}, 1400);
var d = document.createElement("div");
d.style.height = "101%";
d.style.overflow = "hidden";
document.body.appendChild(d);
window.scrollTo(0,scrollToM);
setTimeout(function() {
d.parentNode.removeChild(d);
}, 10);
return false;
});
}
}
});
});
setTimeout(function() {
d.parentNode.removeChild(d);
}, 10);
return false;
});
move the return false out of the setTimeOut
Found the solution:
$(this).click(function(e) {
e.preventDefault();
Now it rolls fine.
I'm having an odd problem on Safari (Mac OS only, Windows works fine), where my smooth scroll is not scrolling. It just jumps to the link, but works in all other browsers, even on windows Safari.
My jQuery is
<script type="text/javascript">
(function($){
$.extend({
smoothAnchors : function(speed, easing, redirect){
speed = speed || "slow";
easing = easing || null;
redirect = (redirect === true || redirect == null) ? true : false;
$("a").each(function(i){
var url = $(this).attr("href");
if(url){
if(url.indexOf("#") != -1 && url.indexOf("#") == 0){
var aParts = url.split("#",2);
var anchor = $("a[name='"+aParts[1]+"']");
if(anchor){
$(this).click(function(){
if($(document).height()-anchor.offset().top >= $(window).height()
|| anchor.offset().top > $(window).height()
|| $(document).width()-anchor.offset().left >= $(window).width()
|| anchor.offset().left > $(window).width()){
$('html, body').animate({
scrollTop: anchor.offset().top,
scrollLeft: anchor.offset().left
}, speed, easing, function(){
if(redirect){
window.location = url
}
});
}
return false;
});
}
}
}
});
}
});
})(jQuery);
</script>
and my HTML looks like this
<nav id="nav">
<ul id="navigation">
<li> ABOUT</li>
<a name="About"></a>
If anybody knows what the issue, please let me know!
Much appreciated.
Works great for me!
