I am new to javascript and have come up with this counter
Here is the JSFiddle - http://jsfiddle.net/ep6s616z/
and below is the javascript
I'm trying to figure out how i could add more values so that it goes up to 20 on the counter tool.
It must stay the same size, so how could i achieve this?
Would the new values be hidden and slide in?
Any help would be much appreciated!
var pages = ["1", "2", "3", "4", "5", "6", "7", "8"];
$(document).ready(function () {
var num = 1;
updatePrice(num);});
function updatePrice(num) {
pages.forEach(function(entry) {
if (entry == num) {
document.getElementById(entry).className = "page-selected page";
}
else {
document.getElementById(entry).className = "page";
}
document.getElementById('circle').innerHTML = num });
}
function addOne() {
var current = document.getElementsByClassName('page page-selected')[0].id
if (current < 8) {
current++;
updatePrice(current);
}
}
function takeOne() {
var current = document.getElementsByClassName('page page-selected')[0].id
if (current > 1) {
current--;
updatePrice(current);
}
}
I did a complete re-write as the events are far cleaner in pure jQuery. I also added an extra div to allow the scrolling you wanted:
JSFiddle: http://jsfiddle.net/TrueBlueAussie/ep6s616z/18/
Simpler HTML:
<div id="circle">1</div>
<div id="calculator">
<div id="slider-left">-</div>
<div id="slider">
<div id="page-holder"></div>
</div>
<div id="slider-right">+</div>
</div>
Code:
// Generate n items
for (var i = 1; i <= 20; i++) {
$('#page-holder').append($('<div>').addClass('page').text(i));
}
// Outer slider - allows for scroller
var $slider = $('#slider');
// Actual page holding div
var $pageHolder = $('#page-holder');
// Listen for clicks on any .page divs
$pageHolder.on('click', 'div.page', function (e) {
var $div = $(this);
$('#page-holder .page').removeClass('page-selected');
$div.addClass('page-selected');
$('#circle').html($div.html());
// Ensure the element is visible - of not scrill it into view
var offset = $div.offset();
// Range of the visible area
var areaStart = $slider.scrollLeft();
var areaEnd = areaStart + $slider.width();
var x = ($div.index() + 1) * $div.outerWidth();
if (offset.left > areaEnd)
{
$slider.animate({scrollLeft: x}, 100);
}
else if (offset.left < areaStart)
{
$slider.animate({scrollLeft: x-$div.width()}, 100);
}
});
$('#slider-right').click(function () {
var $div = $('#page-holder .page-selected');
if (!$div.length) {
$div = $('#page-holder .page:first');
} else {
$div = $div.next();
}
$div.trigger('click');
});
$('#slider-left').click(function () {
var $div = $('#page-holder .page-selected');
if (!$div.length) {
$div = $('#page-holder .page').last();
} else {
$div = $div.prev();
}
$div.trigger('click');
});
Note: the scrolling to keep it in view is not perfect, as the range checks are not quite right, but you need something to do. :)
i guess this is what u wanted . i have added a button control for adding the more limits on the slider.
HTML code
<input id="add" name="addmore" type="button" value="AddMore" />
Jquery code:
$('#add').on('click', function () {
var divEle = '<div onClick="updatePrice(this.id)" id="' + count + '" class="page">' + count + '</div>';
$('#calculator').width($('#calculator').width() + sizeCounter);
$('#page-holder').width($('#page-holder').width() + sizeCounter);
$('#page-holder').append(divEle);
pages[count - 1] = count;
count++;
if (count == 10) sizeCounter += 4;
});

I need to make it working for all my elements under Which nothing should fade (images).
Currently works only for the div.logo tag
I guess at the moment the reason mine <h1> element is now allowing animations underneath is that when I am getting the .top(), .left() and so on, you are doing it for the last element in the list.
I need to get the borders of each element in the resulting list.
Any help would be much appreciated

I am use this code for Writing Text Effect:
<script type="text/javascript">
$(document).ready(function () {
function changeText(cont1, cont2, speed) {
var Otext = cont1.text();
var Ocontent = Otext.split("");
var i = 0;
function show() {
if (i < Ocontent.length) {
cont2.append(Ocontent[i]);
i = i + 1;
};
};
var Otimer = setInterval(show, speed);
};
$(document).ready(function () {
changeText($("#TypeEffect p"), $(".p2"), 150);
});
});
</script>
but its not working for multiline, I use this code:
changeText($("#TypeEffect p, #TypeEffect br"), $(".p2"), 150);
so, its not working.
please help me for Writing Text Effect in multi line.
Try
$(document).ready(function () {
function changeText(cont1, cont2, speed) {
var contents = $(cont1).contents().map(function () {
if (this.nodeType == 3) {
if ($.trim(this.nodeValue).length) {
return this.nodeValue.split("")
}
} else {
return $(this).clone().get();
}
}).get();
var i = 0;
function show() {
if (i < contents.length) {
cont2.append(contents[i]);
i = i + 1;
} else {
clearInterval(Otimer)
}
};
var Otimer = setInterval(show, speed);
};
$(document).ready(function () {
changeText($("#TypeEffect p"), $(".p2"), 150);
});
});

I Have find a javascript code that works perfectly for showing a DIV.
but this code works only for showing one div for each page.
i want to include many DIVS for hiding and showing in the same page.
I was try to replace the div id and show/hide span id with a rundom php number for each include, but still is not working.
so how i have to do it?
the JS code:
var done = true,
fading_div = document.getElementById('fading_div'),
fade_in_button = document.getElementById('fade_in'),
fade_out_button = document.getElementById('fade_out');
function function_opacity(opacity_value) {
fading_div.style.opacity = opacity_value / 100;
fading_div.style.filter = 'alpha(opacity=' + opacity_value + ')';
}
function function_fade_out(opacity_value) {
function_opacity(opacity_value);
if (opacity_value == 1) {
fading_div.style.display = 'none';
done = true;
}
}
function function_fade_in(opacity_value) {
function_opacity(opacity_value);
if (opacity_value == 1) {
fading_div.style.display = 'block';
}
if (opacity_value == 100) {
done = true;
}
}
// fade in button
fade_in_button.onclick = function () {
if (done && fading_div.style.opacity !== '1') {
done = false;
for (var i = 1; i <= 100; i++) {
setTimeout((function (x) {
return function () {
function_fade_in(x)
};
})(i), i * 10);
}
}
};
// fade out button
fade_out_button.onclick = function () {
if (done && fading_div.style.opacity !== '0') {
done = false;
for (var i = 1; i <= 100; i++) {
setTimeout((function (x) {
return function () {
function_fade_out(x)
};
})(100 - i), i * 10);
}
}
};
Check out the Fiddle, you can edit code based on your needs ;)
$(function() {
$('.sub-nav li a').each(function() {
$(this).click(function() {

Am just posting this in case someone was trying to answer.
I have a JS Function which is called in document.ready. The intent is as it scrolls to the bottom window, it'll load more from the JSON API.
The API has the parameter offset and limit. Offset controls which subset of results you are seeing. For ex. 20-40 would be offset=20 and limit controls how many you can view at once.
I thought I would approach this with a recursive function which calls itself each time the user goes to the bottom of the window, with window.scroll. Once they go to the bottom, it'll increment the offset by 20 each time, then run the function again.
Problem: I can't seem to get it to increment the variable by 20 to make this work. Thoughts?
function getData(offset) {
var jsonCallback = "&jsoncallback=?";
//var offset = 20;
//var offset += 20;
var limit = 20;
var characterURL = "http://api.example.com/character&byId=" + characterID + "&offset=" + offset + "&limit=" + limit;
$.getJSON(characterURL + jsonCallback, function(data) {
for (i=0; i < (data.data.results).length; i++) {
var $characterUl = $("<ul>");
$characterUl.appendTo("#characterComics");
$("<li>").text(data.data.results[i].title).appendTo($characterUl);
$("<li>").text(data.data.results[i].id).appendTo($characterUl);
$("<li>").text(data.data.results[i].release_date).appendTo($characterUl);
if (data.data.results[i].release_date > 0) {
$characterLi.text(data.data.results[i].issue_number).appendTo($characterUl);
}
}
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() > $(document).height() - 10) {
while ((data.data.results).length === offset || (data.data.results).length > offset) {
offset = offset+20;
$("<div>").text(offset).appendTo("body");
getComics(offset);
}
}
});
});
}
$(document).ready(function() {
var $characterComics = $("<div>", {id : "characterComics"});
$characterComics.appendTo("body");
getData(0);
});
UPDATED
Read this more as a pseudo-code
function getData(offset) {
var jsonCallback = "&jsoncallback=?",
characterURL = "http://api.example.com/character&byId=" + characterID + "&offset=" + offset + "&limit=" + limit;
$.getJSON(characterURL + jsonCallback, function(data) {
for (i=0; i < (data.data.results).length; i++) {
var $listItem = $("<li>");
listItem.append("<span>"+data.data.results[i].title+"</span>");
listItem.append("<span>"+data.data.results[i].id+"</span>");
listItem.append("<span>"+data.data.results[i].release_date+"</span>");
if (data.data.results[i].release_date > 0) {
listItem.append("<span>"+data.data.results[i].issue_number+"</span>");
}
listItem.appendTo($characterUl);
itemsLoaded++;
}
});
}
$(document).ready(function() {
var $characterComics = $("<div>", {id : "characterComics"}),
$characterUl = $("<ul>"),
offset = 0,
itemsLoaded = 0;
limit = 20;
$characterComics.appendTo("body");
$characterUl.appendTo($characterComics);
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() > $(document).height() - 10) {
if ("check here if you reached your offsets") {
offset = offset+20;
getData(offset);
}
}
});
// get your first set of data
getData(0);
});
The script below creates a slider widget the takes a definition list and turns it into a slide deck. Each dt element is rotated via css to become the "spine", which is used to reveal that dt's sibling dd element.
What I'm trying to do is to enhance it so that I can have the option to remove the spines from the layout and just use forward and back buttons on either side of the slide deck. To do that, I set the dt's to display:none via CSS and use the code under the "Remove spine layout" comment to test for visible.
This works fine to remove the spines, now I need to dynamically create 2 absolutely positioned divs to hold the left and right arrow images, as well as attach a click handler to them.
My first problem is that my attempt to create the divs is not working.
Any help much appreciated.

Creating elements in jQuery is easy:
$newDiv = $('<div />');
$newDiv.css({
'position': 'absolute',
'top': '10px',
'left': '10px'
});
$newDiv.on('click', function() {
alert('You have clicked me');
});
$('#your_container').append($newDiv);
