carousel javascript several times - javascript

I wanna use this carousel :
[http://codepen.io/ScottMarshall/pen/FwxpH][1] on a forum, but when I repeat the code, it doesn't work well.
Can you help me ?
here, it's working, but the second container doesn't want and I don't want to change anything in the HTML...
JSFiddle

Here is working fiddle: http://jsfiddle.net/1x6251wc/2/
This is the key change to get the context "Front" instead of all of them:
var $front = $this.parent().find(".Front");
It's a poorly written plugin, but this change should get it to work across multiple instances.

How do I get an array of divs with a specific class?

So I've been working on this web-project that demands a gallery with a slider underneath it. I've used this JavaScript so far to solve the problem in a forEach(element) function:
var divnumber = Array.from(element.parentNode.children).indexOf(element);
So the pagination changes by the index of the clicked element.
But since I need to make it responsive and the graphic designer demands something different in the mobile view I would need to get the number of the divs by using their class. Basically - the same array but different values.
Is there any way to tweak that line of code a bit to let it get the index of the element by its class instead of their parent? Here's the pen for more: https://codepen.io/ridonibishi/pen/BaNyBva
Thank you in advance!
Try using:
var divnumber = Array.from(document.getElementsByClassName('class')).indexOf(element);
It works as intended.

Javarscript issues with dynamic tooltipster

I'm using Tooltipster which seems to be a nice jquery plugin.
Regardless I need to have my tooltips dynamic, which I don't believe should be that difficult. However I wrote a script and maybe it's because I'm tired or I don't know the simplest of javascript. Probably a combination of both.
I can't seem to get around this particular error. TypeError: $(...).tooltipster is not a function.
Here is the basic javascript code:
$("img#box_image[data-img-number]").hover(function(e) {
e.preventDefault();
i = $(this).attr("data-img-number");
var w = "http://trailerbrokerimages.s3.amazonaws.com/pics/" + i ;
window.console.log('before tool');
window.console.log('before tool ' +w);
tool(w);
});
var tool = function (w) {
$('.tooltip_two').tooltipster({content: $('<span><img style="height:191px; width:256px;"src="http://trailerbrokerimages.s3.amazonaws.com/pics/'+w+'" /></span>')});
An example of the code can be found at http://www.trailerbroker.com/go/listings/view/219
I suspect it's lame mistake on my part, thanks.
You have the same id box_image for multiple elements.
I understand that you're trying to make it unique by appending the data-img-number, but this won't work, as there's no way you can do this at run time unless your explicitly specifying different hover handlers.
Instead you could attach the hover handler to a class.
Add a class="box_image" to your <img /> elements and attach the hover as follows,
$(".box_image").hover(//rest of your code here//)
This should give you the desired functionality.
I solved this problem by using twitter bootstrap popover. Don't waste your time with tooltipers.

jCarouselLite not working with <3 list items

EDIT: This is not a problem with the jQuery creating the appropriate markup from SharePoint Announcement List to use jCarouselLite. It seems to be a problem within jCarouselLite. I have done another jsfiddle with just the appropriate markup, not the jQuery/javascript conversion code, and the problem still occurs.
You can see the problem at http://jsfiddle.net/ayatollah/6RKNx/
Again it is only a problem with 1 or 2 list items. 3+ works fine. Should I be changing the markup, our jCarouselLite calling code to fix this?
Bounty will be offered as soon as it's available!
ORIGINAL===============================================================================
I have an Announcement List in a Sharepoint site that I want to convert to a jCarousel. The Announcement List is rendered as a table so I have put together some jQuery code to convert it to the required ul structure.
The jQuery seems to be doing its job but the jCarousel gives some weird behaviour. The first announcement displays as it should, then the second announcement scrolls in as it should. However, for each scroll after this it flashes up the first announcement, then scrolls in the second. When it should just scroll in the first again.
I had it working correctly but it was displaying blank announcements, so I introduced some code to filter out the blank announcements. Here is a jsfiddle to show you the problem.
http://jsfiddle.net/RzeEX/2/
The only change I made from the previous code was to add the extra boolean value:
&& $(listitem).text() != "\xa0"
Seen at: http://jsfiddle.net/RzeEX/3/
However, in the above fiddle the code works exactly as the previous one, but on my server it displays an extra blank announcement. Don't know why I can't replicate it here.
Anyway, anyone have any ideas?
EDIT: Actually just testing it with more than 2 announcements and it seems to work. See http://jsfiddle.net/RzeEX/4/
It is now working as expected, but have 2 announcements and it is still broke, have 1 announcement and nothing shows! It must be something to do with the jQuery as I would believe the jCarouselLite plugin to work.
See http://jsfiddle.net/RzeEX/5/ for the single announcement.
Since it is my understanding that you might have a dynamic list of elements, you can do something like this:
$('.viewport').jCarouselLite({
auto:1000,
speed:1000,
visible: $('#announcementList li').length
});
That way it won't matter if you have 1, 2 or 100 elements. It will always work as it should.
Here's the jsfiddle: http://jsfiddle.net/XS87c/
I think by setting visible:2 may give the desire result.
$('.viewport').jCarouselLite({
auto:5000,
speed:1000,
visible:2
});
let me know if it does not work.
how many do you want to be visible? what behaviour do you want if there is < # visible. I ran into this exact problem, and solved it by not applying the carosel if there was < # visible in the list.
something like this should do the trick:
if ((document.getElementById('viewport') != null) && $('#announcementList').find('li').length >= 3 ) {
$('.viewport').jCarouselLite({
auto: 5000,
speed: 1000
});
}
Complementing the solution of Irfan, you can do:
if(document.getElementById('viewport') != null) {
var options = {auto:5000,speed:1000};
//Here we count the number of items and set it for a better display for 2 and 1 item
if($('#viewport a').length <= 2) {
options.visible = $('#viewport a').length;
}
$('.viewport').jCarouselLite(options);
}
So if you have on or two elements you will see just one or two. But if you have more than two elements you will see just three elements.

Trying to fix table header, getting css issue

Initially I asked this Question and written my own plugin to achieve the same,But i am facing very strange issue regarding to css of table.
After applying the plugin table cells borders are getting dis-sorted.
jsFiddle of the problem: Problem demo
In fiddle you can see that after first cell of the first tr, the header border line and table border line don't line up. I want the border line of thead cells and td cells to line up.
Can anyone tell me how to achieve that?
Lets start by doing a bit of a clean up of the code you posted so I can actually read your code and maintain a firm grasp on reality while we go down this rabbit hole.
If you write clean code, your problems will be exceptionally easier to see.
So lets clean it up and watch as all the problems here reveal themselves.
Step one: Your jsFiddle sets it to run "onDomReady," which basically means you've got $(document).ready(...) calling all the code in the box, which is fine, except you're got another got $(document).ready(...) inside there. Lets change that.
Step two: Lets add some white space and proper indentation in there, and stop using these one letter variable names.
{} are scope brackets, they should indent, not cover everything, they let us know what part of scope something is in.
Don't write .each() loops on one line, this adds no value and makes your code confusing to read.
$t should be called something meaningful, lets try element, because it holds the $(this) element, which is the active element you're working with.
w should be called something meaningful, but since you only use it twice I'm just going with element.width().
o needs to be less ambiguious, lets go with obj.
Step three: Selection structures
if(typeof(i)=='number')o.height=i;
else if(typeof(i)=='object')o=i;
else if(typeof(i)=='undefined')o={height:300}
Break that up, make it readable. Saving lines doesn't make you a better program, writing clean and easily understandable code will.
Why not use the switch-case statement?
switch (typeof(i)){
case "number":
o.height=i;
break;
case "object":
o=i;
break;
case "undefined":
o={height:300};
break;
}
Step four: Don't in-line styles. Just don't. There's no reason to do it, and it makes everyone's life harder.
Instead, lets just place the styles gently into the style sheet where it belongs, and make the parent=$('...') line look like parent=$('<div><div></div></div>').appendTo('body');.
Step five: Closure doesn't pass any value to arguments
After a bit of clean up, we see this block of code:
self.width(self.width() -
function(width){
var parent,child;
if(width===undefined){
parent=$('<div><div></div></div>').appendTo('body');
child=parent.children();
width= (child.innerWidth()) - (child.height(99).innerWidth());
parent.remove();
}
return width;
}()
);
Okay, that's a problem. Lets cut out a few lines to point out the problem here:
self.width(
self.width() -
function(width){
/*...*/
if(width===undefined){
/*...*/
}
return width;
}()
);
So, a quick refresher on this pattern you have here:
(function(arg1){
/*code*/
})(data);
Data gets passed to arg1. Arg1 declaires a variable in the scope local to that function, it doesn't get anything from outside. Outside data is passed in through the set of () that call the function, which your code had left abandoned. Think of it this way:
var msg = function(text) {
alert(text);
};
Then you call it as...
msg("hello world");
What your closure is doing is almost the same thing, except where you define your function, you also call it. Thus...
(function(text) {
alert(text);
})("hello world");
So, you need to pass a value of some sort into there, other wise this whole thing is always undefined. Lets do that. What are we passing? I have no way to be sure. This is why programmers need to add comments to their code.
Step six: Comment your code so people other than yourself will look at this code and have not a damn clue what you truthfuly wanted to do, and can only guess. It's like you posted a 200 point bounty and didn't bother helping people who want to help you. Why are you doing this to yourself, dude? Why couldn't you just go //This is what this does to give me a hint? What did I ever do to you?
Step Seven: Lets see if we can make the JS changes work with the JS Fiddle
Great odin... that HTML's 2000 lines long?
Okay, I'm working with pastebin here for the sake of saving space in the post here.
Alright, you started off with this: http://pastebin.com/xjmm4cev
You're using a lot of no-wrap, and putting classes onto individual elements. You shouldn't have to do this on each HTML element, CSS takes care of that very effectively, so lets go ahead and just rip out all the nowrap=nowrap and class="header" stuff (we'll put it back in a moment, but only ONE per group, not each element).
Then lets get rid of the useless blank lines.
Lets run this through HTML tidy and get it nice and indented correctly.
http://pastebin.com/uHtSZ4h5
Much easier to read over. Okay, so what do we see here? Well, it looks like you keep going in circles, cutting and pasting the same thing again and again. You also in-line javascript such as using onchange and onclick attributes. This is generally an awful thing to do to your code, and makes it hard to maintain (as I'm sure you've seen with this 2000+ line beast of cut+paste 27 times in a row).
So, lets take a look here:
elements, not inside a form
Elements in a table that are outside of rows, but not head/body/footer sections of a table
Code that's a huge pain to maintain because it keep going in circles, if you need to change this, you're basically screwed.
Lets fix all that.
We're going to use events in the tags, rather than in-line things. So, all of those in-line onchange and click attributes get the boot.
All of these inputs that are just floating around need to get put into a form, and taken out of this place in tables that only rows or table sections belong in.
Figure out how we can not have excessive input elements, if we can help it.
What the heck is the )="" that you have on every input button? Deleted.
So, here's all of your hidden boxes: http://pastebin.com/LXZSkvyf which I've removed, because we don't have a anywhere.
And here's what the code looks like without all of these weird things in it: http://pastebin.com/MiaJTGpb
Much more readable, but still not quite there.
Step 8: What can you do to make the HTML of the table work better?
You're using Thead and Tbody, and that's good.
You're using attributes for things like cellpadding, that's bad.
You've given each body row an ID. I don't feel you needed to do this, but it's not always bad. However, I'll show you how you could work without it.
You give some selects a select-box class, but it's nowhere in the css. I've removed it.
You give a title attribute to the selects that says "option_value". The title attribute is generally used to make a tool-tip popup when you leave the mouse over something. I'm not sure what you're going to do here, but that's bound to confuse your user. I'd highly suggest giving something better than option_value in that place.
You keep using the ID Submit_FMS_AddDelivery. HTML ID tags are meant to be unique, and used only once on one element. You've got it 27 times, that's bad. I don't think you need an ID on it, so I've removed it.
You've also got input-btn going on, I'm removing it, because you haven't shown it's used anywhere.
You probably don't need any of these ID tags on select and TR to be honest, so I'm pulling them.
What's that look like? Basically, you've got what's almost just the data, in it's nice pure form. That's good. http://pastebin.com/UNS6CAtb
Step 9: What were you trying to do?
Lets step back and take a look here.
All you really wanted to do was keep a fixed header, but you've ended up doing a lot of JavaScript hacks and manipulating the DOM in a lot of places. We need to stop doing this. Is there a simpler way to do what you want?
I'll have to expand on how to make this function with the rest of your stuff, but I get up for work in a few hours. I'll update again with more... But we'll get there.
Right now, because I haven't fixed what I took out, it doesn't look right. But I'm tired.
So, here's where we are so far: http://jsfiddle.net/5C6z7/
Plus those inputs we took out (and will be going back in later, in a different way)
Looks like all you have to do is to take the padding into account: each cell has 3 px padding both left and righ so you have to add 6 px to the width:
$t.find('tr:first th').each(function(){cols.push($(this).width()+6);});
Otherwise the cells with only one word inside will "push" the actual width a bit wider so that the word will fit and other cells with space to move will compensate by becoming a bit narrower. The header and the body both do this independently with different contents which creates the difference in actual cell widths.
EDIT: For Firefox you also need to widen the table so that the cells fit. After calculating the column widths add
var actualWidth = $t.width()+cols.length*6;
$t.width( actualWidth );
And later change the wrapper to:
$wrap.css({width:actualWidth,height:o.height,overflow:'auto'});
EDIT 2: To have both the header and the body scroll simultaneously you need to wrap them both to an outer div that handles the scrolling.
var $outerWrap = $( '<div>' ).css( {width:"300px", overflow:'auto' } );
var $wrap=$('<div>').css(
{ width:actualWidth,height:o.height,"overflow-y":'auto', "overflow-x":'hidden' }
);
$firstRow.wrap( $outerWrap );
$firstRow.after( $wrap );
$wrap.append( $t );
Demo: http://jsfiddle.net/YcRTz/2/
What about replacing '<th>' tags with '<td>' tags?
No extra js code required.
http://jsfiddle.net/spQAh/7/
Okay so instead of troubleshooting or using anything complex, I came up with simple CSS + JS solution to your problem. Take a look at http://jsfiddle.net/TdLQT/
Obviously, the process of making header static, can be made dynamic, meaning trigger it after user scrolls a bit or have it there by default or count other object's position from top window and trigger static behavior when it reaches or exceeds certain pixels. I can provide that if you give me details on exact design of your HTML page.
Anyways, I as you can see, have used fixed pixel heights which you can choose not to or make them elastic or dynamic. What is important to know is that, though solution relies on JS a bit, output position is purely from CSS. I am using classes to manipulate the position.
the simple solution is that when you calculate the width of the column you do not include padding. So you need to change the line
$t.find('tr:first th').each( function() {
cols.push($(this).width());
});
to
$t.find('tr:first th').each( function() {
cols.push($(this).outerWidth());
});
if your cells have margins use .outerWidth(true)
This works in quirks mode with IE7&8 and Chrome IE8 has a problem in strict mode. However I believe that that problem is caused by the added scrollbar. If you want to use IE8 in strict mode you have to allow for the width of the vertical scrollbar..

Minimizable side panel in html

I'm looking for a simple javascript to create side panel with hiding after some action(ex. after clicking on some area). Something like this example but appearing from left side not from up to down as the example works.
Will be appreciated for any help :)
You have 2 options. You can either use JQuery or scriptaculous to do this. There are plenty of examples and tutorials on the internet or you can simply use java script to this.
First download émile It's a very simple javascript animation framework.
Since you didn't provide any HTML markup, I'm assuming you have something like this.
<div id="side-panel">panel content..</div>
<div id="content">main content..</div>
and let's say your side-panel element has a CSS style of width:200px. Ok, now place a button somewhere and assign it a click event. Such as onclick="togglePanel()"
Here is the content of the togglePanel function:
function togglePanel(){
var panel = document.getElementById('side-panel');
if(!panel.__closed){
emile(panel, 'width:0px');
panel.__closed = true;
}else{
emile(panel, 'width:200px');
panel.__closed = false;
}
}
If you check the documentation of the emile framework you can do lot's of other cool things.
as you haven't provided us your code (which you have build) that's why I'm just giving a code to help you (And I don't know that this is a right answer or not). This code needs jQuery Ver.1.4 at least I think so, but I'm not clear. Anyways let's get started. Here is a link to live demo.
Hope this helps!
