I have to create instances of swiper dynamically. These swipers have dynamically filled image contents. I have been fighting this the whole day with my lacking skills and cannot get this to work.
There are no javascript console errors, so I am assuming something is very fundamentally wrong but I don't know what it is.
Here is the code:
<!-- The sliders are initiated very standard way, i skipped showing them. These are my paginations where I cannot get the pagination to be rendered -->
<div class="secondary-0 swiper-pagination-clickable swiper-pagination-bullets"></div>
<div class="secondary-1 swiper-pagination-clickable swiper-pagination-bullets"></div>
<div class="secondary-2 swiper-pagination-clickable swiper-pagination-bullets"></div>
<script>
// I get lots of image data from php here
var imagearrays = <?php echo json_encode( $images_multiarray_js ); ?>;
// initialize variables for use in the loop.
var i;
var subNameArray = [];
var subSwiper = [];
// Loop through the imagearrays variable and initiate swipers.
for (i = 0; i < imagearrays.length; i++) {
subNameArray[i] = imagearrays[i].imagenames;
subSwiper = new Swiper('.subswiper-' + i, { // all my swiper-containers have extra class "subswiper-0" "subswiper-1" etc.
pagination: { // my main issue: I cannot get this pagination to render. WHY?
el: '.secondary-' + i, //my paginations have class like "secondary-0"
clickable: true,
renderBullet: function (index, className) {
return '<span class="' + className + '"><div class="pagination-ball"></div>' + subNameArray[index] + '</span>';
}
},
loop:true,
effect: 'fade',
clickable:true,
disableOnInteraction:false,
});
}
</script>
This is what my imagearrays variable looks like, just to show you that it's fine.
[
{"controllertype":false,"imagenames":["name1","name2"]},
{"controllertype":true,"imagenames":["name3","name4"]},
{"controllertype":false,"imagenames":["name5","name6"]}
]
I tried to go line by line in debugging JS mode, but it looks like the console simply leaps over the "new Swiper(..." line and everything inside it. Again, no errors in console.
How to feel really stupid:
Spend half a day figuring out why your code doesn't work
On a whim go check that your swiper selector class is attached to the correct html element and realize that it is not
Go cry in stackoverflow
I'm sorry guys, this question is useless. Everything works as intended with that d'oh fix.

I using PhoneGap to create a Geolocation App following this excellent tutorial (link). Unfortunatelly, I'm having an issue that I can't figure out. The relevant parts that are giving me a headache are these:
//Section 1
$('#history').on('pageshow', function () {
tracks_recorded = window.localStorage.length;
$("#tracks_recorded").html("<strong>" + tracks_recorded + "</strong> workout(s) recorded");
$("#history_tracklist").empty();
for (i = 0; i < tracks_recorded; i++) {
$("#history_tracklist").append("<li><a href='#track_info' data-ajax='false'>" + window.localStorage.key(i) + "</a></li>");
}
$("#history_tracklist").listview('refresh');
});
//Section 2
$("#history_tracklist li a").on('click', function () {
$("#track_info").attr("track_id", $(this).text());
});
//Section 3
$('#track_info').on('pageshow', function () {
var key = $(this).attr("track_id");
$("#track_info div[data-role=header] h1").text(key);
var data = window.localStorage.getItem(key);
data = JSON.parse(data);
});
Section 1 works just fine, the data is stored, and the list is created without any issues. But then in Section 2 is when everything goes to hell. By clicking on the element, a new attribute (track_id) is supposed to be created, but it doesn't. Therefore, in Section 3, the "var key" won't get a value, and as a consequence, "var data" will be null also. As you can imagine, nothing works from there. What am I doing wrong here? I only included what I considered the relevant code, but if more is needed I'll do so. Thansk!
In section 2, I think you just need to delegate click handling to the "#history_tracklist" container, as follows :
$("#history_tracklist").on('click', "li a", function () {
$("#track_info").attr("track_id", $(this).text());
});
Without delegation you have a rule saying :
when any existing li a element within #history_tracklist is clicked execute my function
With delegation, you have a rule saying :
when any existing or future li a element within #history_tracklist is clicked execute my function
I'm attempting to make a menu bar that can have <li> elements added and removed. So far so good, but when I try and remove them I'm running into issues. I've toyed with this for a couple hours and now I'm wondering if this whole process could just be made easier (maybe an object?).
Anyways, here's the full code (80 lines), with comments to follow along.
var tabs = $('.accountSelectNav');
var titles = [];
var listItems = [];
// when the page loads check if tabs need to be added to the ul (menu bar)
$(document).ready(function(e) {
if ($.cookie('listItems') != null) {
console.log('not null');
//return "listItems" to it's array form.
listItems = JSON.parse($.cookie('listItems'));
$('.accountSelectNav').append(listItems);
}
});
$('.selectTable td:first-child').on('click', function(e) {
$('#home_select').removeClass('navHighlight');
//grab the text value of this cell
title = $(this).text();
$.ajax({
url:'core/functions/getAccountId.php',
type: 'post',
data: {'title' : title}
}).fail (function() {
alert('error');
}).done(function(data) {
accountId = $.trim(data);
// store values in the cookie
$.cookie('account_id', accountId, {expires : 7});
$.cookie('title', title, {expires : 7});
window.location = ('home_table.php');
});
// make sure the value is NOT currently in the array. Then add it
var found = jQuery.inArray(title, titles);
if (found == -1) {
titles.push(title);
addTab();
}
// make sure the value is NOT currently in the array. Then add it
found = jQuery.inArray(title, listItems);
if (found == -1) {
addListItem();
//place <li>'s in cookie so they may be used on multiple pages
$.cookie('listItems', JSON.stringify(listItems));
};
});
$("body").on("click", ".deleteImage", function (e) {
var removeTitle = $(this).closest('li').find('a').text();
var removeItem = $(this).closest('li')[0].outerHTML;
//remove title from "titles" array
titles = jQuery.grep(titles, function (value) {
return value != removeTitle;
});
//remove <li> from "listItems" array
listItems = jQuery.grep(listItems, function (value) {
return value != removeItem;
});
// this shows the <li> is still in the listItemsarray
console.log(listItems);
// put the array back in the cookie
$.cookie('listItems', JSON.stringify(listItems));
removeTab(this);
});
$("body").on("mouseover", ".accountSelectNav li", function(e) {
$(this).find('.deleteImage').show();
});
$("body").on("mouseleave", ".accountSelectNav li", function(e) {
$(this).find('.deleteImage').hide();
});
function addTab() {
tabs.append('<li class="navHighlight">' + '' + title + '' + '' + '<img src="images/delete.png" class="deleteImage"/>' + '' + '</li>');
};
function removeTab(del) {
$(del).closest('li').remove();
}
function addListItem() {
var s = ('<li class="navHighlight">' + '' + title + '' + '' + '<img src="images/delete.png" class="deleteImage"/>' + '' + '</li>');
listItems.push(s);
}
So you see I have two arrays of equal length that should always be the same length. One stores the title to be displayed in the tab, the other holds the html for the <li> which will be appended to the <ul>. I have no problem removing the title from its array. However removing the <li> from it's array is becoming a rather big hassle. You see when I get the <li> element after its been inflated the html inside does not exactly match what was put in, the browser adds style elements.
Example, the variable "removeItem" represents the html value of the selected <li> I wish to remove. It looks like this:
<li class="navHighlight">Test1<img src="images/delete.png" class="deleteImage" style="display: inline;"></li>
yet the value in my array "listItems" looks like this:
<li class="navHighlight">Test1<img src="images/delete.png" class="deleteImage"/></li>
So my attempt at removing it from my array always fails because they aren't a perfect match.
Now my question is how do I remove this <li> item? Also is there an easier way to do this whole process and I'm just not seeing it?
Thanks for your time.
EDIT
Fiddle by request here
Easiest way I can explain it.
Click the link to the fiddle.
Click any cell in the "App Name" column
This will add a <li> to the <ul> (menu) above of the table
When you hover over the <li> a picture appears
Click the picture
This should remove the <li>, both from the <ul> and from the array listItems
right now it does not
In the process of making this easier to check, I've taken your JSFiddle and did the following:
removed extra console.log and comments
removed interaction with cookies (since I did not have them in the first place, I figured they wouldn't just the first scenario)
After doing so I reached a point (you can see it here) where the desired functionality just works.
I even went ahead and removed the ajax stuff because that alert was driving me crazy. (here)
Since this works fine, my guess is that your issue lies between the lines that I removed.
Your usage of cookies is as follows:
To load existing tabs and add them back again
To save account_id and title, which is not used back again
To persist the listItems after a new item has been added
I then opened up the console with your version of the fiddle and the execution of javascript stops at $.cookie() with the error undefined is not a function.
This clearly indicates that the issue present in the Fiddle is that jQuery.cookie is not present and so those calls are halting the execution of the rest of your script. This also explains why it just started working when I took them out.
I posted the whole process of how I got there to indicate how I trimmed down the problem to specific parts, which is useful to reduce the problem space. When you're out of options and reach a place when you're lost, it's easier to post a question with less code and the specific part of the problem that you've identified. This will help you in finding the issues that you're facing and StackOverflow to provide proper answers to your questions.
Hope it helps!
Here is the solution I came up with. It should be much easier for people to understand than my original post. Although it's a long read it may be worth it, especially for new developers.
The point of this code is to make a menu bar out of an un-ordered list or <ul>. The menu bar needs to be used on multiple pages. So I'll be using cookies.
I start with this code to get a text value from my table.:
$('.selectTable td:first-child').on('click', function(e) {
// This value will be used later for the name of the tab or `<li>` inside our menu bar or `<ul>`
title = $(this).text();
});
Then I place the value in an array. I do this only if the array does not already have this string inside it. I do not want duplicates:
var found = jQuery.inArray(title, titles);
var titles = [];
if (found == -1) {
titles.push(title);
}
Then I store the array into a cookie, using a library like this:
$.cookie('titles', JSON.stringify(titles));
Now when any page loads that needs this menu bar I run this code to check if there are any values:
$(document).ready(function() {
if ($.cookie('titles') != null) {
titles = JSON.parse($.cookie('titles'));
}
});
Now I need to loop through the array. When I loop through the array I have to do 3 things:
1) Grab the string value.
2) Add the html to my new string so it becomes a list item or <li>.
3) Append the newly created <li> to our <ul>.
Like so:
for(var i = 0; i < titles.length; i++) {
var str = titles[i];
var listItem = '<li class="navHighlight">'
+ '<a href="#">'
+ str
+ '</a>'
+ '<a href="#">'
+ '<img src="images/delete.png" class="deleteImage"/>'
+ '</a>'
+ '</li>';
$('.accountSelectNav').append(listItem);
}
Now, if I want to remove this <li> I click the delete image found inside our <li>. What delete image you say? Look at the html I added again. You will see I add an <img> tag in there.
Now delete like so:
$("body").on("click", ".deleteImage", function (e) {
// grabs the text value of my li, which I want to remove
var removeTitle = $(this).closest('li').find('a').text();
// runs through my titles array and returns an array without the value above
titles = jQuery.grep(titles, function (value) {
return value != removeTitle;
});
});
Then I simply place the new array inside my cookie once again. Like this:
$.cookie('titles', JSON.stringify(titles));
And finally I remove the tab like this:
removeTab(this);
function removeTab(del) {
$(del).closest('li').remove();
}
Yay, I'm done. So now, if anyone has a more elegant way of accomplishing this I'm listening. I have no doubt there's a better way, javascript/jQuery isn't even close to my strong point.

Here I have a code that create a sidebar:
var side_bar_html = "<a href='javascript:google.maps.event.trigger(gmarkers[" + parseInt(gmarkers.length - 1) + "],\"click\");'>" + place.name + "</a><br>" + '<div class="raty" />' + "</br>";
$(side_bar_html).appendTo('#side_bar').filter('.raty').raty({
score : place.rating,
path : 'http://wbotelhos.com/raty/lib/img'
})
How I can create a function from this code to create a sidebar with function ...
So something like that:
function Create_a_sidebar_and_put_it_into_ID#sidebar () {
//for every marker to return html string
return "<div class='element'>"+place.name+"</br>"+place.rating+"</div>" + etc...
Becouse I have a problem with creating html, I dont know what to append where and I dont have contol over that
Is it possible?
If I'm understanding your question correctly, you're asking how you can take your first code block that creates a rating for a certain place, and refactor it so that you can arbitrarily create sidebars for places at will. So that's how I'll approach this answer.
As #Sime Vidas mentioned, you can start by taking the code that creates the sidebar itself and making that a function such as that below. I've modified the function a bit to take the javascript out of the href attribute (which is generally considered a bad practice) and replaced passing an html string into $.fn.init (which I've found steeply degrades performance) with using DOM methods to create elements. You also don't need the <br /> after your a element because divs by default are block elements.
function createSidebar(place) {
var $sidebarLink = $(document.createElement('a'));
var $raty = $(document.createElement('div'));
$sidebarLink.attr('href', '#').text(place.name).click(function(evt) {
evt.stopPropagation();
google.maps.events.trigger(gmarkers[parseInt(gmarkers.length - 1, 10)], 'click');
});
$raty.addClass('raty').raty({
score: place.rating,
path: 'http://wbotelhos.com/raty/lib/img'
});
return $([$sidebarLink, $raty]);
}
Now you can do things like
var $sidebar = $('#side_bar');
places.map(createSidebar).forEach(function($sidebarPart) {
$sidebar.append($sidebarPart);
});
Sorry if I'm off track with answering your question, but I think this is what you were asking. If not feel free to leave a comment and we can talk about it more!
My approach is not working here. I am on a Welcome Page of a SharePoint 2010 document set and have placed my script in a Content Editor Web Part CEWP. I've got a block of jquery/javascript using the following code. I can get one or the other set of values from two different blocks of code but not both. So it seems like my duplicating some of the lines of code in the tow queries causes things to clash but I am not sure what i can change to make both sets unique or what is clashing between the two. Any guidance greatly appreciated. I'm just going in circles right now. thanks -dave
I am using two blocks that look like this but differ at listName. Maybe the page can only support one of these?
$(document).ready(function () {
$().SPServices({
operation: "GetListItems",
async: false,
CAMLRowLimit: 2000,
listName: "Personnel Management",
completefunc: fnCallBack
});
});
function fnCallBack(xData, Status) {
var index = 0;
$documentListtable = $("#documentListtable");
//Navigate through the XML
$(xData.responseXML).find("z\\:row, row").each(function () {
//Get the values to a local variable
var _url = $(this).attr("ows_FileRef").split(";#")[1];
var _name = $(this).attr("ows_LinkFilename");
;
var _author = $(this).attr("ows_Editor").split(";#")[1];
var modifiedOn = $(this).attr("ows_Modified");
var _TrainingStatus = $(this).attr("ows_Training_x0020_Certificates");
//Create clone of the table row
var $row = $("#templates").find(".row-template").clone();
//Add values to the column based on the css class
$row.find(".DocumentName").html(_pdfLink);
$row.find(".Author").html(_author);
$row.find(".LastModifiedOn").html(modifiedOn);
$row.find(".TrainingStatus").html(_TrainingStatus);
//Change the style for even rows
if (index % 2 == 0) {
$row.addClass("jtable-row-even")
}
if (_TrainingStatus.indexOf("1001") !=-1)
{
index = index + 1;
//add the row to table
$documentListtable.append($row);
}

You can try adding both the SPServices calls inside one $(document).ready instead of having two $(document).ready blocks. There can be multiple $(document).ready in a page but your issue sounds like only one SPService call is triggered on page load.
I have problems for insert dynamic id into function of JavaScript the code:
$('#scroll-up1, #scroll-down1').bind({ ..............
In this example I need the function to take values of id I send across the function
$('#scroll-up+id, #scroll-down+id').bind({ ..............
The problem it´s the quotes as " or ' no works for me and I can´t use right for function works fine , this script let me scroll text ok but only problem with this because no let me send values right from id of function.
EDIT FOR ME FOR PUT ALL CODE : .....
PHP AND HTML CODE
<?php
$fil_comments=file("comments.txt");
for ($i=0;$i<sizeof($fil_comments);$i++)
{
$line=explode("~",$fil_comments[$i]);
if ($i%2==0)
{
$back=1;
}
else
{
$back=2;
}
?>
<li>
<div id="web_comment_<?php echo $back?>">
<div id="web_comment_name"><?php echo $line[0];?></div>
<div class="web_comment_texto" id="scroll<?php echo $i;?>"><?php echo $line[1];?></div>
<div class="web_comment_arrow" style="margin-left:260px;" id="scroll-down<?php echo $i;?>"><img src="imagenes/comments/arrow_up.png"></div>
<div class="web_comment_arrow" style="margin-left:288px;" id="scroll-up<?php echo $i;?>"><img src="imagenes/comments/arrow_down.png"></div>
</div>
</li>
<script>
scroll_diver(<?php echo $i;?>);
</script>
<?
}
?>
FUNCTION OF JAVASCRIPT CODE
<script type="text/javascript">
function scroll_diver(id)
{
$(function() {
var ele = $('#scroll'+id);
var speed = 30, scroll = 5, scrolling;
$('#scroll-up'+id).mouseenter(function() {
// Scroll the element up
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() - scroll );
}, speed);
});
$('#scroll-down'+id).mouseenter(function() {
// Scroll the element down
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() + scroll );
}, speed);
});
//var a='#scroll-up'+id;
//var b='#scroll-down'+id;
var a='#scroll-up'+id;
var b='#scroll-down'+id;
//$('a,b').bind({
//$('#scroll-up1, #scroll-down1').bind({
//$('#scroll-up'+id+',#scroll-down'+id)
/// THE PROBLEM HERE !!!
$('#scroll-up'+id+', #scroll-down '+id).bind({
click: function(e) {
// Prevent the default click action
e.preventDefault();
},
mouseleave: function() {
if (scrolling) {
window.clearInterval(scrolling);
scrolling = false;
}
}
});
});
}
</script>
Basically the problem it´s in the line of JavaScript function for send id, if you see the PHP code, I use bucle for for create scrolling tips with informations and in each I can scroll his content, for this I call function into the bucle with:
<script>
scroll_diver(<?php echo $i;?>);
</script>
But in this line no send right information for works ok, if I use out bucle for one specific id, works ok , with this works yes but scroll up and down crazy fast , and the controls no works fine.
Then you need to look at something like this:
$('#scroll-up' + id + ', #scroll-down' + id).bind({ ..............
As a commentor mentioned, jQuery selectors are simply strings. You can put them together as you see fit. In this case, I'm concatenating the id (which for simplest examples, I'm assuming is a number or other unique identifier) to the #scroll-up selector, so if your id was "1", you would end up with a string, effectively, that looks like:
'#scroll-up1, #scroll-down1'
after the string concatenation occurs.
Also, it might be worth noting that you'd probably get better bang for your buck if you simply gave both objects the same class, then inside your binding function, work out which item called and perform your scrolling appropriately.
So, if you had:
<div class="container">
<div id="scroll-up1" class="scroller"><!-- and code --></div>
<div id="scroll-down1" class="scroller"><!-- and code --></div>
</div>
then your javascript could look like this, avoiding the need for concatenation:
$('.container').on("mouseover",'.scroller', function(){
var thisId = $(this).attr("id");
if(thisId == "scroll-up1"){
// do your up-scroll
} else if(thisId == "scroll-down1") {
// do your down-scroll
}
});
Mind you, that uses .on(), which is preferred over .bind(), but the idea is to handle it based on a common class, rather than having to modify your selector every time you go to bind your event handler for those items.
Recommended solution: use CLASS NAMES for COMMON FEATURES
$('.scroll-up, .scroll-down').bind({
or even:
$('.scroll').bind({
var id = 38;
$('#scroll-up' + id + ', #scroll-down' + id).bind({ ..............
