Javascript - Dynamically added tabs not seen as tabs in Kendo panelbar - javascript

Ok, first off I read in an encrypted file as my DataSource, which is then converted to an XML String.
The data displays properly in my grids, except that the panels which are dynamically added to the panelbar does not seem to act as such as seen in this fiddle.
They are added to:
<ul id='panelbar'>
<li id='patDet' class='k-state-active'>
<span class='k-link k-state-selected'><input type='checkbox' id='cPatientDetails' /><label for='cPatientDetails'><a href='#' id='cbSelect'></a>Patient Detail</label></span>
<div id='patTab'></div>
</li>
</ul>
like so:
$("<li id = '"+ liID +"' class='k-item k-state-default' role='menuitem' aria-expanded='false' aria-hidden='true'><span class='k-link k-header'><input type='checkbox' id='c" + x + "' class='cbSelect' /><label for='c" + x + "'><a href='#' id='cbSelect''></a>" + liTitle + "</label></span></li>").appendTo("#panelbar");
$("<div id = 'gridGenerate" + x + "' width='400px;' aria-hidden='true'></div>").appendTo("#" + liID);
The reason for the span and link is so that styling can be used on my checkbox which can be found in this fiddle.
At first I used a hard coded DataSource, which worked perfectly, but when I switched over to fetching the data using a request, where all the data displays as it should, except for the panelbar.
This is what it looks like:
when only the first tab should be open. I created the panelbar like so:
$("#panelbar").kendoPanelBar(
{
expandMode: "single"
});
EDIT
I've made it now that the panelbar and grids are only created once the data is retreived and converted, but the issue remains.
Any idea why this is happening?

When KendoUI adds a tab, it does much more than just adding HTML tags. That's why you have methods for adding tabs on demand.
Instead of adding the HTML by hand try using:
var panelbar = $("#panelbar").data("kendoPanelBar");
panelbar.append([
{
text: "<label for='c" + x + "'>" +
"<a href='#' id='cbSelect''></a>" +
"" + liTitle + "" +
"</label>",
encoded: false,
content: "<div>text</div>"
}
]);

Answer:
It seems like when I ask a question, it helps me to find the answer. Just found it.
I created the panelbar before adding the extra panels, so I just moved the:
$("#panelbar").kendoPanelBar(
{
expandMode: "single"
});
to the end of my method. The all the content is added, then I create the panelbar.

Dynamically add array contents as new elements - JQuery

edit: Problem solved! I was modifying the page before it was loaded so the script didn't actually do anything. I fixed it now and it works. Thanks for the help, I'll have to chalk this one up to being new to jQuery and it's weirdness.
Long story short I'm trying to make a webpage that dynamically takes Article titles, thumbnail images, descriptions, and links to them, and creates a nicely formatted list on the page. I'm trying to accomplish this in jQuery and HTML5.
Here is the sample data that I'll be using to dynamically populate the page. For now formatting isn't important as I can do that later after it works at all.
<script>
var newsTitles = ["If It Ain't Broke, Fix It Anyways"];
var newsPics = ["images/thumbnail_small.png"];
var newsDescs = ["August 14th 2015<br/><b>If It Ain't Broke</b><br/>Author: Gill Yurick<br/><br/> Sometimes, a solution isn't the only one. So how do we justify changes to systems that don't need to be fixed or changed? I explore various systems from other successful card games and how their approaches to issues (be they successes or failures in the eyes of the deisgners) can help us create EC."];
var newsLinks = ["it_aint_broke-gill_popson.html"];
var newsIndex = 0;
var newsMax = 1;
The section of code where I'm trying to use the contents of the arrays above to dynamically fill elements.
<td style="height:500px;width:480px;background-color:#FFF7D7;padding:20px" colspan=2 id="article">
<h1>Articles</h1>
<!-- the column for each news peice add an element with the thumbnail, the title and teh desc -->
<script>
for(i = 0; i < newsMax; i++) {
$("#articleList").append("<h3 href="" newsLinks[i] + "">" + newsTitles[i] + "</h3>", "<img src=""newsPics[i] + "">","<p>" + newsDesc[i] + "</p>", ); $("div").append("hello");
}
</script>
<div id="articleList">
HELLO
</div>
</td>
Here is what it ends up looking like, I can post more info if needed as I am aware this may not be clear enough to fully explain my problem but I am unable to determine that. Thank you in advance.
try this
for(i = 0; i < newsMax; i++) {
$("#articleList").append("<h3 href=""+ newsLinks[i] + "">" + newsTitles[i] + "</h3>, <img src=""+newsPics[i] + "">, <p>" + newsDescs[i] + "</p>" ); $("div").append("hello");
}
Concatation issue + typo for newsDescs
The following string is invalid html and is missing a +
"<h3 href="" newsLinks[i] + "">"
You need to use proper quotes for html attributes, not &quote;
Try
"<h3 href='" + newsLinks[i] + "'>"
OR
"<h3 href=\"" + newsLinks[i] + "\">" // `\` used to escape same type quote
Personally I prefer opening/closing html strings with single quotes but either will work
Note tht you should be getting a syntax error thrown in dev tools console which would have helped you locate problems
for(i = 0; i < newsMax; i++) {
$("#articleList").append("<h3 href='" + newsLinks[i] + "'>" + newsTitles[i] + "</h3>");
$("#articleList").append("<img src='" + newsPics[i] + "'>","<p>" + newsDesc[i] + "</p>" );
}

Displaying a Jquery image list

I'm having a problem with the JQuery imagelist. When opening the page for the first time, the list displays correct, the image is shown, title is shown...
Pressing the back button and re-opening the page gives a normal list, no longer the jquery listview?
I'm using a DIV element in my page like this:
<div id="dataDiv">
<ul data-role='listview' id='listing' data-theme='c'>
</ul>
</div>
This gets filled with information retrieved from an api call:
function listApiInfo() {
clearDataDiv();
var parsed = makeApiCallGet("http://someSite/SomeApi");
i = 0;
for (i; i < 15; i++) {
$("#listing").append("<li>"
+ "<img src='" + imageUrl + "' alt='img' class='ui-li-thumb' />"
+ "<h1>" + parsed[i].info + "</h1>"
+ '</a></li>'
);
}
}
on loading the div, i make sure it's an empty list item:
function clearDataDiv() {
$("#dataDiv").html(
"<ul id='listing' data-role='listview' data-theme='c'></ul>");
}
Edit: As suggested by Wibble in the comments, i did look at the cache as the problem.
Giving the div the following option solved the problem:
<div id="dataDiv" onblur='window.location.reload()'>
<ul data-role='listview' id='listing' data-theme='c'>
</ul>
</div>
I'm still not sure if this is the most elegant solution though, it gives a blank screen for a split second.

Wrap each list array in a Tag

I am trying to get each Post lists wrapped in the href so it can be clicked on. Basically when I try to click on each Posts, it does not work until I hover my mouse close to the top of each posts before it works.
Below is my code and also an image of what I mean:
JS:
function getPosts(data) {
var $output = $('<ul class="posts" data-role="listview" data-filter="true">')
$.each(data.posts,function(i, val) {
$('<li><a href="#devotionpost" onclick="showPost(' + val.id + ')"</a>').append([$("<h3>", {html: val.title}),$("<p>", {html: val.excerpt})]).appendTo($output);
if ( i == 3 ) return false;
// return (postlimit-- > 1);
});
$('#postlist').empty().append($output);
}
function showPost(id) {
$('#mypost').html('<span class="img_spin">Loading post...</span>');
$.getJSON('http://howtodeployit.com/category/daily-devotion/?json=get_post&post_id=' + id + '&callback=?', function(data) {
var posts='';
posts += '<h3>' + data.post.title + '</h3>';
posts += data.post.content;
$('#mypost').html(posts);
});
}
Image:
If you look at the image, when i hover my mouse close to the top edge of the Post, then the URL at the bottom shows and that works but any where else does not work.
From looking at the Chrome Elements tab in this demo the JavaScript is generating invalid HTML because of mismatched closing elements.
Using an example posts of var posts = { "posts" : [ {"id":"1", "title":"lorem", "excerpt":"foo"}, {"id":"2", "title":"ipsum", "excerpt":"bar"} ] }
This '<li><a href="#devotionpost" onclick="showPost(' + val.id + ')"</a>' is resulting in the broken first child of the following <li>:
<li>
<a href="#devotionpost" onclick="showPost(1)" < a></a>
<h3>lorem</h3>
<p>foo</p>
</li>
Depending on exactly what you want to wrap in the anchor element, you could just build the post <li> like in this updated demo or see code below:
$.each(data.posts,function(i, val) {
$output.append('<li><h3>' + val.title + '</h3><p>' + val.excerpt + '</p></li>');
});
Or if you want to have a little less string concatenation, you could use .wrapInner()
$.each(data.posts,function(i, val) {
var $post = $('<li><h3>' + val.title + '</h3><p>' + val.excerpt + '</p></li>');
$post.wrapInner('');
$output.append($post);
});
Or keeping your .append() approach:
$.each(data.posts,function(i, val) {
var $post = $('<li/>').append([$("<h3>", {html: val.title}),$("<p>", {html: val.excerpt})]).wrapInner('');
$output.append($post);
});
Note: The string concatenation approach, combined with a single .append() is the best performing code.
By the looks of it, your lists are floating. You should use a clearfix technique to make "A" element box include the list. You also should know that by standard "A" elements are not allowed to contain block elements and as far as internet explorer 9 (didn't check in 10 or 11) "A" will not work the way you intended.
Possible workaround:
<div style="position:relative">
<ul>
<li></li>
<ul>
<a style="position:absolute;display:block;top:0;bottom:0;left:0:right:0;" href="#"></a>
<div>

Building html tags on Javascript in ruby on rails

I'm creating my html tags on my Javascript because of some logic, but the expected result is not being displayed. I'm trying to get all checked checkboxes and display their names. I can pull the names and the checked checkboxes. But it is no rendering correctly. Here is my code:
var amenities = <%= #amenities_json.html_safe %>;
var appendAmenitiesAndFeatures= "<p class='p-tab-title3'>Amenities</p><table class='table-amenities-and-features'><tbody><tr>";
for(var i=0; i<amenitiesChecked.length;i++)
{
$.each(amenities, function(index, amenity){
if(amenity.id == amenitiesChecked[i])
{
appendAmenitiesAndFeatures += "<td><p class='p-tab-subtitle2><span> </span>" + amenity.name + "</p></td>";
}
});
}
appendAmenitiesAndFeatures += "</tr></tbody></table>";
$("#dv-amenities-and-features").html(appendAmenitiesAndFeatures);
When I check 3 checkboxes and alert their names, I can see the string of html tags being build properly. I can see 3 sets of tds in my alert. But when the page is being rendered. It only displays one. I really don't know why. I'm appending to a div and build my table using .html. Any ideas?
hum.... You miss a '
replace your line with this:
appendAmenitiesAndFeatures += "<td><p class='p-tab-subtitle2'><span> </span>" + amenity.name + "</p></td>";

Divs with same id error

<div id="tagTree1" class="span-6 border" style='width:280px;height:400px;overflow:auto;float:left;margin:10px; '>
<a class="tabheader" style="font-size:large">Data Type</a><br />
<div class="pane">Refine search by Data Type</div>
</div>
Above div(tagTree1) is present in a division ad.
<div id="newtagTree1" class="span-6 border" style='width:200px;height:400px;overflow:auto;float:left'>
<a class="tabheader"><strong>Geographic Location</strong></a><br />
<div class="pane"><strong>Refine search by geographic location</strong></div>
</div>
newTagTree1 division is present in another division search. But both have the same functionality to generate children divisions within them, which is written in a js file. All the children division generated dynamically in js file. Both of them uses same function to generate children divs. I am facing problem when i am using them in same page. If one works fine then the other doesn't. Can any one say me about the mistake i am doing in this?
Thanks in advance.
$.getJSON('/api/TagsApi/Children?id=800002', function (data) {
//$(tagDiv).empty();
$.each(data, function (i, item) {
$("#tagTree1").append(tagTabBuilder(item));
});
$("#tagTree1").tabs("#tagTree1 div.pane", { api: true, tabs: 'a', effect: 'slide', onClick: buildChildren, initialIndex: 0 });
});
function tagTabBuilder(tagData) {
var str = "<input type='checkbox' name='tagchkbox[]' value='" + tagData.ID + "' onClick='startQuery()' /><a class='tabheader '>" + tagData.NAME;
if (tagData.count == 0) {
str += " (<span class='el_count' id='t" + tagData.ID + "'>" + tagData.count + "</span>)" + "</a><br/>";
} else {
str += " (<span class='el_count' id='t" + tagData.ID + "'><strong>" + tagData.count + "</strong></span>)" + "</a><br/>";
}
str += "<div id='tid-" + tagData.ID + "' class='pane tag'><!--Loading subtags. . .<img src='/assets/modules/gaiaModule/shared/images/load-small.gif' />--></div>";
return str;
}
My guess would be that when they generate child divs, they're generating them with the same ID scheme. Thus, either of them can generate child divs just fine by itself, but when both of them are included, there is ID collision. The answer is to modify the child generation code to, for example, include the id of the parent div as the first portion of the id of the child div.
Alternately, if you dont' need them for other portions of the javascript, leave the child div ids out entirely. In general, I find that it's better to avoid the id attribute in generated nodes, and instead use classes or the like.
