I am currently trying to find a way to assign a certain class name for an element.
I'm using a bootstrap framework to created a tabbed element. This element runs a for loop to make tabs and tab content for each item in a specific folder. Because of the for loop, each tab and content box has the same class. But, for this element to look right when the page loads, it should have a default tab (like the first one) that is displayed. The default tabs and content boxes need to have "active" and "active in" in their respective class names.
My question is since the for loop makes them all the same, how can I code this to make the first tab and content box "active" and leave the rest as is? Also, would it be possible to use an if else statement. I'm not experienced yet with PHP, so I might not understand a solution using it.
I would like to do this inline, like say (href='stuff' class='inline stuff here' / maybe class="inline if else statement") I know it may not be the best method, but i would like to try that first. If I must do it a different way, I will try.
<ul class="nav nav-tabs">
#foreach(var sections in Links)
{
<li>#sections.title<li>
}
<div class="tab-content">
#foreach(var content in Links)
{
<div class="tab-pane fade" id="#">
#content.bodytext
</div>
}
What is the best method to make the code assign "active" to the first tab and "active in" to the first tab content while leaving the rest to be normal so the first tab and content will load by default on the page?
Thank you so much in advance for the help!

I am looking for a way to go from my navigational links using voice-over accessibility to jump to the internal part of the page that link I connected to.
For example:
I have a list of links on my left-hand side. One is for Forms. When I click on "Forms" my list of forms will populate to the right of that panel, and then if you click on a specific form, that Form will appear to the right of that panel. The page contains 3 panels with Navigation on the left, list in the middle, Form on the right.
Right now if I click on the Form link, I have to tab through my entire nav panel to get to the newly opened Forms list.
Are there some ARIA elements I am missing that will help tab directly into my Forms List from the Forms link?
There are two simple ways to do this.
Note that neither of the following ways need any aria to work, the aria in the following examples is purely for best practices when adding sections and headings to a page.
Option 1 - anchors
The first is using anchors pointing to ids on the page.
in your side bar
forms
main page section
<section aria-labelledby="forms">
<h2 id="forms">Forms</h2>
<!---your forms --->
</section>
Notice how I gave the page content a heading (pick an appropriate heading level) and then labelled the section with aria-labelledby. None of this is required to make this method work but it is a good practice.
The only thing you need to do is to make sure your href matches the ID of the heading.
However given that you are populating the forms on the right side of the page (I am assuming with an AJAX call) you may want to manually manage focus with JavaScript....
Option 2 - Use JavaScript and .focus()
If you are using JavaScript it is a similar principle, give the section heading an ID, but this time once the forms list has loaded set focus on the list heading.
html
<!--your link in the menu -->
forms
<!--section on the page, I omitted the aria here for clarity / simplicity but it is still needed-->
<section>
<h2 id="forms" tabindex="-1">Forms</h2>
</section>
JavaScript
// start: however you have this implemented at the moment
const formsLink = document.querySelector("#getForms");
formsLink.addEventListener('click', function(e){
e.preventDefault();
get('yourURL').then((data) => {
// populate the list
list.update(data);
// end: however you have this implemented at the moment
// once the list is populated set focus on the heading (last thing to do after everything else is done)
document.querySelector('#forms').focus();
});
});
Notice how in this example the <h2> has a tabindex="-1".
We need this to allow programmatic focus. We use -1 so we can focus the heading via JavaScript but it does not get added to the page focus order (so you can't access it with Tab).
I'm using Vimium on Firefox and Chrome and it helps me a lot https://github.com/philc/vimium
I noticed that some divs can be clicked and I found that class='demo-button' is one of them
<div class='demo-button'>demo-button</div>
<div class='demobutton'>demobutton</div>
<div class='demobuttonnn'>demobuttonn</div>
<div class='demobutto'>demobutto</div>
Here is a screenshot of Vimium links https://jsfiddle.net/qnvujfs6/
As you can see, only the last div demobutto can not be clicked using Vimium. I tried to search Vimium source for demo-button or demobutton but no results.
Does anyone have an idea why there is a difference between this demo button div-s ?
I want to be able to click on some generated elements using bootstrap plugins, for example Bootstrap Toggle. Here is code for two toggles, but only second one can be clicked because it contains demo-button class
https://codepen.io/duleorlovic/pen/VqWaEg
The first three are clickable because the class attribute contains the word "button" (See source).
For usability purposes it preferred to simply use the elements that are meant to do that job. For instance anchors (<a>) and buttons (<button>).
But if that is not possible (which seems to be the case here) you can also add the role attribute to the element. Elements with the attribute role with one of the following values will also be considered clickable:
button
tab
link
checkbox
menuitem
menuitemcheckbox
menuitemradio
(Source)
So if your div elements represent check boxes, your code would look like this:
<div class="demo-button" role="checkbox">demo-button</div>
<div class="demobutton" role="checkbox">demobutton</div>
<div class="demobuttonnn" role="checkbox">demobuttonn</div>
<div class="demobutto" role="checkbox">demobutto</div>
In this case you are not depending on specific class names, which are by the extension considered "as unreliable".
Hi all,
I've been working on a set of Razor templates that is either Site Editable with the Experience Manager and at the same time is fully responsive for several screenwidths with the Twitter bootstrap. As a result, I need to dynamically manipulate the DOM output based on what the Experience Manager editor adds or deletes but still maintain the responsive design. Part of this construction is adhering to the rules the twitter bootstrap dictates.
The twitter bootstrap allows for excellent responsive design by introducing dynamically calculated div widths using classes. A <div class="span12> uses the entire width of the wrapper, for example. A "span6" effectively uses half, with a certain margin calculated as well to allow for another div with "span6". However, this only works if the preceding class is called <div class="row-fluid">,and as long as the span<numbers> actually add up to exactly 12. The problem arises when I need to close the <div class="row-fluid"> when this number is actually reached.
To clarify: it has to output like this
<div class="row-fluid">
<div class="span6">..code</div>
<div class="span4">..code</div>
<div class="span2">..code</div>
</div>
The <div class="span[#]"> are rendered with a component template, in order to allow for multiple components within the <div class="row-fluid>, which the Page Template renders.
However, from a component template level I cannot seem to retrieve the actual amount of components of this template actually exist on the Page itself. I calculate the width of the component used based on a schema option of the component itself. I use the following Component Template code to render it correctly:
#{
var spanClass = String.Empty;
if (Fields.HasField("component_width") && Fields.component_width != null) {
if (Fields.component_width.ToLower() == "full") {
spanClass = "span12";
} else if (Fields.component_width.ToLower() == "half") {
spanClass = "span6";
} else if (Fields.component_width == "40%") {
spanClass = "span5";
} else if (Fields.component_width == "35%") {
spanClass = "span4";
} else if (Fields.component_width == "25%") {
spanClass = "span3";
}
}
}
<div class="#spanClass">...code
To get to my question: I need to be able to close the <row-fluid> div if the number 12 has been reached. So if one component with the options 'Full' (width) is selected, the following output code needs to appear:
<div class="row-fluid">
<div class="span12">..code</div>
</div>
If there are two components on the page with the option "half" are selected, it must allow
<div class="row-fluid">
<div class="span6">..code</div>
<div class="span6">..code</div>
</div>
mind the closing div on the end. Is there some way I can reach the variable i created on the Component Template var spanClass = String.Empty; from Page Template? Something like:
#foreach (var cp in GetComponentPresentationsByTemplate("XM_Generic Content")) {
#if (cp.Component.spanClass == "span6") {
<div class="row-fluid">
#cp.RenderComponentPresentation()
#if (cp.Index == 1) {
</div>
}
}
}
I'm still getting to know Razor templates, the practicalities of Responsive design and ofcourse StackOverflow. Chances are that I completely missed something, made dumb errors in my code of just asked a silly question. By all means, let me know.
The package is not shared between template runtimes, so this behavior is normal (not being able to see variables set in one template from a different instance).
There are ways around this, but you should consider that perhaps there is a good reason why Tridion chose to isolate the template execution.
See here for one of the ways to go around this.
Standard techniques using the ContextVariables dictionary don't allow you to set something in the CT and access it from the PT. Effectively, each time a Component is rendered, the render context gets a fresh copy of the variables from the page render context. Writing back to them, therefore isn't effective. There is a technique that gets round this, which is described in detail on tridion-practice. As already noted, resorting to these kinds of techniques shouldn't be your first option, but sometimes you need to.
Currently, its seems, the user is defining the width position in the component field. I think, its quite typical, but if you create 5 Component Template which will call a same Razor TBB, and also define, a parameter schema on component Template where can set the width of component then afterwards you can easily call these different CTs in the page template.
I'm writing an application, a reporter with heirarchy of folders and files, in the lower heirarchy level there are 2 types of reports: the simple one is a flat (non link) report that being presented as a single simple line.
the second type is a link with a general description in the header and if you press the link you get a full report.
example: if I run a telnet command, I will see the command in the header and if I want to see the entire session with the device I will press the link and it will be presented.
My problem is that most of this lined-files are small but the OS reserve a minimum space for every file so I loss alot of disk space for nothing.
The solution I want to implement is a "dummy" links, which will be presented and will behave like a regular links but actually will be stored in the same file like their "parent" (probably with alot of other links like them).
The solutions I saw so far are only for "jumping" inside a page but this is not what I'm looking for, I want it to be presented like a seperated file and I dont want the "parent" file to present this information at all (the only way to see it will be by pressing the link and even then it will present only this information and not the other file content).
any idea guys?
To link to a specific part in a web page, place an anchor link where you want the user to go to when they click a link with:
<a name="anchor"></a>
and link to it with:
Click here
You can replace "anchor" with a more descriptive name if needed.
To hide/show a div (the following code is untested, but should work)
JQuery solution (If you're using JQuery):
function toggle(divname) {
$(divname).toggle();
}
The corresponding HTML:
<div id="content">some content</div>
<a onclick="toggle('content')">Click here to show/hide the content div!</a>
Non-JQuery Solution:
function toggle(divname) {
var adiv = document.getElementById(divname);
if (adiv.style.display === 'block' || adiv.style.display === '') {
adiv.style.display = 'none';
} else {
adiv.style.display = 'block'
}
}
The HTML:
<div style="display:hidden" id="content">Content</div>
<a onclick="toggle('content')">Click here to show/hide the content div!</a>
I have an array of 2000 items, that I need to display in html - each of the items is placed into a div. Now each of the items can have 6 links to click on for further action. Here is how a single item currently looks:
<div class='b'>
<div class='r'>
<span id='l1' onclick='doSomething(itemId, linkId);'>1</span>
<span id='l2' onclick='doSomething(itemId, linkId);'>2</span>
<span id='l3' onclick='doSomething(itemId, linkId);'>3</span>
<span id='l4' onclick='doSomething(itemId, linkId);'>4</span>
<span id='l5' onclick='doSomething(itemId, linkId);'>5</span>
<span id='l6' onclick='doSomething(itemId, linkId);'>6</span>
</div>
<div class='c'>
some item text
</div>
</div>
Now the problem is with the performance. I am using innerHTML to set the items into a master div on the page. The more html my "single item" contains the longer the DOM takes to add it. I am now trying to reduce the HTML to make it small as possible. Is there a way to render the span's differently without me having to use a single span for each of them? Maybe using jQuery?
First thing you should be doing is attaching the onclick event to the DIV via jQuery or some other framework and let it bubble down so that you can use doSomething to cover all cases and depending on which element you clicked on, you could extract the item ID and link ID. Also do the spans really need IDs? I don't know based on your sample code. Also, maybe instead of loading the link and item IDs on page load, get them via AJAX on a as you need them basis.
My two cents while eating salad for lunch,
nickyt
Update off the top of my head for vikasde . Syntax of this might not be entirely correct. I'm on lunch break.
$(".b").bind( // the class of your div, use an ID , e.g. #someID if you have more than one element with class b
"click",
function(e) { // e is the event object
// do something with $(e.target), like check if it's one of your links and then do something with it.
}
);
If you set the InnerHtml property of a node, the DOM has to interpret your HTML text and convert it into nodes. Essentially, you're running a language interpreter here. More text, more processing time. I suspect (but am not sure) that it would be faster to create actual DOM element nodes, with all requisite nesting of contents, and hook those to the containing node. Your "InnerHTML" solution is doing the same thing under the covers but also the additional work of making sense of your text.
I also second the suggestion of someone else who said it might be more economical to build all this content on the server rather than in the client via JS.
Finally, I think you can eliminate much of the content of your spans. You don't need an ID, you don't need arguments in your onclick(). Call a JS function which will figure out which node it's called from, go up one node to find the containing div and perhaps loop down the contained nodes and/or look at the text to figure out which item within a div it should be responding to. You can make the onclick handler do a whole lot of work - this work only gets done once, at mouse click time, and will not be multiplied by 2000x something. It will not take a perceptible amount of user time.
John Resig wrote a blog on documentDragments http://ejohn.org/blog/dom-documentfragments/
My suggestion is to create a documentDragment for each row and append that to the DOM as you create it. A timeout wrapping each appendChild may help if there is any hanging from the browser
function addRow(row) {
var fragment = document.createDocumentFragment();
var div = document.createElement('div');
div.addAttribute('class', 'b');
fragment.appendChild(div);
div.innerHtml = "<div>what ever you want in each row</div>";
// setting a timeout of zero will allow the browser to intersperse the action of attaching to the dom with other things so that the delay isn't so noticable
window.setTimeout(function() {
document.body.appendChild(div);
}, 0);
};
hope that helps
One other problem is that there's too much stuff on the page for your browser to handle gracefully. I'm not sure if the page's design permits this, but how about putting those 2000 lines into a DIV with a fixed size and overflow: auto so the user gets a scrollable window in the page?
It's not what I'd prefer as a user, but if it fixes the cursor weirdness it might be an acceptable workaround.
Yet Another Solution
...to the "too much stuff on the page" problem:
(please let me know when you get sick and tired of these suggestions!)
If you have the option of using an embedded object, say a Java Applet (my personal preference but most people won't touch it) or JavaFX or Flash or Silverlight or...
then you could display all that funky data in that technology, embedded into your browser page. The contents of the page wouldn't be any of the browser's business and hence it wouldn't choke up on you.
Apart from the load time for Java or whatever, this could be transparent and invisible to the user, i.e. it's (almost) possible to do this so the text appears to be displayed on the page just as if it were directly in the HTML.
