Please find the below snippet. Can any one explain above functionality for the data-sly-test. How it will work condition here for image??
<div class="spon-image-container col-12 col-md-4">
<sly data-sly-test="${properties.fileReference}">
<img class="spon-_image" src="${properties.fileReference}"/>
</sly>
</div>
There are a few things to mention here. The gist of the code snippet is, that the <img> tag will only be rendered if {$properties.fileReference} is not empty.
Be aware, there is no sanity check involved here. data-sly-test won't check if the referenced file exists etc.
So assume that ${properties.fileReference} equals /content/dam/myImage.png. Then the resulting HTML would like this:
<div class="spon-image-container col-12 col-md-4">
<img class="spon-_image" src="/content/dam/myImage.png"/>
</div>
On the other hand, if the ${properties.fileReference} is empty (or null) you get the following HTML:
<div class="spon-image-container col-12 col-md-4">
</div>
Depending on your HTML/CSS/JS you might not want that to happen. So you could improve your code to include the data-sly-test statement in the <div> tag:
<div class="spon-image-container col-12 col-md-4" data-sly-test="${properties.fileReference}">
<img class="spon-_image" src="${properties.fileReference}"/>
</div>
This way, the <div> is only rendered, if a fileReference is set. But even if you still want the <div> to appear, your code can be improved by removing the <sly> element and adding the data-sly-test to the <img> tag:
<div class="spon-image-container col-12 col-md-4">
<img class="spon-_image"
src="${properties.fileReference}"
data-sly-test="${properties.fileReference}"/>
</div>
As mentioned in the specification, data-sly-test:
Keeps or removes the element depending on the attribute value.
For your case if fileReferece property evaluates to true (not null, not empty), it will render:
<div class="spon-image-container col-12 col-md-4">
<img class="spon-_image" src="....."/>
</div>
Note that the sly tag unwraps/removes itself, it's actually unnecessary here as the data-sly-test attribute could be moved to the img.
If fileReference evaluates to false, it will render:
<div class="spon-image-container col-12 col-md-4">
</div>
It basically checks if the current resource properties(i.e component properties) contain fileRefernce then it will add an image tag.

I masked(mask-extension) a couple of plug-ins. When the image is generated in the template, it is always wrapped in following divs:
<div id="c63" class="frame frame-default frame-type-image frame-layout-0">
<div class="ce-image ce-center ce-above">
<div class="ce-gallery" data-ce-columns="1" data-ce-images="1">
<div class="ce-outer">
<div class="ce-inner">
<div class="ce-row">
<div class="ce-column">
<figure class="image"><img class="image-embed-item"
src="fileadmin/user_upload/bla" width="975"
height="678" alt=""></figure>
</div>
</div>
</div>
</div>
</div>
</div>
Is there any way to remove all those wrappers? I simply want to have the image.
Sidenotes:
1. f:image does not work, I cannot access the proper uid for it to show. (This is perhaps an issue with mask)
2. I cannot find the tt_content.stdWrap.innerWrap > in my typoScript, as I do not know where mask puts it. It is neither in the netup.ts nor in the NewContentElementWizard.ts
You need to overwrite the fluid_styled_content partial in Resources/Private/Partials/Media/Gallery.html.
How to overwrite, you can read here: https://docs.typo3.org/typo3cms/extensions/fluid_styled_content/8.7/Configuration/OverridingFluidTemplates/
I am using ng-flow in my app, is there any way to limit the number of files for upload?
A code sample:
<div class="thumbnail" ng-show="$flow.files.length">
<img flow-img="$flow.files[0]" />
</div>
<div>
Select image
Change
<a href="#" class="btn btn-danger" ng-show="$flow.files.length"
ng-click="$flow.cancel()">
Remove
</a>
</div>
The attribute flow-file-added is expecting a boolean value.
You can put all your conditions in there.
$flow.files.length returns the number a files you have already added
For example:
<div flow-init flow-files-submitted="$flow.upload()" flow-file-added="$flow.files.length<3"></div>
I have some slightly awkward markup and need to reference some elements from a separate container, and prevent those elements from appearing under the parent in their hierarchy. How can I do this?
Here's my (simplified) markup:
<body itemscope itemtype='https://schema.org/AboutPage'>
<div itemscope itemtype="https://schema.org/ProfessionalService">
<ul>
<li><img id="photo-emp1" itemprop="image" src="..."/></li>
<li><img id="photo-emp2" itemprop="image" src="..."/></li>
<li><img id="photo-emp3" itemprop="image" src="..."/></li>
<li><img id="photo-emp4" itemprop="image" src="..."/></li>
</ul>
<div id="tab-emp1" itemprop="employee" itemscope itemtype="https://schema.org/Person"
itemref="photo-emp1">
<h1 itemprop="name">John Doe</h1>
<h2 itemprop="jobTitle">Vice President, Finance</h2>
<div itemprop="description">John is...</div>
</div>
<div id="tab-emp2" itemprop="employee" itemscope itemtype="https://schema.org/Person"
itemref="photo-emp2">
<h1 itemprop="name">Jane Roe</h1>
<h2 itemprop="jobTitle">Vice President, Operations</h2>
<div itemprop="description">Jane is...</div>
</div>
...
</div>
</body>
The structure is required for a tab control, so I can't rearrange the markup.
The itemref attribute on the Person correctly drags the image 'under' the https://schema.org/Person node.
However, the image elements ALSO appear as properties under the https://schema.org/ProfessionalService node, which is not correct or desired.
How can I keep the image elements in their current location, reference them under Person, but prevent them from appearing under ProfessionalService?
Just add the itemscope attribute to the ul element. You'll get an extra, disconnected, item, but the images will no longer be part of the ProfessionalService item.
I'm trying to learn bootstrap on my site but the form is just too narrow that I cannot change the width by changing the text field's cols.
see the page:
http://saslab.org/mycontact.php
and this page:
http://saslab.org/testme.html
could some one educate me on this?
thank you!
John
do it like this:
<div class="row">
<div class="span4">
<p>Name</p> <input type="text" name="name">
</div>
<div class="span4">
<p>Email</p> <input type="text" name="email">
</div>
<div class="span4">
<p>Phone</p> <input type="text" name="phone">
</div>
</div>
wrap the p tag and input with span
You have a line in your source: <div class="container marketing">. Upon further inspection, your 'marketing' class has the attribute text-align:center. This means all of your form will be centered because the div that contains it has that class. This is why your form is narrow.
Specifically, you have a file called mycontact.php and here's what you have for the CSS that applies:
.marketing .span12 {
text-align: center;
}
well, i guess it is Bootstrap's default css that causes the narrowing. in the following links, you can see the contrast

I've my markups as
<div id="home" class="current">
<div class="header">iScroll</div>
<div class="wrapper">
<div id="scroller">
<ul id="thelist" class="plastic"><!-- li items --></ul>
</div>
</div>
<div class="footer">Footer</div>
</div>
<!-- Events Details -->
<div id="events">
<div class="header">iScroll</div>
<div class="wrapper">
<div id="scroller"> <!-- stuffsss --></div>
</div>
<div class="footer">Footer</div>
</div>
For iScroll (http://cubiq.org/iscroll) to work, I need the #scroller as ID (as per the javascript Code I'm using to initialize iScroll.
//for iScroll
var myScroll = new iScroll('scroller', {desktopCompatibility:true});
// Load iScroll when DOM content is ready.
document.addEventListener('DOMContentLoaded', loaded, false);
But since I can't have two different elements with the same ID (please notice I've got two elements with same id scroller in my markup above), some conflicts are there and the iScroll isn't working properly.
I want to be able to implement the iScroll on the markup by changing the id as classes. I tried to change them into classes and see if it works but I couldnt get it right.
Can anyone help me change the codes so that it works by implementing classes instead of the the id??
Rob is right, but you can change your code to scroller classes as you said.
Then initialise your scrollers within unique wrappers like this:
var scroll1, scroll2;
function loaded() {
scroll1 = new iScroll('wrapper1');
scroll2 = new iScroll('wrapper2');
}
I'm not totally clear on what you are trying to achieve but if you want two parts of your page to scroll I would suggest changing the IDs to be unique and instantiate two iScrolls with the different IDs.
I am sure you have figured it out, but for other users still struggling with similar layout (multiple scrollers) and want to make them work. Here is the answer from other thread
https://stackoverflow.com/a/7584694/1232232
but for this to work you need to assign ID's to your classed (div containers)
like
<div id="home" class="current">
<div class="header">iScroll</div>
<div id="wrapper-1" class="scrollable">
<div class="scroller">
<ul class="thelist" class="plastic"><!-- li items --></ul>
</div>
</div>
<div class="footer">Footer</div>
</div>
<div id="home2" class="current">
<div class="header">iScroll</div>
<div id="wrapper-1" class="scrollable">
<div class="scroller">
<ul class="thelist" class="plastic"><!-- li items --></ul>
</div>
</div>
<div class="footer">Footer</div>
</div>
Note: Remember not to assign same ID to multiple elements, always use classes for that purpose.
