I want to transclude html in a component, similar on how angularjs does with transclude:true (directives).
Suppose I have this html
<div wicket:id="myComponent> My content </div>
I want the component to write "My content" where I specify.
In MyComponent.html:
<wicket:panel>
//Some other code
TRANSCLUDE HERE: "My content" should be here.
</wicket:panel>
Thanks in advance
This is what org.apache.wicket.markup.html.border.Border component does.
The markup of a Border looks like:
<wicket:border>
// some HTML with or without wicket:id here
<wicket:body/>
// some more HTML with or without wicket:id here
<wicket:border>
At the usage site you have:
<div wicket:id="myborder">
// anything here will replace <wicket:body/> in the snippet above
</div>

How to specify className attribute for div which contains 'hello world':
<div dangerouslySetInnerHTML={{__html: '<div>hello world</div>'}} />
One way is to set is to outer div like so:
<div dangerouslySetInnerHTML={{__html: '<div>hello world</div>'}} className='class-name'/>
and then in css style the child:
.class-name div {
(css stuff here)
}
But I want to set className directly to the div with 'hello world'
EDIT: Adding class name to injected html does not solve the problem, for example:
let content = '<div class="class-name">hello world</div>'
<div dangerouslySetInnerHTML={{__html: content}}
does not work, because in case same content is used many times then CSS collisions occur (I am using style-loader with CSS modules on)
I came across this question after 2 years and I wanted to achieve the exact same results. I didn't find any accurate answers here but I came up with a solution thanks to #jash8506 due to the brilliant answer to this question.
We have to utilize two react hooks
useRef
useLayoutEffect
According to the documentation basically, useRef can be used to access the DOM elements in React and useLayoutEffect can be used to read layout from the DOM and synchronously re-render.
We can access the firstChildElement in the container div and add classes to it's classList
Here is how the completed code looks like
const containerRef = useRef();
useLayoutEffect(()=>{
if (containerRef.current){
containerRef.current.firstElementChild.classList.add('class-name');
}
});
return (
<div ref={elRef} dangerouslySetInnerHTML={{__html: '<div>hello world</div>'}} />
)
<div className="post-excerpt" dangerouslySetInnerHTML={{ __html: post.excerpt}}/>
In this implementation below, I got an md-sidenav component with a local template variable #sidenavsearchArea.
<md-sidenav #sidenavSearchArea align="" mode="push" opened="false">
sidenav content here..
</md-sidenav>
I'd like to style the area where it says "sidenav content here.."
How do you refer to this section from the styles.css?
md-sidenav #sidenavSearchArea {
/* does not seem to be the right way */
}
My only solution was to break the DRY principle and introduce a new ID ( id="sidenavSearchArea" into the component ) and do it the old school way, like this:
<md-sidenav id="sidenavSearchArea" #sidenavSearchArea align="" mode="push" opened="false">
sidenav content here..
</md-sidenav>
style.css
#sidenavSearchArea {
/* this approach works but not DRY */
}
Is there a better way to achieve the same thing without the addition of id=""?
Template variables are only for Angulars internal use. They are never added to the DOM and therefore not available for CSS styling.
You need to additionally add something that is available to CSS selectors, like a class:
<md-sidenav class="sidenavSearchArea" #sidenavSearchArea align="" mode="push" opened="false">
sidenav content here..
</md-sidenav>
md-sidenav.sidenavSearchArea {
/* does not seem to be the right way */
}
.mat-drawer{
background-color:red;
}

My web app shows body background for a second then it loads the dynamic background when i route from one page to another. I am trying to remove that white flash by adding a splash screen using AngularJS. I looked at some tutorials but were not able to find exact solution.
how do i avoid showing the white body background before my div background loads?
any suggestions?
HTML
<body class="hold-transition skin-blue sidebar-mini sidebar-collapse">
<div class="wrapper" ng-style="{'background': backgroundImg}" >
<div class="content-wrapper">
<section class="content">
<div ng-view></div>
</section>
</div>
</body>
my route
$routeProvider.when('/about',{
templateUrl:'partials/about.php',
controller: 'pageController'
});
My controller
app.controller("pageController",function($scope, $rootScope){
$scope.title = "About Us";
$rootScope.backgroundImg="url('http://abounde.com/uploads/images/abt-min.jpg')"; //abt bg
$scope.$on('$viewContentLoaded', function() {
console.log("about page loaded");
});
});
From what I understand, the pb is that when you route to another page then you launch a new request to download your background with your url(...). Because this request can take time then you have your white screen.
So a solution could be to "preload" all background images when you open your app. So before displaying anything on your app you can display a "loading..." div. In background download all your backgrounds.
Once this is done, when changing route then simply change the css class of your wrapper div to the css class containing the correct background image.
On this particular page, you could have a div that wraps the entire document.
Give this div a class with css ie .document-wrapper-invisible
in your css give .display-none class a display property of none
.dislay-none {
display: none;
}
When your view content loaded function runs, remove this class. You can simply set a variable to be true and use ng-class to conditionally remove the class. ie
<div ng-class="{display-none: !documentLoaded}">
// your page content
</div>
in your controller
$rootScope.$on('$viewContentLoaded', function() {
console.log("about page loaded");
$scope.documentLoaded = true;
});
Something along these lines should work (I've only ever used rootScope for the viewContentLoaded event, if $scope works on it's own then great)
I am currently using the Flatiron Template in Squarespace 6. Each image in the gallery currently displays the image, a title, and -view- under it. I am looking to change -view- to a different name (a city to be specific) that is unique to each gallery item.
The source code for one of the grid items is this:
<script>
Y.use('squarespace-ui-base', function(Y) {
Y.one(".project-item .meta h1").plug(Y.Squarespace.TextShrink);
});
</script>
<!-- Main Grid -->
<div id="grid" data-collection-id="53ebab59e4b0c8271c405596">
<div class="item">
<a href="/diesel-pop-up-brooklyn-nyc/" data-dynamic-load data-dynamic-receiver="#detail_53ee8134e4b020d5c7faa7b3" >
<div class="wrapper">
<div class="project-title">
<h2>DIESEL POP-UP</h2>
<h3>— view —</h3>
</div>
</div>
<img class="thumbnail loading" data-src="http://static.squarespace.com/static/52937e51e4b006a2894ed2fb/t/540e3941e4b0438c2051340c/1410218366032/2.jpg" data-image="http://static.squarespace.com/static/52937e51e4b006a2894ed2fb/t/540e3941e4b0438c2051340c/1410218366032/2.jpg" data-image-dimensions="480x642" data-image-focal-point="0.5,0.5" alt="2.jpg" data-load="false" />
<noscript><img src="http://static.squarespace.com/static/52937e51e4b006a2894ed2fb/t/540e3941e4b0438c2051340c/1410218366032/2.jpg?format=original"></noscript>
</a>
</div>
I have tried using this in the custom CSS section (just to attempt at targeting one item) but it has only effected the page that the image links to, not the image itself.
.project-item[data-dynamic-href='/diesel-pop-up-brooklyn-nyc/'] {
background-color: red;
}
Is there a code that can target each individual element?
Go to:
Page > Settings > Advanced > Header injection (Index page)
Then paste the following:
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function () {
$(".item:nth-child(1) h3").text("1st item");
$(".item:nth-child(2) h3").text("2nd item");
$(".item:nth-child(3) h3").text("3rd item");
$(".item:nth-child(4) h3").text("4th item");
});
</script>
Cool. Now you can change the text in the quotations (1st, 2nd, 3rd, 4th item) to whatever text you want to replace 'view'. If you have more than 4 galleries in the index, you can copy a line and paste it below, but just make sure to increase the nth-child item from (4) to (5).
Hope that helps!
Thanks for adding the additional data. Unfortunately you cannot do this. Changes in SquareSpace are global changes. You can make a cosmetic change to all galleries but you cannot target a specific gallery by ID. Squarespace object IDs are dynamic and session based. If you target a specific object ID in your CSS, once you refresh the page the ID will change and the CSS will no longer be valid.
However if there is a scenario where you have individual galleries on separate pages then you can work around the global change by inserting the CSS at the "page" level under settings and not a the site level that calls the object category (not the object ID).
Also changing the content of a label is not a css change. That is an HTML change. In Squarespace you cannot modify/hack the actual HTML in the templated versions.
Using Sitecore (7) & MVC, I'd like to know how to add a css class attribute for an image to the field renderer in sitecore.
Without Sitecore it looks like this:
<div class="background-container">
<img src="/images/background-1.jpg" class="background">
</div>
With Sitecore:
<div class="background-container">
#Html.Sitecore().Field(Constants.Fields.HomeBackgroundImage)
</div>
There doesn't seem to be a way to add the class background to the image itself in Sitecore. Is there another way to do this?
Thanks.
This was what I was looking for:
#Html.Sitecore().Field("MyFieldName", myItem, new { Parameters = new SafeDictionary<string> { { "enclosing-tag", "h2" } } })
