I have a html element that looks like this:
<h1 [style.font-size.em]="mysize" id="title-text" #titleText>{{ screenInfo.title }}</h1>
Where mysize is a variable that controls the font-size of the h1 tag. The h1 element's width is determined by the fontsize of the content.
I'm getting a reference to the h1 tag with
#ViewChild('titleText') titleTextElement;
If i run the following code i get the following results
console.log(this.titleTextElement.nativeElement.offsetWidth);
// returns 632px, which is the correct width.
this.mysize *= 0.9;
console.log(this.titleTextElement.nativeElement.offsetWidth);
// returns 632px, but the new width is 572px.
Can anybody explain why this does not work? I would also appreciate if someone could show how I could get the updated offSetwidth value.
The view is only updated when change detection is run.
You can invoke change detection manually like:
constructor(private cdRef:ChangeDetectorRef) {}
...
console.log(this.titleTextElement.nativeElement.offsetWidth);
// returns 632px, which is the correct width.
this.mysize *= 0.9;
this.cdRef.detectChanges();
console.log(this.titleTextElement.nativeElement.offsetWidth);
// returns 632px, but the new width is 572px.
ant it should work as expected.

I'm using Stylus' interpolation like so:
for num in (1..12)
.foot:nth-of-type({num})
left 8.33% * num
&:after
content \'{num}\' // ??? This isn't working
The part that's getting me is the content property. It's supposed to set to 1-12 respectively matching the nth-of-type. But no matter what I try it seems to be blank. Is this possible? If so, what am I doing wrong?
It appears that putting num in () fixes the issue:
content \'(num)\'
when the text attribute is set to
text-overflow: ellipsis;
the overflowed text will be displayed as "XX..." (see screenshot for more )
how can I find the overflowed text/element in webdriver?
thanks in advance

Probably the easiest/best way to do this is to use the JS innerText property, e.g.
driver.findElement(lcoator).getAttribute("innerText");
If I remember correctly, some browsers use textContent instead.
driver.findElement(lcoator).getAttribute("textContent");
This should get you the full text inside that element.
You could also pull innerHTML and parse it (if needed) or remove the text-overflow style from the element but these are harder/more complicated.
In case you have jQuery available in your project, you can write your own selector:
$.expr[':'].truncated = function (e) {
// you *might* want to check if css property "text-overflow"
// is set to "ellipsis" as well, to filter other truncations:
return e.offsetWidth < e.scrollWidth;
};
and go from there:
items = $('.your-selector:truncated');

I have a number of Div's on a layout, each of them draggable, so there's the possibility of the user dragging them into positions where they will overlap.
I want to set the most recently made visible div to have a z-index value that's +1 from the last, and for this I'm using a $scope.nextIndex variable that's incremented each time one of the div's is made visible.
Each div has its own variable to track its own z-index value: $scope.one_zIndex, $scope.two_zIndex, $scope.three_zIndex, and each correctly gets assigned an incrementally larger value as each div is shown, hidden and shown again.
Each div has its own class: one_z, two_z, three_z
What I can't make work is assigning the variable to the z-index style on the divs themselves via the controller.
var myVar = document.getElementsByClassName("one_z");
If I log this to the console, I get what I expect - an array with one element [0]
[]
0 : div#one_z
length : 1
one_z : div#one_z
__proto__ : HTMLCollection
I would assume that I could set the z-index simply like this:
myVar[0].style.zIndex = $scope.one_zIndex;
However this throws an error:
Uncaught TypeError: Cannot set property 'zIndex' of undefined
What am I missing? Or is there a better way to accomplish this?
Here is a working plunker https://plnkr.co/edit/aaDipIWdqpajghc2F2Da?p=preview
You can set zindex via ng-style:
<div ng-style="{'z-index': $lastIndex;}">...</div>
This example completely useless in your case, but there is an example of ng-style usage. In your case I'd set index as property of you div element data source.
What wound up working was this:
First, I switched to IDs instead of classes, which likely didn't impact the solution but as each div was only ever going to exist once, IDs was the more correct way of identifying them.
Then, in the function that displays the div, I used this:
_.defer(function(){
jQuery('#one_z').css('z-index', $scope.one_zIndex);
});
There appeared to be an issue where I was showing the div and trying to set its z-index before the DOM had updated to include the div, so _.defer (I'm using Underscore.js) prevented the accessing of the z-index until everything had updated once, and it works.
As I mentioned in another comment - using ng-style wasn't working for me, and I had tried the _.defer with that approach as well initially without success.
For the record - I've used jQuery() instead of $() so it's clear in the code that this is a jQuery and not an Angular solution, and while I'd ideally have liked a purely Angular solution to this problem, this is clean enough for me, and doesn't do any DOM manipulation outside of Angular's purview that impacts the rest of the application in any way, it's purely display candy.
What is the preferred way of using a number filter in ng-style? I have an image that I want to only be set to a whole number pixel value of height.
<img src="ok-button.png" ng-style="{'height': textHeight * 1.888 | number:0}">
The above code does not work but reflects what I'm trying to do.
Height property should have mentioned in pixel so you need to add px to indicate it is pixel.
You were using number filter which is used to change text to , separated currency representation, which would applicable to solve your case.
For rounding pixels you should have define function inside controller which will do Math.roud of that value & return it to the view.
HTML
ng-style="{'height': round(textHeight) + 'px'}"
Code
$scope.round = function(textHeight){
var result = textHeight * 1.88;
return Math.roud(result);
}
I'm making a responsive site and need to include a Facebook Like-Box for the client's Facebook fanpage. The developer page for the like-box has a widget for customization, but it doesn't allow you to set a width in percentages.
I've searched around and the closest I've got was this page from 2010, which refers to a fb:fan widget that allows you to link custom CSS. I tried to get this tutorial to work but it fails with this error:
<fb:fan> requires one of the "id" or "name" attributes.
So, to recap, I need a Facebook Like Box that I can either set up to be fluid, or which allows me to pass custom CSS to the iFrame it generates. Anyone able to point me in the right direction?
I found this Gist today and it works perfectly: https://gist.github.com/2571173
/* Make the Facebook Like box responsive (fluid width)
https://developers.facebook.com/docs/reference/plugins/like-box/ */
/* This element holds injected scripts inside iframes that in
some cases may stretch layouts. So, we're just hiding it. */
#fb-root {
display: none;
}
/* To fill the container and nothing else */
.fb_iframe_widget, .fb_iframe_widget span, .fb_iframe_widget span iframe[style] {
width: 100% !important;
}
You thought it couldn't be done? AHA! Have at you, Facebook and your wicked fixed-width ways: I wrote a JQuery script to undo all your evil!
$(document).ready(function(){
var fbWidth;
function attachFluidLikeBox(){
// the FBML markup: WIDTH is a placeholder where we'll insert our calculated width
var fbml = '<fb:like-box href="http://www.facebook.com/YOURFANPAGEORWHATEVS" width="WIDTH" show_faces="false" stream="true"></fb:like-box>';//$('#likeBoxTemplate').text().toString();
// the containing element in which the Likebox resides
var container = $('#likebox');
// we should only redraw if the width of the container has changed
if(fbWidth != container.width()){
container.empty(); // we remove any previously generated markup
fbWidth = container.width(); // store the width for later comparison
fbml = fbml.split('WIDTH').join(fbWidth.toString()); // insert correct width in pixels
container.html(fbml); // insert the FBML inside the container
try{
FB.XFBML.parse(); // parses all FBML in the DOM.
}catch(err){
// should Facebook's API crap out - wouldn't be the first time
}
}
}
var resizeTimeout;
// Resize event handler
function onResize(){
if(resizeTimeout){
clearTimeout(resizeTimeout);
}
resizeTimeout = setTimeout(attachFluidLikeBox, 200); // performance: we don't want to redraw/recalculate as the user is dragging the window
}
// Resize listener
$(window).resize(onResize);
// first time we trigger the event manually
onResize();
});
What is does is it adds a listener to the window's resize event. When it resizes, we check the width of the Likebox' containing element, generates new XFBML code with the correct width, replaces the containing element's children with said XFBML and then trigger the Facebook API to parse the XFBML again. I added some timeouts and checks to make sure it doesn't do anything stupid and only runs when it needs to.
Much has changed since the OP.
By simply choosing iFrame and setting your width to 100%, your FB Like Box should be responsive.
Basically FB adds this to the iFrame:
style="border:none; overflow:hidden; width:100%; height:300px;".
Been struggling with the exact same problem. A quick & simple solution is to use the iframe based Facebook Like box.
<iframe class="fb-like-box" src="//www.facebook.com/plugins/likebox.php?href=http%3A%2F%2Fwww.facebook.com%2Fplatform&width=292&height=500&colorscheme=light&show_faces=true&border_color&stream=true&header=true" scrolling="no" frameborder="0" allowTransparency="true"></iframe>
Note the assigned 'fb-like-box' class and all the removed inline styles. The class for the iframe could look something like this:
.fb-like-box {
width: 100% !important;
height:500px;
border:none;
overflow:hidden;
}
Looks like it doesn't matter what the height and width are that are defined in the iframe's src tag. Just place the iframe into some fluid element like a cell in a CSS grid layout.
(includes ideas from: http://updateox.com/web-design/make-facebook-comment-and-like-box-fluid-width/)
I used the HTML5 version of Facebook Like Box and here is what worked for me:
.fb-like-box,
.fb_iframe_widget span,
.fb_iframe_widget iframe {
width:100% !important;
}
You cannot set the like-box to anything other than a pixel width. My suggestion is to place it in a DIV or SPAN that is fluid with overflow set to hidden. Sure, it's going to crop off part of the like-box, but by having the requirement of fluid, this is your best bet.
Here's a small work around that appends the HTML5 Facebook LikeBox Plugin into the DOM with a response height or width.
$(document).ready(function(){
var height = $(window).height();
var width = $(window).width();
var widget_height = parseInt((height)*0.9);
var widget_width = parseInt((height)*0.3);
var page_url = "http://www.facebook.com/Facebook";
$(".fb-plugin").append("<div class='fb-like-box'
data-href='"+page_url+"'
data-width='"+widget_width+"'
data-height='"+widget_height+"'
data-colorscheme='dark'
data-show-faces='true'
data-border-color='#222'
data-stream='true'
data-header='true'>
</div></div>");
});
The comment above from Ed and Matthias about using 100% for the iframe worked great for me. Here is my iframe code
ORIGINAL WITHOUT FIX:
<iframe src="//www.facebook.com/plugins/likebox.php?
href=https%3A%2F%2Fwww.facebook.com%2FXXXXXXXXXX&
width&height=290&colorscheme=dark&
show_faces=true&header=true&stream=false&
show_border=true&appId=XXXXXXXXXX"
scrolling="no" frameborder="0"
style="border:none; overflow:hidden; height:290px;"
allowTransparency="true"></iframe>
UPDATED WITH 100% FIX:
<iframe src="//www.facebook.com/plugins/likebox.php?
href=https%3A%2F%2Fwww.facebook.com%2FXXXXXXXXXX&
width&height=290&colorscheme=dark&
show_faces=true&header=true&stream=false&
show_border=true&appId=XXXXXXXXXX"
scrolling="no" frameborder="0"
style="border:none; overflow:hidden; height:290px;width:100%"
allowTransparency="true"></iframe>
The only change is adding "width:100%" to the style attribute of the iframe
note that the code above has "XXXXXXXXXX" in place of the unique references
