I'm experiencing some very peculiar behaviour--I'm new to angular, to spare you the noob questions, I tired my best to find the solution but after many hours, I think it's time to give in and ask.
Code Summary: Alphabet array, is looped(ng-repeat) and each letter is linked to a function called clickLetter(), this function sets a $scope variable that reflects the current chosen alphabet letter.
Problem: the model/variable in charge of displaying the current active letter is not updating ALL the time, it only appears to update sometimes, randomly it seems.
Code (plunker)
My guess is, angular is not updating the model (two-way data-binding?) as fast as it should?
It looks like the <a> tag is triggering a route change. Either add an $event.preventDefault() to it or remove the <a> altogether. (doesn't seem like it's adding any value)...
<div class="ui icon button padding5" ng-class="{'active': letter == activeLetter}" ng-repeat="letter in letters" ng-click="clickLetter(letter, $event)">
{{letter}}
</div>
or
<div class="ui icon button padding5" ng-class="{'active': letter == activeLetter}" ng-repeat="letter in letters" ng-click="clickLetter(letter, $event)">
{{letter}}
</div>
The problem is, when you click on letter and not on button,the link stops the propagation of your mouse click.
Add this class in your css file and apply to <a> tag, which holds the letter:
.ignore-mouse-event {
pointer-events: none;
}
<a> tag should be changed to this:
{{letter}}

I am relatively new to angularJs so I am trying to learn how to do different things. I have been trying to make solutionName act as a p tag if there is no URL input for solutionUrl1, at the moment solutionName is acting as if it is hyperlinked even when its not. Any help would be appreciated.
<a ng-href="{{::data.solutionUrl1}}" class="card__title" style="text-align: center">
<span>{{::data.solutionName}}</span>
</a>
Use ng-if of angularjs to render either one or the other:
Something like this, you most probably have to change the condition to meet your needs. You can also create a new Variable in the JS files like showLink and set this variable to true/false depending on some conditions. And then just use this boolean variable to show/hide the link with the method outlined below:
<div ng-if="data.solutionUrl1">
<!-- code to render the link-->
</div>
<div ng-if="!data.solutionUrl1">
<!-- code to render just the span without the link -->
</div>
I have the following angular-List (reduced the content to make it better readable):
<div ng-repeat="element in bigBlock.Elements track by $index"
class="singleBlockElement"
ng-drop="dragSource=='Block'"
ng-drop-success="To($index, $data, bigBlock)">
<div class="bbRange"> </div>
<i class="fa {{GetImage(element)}}" />
<div ng-drag="element.ElementType!=='placeholder'"
ng-drag-data="element"
ng-drag-start="Start()"
ng-drag-success="From(element,bigBlock, $index, bigBlock.$index)"
ng-drag-stop="Stop(element, bigBlock, $index, bigBlock.$index)"
class="cutOff">
{{element.Title}}
</div>
<div class="edit ng-show="GetLinkText(element, true)">
<span class="isvisible">
<i title="{{element.Present?'Präsentieren':'Nicht präsentieren'}}" class="fa fa-{{element.Present?'eye':'eye-slash'}}"></i>
</span>
{{GetLinkText(element,true)}}
</div>
</div>
This is how it looks like:
This is while dragging:
And this is how it looks like when I simply don't drop like described below:
I can now (successfully) drag & drop the two elements ("Welcome" and "Go Away") inside that block changing the order of these two.
But if I abort the drag/drop. e.g. Dragging "Welcome" and not moving it downwards or moving it to an area where I cannot drop (outside the block) the text "Welcome" disappears.
There are no errors. The drop is just not happing (as expected), but Angular seems to be unable to redisplay the text of that element. ({{element.Title}})
I event tried forcing a refresh using $apply(), but this did not change a thing (not creating an error either).
However, if I do ANYTHING on the page like clicking on an edit-button or anything else that causes an event, the date is correctly shown again.
So it looks like a refresh issue for me.
I am using ngDraggable for this (https://github.com/fatlinesofcode/ngDraggable)
(Update: Analyzing the page source in Developer Console of Chrome the text still seems to be there and even "should" be visible (display:block), so this might be more of a browser-issue (chrome) than an angular-issue)
This seems to be a pure Browser/CSS-Issue and not an Angular-Issue. I solved this by forcing the browser to refresh the parent container:
$('.mm-Right')[0].style.display = 'none';
$('.mm-Right')[0].offsetHeight;
$('.mm-Right')[0].style.display = 'block';
where my structure is
<div class='mm-Right'>
<div class='singleBlockElement>[..]</div>
<div class='singleBlockElement>[..]</div>
<div class='singleBlockElement>[..]</div>
</div>
That did solve the problem but looks like cheating for me. I would prefer that this bug not even appears instead of hiding the symptoms. So I am happy to accept any better answer for that problem.
I'd like to show element only one time within ng-repeat.
My code bellow doesn't work because "Event of today" is shown each time when an event is starting today...
My code :
<div class="line" ng-repeat="event in events">
<!-- h4 only once if condition is passed -->
<h4 ng-if="event.start.getTime() === today.getTime()">Event of today</h4>
<!-- h4 only once if condition is passed -->
<h4 ng-if="event.start.getTime() === tomarrow.getTime()">Event of tomarrow</h4>
<div class="event-body">
<h3>{{event.categoryName}} : {{event.title}}</h3>
</div>
</div>
Just create a filtered version of the events array and display that. You can make a function that refilters it, and call that whenever there's a change that needs it to update (putting it in a $scope.$watch function seems the easiest way to do this). It seems low-tech, but it really gives you the most control over what you end up seeing.
Here is a very stripped-down Plunker of this, just showing some simple filtering: Example.
So i have four progress bars that on click open and close via the close button in the top right....problem is the ngrepeat is messing with something....i've tried adding $parent to the child ngClick but it doesnt work. I've looked at all the other stack examples of this and just can't seem to figure out how to apply it to this specific situation
http://codepen.io/anon/pen/JorZoE
<div class="progress-bar repeat-animation" ng-click="showClose = false" ng-class="!showClose ? 'grow' : ''" progress-morph style="width: {{item.percent}}%" ng-repeat="item in list">
<div class="close" ng-hide="showClose" ng-click="onClickClose($event)" ><img src="close42.svg" alt=""></div>
</div>
I assumed that you wanted to open/close the bars individually.
If that's the case, your code wasn't working because you were binding all the progress bars state to the same $scope variable.
Having that in mind, I tweaked your code a little bit to make it work, and also used a more readable logic (imho).
Please take a look and let me know:

I have this in my template:
<div ng-repeat="item in mainCtrl.items" class="item">
<h4 ng-bind="item.title"><small ng-bind="item.pub_date"><strong></strong></small></h4>
<p ng-bind="item.content"></p>
</div>
the item.content and item.content shows respectively. However, the item.pub_date don't show the value in there. I get empty portion at where the date should be in my rendered template.
Using Batarang, I realized the pub_date value shows in the template, but doesn't render or what.
This is how it appears when I look it up in batarang
pub_date: 2014-12-05T18:27:30.939Z
Do I need to add a date filter to make it work? I'm not exposing the value within the pub_date item properly or? Thanks
That is because your h4 tag wrapping small tag which overrides its content. The ngBind directive basically replaces the existing content.
Either move small out of h4 or use double curly notation for the title as:
<h4>{{item.title}}<small ng-bind="item.pub_date"><strong></strong></small></h4>
