"allitems" contains all items for a category that is selected in a combobox. That part of the code working properly.
I have images saved in a database as binary data for each item. When an item is displayed then the image of the item shall be rendered. For doing this I have to save item's ID in ASP .Net controller before rendering, because the "RenderImage" needs the Item's ID. This is done by calling "saveItemId" in AngularJS controller.
But the rendering of the images are very unpredictable. "saveItemId" is called repeatedly but not RenderImage.
There is no problem calling methods/saving ID in AngularJS controller or in ASP .Net MVC controller.
<div dir-paginate="r in allitems | filter:q | itemsPerPage: pageSize" current-page="currentPage" ng-init ='saveItemId(r.ID)' class="ag-fresh">
<div style="float:left">
<div class="col-xs-3">
<div style="width:200px;">
<div class="product-image-wrapper">
<div class="single-products">
<div class="productinfo text-center">
<img src="#Url.Action("RenderImage")" height="84" width="84"/>
<br/>
<h>{{r.Price}}</h>
<p>{{r.Name}}</p>
<button class="btn btn-default add-to-cart" ng-click="AddToCart(r.ID)">Add to cart</button>
{{successTextAlert}}
</div>
</div>
</div>
</div>
</div>
</div>
its seems that RenderImage is a js variable in the controller scope. if its so, its need to be call with brackets, like {{RenderImage}}
Try using 'ng-src' instead 'src' attribute, for the img element as described at
https://docs.angularjs.org/api/ng/directive/ngSrc#!
This works properly:
<img ng-src="data:image/jpeg;base64,{{arrayBufferToBase64(r.InternalImage)}}" height="84" width="84"/>
I Added arrayBufferToBase64 to the angular controller.

I am new to AngularJS.
I have created <li> to which I used ng-repeat.
<li> contains images and buttons like like, comment and share which is inside <li> and created by ng-repeat.
I have made function which will replace empty like button to filled like button (By changing background image of button).
But problem is this trigger applies to only first like button and other buttons does not change.
How can I fix this?
Code:
HTML:
<html>
<body>
<ul>
<li ng-repeat="media in images"><div class="imgsub">
<label class="usrlabel">Username</label>
<div class="imagedb">
<input type="hidden" value="{{media.id}}">
<img ng-src="{{ media.imgurl }}" alt="Your photos"/>
</div>
<!-- <br><hr width="50%"> -->
<div class="desc">
<p>{{media.alt}}</p>
<input type="button" class="likebutton" id="likeb" ng-click="like(media.id)" ng-dblclick="dislike(media .id)"/>
<input type="button" class="commentbutton"/>
<input type="button" class="sharebutton"/>
</div>
</div> <br>
</li><br><br><br>
</ul>
</body>
</html>
JS:
$scope.like = function(imgid)
{
document.
getElementById("likeb").
style.backgroundImage = "url(src/assets/like-filled.png)";
alert(imgid);
}
$scope.dislike = function(imgid)
{
document.
getElementById("likeb").
style.backgroundImage = "url(src/assets/like-empty.png)";
}
Thanks for help & suggestions :)
The id for each button should be unique but in your case, it's the same for all buttons ('likeb').
You can set the value of the attribute 'id' for each button dynamically by using '$index' and passing '$index' to the functions as follows:
<input type="button" class="likebutton" id="{{$index}}" ng-click="like($index)" ng-dblclick="dislike($index)"/>
Then in your controller, you can use the functions with the passed value.
For example,
$scope.like = function(index)
{
document.
getElementById(index).
style.backgroundImage = "url(src/assets/like-filled.png)";
}
Another good alternative in your case would be to use the directive ngClass.
use 2 css class for styling liked and disliked state, and then put the class conditionally with ng-class instead of DOM handling. and if you really want to perform a DOM operation (I will not recommend) then you can pass $event and style $event.currentTarget in order to perform some operation on that DOM object.
I am working with angularJS ng-repeat. So, I want to use my ng-repeat value in another div. I am doing the following. But it doesn't loop through and give me the exact value.
Code in ng-repeat
<div uib-slide index="$index" class="uibSlider" ng-repeat='id in code' ng-click="$parent.ContentId = id.ContentId" ng-class="{'selected' : ContentId.Id === ContentId}">
<paragraph tag>{{id.ContentId}}</paragraph tag>
</div>
Code in Another Div
<div>
<label>{{(code| filter: {Id: ContentId}: true)[1].ContentId}}</label>
</div>
So, the problem is I have bunch of data and in the another div if I make the array value from 0 to 1. i'm getting null value. But automatically the value isn't changing based on what I contentID select. It always gives me the same value. I'm not sure where I'm going wrong.
Any Help would be appreciated.
You can use ng-repeat-start | ng-repeat-end
<div uib-slide ng-repeat-start='id in code'>
<paragraph tag>{{id.ContentId}}</paragraph tag>
</div>
<div ng-repeat-end>
<label>{{(id.ContentId}}</label>
</div>
If you are trying to show the same data in a modal, depending where the user clicks:
<div ng-repeat="id in code">
<!-- when the user clicks here, the modal will open. The ID will be the same as the one clicking -->
<a ng-click="openModal(id)">Open modal for id: {{id}}</a>
</div>
Then in your controller you will have a function called openModal which takes a parameter (id) that will open the modal and pass along the data.
I want to create a directive which includes a ng-repeat and I need to bind an event to a contained tag inside the ng-repeat like the "test-class"
<div>
<div ng-repeat="row in ctrl.items">
<div>
<p ng-bind="row.Text"></p>
<a class="test-class"></a>
</div>
</div>
</div>
but my problem seems to be that in the link function the "element" property seems to contain only the ng-repeat and so I can't find the "test-class" within the element because its not there in the link function, that makes sense.
But how can I then access the dom and bind some custom events to the "a" in my example.
The only solution I had is to create two directives one with the ng-repeat and the other with the content inside the ng-repeat. Do I miss something or is this the only possible solution for my problem?
Directive with name "DirectiveContent":
<div>
<p ng-bind="row.Text"></p>
<a class="test-class"></a>
</div>
Then the new complete Directive:
<div>
<div ng-repeat="row in ctrl.items">
<directive-content></directive-content>
</div>
</div>
I'm working on a project where the client has supplied a pile of html where I need to plugin the data from our database and have hit a problem that I'm finding difficult to solve....
So first problem is with routing
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information collapse">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
he has supplied some javascript to handle the click on class-overview
$('.class-overview a').on('click',function(e) {
e.preventDefault();
});
$('.class-overview').on('click',function() {
$('.class-overview.active').removeClass('active').next('.class-information').collapse('hide');
$(this).addClass('active').next('.class-information').collapse('show');//.css('top',offset).collapse('show');
});
and i have a line like this in my state provider
// default route
$urlrouterProvider.otherwise("/")
So the problem is that the ui-router handles the click and sends me back to the home page.
The ideal solution is to leave as much of his markup intact, so can anyone tell me how I stop ui-router handling the click?
or failing that, how I might use ng-click and ng-show to get the same effect, i.e. hiding and showing the class-information div...
If I understand well your question, you want to display the .class-information div when you click on the .class-overview element.
That can be done by using a variable in a ng-show like this:
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#" ng-click="display = !display">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information" ng-show="display">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
The display variable will be falsy when you land on the page, therefore the ng-click will be executed, this variable will be set to true.
I see that you are using a collapse class to hide the content if it is collapsed. Then you could use angular ng-class to put the collapse class when the display variable is false. Your div.class-information would look like this:
<div class="class-information" ng-class="{collapse: !display}">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
I've a situation where I want to display an error message on the page when my modal don't have any records to show. This could be on the initial load or after applying some filter criteria on the page.
I'm using ng-if to check the count of records on the result set after applying the filter, that is why when my page initially loads as there is no data in the filtered result rest it is showing up the error message first and then later it is showing the data.
Any insight would be highly appreciated
prod.skulist is my modal.
<ul class="prd-list">
<li ng-repeat=" p in filtered =(prod.skulist | categoryFilter:prod.selectedFormat :prod.selectedRating) | filter :priceRange" id=" {{p.sku}}">

<span class="new-item" ng-show="{{p.isnew}}"><img src="Content/images/new.png" /></span>
<span class="new-item" ng-show="wrapCtrl.compareStreetDate(p.streetdate)"><img src="/Content/images/coming-soon.png" /></span>

</ul>
<div ng-if="(filtered | filter :priceRange).length ==0" class="error-box">

<div class="wrp error-message">
<span class="f9 pad-top">It looks like I don't have exactly what you are looking for.</span>
<span class="f9 pad-bot">try adjusting your filters to see more</span>
</div>
</div>
I ran into a similar situation and found an ugly, though working solution by using the $timeout service. In your case you would have a scope variable, lets call it loadTimeGiven = false and after the $timeout you set it to true. Then simply do
ng-if="(filtered | filter :priceRange).length ==0 && loadTimeGiven"
Alternatively you could set loadTimeGiven based on a service that your modal has access to.
