Here is my angular code:
<div ng-repeat="s in doc.Summaries">
<a href="#" ng-click="doc.summaryIdShown = s.index">
{{s.SummaryState}}: {{s.StopLightColor}}, {{s.LevelOfEvidence}} - {{s.UserName}} - {{s.UpdateTimeStamp | date}}
</a>
<br />
<br />
</div>
In the code I am displaying a link for every version (s in doc.Summaries) of a document. Then, when a user clicks on the link I update my model variable "summaryIdShown" and the version being presented on the side is updated. The issue is: I would like to update these links so that the link corresponding to the version being shown so that it looks different. How would I do that?
I thought about writing a custom directive but I am having trouble with the implementation.
Thanks in advance.
Add ng-class directive, pass in an object which has a class name you want to add and a boolean condition which it should check:
<div ng-repeat="s in doc.Summaries">
<a href="#" ng-click="doc.summaryIdShown = s.index" ng-class="{'green': doc.summaryIdShown === s.index}">
{{s.SummaryState}}: {{s.StopLightColor}}, {{s.LevelOfEvidence}} - {{s.UserName}} - {{s.UpdateTimeStamp | date}}
</a>
<br />
<br />
</div>
CSS:
.green {
color: green;
}

I'm currently trying to figure out how to use templates in angular. At present, I'm playing with ui.router (angular-ui-router) but I can't find good documentation on how the templating language is used to embed a sub-template view, especially as relates to a repeating element for different model instances.
BACKGROUND:
I am basically converting a static-local-filesystem image uploader/manager to work with amazon S3. The background essentials are already worked out, now I'm trying to improve the UI itself by converting it from 10 year old javascript to angular.js. I have it 'working' for an all-in-one html page but would prefer to modularize it to make it more dynamic.
CONTEXT:
I get a list of objects under a given prefix back from a listObjectsV2() call to the AWS sdk via the s3 client. I parse the results to break it into a pseudo-directory tree then display one directory at a time starting at the [virtual] root dir just after the prefix. (FYI the prefix is a userid)
I built a UserDir object that uses a PseudoDir sub object to define a virtual directory with array properties for 'subdirs' (more PseudoDir objects representing virtual sub-directories) and 'images' (S3 objects that are image files of one type or another).
What I want to display for any given 'current' directory (e.g. "" or the user root) is first a list of folder icons for each the curDir.subdirs, then a thumbnail icon for each of the curDir.images.
QUESTION:
I already have this working from a single html file and even managed to figured out how to use ui.router to create a for the main page. Now I want to modularize it so that a different controller will handle folder icon/info behavior, and another for image icons/behaviors.
i.e. I have already started building a 'FolderController' and a 'ImageController' and would like the ngRepeat for 'image in curDir.images' for example, to invoke a state with it's own template but I can't seem to find an example on how to do that.
Here is the current all-in-one template code. But I would like to move each sub-block into a state for FolderController with a templates/folder.html template and one for ImageController with a templates/image.html but can't seem to find an example of how to write the syntax:
<!-- folders -->
<div ng-repeat="(folder, pDir) in subdirs" ng-controller="FolderController" ng-init="folderName=folder;awsObject=pDir">
<div id="{{folderName}}" class="Item">
<div class="Icon ui-draggable ui-draggable-handle">
<img id="{{folderName}}Icon" src="../../images/folder.png">
</div>
<div id="{{folderName}}Desc" class="Description">
<span id="{{folderName}}Name" class="filename" title="{{folderName}}/">{{folderName}}/</span>
</div>
</div>
</div>
<!-- images -->
<div ng-repeat="(filename, uImage) in images" ng-controller="ImageController" ng-init="uImage=uImage">
<div id="image{{uImage.hash}}" class="Item">
<div class="Icon ui-draggable ui-draggable-handle">
<img id="icon{{uImage.hash}}" ng-src="{{ uImage.thumbSrc }}"></div>
<div id="desc{{uImage.hash}}" class="Description">
<span id="name{{uImage.hash}}" class="filename" title="{{filename}}">{{filename}}</span>
<img id="thumb{{uImage.hash}}" src="../../images/tick_image-services.png" class="Check Right" ng-show="uImage.usedInLayout" title="Used in layout"><br />
<span id="date{{uImage.hash}}" ng-show="(uImage.mtime > 0)">Date uploaded: {{ uImage.mtime | date: 'EEE MMM dd yyyy' }}</span><br />
<span id="size{{uImage.hash}}" ng-show="(uImage.size > 0)">Size: {{ uImage.size | humanizeBytes }}</span><br />
<span id="dims{{uImage.hash}}" ng-show="((uImage.width > 0) && (uImage.height > 0))">Dimensions: {{ uImage.width }} x {{ uImage.height }} pixels</span><br />
<span id="aspect{{uImage.hash}}" ng-show="(uImage.aspectRatio)">Aspect Ratio: <span class="AspectRatio">{{ uImage.aspectRatio }}</span></span><br />
</div>
</div>
</div>
You can create two components, one for folders and one for images, see here for official docs.
A rough draft would look like:
angular.module('myApp').component('images', {
templateUrl: 'imageList.html',
bindings: {
images: '='
}
});
imageList.html:
<div ng-repeat="(filename, uImage) in images" ng-controller="ImageController" ng-init="uImage=uImage">
<div id="image{{uImage.hash}}" class="Item">
<div class="Icon ui-draggable ui-draggable-handle">
<img id="icon{{uImage.hash}}" ng-src="{{ uImage.thumbSrc }}"></div>
<div id="desc{{uImage.hash}}" class="Description">
<span id="name{{uImage.hash}}" class="filename" title="{{filename}}">{{filename}}</span>
<img id="thumb{{uImage.hash}}" src="../../images/tick_image-services.png" class="Check Right" ng-show="uImage.usedInLayout" title="Used in layout"><br />
<span id="date{{uImage.hash}}" ng-show="(uImage.mtime > 0)">Date uploaded: {{ uImage.mtime | date: 'EEE MMM dd yyyy' }}</span><br />
<span id="size{{uImage.hash}}" ng-show="(uImage.size > 0)">Size: {{ uImage.size | humanizeBytes }}</span><br />
<span id="dims{{uImage.hash}}" ng-show="((uImage.width > 0) && (uImage.height > 0))">Dimensions: {{ uImage.width }} x {{ uImage.height }} pixels</span><br />
<span id="aspect{{uImage.hash}}" ng-show="(uImage.aspectRatio)">Aspect Ratio: <span class="AspectRatio">{{ uImage.aspectRatio }}</span></span><br />
</div>
</div>
and your original html would look like:
<!-- folders -->
<div ng-repeat="(folder, pDir) in subdirs" ng-controller="FolderController" ng-init="folderName=folder;awsObject=pDir">
<div id="{{folderName}}" class="Item">
<div class="Icon ui-draggable ui-draggable-handle">
<img id="{{folderName}}Icon" src="../../images/folder.png">
</div>
<div id="{{folderName}}Desc" class="Description">
<span id="{{folderName}}Name" class="filename" title="{{folderName}}/">{{folderName}}/</span>
</div>
</div>
</div>
<image-list [images]="images" ></image-list>
EDIT
Here is an example plunker which shows a simple implementation of a component, with data binding and ng-repeat in it, no need for ui-router for what you asked for. Please note that the html I wrote above is a botched copy paste of what you wrote - so the double ng-repeat was a mistake, updated the html.
I'm trying to make some textboxes appear everytime a user clicks a button.
i'm doing this with ngFor.
For some reason, the ngFor won't iterate.
I've tried using slice to change the array reference, but still, the text boxes won't appear.
Any idea what i'm doing wrong??
Below are the HTML and component codes.
Thanks!!!
export class semesterComponent {
subjectsNames = [];
addSubject(subjectName: string) {
if (subjectName) {
this.subjectsNames.push(subjectName);
this.subjectsNames.slice();
console.log(subjectName);
console.log(this.subjectsNames);
}
};
<div class="semester-div">
<ul>
<li ngFor="let subject of subjectsNames">
<span>
<input #subjectName type="text" />
<input id = "subjectGrade" type = "number"/>
<input id = "subjectWeight" type = "number"/>
</span>
</li>
</ul>
<br>
<button (click)="addSubject(subjectName.value)">add</button>
<br>
</div>
You are missing the * in *ngFor
<li *ngFor="let subject of subjectsNames">
The way you have your controls written subjectName does not exist because the array is empty and therefore the *ngFor does not render it. Clicking the Add button results in a exception that the value doesn't exist on undefined where undefined is really subjectName.
Moving it outside of the *ngFor will make things work:
<input #subjectName type="text" />
<ul>
<li *ngFor="let subject of subjectsNames">
<span>
{{subject}}
<input id="subjectGrade" type="number"/>
<input id="subjectWeight" type="number"/>
</span>
</li>
</ul>
I suspect you also want to further bind the data as you iterate over the subject names but that's outside the scope of the question.
Here's a plunker: http://plnkr.co/edit/HVS0QkcLw6oaR4dVzt8p?p=preview
First, you are missing * in *ngFor.
Second put out
<input #subjectName type="text" />
from ngFor, should work.
In my website, on UI I show information from DB, use "spring". I want to make, if items quantity equals 0, then I hide this "div". If items quantity more than 0, then I show "div"
In html I recive from spring:
<div th:each="viewAvailableWhisky : ${viewAvailableWhisky}">
<div class="tilt pic" id="ShowHide">
<a th:href="#{~/buySelectedWhisky(nameBuyWhiskey=${viewAvailableWhisky.id})}" >
<img th:attr="src=${viewAvailableWhisky.photo}" id="photoId" width="150" height="250"/>
<div>
<b> <span th:text="${viewAvailableWhisky.nameWhisky}">Name</span></b>
</div>
<div>
<b> Quantity: <span th:text="${viewAvailableWhisky.quantityWhisky}"
>quantityWhisky</span>piece</b>
<input type="hidden" id="quantity" th:value="${viewAvailableWhisky.quantityWhisky}"/>
</div>
<div>
<b> $ <span th:text="${viewAvailableWhisky.price}">Price</span></b>
</div>
</a>
</div>
</div>
I think, it's better to make the with use a JS. But I don't understand how, I try use this code. This code can't catch
quantity of goods of each item from a DB
$(document).ready ( function(){
var quantityItems = $("#quantity").val();
console.log(quantityItems);
if(quantityItems>0){
$("#ShowHide").show();
}
else {
$("#ShowHide").hide();
}
});
The th:if="${condition}" attribute is used to display a section of the view if the condition is met.
<span th:if="${student.gender} == 'M'" th:text="Male" />
Furthemore, thymeleaf offers option to display certain section if given condition is NOT met using th:unless
<span th:unless="${student.gender} == 'M'" th:text="Female" />
(For further info see This tutorial or this intro to Thymeleaf conditionals)
To display certain content only if user has specific role, use spring security's integration with thymeleaf.
<div sec:authorize="hasRole('ROLE_ADMIN')">
This content is only shown to administrators.
</div>
More info about Spring Security integration here.
I have a listing of articles here, and I can't figure out how to execute the ng-click function calls on every new article inside the ng-repeat. Right now it works for existing articles, but when new articles are added dynamically (via AJAX), I need those to have the same functionality too.
For example: the ng-click function calls on the "+" sign to reveal social buttons seem to not work once new articles are inserted via AJAX (ie: delete articles, and let list be populated again with new elements)
Does AngularJS provide any tools to do that?
<div>
<div>
<input type="text" ng-model="search">
<span>{{filtered.length}} article(s)</span>
</div>
<div article-listing ng-repeat="article in filtered = (wikiArticles | filter:search)">
<!--Individual article begin-->
<span>
{{article.title}}
</span>
<div>
<a ng-click="articles.removeArticle($index)" title="Delete">
<span>✖</span>
</a>
<a ng-click="articles.toggleShare(article)">
<span class="plus-sign" title="Share">✖</span>
<div social-share ng-show="article.socialShare">
<div ng-click="socialShare = !socialShare" class="addthis_toolbox addthis_default_style addthis_32x32_style"
addthis:title="{{article.title}}" addthis:description="{{article.extract}}" addthis:url="{{article.url}}">
<a class="addthis_button_facebook"></a>
<a class="addthis_button_twitter"></a>
<a class="addthis_button_google_plusone_share"></a>
<a class="addthis_button_reddit"></a>
<a class="addthis_button_hackernews"></a>
</div>
</div>
</a>
</div>
<div>{{article.extract}}</div>
<!--Individual article end-->
</div>
</div>
Code for ng-click calls that don't seem to work for new article insertions
$scope.articles = (function() {
return {
shuffleArticles : function() {
$scope.wikiArticles.reverse();
},
removeArticle : function(index) {
$scope.wikiArticles.splice(index, 1);
$scope.fireAPICalls();
},
toggleShare : function(currArticle) {
var previousState = currArticle.socialShare;
angular.forEach($scope.wikiArticles, function(article) {
article.socialShare = false;
});
currArticle.socialShare = previousState ? false : true;
}
}
})();
Your ng-click calls are actually working- you can watch the ng-show toggle in the debugger.
The problem is that there is nothing to display on the new items you add.
The articles you initially add all have their icons populated with the .addthis classes, for instance here's your Facebook icon element:
<a class="addthis_button_facebook at300b" title="Facebook" href="#">
<span class=" at300bs at15nc at15t_facebook">
<span class="at_a11y">Share on facebook</span>
</span>
</a>
at300bs includes the following css which displays the image:
background: url(widget058_32x32.gif) no-repeat left!important;
However as you add new items, you aren't including the needed .addthis classes to them. Their elements look like this:
<a class="addthis_button_facebook"></a>
So ng-show has nothing to display (it shows a 0x0 div).
Add the .addthis classes to your new elements as you add them and you'll be all set.
I am using the teleriks treeview control (asp.net mvc extensions), where I may have up to three children nodes, like so (drumroll...... awesome diagram below):
it has its own formatting, looking a bit like this:
<%=
Html.Telerik().TreeView()
.Name("TreeView")
.BindTo(Model, mappings =>
{
mappings.For<Node1>(binding => binding
.ItemDataBound((item, Node1) =>
{
item.Text = Node1.Property1;
item.Value = Node1.ID.ToString();
})
.Children(Node1 => Node1.AssocProperty));
mappings.For<Node2>(binding => binding
.ItemDataBound((item, Node2) =>
{
item.Text = Node2.Property1;
item.Value = Node2.ID.ToString();
})
.Children(Node2 => Node2.AssocProperty));
mappings.For<Node3>(binding => binding
.ItemDataBound((item, Node3) =>
{
item.Text = Node3.Property1;
item.Value = Node3.ID.ToString();
}));
})
%>
which causes it to render like this. I find it unsual that when I set the value it is rendered in a hidden input ? But anyway:...
<li class="t-item">
<div class="t-mid">
<span class="t-icon t-plus"></span>
<span class="t-in">Node 1</span>
<input class="t-input" name="itemValue" type="hidden" value="6" /></div>
<ul class="t-group" style="display:none">
<li class="t-item t-last">
<div class="t-top t-bot">
<span class="t-icon t-plus"></span>
<span class="t-in">Node 1.1</span>
<input class="t-input" name="itemValue" type="hidden" value="207" />
</div>
<ul class="t-group" style="display:none">
<li class="t-item">
<div class="t-top">
<span class="t-in">Node 1.1.1</span>
<input class="t-input" name="itemValue" type="hidden" value="1452" />
</div>
</li>
<li class="t-item t-last">
<div class="t-bot">
<span class="t-in">Node 1.1.2</span>
<input class="t-input" name="itemValue" type="hidden" value="1453" />
</div>
</li>
</ul>
</li>
</ul>
What I am doing is updating a div after the user clicks on a certain node. But when the user clicks on a node, I want to send the ID not the Node text property. Which means I have to get it out of the value in these type lines <input class="t-input" name="itemValue" type="hidden" value="1453" />, but it can be nested differently each time, so the existing code I ahve doesn't ALWAYS work:
<script type="text/javascript">
function TreeView_onSelect(e) {
//`this` is the DOM element of the treeview
var treeview = $(this).data('tTreeView');
var nodeElement = e.item;
var id = e.item.children[0].children[2].value;
...
</script>
So based on that, what is a better way to get the appropriate id each time with javascript/jquery?
edit:
Sorry to clarify a few things
1) Yes, I am handling clicks to the lis of the tree & want to find the value of the nested hidden input field. As you can see, from the telerik code, setting item.Value = Node2.ID.ToString(); caused it to render in a hidden input field.
I am responding to clicks anywhere in the tree, therefore I cannot use my existing code, which relied on a set relationship (it would work for first nodes (Node 1) not for anything nested below)
What I want is, whenever there is something like this, representing a node, which is then clicked:
<li class="t-item t-last">
<div class="t-bot">
<span class="t-in">Node 1.1.2</span>
<input class="t-input" name="itemValue" type="hidden" value="1453" />
</div>
</li>
I want the ID value out of the input, in this case 1453.
Hope this now makes a lot more sense.
if possible would love to extend this to also store in a variable how nested the element that is clicked is, i.e. if Node 1.1.2 is clicked return 2, Node 1.1 return 1 and node 1 returns 0
It's a little unclear what you're asking, but based on your snippet of JavaScript, I'm guessing that you're handling clicks to the lis of the tree & want to find the value of the nested hidden field? If so, you want something like this:
function TreeView_onSelect(e) {
var id = $(e.item).find(".t-input:first").val();
}
Edit: In answer to your follow-up question, you should be able to get the tree depth with the following:
var depth = $(e.item).parents(".t-item").length;
In jQuery you can return any form element value using .val();
$(this).val(); // would return value of the 'this' element.
I'm not sure why you are using the same hidden input field name "itemValue", but if you can give a little more clarity about what you are asking I'm sure it's not too difficult.
$('.t-input').live('change',function(){
var ID_in_question=$(this).val();
});
