I'm using angular grid -
let's say i have a scope object as follows:
$scope.test = 3
If I want to dynamically set an html id, I would do something like this:
<div id="{{test}}"></div>
Checking the DOM, I see the following:
<div id="3"></div>
For my angular grid, I want to do something like this:
<div ag-grid="{{test}}"></div>
Checking the DOM I literally get:
<div ag-grid="{{test}}"></div>
Is there a way around this?
You can use ngAttr and do this like the following:
ng-attr-ag_grid="{{test}}"
Please check if this helps
Use
<div ag-grid="test"></div>
Check following link and check first example html file forag-grid tag with binding variable
Note: Based on example test should be object not string or other type.
Is {{ }} necessary?
You can try:
ag-grid="test"

I am using an Angular Wrapper for JSON Editor like this:
<div *ngFor="let act of editedActions" class="w-100-p p-24">
{{act.test_step_id}}
<json-editor [options]="editorOptions" [(data)]="act.action_json" [(eventParams)]="act.test_step_id" (jsonChange)="changeStepActions($event)"></json-editor>
<button mat-raised-button class="w-100-p mt-24" color="primary" (click)="editRecordJson(act.test_step_id)">
<span>Update</span>
</button>
</div>
The problem is that eventParams should be different for each editor but it is not varying.
I think problem is this component code (but not sure) (This line is in the component taken from github):
#ViewChild('jsonEditorContainer', { static: true }) jsonEditorContainer: ElementRef;
The component is behaving like a singleton. Any help?
Edit: I edited this repo and added jsonchange event. Details here
You may want to use #ViewChildren with a direct reference to the component instead of a template variable string, to get all the JSON editors references:
#ViewChildren(JsonEditorComponent) jsonEditorContainers: QueryList<ElementRef>;
// ...
jsonEditorContainers.find(...);
It returns a QueryList that allows you to iterate through all ElementRef, and monitor the changes with an Observable changes.
What is eventParams? What is jsonChange? I could be wrong, but data doesn't seem to be two way bindable either, according to the source code.
It seems like you might be looking for something like this:
<div *ngFor="let act of editedActions" class="w-100-p p-24">
<json-editor [options]="editorOptions"
[data]="act.action_json"
(change)="changeStepActions($event, act.test_step_id)">
</json-editor>
</div>
You can then read the test_step_id in your changeStepActions method. If this works, I don't know how you made it compile in the first place.. are you using a CUSTOM_ELEMENTS_SCHEMA?
Its not necessary to use #ViewChildren for that you have to rewrite the entire code of component, make sure while using #ViewChild you pass correct editor reference.
As following
#ViewChild('carEditor' ) carEditor: JsonEditorComponent;
#ViewChild('mobileEditor') mobileEditor: JsonEditorComponent;
Stackblitz example for refernce :

To use multiple jsoneditors in your view you cannot use the same editor options.
You should have something like:
<div *ngFor="let prd of data.products" class="w-100-p p-24" >
<json-editor [options]="makeOptions()" [data]="prd" (change)="showJson($event)"></json-editor>
</div>
makeOptions = () => {
return new JsonEditorOptions();
}
I have a template that contains the following fragment:
<spark class="col-12" value="80"></spark>
I also have a variable accessible to this template as {{ratio}} such that if I change my fragment to:
<spark class="col-12" value="80"></spark>
Ratio: {{ratio}}
the correct ratio will be displayed on a page.
This is what does not work:
<spark class="col-12" value="{{ratio}}"></spark>
which results in "{{ratio}}" string being displayed.
Any ideas ?
You should be using the built-in directives for adding attribute values from the scope, for example ng-src, ng-style, ng-href, so on.
Documentation for the built-in directives
Will ng-attr work for you? ng-attr-value="{{ratio}}"

I am currently trying to add links in my view. I do have links which basically contains html tags as strings.
I tried:
<p data-ng-repeat='i in links' >{$ i.link $}</p>
which basically just deploy in my view : mylink
So I did try:
<p data-ng-repeat='i in links' ><span data-ng-bind-html="i.link"></span></p>
It doesn't work though, any idea how could I achieve this ?
Thanks.
Add the $sce as a dependancy of the module
angular.module('myApp', ['$sce']);
When getting the links
angular.forEach($scope.links, function(value){
value.link = $sce.trustAsHtml(value.link);
});
Using Safe Contextual Escaping (docs.angularjs.org/api/ng/service/$sce) and using trustAs delegate you're telling Angular that this value is safe to use within that context. In this example. $sce.trustAsHtml returns an object that angular can trust is safe to as HTML.
In the first case, you'll actually want to use:
<p data-ng-repeat='i in links' >{{ i.link }}</p>
Double braces, not brace-dollar. In the second case, ng-bind-html will require that you have added "ngSanitize" to your module's dependency list.
angular.module('yourAppNameHere', ['ngSanitize'])
Edit:
If you really do want clickable links on the page, then do pretty much what #sreeramu suggested (Though I'd see if you can't find a way to add a nice description):
<p data-ng-repeat='i in links' ><a ng-href="{{i.link}}">{{i.desc}}</a></p>
(Notice that he suggested using ng-href, instead of href. He's right.)
Insert ngSanitize as a dependency to you app:
angular.module('myApp', ['ngSanitize'])
But before be ensure that you are including the script angular-sanitize.js.
Good luck!
It might be that your links have already got the a tags with it so in this case you do not need to re-add the a tags...
In this case do this...
Add this to you scripts (include acc. to your angular version)
<script type="text/javascript"
src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.5/angular-
sanitize.min.js"></script>
Add this to your app.js
var app = angular.module('modulename', [ 'ngSanitize']);
And than in your view do this
If it is the div that you want the link to attach to...
<div ng-bind-html="i.link"></div>
The above would give you something as this
<div><a href='your link'></a></div>
I am trying to initialize $scope.selectedModel to model1with ng-init. However, the following HTML fails to accomplish this:
<div class="productImage">
<div class="imageGallery" ng-init="selectedModel='model1'">
<div ng-repeat="mod in pTab" ng-if="modelIsActive(mod)">
<div ng-repeat="img in mod.galleryImages">
<img class="overviewProductImage" ng-src="{{img.image}}" ng-if="productImageIsActive(img, $index)"/>
</div>
</div>
</div>
</div>
And here's the modelIsActive method that uses selectedModel:
$scope.modelIsActive = function (tab) {
return tab.model== $scope.selectedModel;
}
Eventually I will want to use ng-init="selectedModel= mod.model" but when that didn't work I substituted the simple string 'model1' and found it still wasn't initializing selectedModelto that string.
How can I use ng-init to set $scope.selectedModel? Or should I be using something else? Do I need to use $watch or something similar?
If you can, it is better to initialize your selectedModel in your controller rather than in the HTML using ng-init: this directive can have exepected behaviors.
If you really need to though, you either need to at least define $scope.selectedModel in your controller and then set a value in the ng-init, or use an object instead of directly a value, such as
<div ng-init="model.selectedModel = 'model11'">
(but you'll still need to initialize $scope.model in your controller)
please put your ng-if into the inner of repeat:
<div ng-repeat="mod in pTab">
<div ng-repeat="img in mod.galleryImages" ng-if="modelIsActive(mod)">
I'm using AngularJS with a third party service that generates html responses. I want to use ng-repeat to render the HTML responses as a list, however Angular renders it as text.
Is it possible to use ng-repeat to render HTML property?
I've created this jsFiddle to demonstrate my issue.
http://jsfiddle.net/DrtNc/1/
I think using ng-bind-html-unsafe will get you what you need.
<div ng:repeat="item in items" ng-bind-html-unsafe="item.html"></div>
Here's a working fiddle: http://jsfiddle.net/nfreitas/aHfAp/
Documentation for the directive can be found here: http://docs.angularjs.org/api/ng.directive:ngBindHtmlUnsafe
The way I achieved this is by ng-bind-html inside the ng-repeat;
<div ng-repeat="comment in comments">
<div ng-bind-html="comment.content"></div>
</div>
Hope this helps someone!
item.html will always be interpreted as text. you have to convert it to html explicitly. click here
I have added a render function which will convert each string to html.
