I'm playing some experiments using AngularJS and Leaftlet (I'm new at both of them). I see I can specify some HTML as markers.bindPopup(...); parameter. Does anyone tryied to show an AngularJS directive as parameter? I tryed this way whit no success (no surprise) bindPopup(<myDummyDirective></myDummyDirective>). I want to show my directive as marker's popup, is there a way to do this?
Use $compile:
Compiles an HTML string or DOM into a template and produces a template function, which can then be used to link scope and the template together.
$compile('<myDummyDirective></myDummyDirective>')(scope);
See the reference: https://docs.angularjs.org/api/ng/service/$compile

I have a one-page site that I am building out and this is my first time using Angular on a site. Building it on top of Laravel too for the backend but that is beyond the scope of this question.
I need to be able to open a modal on a main page view which will add a new resource (e.g. a new client) or edit a resource. I want to somehow get the form's html inside the modal body when the $uibModal.open()'s controller is called and set the $scope.modalBody equal to the injected items.modalBody (the only way this works is if I use:
$scope.modalBody = $sce.trustAsHtml(items.modalBody);
The only problem now is that anything inside the HTML body, Angular will not use it's magic and do any data-binding. It is still in the raw form of
{{ object.property }} or since I'm using Laravel and avoiding conflict with the Blade template engine:
<% object.property %>

I have been banging my head against the wall on this one...I have tried putting $scope.$apply() in my directive and my controller, neither of which worked. I have a feeling that is the source of my problem though. I have also tried making the html just a <new-client></new-client> directive and using templateUrl: 'views/clients/add.php' which would be ideal, but the template is not being included inside the <new-client></new-client>.
I'm using ui-bootstrap 0.14.3 and Angular 1.4.8.
Could this be a bug? Or am I doing something wrong? Anyone have a better way of getting a form into my modal? Let me know what code you want to see so I don't clutter this post with unnecessary code blocks.
I have come across a similar issue with using jQuery's AJAX to receive template strings and append it to a server.
So when HTML is added via jQuery, bound html string, etc., angular doesn't know it needs to automagically compile this data.
What you need to do is use the $compile service, to $compile your html and then attach the correct $scope to it:
`$compile('jQuerySelectorReturningHtmlOrAnHTMLStringThatNeedsToBeCompiled')($scope);`
There are multiple examples in Angulars Documentation for $compile that can give you an idea of what is happening. I think by what you have described the same thing is happening here in your situation.
The key is to call this $compile service function after the html has been bound to the page.
EDIT:
There are a few other options based on some comments, that will serve as a viable solution to rendering this content on your view. For example a directive that takes a string attribute representing the HTML string of your desired view.
1. Modify your directive template in the compile step:
You have the ability to modify your template before the directive compiles and binds any attributes to it, to that directives scope:
app.directive('myAwesomeCompileStepDirective', [myAwesomeCompileStepDirectivef]);
function myAwesomeCompileStepDirectiveFn() {
return {
restrict: 'EA',
compile: function compileFn(tAttrs, tElement) {
//Here you can access the attrs that are passed into your directive (aka html string)
tElement.html(tAttrs['stringThatYouWantToReplaceElementWith']);
return function linkFn(scope, element, attrs, controller, transcludeFn) {
//if all you want to do is update the template you really don't have to do anything
//here but I leave it defined anyways.
}
}
}
}
You can view a file I wrote for a npm component which uses this method to modify my directive template before it is compiled on the page & you can also view the codepen for the complete component to see it in action.
2. Use $compile service to call $compile in link function using directive attrs.
In the same way as the aforementioned method, you can instead inject the $compile service, and call the function mentioned above. This provides a bit more work, for you but more flexibility to listen to events and perform scope based functions which is not available in the compile function in option 1.
Using jQuery, it's easy to replace the innerHtml of a single div, either with content from the elsewhere in the HTML, from a JavaScript var, or from an HTTP call.
How can I do that in AngularJS (without using jQuery)? For example, to keep a page the same, but only replace a side panel?
Try using ng-view / ui-router . More details :
https://docs.angularjs.org/api/ngRoute/directive/ngView
angular-ui/ui-router, how do I inject partial view using $stateProvider?
It seems the answer is: "Think twice if you need to do this." In Angular, the paradigm isn't to modify the HTML, but rather to bind the HTML. So, bind the div's src to a scope or controller var via ngInclude, and just change that var.
I have jsonData which consist of HTML content. I want to render that HTML in ng-grid. The content is not rendered however -- it only shows up in normal string format.
Below is the plnkr which shows all the code:

There's a few things going on here:
Not related to your exact issue, but you've got nested single quotes in your firstName field. You need to do some escaping or your ng-click expression is going to break. So instead of ng-click='show('F:/cox/main.html')' you can do ng-click=\"show('F:/cox/main.html')\".
Also not related to your exact issue, but if you want to access properties on your controller's scope from inside UI-Grid you need to use appScope. The docs on it are here: http://ui-grid.info/docs/#/tutorial/305_appScope
The main problem with getting HTML provided from inside your app to render is Strict Contextual Escaping.
Strict Contextual Escaping (SCE) is enabled by default in Angular and escapes any arbitrary HTML to prevent things like XSS and clickjacking. In order to get your HTML to show up you need to trust it, and bind it with an HTML bind expression.
You can use the $sce service to trust the HTML. Just iterate over your rows and do $sce.trustAsHtml(row.firstName). (You can read more about SCE here: https://docs.angularjs.org/api/ng/service/$sce) Then you will need a custom cell template to bind the HTML. The simplest one looks like this:
<div class="ui-grid-cell-contents" ng-bind-html="COL_FIELD"></div>
COL_FIELD will get transformed by UI-Grid into the proper binding for your field. Now the problem is that your ng-click directive doesn't get compiled. You need to use a directive that will take your custom HTML and compile it. You could roll your own, or use something like this library to do it for you: https://github.com/incuna/angular-bind-html-compile
The main thing to keep in mind is being able to actually trust the source of your HTML. If you can't be sure then going about this another way (i.e. by not providing HTML inside your data set) would be better.
I've modified your plunker to show all this working together: http://plnkr.co/edit/MgLoeGBoRTi2fF3e6pia?p=preview
I'm using a custom jquery plugin which transforms table to a tree. And when i'm loading data from ng model i need to recall plugin's constructor. but i can not find that event, when i need to call that.
I've tried to $watch model variable - doen't work well
You should create a new directive instead of doing this in a controller.
By using a directive, you'll be sure that the code located in its link function is applyed after DOM complilation.
It is intended to do what you want.
see http://docs.angularjs.org/guide/directive
I have the following line in my html:
<div ng-bind-html-unsafe="departmentConfig" class="control-group"></div>
and I use a $resource get to retrieve the HTML, assign the HTML to $scope.departmentConfig, and then the view is updated perfectly. The HTML that is assigned to $scope.departmentConfig contains form elements, with ng-model attributes in it, but when I change the values in these input elements, they don't update the $scope model at all.
This is what I have tried, based on a lot of other internet posts, and it isn't working:
$resource('resources/sources/departments/:mappedName', {
mappedName:departmentKey
}).get(function(departmentConfig) {
// This will call another function that will build a chunk of HTML
$scope.departmentConfig = $scope.buildDepartmentConfigHtml(departmentConfig);
// This is my feeble attempt to access the element, and bootstrap it to include the items in the $scope model.
var $departmentConfigContainer = $('#departmentConfig');
angular.bootstrap($departmentConfigContainer, ['sourcemanager']);
I have even seen some jsFiddle examples where this appears to be working, but mine isn't. Am I calling bootstrap too soon? I also tried putting a $watch on $scope.departmentConfig like this:
$scope.$watch('departmentConfig', function() {
var $departmentConfigContainer = $('#departmentConfig');
angular.bootstrap($departmentConfigContainer);
});
but it didn't work either. I bet there is an easy explanation to this, I just can't seem to get the input elements with ng-model that are loaded after page compile to get bound to the model. Any help is appreciated, this is the last piece of functionality I need to get working on my page. Let me know if you need more information about my configuration as well.
So, simply put, how can I force a section of the DOM to recompile after I know it has been loaded?
UPDATE
Here is a jsfiddle outlining what I would like to do: http://jsfiddle.net/j_snyder/ctyfg/. You will notice that property two and three don't update the model, and I am calling bootstrap on the outer div, hoping that will include those in the model binding. This is the first time I have posted to jsfiddle, please let me know if you can't see the example.
ng-bind-html is made for regular HTML, not compiling new angular elements.
You will have use the $compile service.
Here is how you would edit your current example to work: http://jsfiddle.net/andytjoslin/ctyfg/21/. But this way ends up being bad, because you have to do DOM manipulation in your controller.
You just need to create a directive that will basically do what you wanted ng-bind-html to do: http://jsfiddle.net/andytjoslin/ctyfg/22/
