Hook for parsing Angular.js templates

I'm curious if Angular has a template parsing hook that can be used globally or within specific controllers.

My goal is to create a language and device-specific theme loader that can dynamically retrieve resource links (such as img tags and inline styles) and redirect them to the appropriate resources.

For instance, let's say someone has implemented a template displaying an image:

<img src="images/my-super-image.jpg">

Now, I want to modify the template and change the resource to its language-specific equivalent:

<img src="theme/en_us/lowres/my-super-image.jpg">

Here are key points for me:

  • The template creator shouldn't worry about themes; they just use the resource as shown in the initial example.
  • I prefer not to use a directive but rather have a global solution specific to the app—ideally incorporated into the app's run function.
  • I aim for a highly dynamic approach without relying on lookup tables for resources.

Currently, I'm unsure of where to place a parse hook function like this one or how to access the templates being used on a page before Angular renders them to the DOM.

I've resorted to a somewhat messy workaround, which I'm not satisfied with because it only applies after templates have been rendered:

$(document).bind('DOMNodeInserted', function(event) {

  if(angular.isDefined(event.originalEvent.originalTarget.innerHTML)) {
    event.originalEvent.originalTarget.innerHTML = String(event.originalEvent.originalTarget.innerHTML).replace('src="images','src="' + imgPath);
  }
});

Do you have any suggestions on how to achieve this? Thank you all!

By the way, I'm new to Angular, so detailed explanations would be greatly appreciated. Thanks again!

To modify the DOM in Angular, you can utilize a directive. Here's an example:

app.directive('myApp', function() {
return {
restrict: 'A',
replace: true,
link: function(scope, element, attrs) {

},
compile: function(tElement, tAttrs, transclude) {
tElement.find('img')[0]['src'] = "theme/en_us/lowres/" + tElement.find('img')[0]['src'].split('/')[tElement.find('img')[0]['src'].split('/').length - 1];
 }
 };
 });
