Get context path in every embedded forms.

[Emerald Hieu]

Hi,

Following this guide, I'm trying to get context path using AngularJS. Based on that context path, I include a JS file that contains JQuery scripts.

The problem is the JS file has been included but the script doesn't run. I wonder if the merging of AngularJS and JS caused the problem.

1) Can I use JQuery $.ajax() to get the context path? If so, what's the rest engine URI should I pass? How can I do it if I don't have a context path to prepend it to "engine-rest/engine/default/task/.../form"?

2) Do every pages must include this script to get context path before including <script>, <link> or <img>? Is there a way to reuse it?

test.html

<form role="form" class="form-horizontal">

<script cam-script type="text/form-script">

inject(['$http', 'Uri', function($http, Uri) {

camForm.on('form-loaded', function() {

$http.get(Uri.appUri("engine://engine/:engine/task/" + camForm.taskId + "/form")).success(function(result){

$scope.contextPath = result.contextPath;

});

});

}]);

$scope.getPath = function (path) {

  return $scope.contextPath + path;

};
</script>

<script type="text/javascript" ng-src="{{getPath('/resources/js/my-app/test.js')}}"></script>

</form>

Inspect Element, it gives

<script type="text/javascript" ng-src="/my-app/resources/js/test.js" src="/my-app/resources/js/test.js"></script>

test.js

alert('something');

Hi,

we believe that it is not a really good thing to load additional scripts from the form itself.
If you need additional scripts, you should rather customize the build (it can be done in multiple ways, the easiest one seems to just add a script tag at the end of the index.html).

A client asked for something similar and we are working on a example. I will keep you in touch.

All the best,

And here it is:

Will only be possible with camunda 7.3.0, however.

I found this post when searching for the same thing.

As far as I understand I currently CANNOT load additional scripts in a task form - correct?

I think this IS a valid use case - as anything else means you need to adjust the overall tasklist, which might not be possible - but you still want to add new stuff in your own task form (which is part of the process application deployment - not the tasklist deployment itself).
