Dynamically set value of a file input [duplicate]

Answer 1

I ended up doing something like this for AngularJS in case someone stumbles across this question:

const imageElem = angular.element('#awardImg');

if (imageElem[0].files[0])
    vm.award.imageElem = imageElem;
    vm.award.image = imageElem[0].files[0];

And then:

if (vm.award.imageElem)
    $('#awardImg').replaceWith(vm.award.imageElem);
    delete vm.award.imageElem;
