Note

This code is missing the commonServices.getFileObject code referenced in line 3.

function link($scope, $elem) {
    function download() {
        commonServices.getFileObject($scope.fileId, $scope.moduleId).then(result => {
            let blob = new Blob([result.data]),
                disposition = result.headers['content-disposition'].replace('attachment; ', ''),
                filename = disposition.split('=')[1];


            if (window.navigator && window.navigator.msSaveOrOpenBlob) {
                //Open file IE
                window.navigator.msSaveOrOpenBlob(blob, filename);
            } else {
                //Open file browser other than IE
                let a = document.createElement('a');


                a.style.display = 'none';
                document.body.appendChild(a);
                a.href = window.URL.createObjectURL(blob);
                a.download = filename;


                window.setTimeout(() => {
                    a.click();
                    document.body.removeChild(a);
                }, 500);
            }
        });
    }


    $elem.on('click', download);


    $scope.$on('$destroy', function () {
        $elem.off('click');
    });
