jquery - Javascript: Open PDF in new tab from byte array

Question

I'm using AngularJS with an HTTP resource to call an external API and my response is a byte array. I need to turn this byte array into a PDF in a new window. I haven't seen any very good solutions on here that work cross browser or that are pure javascript. Is there a way to do this?

Here is my code:

Javascript

Document.preview({id: $scope.order.id}, function(data){

    // Open PDF Here
    var file = new Blob([data], {type: 'application/pdf'});
    var fileURL = URL.createObjectURL(file);
    window.open(fileURL);

});

Answer 1

You would need to pass the responseType in your service call

$http.post('/Service-URL', dataTO, {responseType: 'arraybuffer'});

then in the success of your data call this should open up pdf in a new window:-

    getDocument()
        .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            var fileURL = URL.createObjectURL(file);
            window.open(fileURL);
    })
