Display images from firebase storage in html img tags

I'm attempting to display an image from firebase into html img tags, but it fails to retrieve the image.

Javascript code: 

var storageRef = firebase.storage().ref();
var spaceRef = storageRef.child('images/photo_1.png');
var path = spaceRef.fullPath;
var gsReference = storage.refFromURL('gs://test.appspot.com')

storageRef.child('images/photo_1.png').getDownloadURL().then(function(url) {
  var test = url;
}).catch(function(error) {

});

html code: 

<img src="test" height="125" width="50"/>

This is a neat way to load the images if you know the filenames in advance:

https://firebasestorage.googleapis.com/v0/b/{{BUCKET}}/o/images%2{{FILENAME}}?alt=media

Remove the ?alt=media to get some metadata.

This is a well-tested code. it is working fine. just follow these steps.

html code:

<img id="myImgId" src="" height="125" width="50"/>

Add config Information here

  con = {
        "apiKey": "your key",
        "authDomain": "example.firebaseapp.com",
        "databaseURL": "https://example.firebaseio.com/",
        "projectId": "example",
        "storageBucket": "example.appspot.com",
        "messagingSenderId": "id"
    };

Initialize firebase using this

firebase.initializeApp(con);

Create a reference with an initial file path and name

var storage = firebase.storage();
var storageRef = storage.ref();
//urll is the url for image
storageRef.child(urll).getDownloadURL().then(function(url) {
  // Or inserted into an <img> element:
  var img = document.getElementById('myImgId');
  img.src = url;
}).catch(function(error) {
  // Handle any errors
});

           var uploader=document.getElementById('uploader'),
           fileButton=document.getElementById('fileButton');

           fileButton.addEventListener('change', function(e) {

           var file=e.target.files[0];

           var storageRef=firebase.storage().ref("'/images/'"+file.name);


            var task=storageRef.put(file);

            task.on('state_changed',

            function progress(snapshot){
            var percentage=( snapshot.bytesTransferred / snapshot.totalBytes )*100;
            uploader.value=percentage;
            if (percentage==100){
            alert("file uploaded Successfully");
            }
            },
            function error(err){

            },
            function complete(){

                 var text1=document.getElementById('text3');
                 var text7=document.getElementById('text4');
                 var text8=document.getElementById('text5');
                 var text9=document.getElementById('text6');

                var downloadURL =task.snapshot.downloadURL; 
                var postkey=firebase.database().ref('data-modeling/').push();
                var text2=text1.value;
                postkey.child("Name").set(text2);
                var texta=text7.value;
                postkey.child("Address").set(texta);
                var textb=text8.value;
                postkey.child("Age").set(textb);
                var textc=text9.value;
                postkey.child("PhoneNo").set(textc);
                postkey.child("url").set(downloadURL)
                alert('successful Submit');




             });

            }


        );

The bellow two lines which is commented are not required, I have tested. it is working fine.

//var path = spaceRef.fullPath;
//var gsReference = storage.refFromURL('gs://test.appspot.com')

    <script>
     function showimage() {



         var storageRef = firebase.storage().ref();
         var spaceRef = storageRef.child('sweet_gift/vytcdc.png');
         storageRef.child('sweet_gift/vytcdc.png').getDownloadURL().then(function(url) {
             var test = url;
             alert(url);
             document.querySelector('img').src = test;

         }).catch(function(error) {

         });


     }
    </script>
    <input type="button" value ="view Image" id="viewbtn" onclick="showimage();">
    <img src="test" height="125px" width="200px"/>

//var storage    = firebase.storage();
//var storageRef = storage.ref();
//var spaceRef = storageRef.child('images/photo_1.png');
//
//storageRef.child('images/photo_1.png').getDownloadURL().then(function(url) {
//
//
//  var test = url;
//  add this line here:
//  document.getElementById("your_img_id").src = test;
//
//}).catch(function(error) {
//
//});
//

<img height="125" width="50" id="your_img_id" src=""/>

Once you have the test variable, you need to set the image's src to it using a script.

Something like this:

//var storage    = firebase.storage();
//var storageRef = storage.ref();
//var spaceRef = storageRef.child('images/photo_1.png');
//
//storageRef.child('images/photo_1.png').getDownloadURL().then(function(url) {
//
//
//  var test = url;
//  add this line here:
//  document.querySelector('img').src = test;
//
//}).catch(function(error) {
//
//});
//
var test = 'firebase_url';

document.querySelector('img').src = test;
<img height="125" width="50"/>
