        background-repeat: no-repeat;
        background-position: center;
    }
}
}

JS ................

function readURL(input) {
 if (input.files && input.files[0]) {
    var reader = new FileReader();
    reader.onload = function(e) {
        $('#imagePreview').css('background-image',      'url('+e.target.result +')');
        $('#imagePreview').hide();
        $('#imagePreview').fadeIn(650);
    }
    reader.readAsDataURL(input.files[0]);
 }
}

$("#imageUpload").change(function() {
    readURL(this);
});

How can I use it in angular 6?

Here is the link where I get this, someone please help me.

Answer 1

For typescript it is something like this.

<input type="file" id="upload-photo" style="display: none" (change)="onSelectFile($event)" />

    onSelectFile(event: any) {
        if (event.target.files && event.target.files[0]) {
            const reader = new FileReader()

            reader.onload = (ev: any) => {
                this.person.photo = ev.target.result
            }
            reader.readAsDataURL(event.target.files[0])

        }
    }

And to show in HTML only you write two way data binding for that.
