     if (this.files[1]!=null){

         this.removeFile(this.files[0]);

     }});

      this.on("complete", function () {

        previewFileBtn = document.createElement('button');

        previewFileBtn.id = "previewFileId";

        document.querySelector("#theFile").append(previewFileBtn);

        var rt = document.createTextNode("preview the file ");

        var name = this.files[0].name;

        console.log("name =",name);

        previewFileBtn.appendChild(rt);

        document.body.appendChild(previewFileBtn);

        previewFileBtn.onclick = function (){console.log("preview file Clicked");

        window.location.href = "{{ url_for('readpreview', name=name )}}";

        }});





      var readButton = document.querySelector('#read');

      myDzRead = this;

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          mat-slide-toggle shouldn't change it's state when I click cancel in confirmation window

          Image
          1 When I checked the slide toggle it should work as expected. But when I try to uncheck it there is a confirmation window asking if you are sure. When I click cancel in that confirmation window, still the toggle changes to unchecked, which shouldn't happen. It should stay in the same state. Here is my Html and TS Code // html <mat-slide-toggle (change)="change($event)" [checked]="isChecked()" > To-pay </mat-slide-toggle> TS code: // ts change(e) { if(this.checked) { if(confirm("Are you sure")) { console.log("toggle") } else { e.stopPropagation(); console.log("toggle should not change if I click the cancel button") }
