ı am trying to create a title property for my recording. When ı type the name of the recording, if it's first on the list the title property became blank. After creating the second recording and typing the name it gets the title of the previous recording object. Tried to change the calling order of the modal function in stopRecording function, but it didn't work. I hope you can help. My code is not clean for now ı will arrange it later, please ignore it

CodePudding user response：
The problem with your current code is that in your stopRecording() function, you tried to get the title by having the user key in the name from the modal but it will not work because that portion is synchronous meaning that the code below setModalVisable will already have ran before the user can even input a title. To fix this you must first get the user to key in the title before the recording can be saved.
I have modified the code to fix the issue.
