I am new to salesforce coding and i am having a requirement:
I have one text field on my visualforce page where a user will put youtube URL and there is a preview button on click of which he should be able to see the preview of the video on the same page without saving it to database.After he is done with preview there is a save button on click of which he should be able to save it(by save i mean save the Youtube URL) to  some object.I explored and came to know salesforce provide preview feature only for the file attached through feeder which gets stored in content document object but since my video size can be large in size I dont want to go by that way of previewing a video.Can some one please suggest any solution or code examples to do this.Thanks In advance.
