Use a variable to add the costs of premium features that are selected or deselected using an iOS switch component. See a video of how to do this step-by-step in this webinar: https://support.proto.io/hc/en-us/articles/115001585411-Model-advanced-prototypes-that-use-variables-part-II TAGS: variables variable math addition switch switches fire an items event

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.

Hey guys! I'm back with an amazing prototype for you guys. This has been my longest and quite a challenging redesign project for IMDb whose prototype is pretty awesome and contains lots of stuff like Nested Containers, a bit of animation, some really beautiful visual elements and interactivity for you to explore! I had so much fun making it with Proto.io and I truly hope you guys love it and would love to know your views and suggestions on how can I improve it :) Cheers! Aman

Here is a prototype of a music player. Click play and add different sort of beats to the audio. Sample audio is from http://tricoolore.com/ Enjoy!

For my User Experience & Visual Design class we had to redesign the entire website for a bookstore called Laie that is based in Barcelona. This is desktop proposal. It's my first time using proto.io! Feedback is more than welcomed! I'm a 3rd year Graphic Design student from Barcelona. cristinanitrons@hotmail.com

3 prototypes showing different uses of the form components for iOS 1) Activate / de-activate button when checking / un-checking Terms of Service 2) Capture text input to change property 3) Change number of tickets - limit 8 See how they were created step-by-step in the Using Forms webinar video: https://vimeo.com/118919393 This version on Vimeo includes time-codes so you can jump to particular sub-sections (repeated below as a preview): > Range of iOS form input controls 2:02 > Labels 2:17 > Text fields 2:32 > Setting placeholder text 3:04 > 5 Input Types that display the appropriate iOS keyboard (Text, Numeric, Email, Password, Telephone) 3:30 > Using the Telephone keyboard for credit card number input (large # keys) 4:08 > Need to view prototype on device in order to see the range of keyboards 5:59 > Multi-line text area input field 6:24 > Search Bar 6:40 > Checkbox control customization 7:22 > On/Off Switch control customization 7:52 > Slider control customization 9:27 > Increasing size of slider handle 9:47 > Picker Wheel Customization 10:00 > Prototype example: Activate button when checking terms of service 10:42 > Create a button with two states (using convert to container) 12:55 > Adding interactions to a checkbox control (on change activation/deactivation) 14:45 > Definition of variable and range of uses 17:04 > Using variables with text field interactions 18:25 > Prototype Example: Using a variable to capture text input and show it in a different text box using change property. 23:27 > Prototype: Use variables to increment and decrement counter showing number of tickets being purchased. 28:40 > Searching full range of icons built into Proto.io 29:10 > Using a variable to limit the range of tickets (0 to 8) 32:46 > Copying and pasting interactions with Variables 40:08
