How to detect in javascript if a Smart Banner App is currently displayed?

Question

I want to detect in Javascript if a Smart App banner is currently displayed. I already inspected the DOM but there is no evidence of the banner.

Answer 1

This is an old question, but maybe this will be useful to someone. I did this in a following way:

1. Detected iOS user-agent;
2. Used window.matchMedia to determine device type and orientation with media queries;
3. Checked window.innerHeight

After my experiments I have following experimental window.innerHeight values for different devices with banner shown. You can find them below:

• iPhone 6 Plus portrait: 544px;
• iPhone 6 Plus landscape: 286px;
• iPhone 6 portrait: 475px;
• iPhone 6 landscape: 247px;
• iPhone 5 & 5S portrait: 376px;
• iPhone 5 & 5S landscape: 148px;
• iPhone 2G, 3G, 4, 4S, iPod Touch generations 1-4 portrait: 288px;
• iPhone 2G, 3G, 4, 4S, iPod Touch generations 1-4 landscape: 148px.

Hope this will help someone.
