Javascript – HTML5 video player prevent seeking

htmlhtml5-videojavascript

I'm creating a series of video tutorials and would like to prevent users from seeking forward and skipping sections. I'll be using an HTML5 video player that will be used for desktop and iPad browsers. Ideally, I'd like this to work on the iPhone as well, but I realize you have no control over the video on the phone since it uses the iPhone video player.

How can I prevent users from seeking forward on an HTML5 video player?

Another example for Video.js:

videojs('example_video_1').ready(function(){
  var player = this;
  var previousTime = 0;
  var currentTime = 0;
  var seekStart = null;

  player.on('timeupdate', function(){
    previousTime = currentTime;
    currentTime = player.currentTime();
  });

  player.on('seeking', function(){
    if(seekStart === null) {
      seekStart = previousTime;
    }
  });

  player.on('seeked', function() {
    if(currentTime > seekStart) {
      player.currentTime(seekStart);
    }
    seekStart = null;
  });
});

Javascript – How to prevent buttons from submitting forms

You're using an HTML5 button element. Remember the reason is this button has a default behavior of submit, as stated in the W3 specification as seen here: W3C HTML5 Button

So you need to specify its type explicitly:

<button type="button">Button</button>

in order to override the default submit type. I just want to point out the reason why this happens.

Javascript – Storing Objects in HTML5 localStorage

Looking at the Apple, Mozilla and Mozilla again documentation, the functionality seems to be limited to handle only string key/value pairs.

A workaround can be to stringify your object before storing it, and later parse it when you retrieve it:

var testObject = { 'one': 1, 'two': 2, 'three': 3 };

// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));

// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');

console.log('retrievedObject: ', JSON.parse(retrievedObject));
