Can anyone

问题 Can i use jquery (or javascript) to force an html5 video player to play in picture in picture mode?(image below) . This is for my personal site on which i'm using jquery 3.3.1 (hosted by Google).

This is my code so far: <video id="player"> <!-- source --> </video> <script> player = $('#player')[0]; var player = $('#player')[0]; $(window).keydown(function(e) { switch(e.which){ case(32): if(player.paused){ player.play(); } else{ player.pause();

问题 I have from and to input fields with bootstrap date picker. When query params not empty I would like to change the value of these input fields and trigger the change date event on datepicker because I have a function that calculates total price between dates. When user selects dates from datepicker works fine but if I change the value by jquery it does not calculate. $('#from').val('<%= @from_date %>').trigger( 'change' ); $('#to').val('<%= @to_date %>').trigger( 'change' ); //function var

问题 I am trying to create an Excel AddIn with JavaScript API. But I don't understand where "console.log" outputs their messages. All Microsoft documentations are full with console.log examples, but it is not explained where console.log() outputs the messages.

I have searched the web. I have searched through all
