问题 There has been an error, in the console, since I made my website using navigator.geolocation.getCurrentPosition (below). I realised this was going to cause a problem at some point in the future, and as I'm only playing with web development it didn't concern me that much, but it has now completely screwed up my little weather app (http://conn3cted.uk.tn/weather.html) as it seems that I can't use this function in chrome (it works in firefox) anymore.

问题 I have adapted the following webpage to my needs and added a bit of code so it now has select2 dropdown menus instead of regular select menus (which I like a LOT better).

问题 I have a menu bar who's class I want to change after a users scrolls to the next div, the div is 100vh tall. The function below works only with screens my size, anything smaller or bigger the animation will go to early or too late. How do I make the units that this function uses vh? Thanks $(window).scroll(function() { var scroll = $(window).scrollTop(); if (scroll >= 600) { <---- change to vh units not px----- $(".home").removeClass("open"); } 回答1: 100vh is the actual view height of that

问题 I have a Select2 Box, with tagging enabled to add new own tags. Selecting an existing option works without any problem (of any length). But some code prevents me from adding a new option longer than 2 characters long (just can't add more characters). See the JSFiddle <select class="form-control select2" multiple="multiple" id="employee-groups-select" name="employee[employee_group_ids][]"> <option value="4">Text1</option> <option value="1">Text2</option> <option value="3">Text3</option>
