Should Javascript scrollIntoView() vary on different browsers? - javascript

HTML & Javascript example with a hash tag in the URL. The script will locate an element with text of the value of the hash tag as there is no element with the corresponding ID attribute then scoll to that element. This works on Firefox.
Is there a reason it should not work on Chrome?
<!DOCTYPE html>

<script>
if (bare_hash = window.location.hash?.substring(1)){
window.onload = function(){
function get_element_by_content (bare_hash_a, tag_a){
return Array.from(document.getElementsByTagName(tag_a)).find(e_a=>e_a.innerText.includes(bare_hash_a));
}
get_element_by_content(bare_hash, "h1")?.parentNode.scrollIntoView();
}
}

angular js Bootstrap not working with multiple rows and columns

I am making a basic blackjack game with angularjs and using bootstrap for the layout however I cannot seem to make it work.
What I want is a heading across the top, the content of the game in the middle and left and a list of current players on the right but isn't everything is running down the page.
My code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Blackjack</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<script src="./angular.js"></script>
<script src="./angular-animate.js"></script>
<script src="./angular-touch.js"></script>
<script src="./ui-bootstrap.js"></script>
<script src="./app.js"></script>
</head>
<body ng-app="myApp">
<div class="container-fluid" ng-controller="main">
<div class = "row">
<div class="col-sm-12">
<h1>Black Jack</h1>
</div>
</div>
<div class="row">
<div class = "col-sm-10">
<div ng-include="'play.html'" my-replace>
</div>
<div ng-include="'next.html'" my-replace>
</div>
<div ng-include="'start.html'" my-replace> </div>
</div>
<div class="col-sm-2">
<ul class = "row">
<li class="col-sm-12">
<h2>Players</h2>
</li>
<li class = "col-sm-12" ng-repeat="player in players">
<span>{{player.name}}: <button ng-if="!started" ng-click='removePlayer(player)'>Remove</button></span>
</li>
</ul>
</div>
</div>
</div>
<!--
<script src = "https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.js"> </script>
<script>
div = $("div");
(function add(div){
div.each(function(i, val){
this.innerHTML=this.nodeName+" open "+this.className+" "+this.innerHTML+" "+this . nodeName+" close"
add($(this).children());
})})(div);
</script>
-->
</body>
</html>
The my-replace directive strips away the wrapping div of the ng-includes once their content loads.
The js code at the bottom is a quick debugger so I can see how the html was being interpreted as firebug light doesn't work with angularjs.
I've tried with multiple versions of bootstrap too
Why isn't the bootstrap working?

What is wrong with this nodeValue replacing code?

I am learning basic js operation on DOM, and it works fine with the first part of the code, which completes attributes replacing function.
Then it doesn't work with the second part code, which needs to replace the null value of the childNode.nodeValue of the "p" element.
I checked lots of times in the past 2 hrs, and the whole structure is also the same with the code in the book, but it just won't work.
I also checked the MDN about the node related entries, but also failed to get what is going on here.
gallery.js
function showpics(indexs){
var linky = indexs.getAttribute("href");
var holdy = document.getElementById("holder");
holdy.setAttribute("src",linky);
var texty = indexs.getAttribute("title");
var fun = document.getElementById("funnyWords");
fun.childNodes[0].nodeValue = texty;
}
Below is the HTML file
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" http-equiv="IE=Edge,chrome=1">
<title>YTimes</title>
<script type="text/javascript" src="gallery.js"></script>
</head>
<body>
<h1>Our Story</h1>
<section>
<ul>
<li>F</li>
<li>2.0</li>
<li>Riverrun</li>
</ul>
</section>
<section>
<p id="funnyWords"></p>
<span>
<img src="" alt="" id="holder">
</span>
</section>
</body>
</html>
The problem is that #funnyWords has no content:
<p id="funnyWords"></p>
Therefore, fun.childNodes[0] is undefined.
You can create a new text node if necessary:
if(fun.childNodes.length)
fun.childNodes[0].nodeValue = texty;
else
fun.appendChild(document.createTextNode(texty));
Alternatively, new browsers support textContent:
fun.textContent = texty;
<head>
<meta charset="UTF-8" http-equiv="IE=Edge,chrome=1">
<title>YTimes</title>
<script type="text/javascript" src="gallery.js"></script>
</head>
<body>
<h1>Our Story</h1>
<section>
<ul>
<li>F</li>
<li>2.0</li>
<li>Riverrun</li>
</ul>
</section>
<section>
<p id="funnyWords">
<div class="childnode">
</div>
</p>
<span>
<img src="" alt="" id="holder">
</span>
</section>

Javascript function not running with no errors

here is my function which is put into its own file(Javascript/submitDate.js):
document.onload = function(){
function submitDate(){
var time = new Date();
var nowDate =time.toISOString().slice(0,-14);
document.getElementById("dateShow").value=nowDate;
}
submitDate();
}();
This ran fine before I joined the page with my index.(When I put all my javascript and page layout into one file)
Here is the page(projectMain.html) of the code:
<html>
<div id="container">
<header>
<h3>Entries close on the 10th of March</h3>
</header>
<section>
<aside onload="submitDate();">
Last submitted:
</br>
<input type="date" id="dateShow" readonly>
</aside>
</section>
No errors pop up and it just shows the date layout box as: mm/dd/yyyy
EDIT:
The folder has a capital J.
Edit 2.0:
Link to what is shown. Underneath the "last submitted" is the date function that is not working. : http://prntscr.com/60ie8k
Edit 3.0:
Here is my Index:
<html>
<head>
<title>Sample Template</title>
<link rel="stylesheet" language="text/css" href="CSS/stylesheet.css"/>
<script language="javascript" src="Javascript/AJAX.js"></script>
</head>
<body onload="javascript:changePage('home');">
<h1>Little Big Planet</h1>
<div class="menu">
<a onclick="javascript:changePage('home');">Home</a>
<a onclick="javascript:changePage('powerups');">Power Ups</a>
<a onclick="javascript:changePage('bots');">Sackbots</a>
<a onclick="javascript:changePage('costumes');">Costumes</a>
<a onclick="javascript:changePage('projectMain');">Form</a>
</div>
<br />
<div id="content">
</div>
<script type="text/javascript" src="Javascript/submitDate.js"></script>
</body>
</html>
The aside element doesn't have an onload attribute (or load event). Only elements that load external content (e.g. <img>) and the document itself (where the attribute lives on the <body> element) do.
Use a <script> element instead.
<aside>
Last submitted:
</br>
<input type="date" id="dateShow" readonly>
</aside>
<script>
submitDate();
</script>
Additionally, you say that the file lives at "javascript/submitDate.js" but you are loading src="Javascript/submitDate.js". The function won't be available to call if you are using a case-sensitive file system (as the URL will 404).
You have a capitol 'j' in JavaScript in your HTML.
<script type="text/javascript" src="Javascript/submitDate.js"></script>
Try loading the js when the document is loaded
JS file:
document.onload = function(){
function submitDate(){
var time = new Date();
var nowDate =time.toISOString().slice(0,-14);
document.getElementById("dateShow").value=nowDate;
}
submitDate();
}();
The aside in your html
<aside>
Last submitted:
</br>
<input type="date" id="dateShow" readonly>
</aside>
Link to js file in the bottom of your body
<script type="text/javascript" src="pathtojsfile"></script>
Here is a working Fiddle

Countdown script not starting countdown

Can someone please tell me why the countdown function is not working properly (the countdown is not starting in the div with the I.D. "countdown"). Probably something real simple, but Javascript isn't my forte. This is the countdown plugin I am using: http://keith-wood.name/countdown.html
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Page Title</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link href="./css/web-style-second.css" rel="stylesheet" type="text/css">
<link rel="stylesheet" type="text/css" href="chrome://mozbar/skin/css/injected.css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.countdown.js"></script>
</head>
<body>
<a name="top"></a>
<div id="container">
<div id="content">
<div class="center">
<center>
<div></div>
</center>
</div>
<script type="text/javascript">
$(function() {
$('#countdown').countdown({
until: '14min+20sec',
format: 'MS',
layout: '{mnn}min ' + '{snn}sec ',
onExpiry: function() {
$(".hidden").css("display", "block");
}
});
});
</script>
<div class="time_box">
<h3 class="italic">When The Clock Hits Zero ... </h3>
<h4 class="hasCountdown" id="countdown">14min 20sec </h4>
</div>
<form name="signupFrm" id="signupFrm" action="#" method="post" class="hidden">
<div>
<div class="yellow_red">
<h1></h1>
</div>
<div class="center">
<a href="https://www.testing.com" class="btn_buy_now">
Get Started</a>
</div>
<input name="submit" value="submit" type="hidden">
<p class="mb_5"> </p>
</div>
</form>
<div class="fnote justify">
</div>
</div>
<div id="footer">
</div>
</div>
</body>
</html>
You should put the $(function () ...) script into the <head> tag of your HTML page. This way, the countdown will be initiated once the DOM has fully loaded.
I think that the problem is that you are missing the reference to the "jQuery Countdown CSS". In the usage instructions of the plugin it says:
Download and include the jQuery Countdown CSS and JavaScript in the
head section of your page. #import
"jquery.countdown.css";
But you can still make it work without the "jQuery Countdown CSS" if you remove the class attribute from the <h4> element with the id "countdown", like this:
<div class="time_box">
<h3 class="italic">When The Clock Hits Zero ... </h3>
<h4 id="countdown">14min 20sec </h4>
</div>
​JSFiddle Example
The countdown plugin uses the class hasCountdown to test whether the countdown has already been instantiated, so you should use a different class name.
From jquery.countdown.js:
/* Class name added to elements to indicate already configured with countdown.*/
markerClassName: 'hasCountdown'

</html>
So my problem is on the second page. I just added a new element and update the list view just to load the css jqm.
But if I use everything that is good pageInit except round the corners of the list view (data frame = "true"). He did not appear rounded, but I checked the css load, and should be all year. But when used document.ready everything is fine. Round the corners of the list view!
Please help me because I do not want to use document.ready.
$("#local").live('pagecreate', function (evt) {
var edit = $('#edit');
edit.append($('<li>test1</li>'))
});
Try replacing above code peace
