JavaScript not loading? - javascript

FIX: I linked to the wrong script, very sorry for this.
I have my script file linked correctly (at least I think so). Here's the link:
<script type="text/javascript" src="assets/js/menu.js"></script>
This link is right before the closing body tag. I have tried placing this link in the head section but that doesn't help.
Here is the JS code that's in that script file:
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
}

This script is for my push right menu on my website.
Any help, thanks! :D
UPDATE: I have added an alert into the script and that works but my menu still doesn't work?
Menu HTML:
<nav id="menu">
<ul>
<li>Contact</li>
<li>About Us</li>
<li>Blog</li>
<li>Home</li>
</ul>
</nav>

different browsers handle events differently. this is why you should use jQuery because it takes care of all the differences for you. This function should do it for you in plain JS..
function on(elem,eventType,handler){
if (elem.addEventListener){
elem.addEventListener (eventType,handler,false);
}else if (elem.attachEvent){
elem.attachEvent ('on'+eventType,handler);
}
}
on(window, "click", function(e){
// .. do stuff
});

Trying to add image changer in js

My goal is to have the image switch once it's been clicked and back again to the original image once the second image has been clicked again. I hope that makes sense. I've been trying this for two days with no success. Any help would be appreciated.
/* global document */
var cactusImage = document.querySelector('img');
cactusImage.onclick = function () {
var myImages = cactusImage.getAttribute('src');
if(myImages === 'images/cactus.jpg') {
cactusImage.setAttribute ('src','images/old-typewriter');
} else {
cactusImage.setAttribute ('src','images/cactus.jpg')
}

I have fixed your code. There is one error in your code i.e., you haven't mentioned the file extension whether its in .jpg or any other format in setAttribute. So let's say if your old-typewriter is in jpg format than this code will work if you have another format of image just replace jpg with that format and try to rerun this code.
var cactusImage = document.querySelector('img');
cactusImage.onclick = function () {
var myImages = cactusImage.getAttribute('src');
if(myImages === 'images/cactus.jpg') {
cactusImage.setAttribute ('src','images/old-typewriter.jpg');
} else {
cactusImage.setAttribute ('src','images/cactus.jpg')
}
}
I have edited complete code and you can replace your code with below code. It will work.

Holy-moly! So I took "Vipul's" suggestion of wrapping the code in script> and embedding the code in my HTML file which I wasn't doing before and voila. I want to thank all of you for the suggestions made. I hope I can return the favor one day.
Best,

function switchImg() {
if(imgSrc == "img1.png") {
document.getElementById("img").src = "img2.png";
imgSrc = document.getElementById("img").src;
}
}
Just replace the names of the image files.

How to get a bootstrap combo box?

I am trying to accomplish designing a filter/search feature that allows the user to easily search through a list for an item. I was told that I could accomplish this by using a Bootstrap combo box, however I have not seen any that have the ability to show the user values as soon as they start typing. The only ones I have found online where you had to click a button to see a drop down of the values.
This is the code I tried using, it works but instead I would like it to drop down the list only when I click the search input field. I am trying to make it without a button.
Code:
<!DOCTYPE html>
<html lang="en">
<head>

$("#myList li").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});
</script>
</body>
</html>
I tried adding this Javascritpt function, but it did not work.
Snippet:
function myFunction() {
document.getElementById("myList").classList.toggle("show");
}
You can hide automatically by triggering the toggle function in the page load. And to show the list you can use the toggle function again in focus event and to hide it again you can use it on the focus out event
<script>
$(document).ready(function(){
$("#myList").toggle();
$("#myInput").on("focus", function() {
$("#myList").toggle();
});
$("#myInput").on("focusout", function() {
$("#myList").toggle();
});
$("#myInput").on("keyup", function() {
var value = $(this).val().toLowerCase();
$("#myList li").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});
</script>

Refresh body tag if file input changes

I have a local non server webpage called DisplayItems.html which pulls a list from another webpage called items.html. I currently had it set up where DisplayItems refreshes its body every x seconds in case items.html got updated. I am trying to lean towards checking if the input has changed every few seconds. If so, refresh the body of DisplayItems, if not, don't refresh. How could I go along of doing this?
DisplayItems.html

Refresh();

Items.html
<li>new item1</li>
<li>senario2</li>
<li>senario3</li>
Maybe something like this? Using your html (get rid of the refresh in the body though, and use Jquery, obviously).
<script type="text/javascript">
function Checkforchange() {
$.get("/refresh/items.html", function (data) {
if ($('#text').html() !== data) {
$('#text').html(data);
window.setTimeout(Checkforchange, 5000);
}
});
}
$(document).ready(function () {
Checkforchange();
});
</script>

Creating tabs with listviews dynamically in jQuery mobile

I am trying to create tabs with listviews in JQM dynamically on a button click. Currently, I use JS array that contains sample data which will finally be populated via ajax. After research, it seems that I should trigger either trigger("create") or trigger ("refresh"), but apparently, I don't do it correctly. Here's the code:
HTML:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>navbar demo</title>

<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.4/jquery.mobile-1.4.4.min.js"></script>
<script type="text/javascript" src="../JS/nav.js"></script>
</head>
<body>
<button onclick="fillCategories()">Fill</button>
<div id = "decisions" > </div>
</body>
</html>
Javascript:
function fillCategories() {
var navElements = [{"category_sublist_id":"1","category_sublist_name":"Europe"},
{"category_sublist_id":"2","category_sublist_name":"Asia"},
{"category_sublist_id":"3","category_sublist_name":"Americas"}];
var categoriesTabs = $('<div id="categories">')
.attr("data-role","tabs")
.appendTo("#decisions");
var navBar = $("<div>").attr("id","categoriesNames")
.attr("data-role","navbar")
.appendTo("#categories");
var listElements = [{"sublist_row_id":"1","category_sublist_id":"1","sublist_name":"Great Britain"},
{"sublist_row_id":"2","category_sublist_id":"1","sublist_name":"Sweden"},
{"sublist_row_id":"3","category_sublist_id":"1","sublist_name":"France"},
{"sublist_row_id":"4","category_sublist_id":"1","sublist_name":"Germany"}];
$("#categoriesNames").append($("<ul>").attr("id","categoriesUl"));
$(navElements).each(function(){
$("#categoriesUl").append($("<li>")
.attr("value", this.category_sublist_id)
.append($("<a>")
.attr("href", "#sublist"+this.category_sublist_id)
.attr("data-theme","a")
.attr("data-ajax","false")
.text(this.category_sublist_name)));
});
$("#categories").append(navBar).trigger("create");
categorySublistView("categories", "sublist2", listElements);}
function categorySublistView(elementId, listLink, listData) {
var listId = listLink+"id";
var tab = $("<div>").attr("id",listLink)
.addClass("ui-content")
.appendTo("#"+elementId);
var list = $("<ul>").attr("data-role","listview")
.attr("data-inset","true")
.attr("data-icon","false")
.attr("id", listId)
.appendTo("#"+listLink);
$(listData).each(function(){
var li = $("<li/>")
.attr("value",this.sublist_row_id)
.appendTo("#"+listId);
var link =$("<a>")
.attr("href", "#")
.text(this.sublist_name)
.appendTo(li);
});
if ( $('#'+listId).hasClass('ui-listview')) {
$('#'+listId).listview('refresh');
}
else {
$('#'+listId).trigger('create');
}}
edit:
My initial intention was to draw 3 tabs in the navbar which are listviews, which are visible on tab clicks

jQuery Function for Split Lists

I'm trying to build some jQuery functionality into my site and I've caught a snag. I need to split a jQuery block style menu into 2 & possibly 3 columns vs having them all in one column on top of each other. I'll post as much as I can in here. I'm sure I'm missing something blatantly obvious. I'll start with the website I'm going off of:
http://upsidestudio.com/web/splitcol/2/
Now the CSS I've got:
.tabs {
width: 700px;
font-weight: ;
margin: 0;
padding: 0px;
float: left;
}
the <head> of my html: (I think my errors would be in here: I'm new to jQuery/Javascript)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script>
// execute your scripts when the DOM is ready. this is mostly a good habit
$(function() {
// initialize scrollable
$("#browsable").scrollable({circular: true}).navigator().autoscroll({

});
// initialize scrollable together with the autoscroll plugin
var root = $("#scroller").scrollable({circular: true}).autoscroll({ autoplay: false });
// perform JavaScript after the document is scriptable.
$(function() {
// setup ul.tabs to work as tabs for each div directly under div.panes
$("ul.tabs").tabs("div.panes > div")
});
});
<!-- !jQuery Split Navigation -->
$(document).ready(function() {
$('.tabs').each(function() {
if($(this).is("ol")) { var ordered = true; }
var colsize = Math.round($(this).find("li").size() / 2);
$(this).find("li").each(function(i) {
if (i>=colsize) {
$(this).addClass('right_col');
}
});
if(ordered) {
$(this).find('.right_col').insertAfter(this).wrapAll("<ol class='tabs' start='" + (colsize+1) + "'></ol>").removeClass("right_col");
} else {
$(this).find('.right_col').insertAfter(this).wrapAll("<ul class='tabs'></ul>").removeClass("right_col");
}
});
});
</script>
</head>
And Lastly...My Html section.
<!--THE TABS-->
<hr width="575" size="4" noshade align="left">
<ul class="tabs">
<li>What We Do</li>
<li>How It Works</li>
<li>FAQ</li>
<li>The Ajungo Team</li>
<li>Advertise</li>
</ul>
<hr width="575" size="4" noshade align="left"><br/><br/>
<!--TAB PANES COME IN BELOW THIS-->
Well, the biggest problem I can see there is that you've got a HTML comment stuck in the middle of the script block:
<!-- !jQuery Split Navigation -->
Remove that, then adding
.tabs {
margin-bottom: 20px;
}
And you can see that the ul.tabs list has been split in two. However, there a few inefficiencies in the script. It can be rewritten much, much more cleanly like this:
$('.tabs').each(function() {
var t = $(this), // Store a copy of both $(this) and t.children(),
children = t.children(), // to avoid calling the jQuery function too much
// Create a clone of the original list, then empty it and insert it after the original
secondList = t.clone(false).empty().insertAfter(this),
// Calculate the number of elements to move to the second list
// ie. half the number of elements in the list, divided by two and rounded up
length = Math.ceil(children.length / 2);
// Move half the children of the original list to the new one
children.slice(length).appendTo(secondList);
// If the list is an ordered list, let the list start at the correct position
if(this.nodeName === 'OL'){
secondList.attr('start', length + 1);
}
});
