Solution
My question was asked with little knowledge in HTML and JavaScript, I apologize for this. With more experience I can clearly see that this was not a good question asked, anyway the solution to my question was simply that the source file was not in the corresponding library.
The thing is, when I click on "live preview" in brackets IDE, I can see the dynamic diagram I have created, but when I double click on the index.html file, it is showing the navigation bar, but not the dynamic chart....So the difference is:
- Live priview: is showing the navigation-bar with the dynamic chart
- Double click on index.html: showing just the navigation-bar without the dynamic chart....?
Btw: I have also tested this in localhost with xamp, same problem there with no dynamic chart...
Here is my code: index.html:

I think the path of your dependancies are not correct, some time you ahve it relative, sometime not.
Try to put the absolutes one in relative? eg replace
<script type="text/javascript" src="/canvasjs/canvasjs.min.js"></script>
to
<script type="text/javascript" src="canvasjs/canvasjs.min.js"></script>

Questions I've already looked at:
Bootstrap JavaScript not working
twitter bootstrap drop down suddenly not working
Complete list of reasons why a css file might not be working
My Bootstrap styles seem to have suddenly stopped being applied, resulting in pages that look something like this. I'm using the layout generated by ASP.NET MVC 5, so there should be a navbar at the top, among other things. Ignore the red banner, the button doesn't show on that page anyway.
Nothing looks amiss in the dev tools -- console, network, etc. all look normal with no errors. All the files are loaded, and changing their order changes nothing. All of the .css and .js files are loaded from the local file system. I even reverted to a commit from yesterday, when the site was working fine, but the site still displays incorrectly.
I've tried turning it off and on again, now I'm out of ideas.
Edit: Same results, no matter the browser. I'm at a total loss here.

tl;dr OP updated from Bootstrap 3 -> 4 without updating HTML.
A week ago, I updated to Bootstrap v4(a?) via NuGet, without paying attention to the change in major version number. Apparently my cache didn't get cleared until a week later (when I asked this question), so I had forgotten the update even happened.
Bootstrap 4 is a major rework, so the bulk of my Bootstrap HTML became invalid.
Reverting Bootstrap fixes everything.

It's not an optimal solution but can you try replacing CiktiGetir function with this:
function CiktiGetir(e){
var htmlElement = document.querySelector("html");
var printContents = document.getElementById("Kolonlar");
// Make body invisible, append new element to HTML
document.body.style.display = "none";
htmlElement.appendChild(printContents);
window.print();
// Make body visible again, remove the added element
document.body.style.display = "initial";
htmlElement.removeChild(printContents);
}
Replacing HTML content breaks the JS events and dynamic contents.
You are replacing the body HTML
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
So you will need to reatach the events.
Try the "on" jquery method. Something like
$(document).on('click', '#CiktiGetir', function() { CiktiGetir(); });
My code was just an example. You will have to adapt it to your code.
You need to reatach the events after replace body content.
If, you dont want to to this, you can refresh the entire page.
function CiktiGetir(e){
var KolonlarinChildren=document.getElementsByClassName("divKolon");
var printContents = document.getElementById("Kolonlar");
printContents=printContents.innerHTML;
document.body.innerHTML = printContents;
window.print();
location.reload();
}
I am using the dropdown from bootstrap and i would like the button to have its text change depending on which of it's two dropdown items i click. The text changes according to the item clicked but the caret is gone after the first change and so forth. I want to keep the caret in the button!

<script>
function dropdown(val){
var y = document.getElementsByClassName('btn btn-default dropdown-toggle');

With your current code, appending the caret icon code will help you retain it after changing the drop down value.
function dropdown(val) {
var y = document.getElementsByClassName('btn btn-default dropdown-toggle');
var aNode = y[0].innerHTML = val + ' <span class="caret"></span>'; // Append

<li onclick="dropdown(this.innerHTML);">Fast</li>
<li onclick="dropdown(this.innerHTML);">Accurate</li>
</ul>
.innerHTML will get you the entire content, including the inner span that you are using for the caret.
What you need is the textContent of the firstchild of your dropdown, which is actually a textNode.
Example Snippet:
var dropdown = document.getElementsByClassName('dropdown-toggle')[0],
options = document.getElementsByClassName('dropdown-menu')[0]
;
options.addEventListener("click", function(e) {
if (e.target.tagName === 'A') {
dropdown.firstChild.textContent = e.target.textContent + ' ';
}
});

<div class="dropdown">
<button id="dropdownBtn" class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown">Fast <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li>Fast</li>
<li>Accurate</li>
</ul>
</div>
This is happening because you're replacing the html with the value - the caret span is inside the button (so part of the html of the button), so also getting replaced.
As you're using bootstrap, which uses jquery, use jquery to make this easy:
function dropdown(val) {
$(".btn.dropdown-toggle").text(val)
}
You can save the caret inside a variable and add it back when you change the value.
As you are using bootstrap, you already have jQuery loaded in the page so let's do it this way:
Fiddle
$myDropdown = $('#MyDropdown');
$myDropdown.find("li").click(function(){
$caret = ' <span class="caret"></span>';
$val = $(this).html();

Use innerText in the dropdown function instead of innerHTML
<li onclick="dropdown(this.innerText);">Fast</li>
Change the content of the function to replace the textContent of the firstChild which holds the value of the button.
var aNode = y[0].firstChild.textContent = val;
function dropdown(val) {
var y = document.getElementsByClassName('btn btn-default dropdown-toggle');
var aNode = y[0].firstChild.textContent = val;
}

This is the one and only permanent solution for bootstrap 3.This will work for all dropdown.

$(document).on('click','.dropdown-menu li',function(){

You can try:
$(".dropdown-menu li a").click(function(){
$(this).parents(".dropdown").find('.btn').html($(this).text() + ' <span class="caret"></span>');
$(this).parents(".dropdown").find('.btn').val($(this).data('value'));
});
I have built a directive for some of the boilerplate in the bootstrap navbar with ng-transclude for the navbar-collapse.I also find that there are two types of li elements for the navbar-nav items depending on whether the menu item is a dropdown or not.I find that this dropdown is however,not working.
I have built my code here in the plunker .
My JS code looks like this:
var app = angular.module('app',[]);
app.controller('main',['$scope',function($scope){
$scope.navbarOptions = {
color:'inverse',
position:'fixed-top',
collapseTarget:'navbar-ex1-collapse',
brand:'My Login',
};
$scope.menuItems=[{title:'home'},{title:'projects'},{title:'pricing'},
{
title:'Stack',
dropdown:['Java','Ruby','Javascript','Go']
}];
}]);
app.directive('bootstrapNavbar',function(){
return {
restrict:'AE',
templateUrl:'navbar.html',
scope:{
options:"="
},
transclude:true,
};
});
app.directive('bootstrapMenuitem',function(){
return {
restrict:'EA',
templateUrl:'bootstrap-menuItem.html',
scope:{
item:"#"
},
link:function(scope,element,attrs){
console.log(scope);
console.log(element);
console.log(attrs);
}
}
});
My html templates look like this:
//navbar.html
<nav class="navbar navbar-{{options.color}} navbar-{{options.position}}" role="navigation">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<!-- figure out a way to do toggle as an attribute directive -->
<button ng-show="options.collapseTarget" class="navbar-toggle" data-toggle="collapse" data-target=".{{options.collapseTarget}}">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">{{options.brand}}</a>
</div>
<div class="collapse navbar-collapse {{options.collapseTarget?options.collapseTarget:''}} navbar-body" ng-transclude>
</div><!-- /.navbar-collapse -->
</div>
</nav>
//bootstrap-menuItem.html
<li ng-hide="dropdown && dropdown.length">
{{item.title}}
</li>
<li ng-show="dropdown && dropdown.length" class="dropdown">
{{item.title}} <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li ng-repeat="action in item.dropdown">{{action}}</li>
</ul>
</li>

<ul class="nav navbar-nav">
<bootstrap-menuitem ng-repeat="item in menuItems" item="{{item}}"></bootstrap-menuItem>
</ul>
</nav>
</body>
</html>
The question is how do I access the item inside bootstrap-menuitem?
The template seems unable to use the item although it is in the scope?
UPDATE:
The item property accessed on the scope is a string,it needs to be an object.How can I obtain a property in the controller scope on the scope of a nested directive?
Using item:"=" instead of # causes the error http://pastebin.com/e9NDVH5b .
I assume that when using = on the bootstrap-menuitem it takes the item from ng-repeat?
However,it causes {{item.title}} to show up on the page.
In your index.html, remove double brackets in attribute item,
<bootstrap-menuitem ng-repeat="item in menuItems" item="item"></bootstrap-menuItem>
Besides, in your bootstrapMenuitem, change scope item's declaration from item: "#" to item: "=":
app.directive('bootstrapMenuitem',function(){
return {
restrict:'EA',
templateUrl:'bootstrap-menuItem.html',
scope:{
item:"="
},
link:function(scope,element,attrs){
console.log(scope);
console.log(element);
console.log(attrs);
}
}
});
This way, item can be passed to your directive's template as an object instead of plain text string.
I am trying to make a simplistic HTML editor for part of my website without things like Ace or TinyMCE. The problem is that when I'm using local storage, the save function appears to work, but the view function is not changing the notes to the saved notes.
I made a JSFiddle for all of you, at this URL.
Here is my HTML code:

Here is my JavaScript (it uses jQuery):
NProgress.start();
mixpanel.init("<CENSORED FOR SECURITY>");
mixpanel.track("Page Loads");
NProgress.done();
$(document).ready(function(){
if (Modernizr.localstorage) {
console.log("L.S.W.");
} else {
$(".errors").append("<div class="alert alert-danger alert-dismissible" role="alert"><button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×<\/span><span class="sr-only">Close<\/span><\/button><strong>Oh snap!<\/strong> Local Storage doesn't work on your browser. Saving won't work, so you might want to keep this open if you want to keep your notes.<\/div>");
NProgress.done();
};
$("#save").click(function() {
localStorage["note"] = JSON.stringify($(".editor").html());
});
$("#view").click(function() {
if (localStorage["note"] != null) {
var contentsOfOldDiv = JSON.parse(localStorage["note"]);
$(".editor").
$("div.fifth").replaceWith(contentsOfOldDiv);
} else {
$(".errors").append("<div class=alert alert-info alert-dismissible> role="alert"><button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×<\/span><span class="sr-only">Close<\/span><\/button><strong>Heads up!<\/strong> No save was detected. Did you save before?<\/div>");
};
});
});
So what am I doing wrong (I got the JSON parsing idea from another Stack Overflow subject!)?
You have several syntax issues. For example the lines below:
$(".errors").append("<div class="alert alert-danger alert-dismissible" role="alert"><button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×<\/span><span class="sr-only">Close<\/span><\/button><strong>Oh snap!<\/strong> Local Storage doesn't work on your browser. Saving won't work, so you might want to keep this open if you want to keep your notes.<\/div>");
and
$(".errors").append("<div class=alert alert-info alert-dismissible> role="alert"><button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×<\/span><span class="sr-only">Close<\/span><\/button><strong>Heads up!<\/strong> No save was detected. Did you save before?<\/div>");
You need to escape the " character or use a single quote. That might not solve your issue, but it's a start. Your code is failing when execution reaches that line, and it can't continue, which might explain why you aren't getting the expected result.
Try using your browser developer tools to find any errors in your code. This page has some information on finding and using the dev tools in your browser. The error in the JSFiddle is shown as:
Uncaught SyntaxError: Unexpected identifier
If you fix the quotation issues, you then get the error:
Uncaught ReferenceError: mixpanel is not defined
Keep going through the errors in your console and see if you can narrow down the issue that way.
