Bootstrap popover only works on hover - javascript

I have been having a hard time getting Bootstraps popover's to show on click and not on hover. I looked at the example on this page.
http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_popover&stacked=h
I have copied over the exact script src links from the example as well as the meta and link lines. I also initialize the popover to no avail. Here is a simplified version of what I'm working with.
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" type ="text/css" href="style.css" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta charset="utf-8">
</head>
<body>
<div id="container">
Toggle popover
</div>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('[data-toggle="popover"]').popover();
});
</script>
</body>
I don't know if this is a normal thing to do or not but i tried opening up the page, right clicking the a element and clicking inspect(in chrome.) In the bottom right it shows me two errors.
Uncaught Error: Bootstrap's JavaScript requires jQuery
Uncaught TypeError: $(...).popover is not a function
It cant find JQuery? Its certainly there. The element shows and the text reads when I hover over it and nothing happens when I click it.

Include the jQuery script first:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
This error is logged to the console on page load:
Uncaught Error: Bootstrap's JavaScript requires jQuery
Meaning the bootstrap js is looking for the jquery object.

Make DIV load CSS file

For the program I'm writing I have a main navigation page where the user get landed after he / she log into the system.
On this screen I use 2 DIV's one div is for the navigation bar second one is used as an iFrame.
I'm using w3.css library to create the navigation bar but this actually mess up my CSS main CSS file when I load the target file in the second div. But it works fine if I use an iFrame which I really don't like to do.
If I could load my CSS file when the div loads the target link file the problem will be solved.
So my problem is how to load the CSS file in to the div when the external file loads.
This is my HTML:
<html>
<head>
<title>Time Sheet</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Style Sheets -->
<link rel="stylesheet" type="text/css" href="../../CSS/w3.css">
<link rel="stylesheet" type="text/css" href="../../CSS/main.css">
<!-- Java Scripts -->
<script language="JavaScript" type="text/javascript" src="../../jScripts/jquery-3.2.0.min.js"></script>
<script language="javascript" type="text/javascript" src="../../jScripts/navBar.js"></script>
<script language="JavaScript" type="text/javascript" src="../../jScripts/fileLoader.js"></script>
</head>
<body>
<div class="w3-bar w3-light-gray w3-card-4" style="z-index: 991">
Home
Link 1
Link 2
Link 3
</div>
<div id="My-container">
<!-- All pages load here -->
</div>
</body>
</html>
My NavBar JavaScript:
$(document).ready(function(){
$('#main').click(function () {
$('#My-container').load('listUser.php');
})
});
File loader JavaScript:
$(document).ready(function(){
if($("#my-container").size>0){
if (document.createStyleSheet){
document.createStyleSheet('../../CSS/main.css');
}
else {
$("head").append($("<link rel='stylesheet' href='../../CSS/main.css' type='text/css' media='screen' />"));
}
}
});
Above file loader function is not mine I found it on a site and tried to use it but when I do console throws an error saying "Size" is not a function. When I change it to length the error goes away but code doesn't work.
If any one asks why don't you just copy paste the nav bar to all the files my answer is I'm lazy.
Any way please show me the light.
It seems you want to check if that specific dom exist or not. For that you need to use length. Also the dom id seems to be My-container but not my-container.
You can try the following
if($("#My-container").length>0){
// rest of the code
}

bootstrap javascript requires jquery error

This is my .cshtml code
<!DOCTYPE Html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>welcome</title>
<link href="~/Content/bootstrap.css" rel="stylesheet" />
<script src="~/Scripts/jquery-1.8.0.min.js"></script>
<script src="~/Scripts/bootstrap.js"></script>
</head>
<body>...</body>
</html>
Whenever I execute my code it gives the bootstrap requires jquery error. Please suggest what should I do to remove this error.
Make sure that the path is correct and points to jQuery version greater than 1.9
You are using 1.8 which is not compatible with bootstrap
Source:
https://github.com/twbs/bootstrap/blob/v3.1.1/bower.json
Just as Amit Joki said, make sure you link points directly to the jquery file and
the file name is spelt accordingly.
Also ensure that you link jquery js script before you link to the bootstrap js script
<script src="path_to_script/jquery-1.8.0.min.js"></script>
<script src="path_to_script/bootstrap.js"></script>
<link href="path_to_script/bootstrap.css" rel="stylesheet" />

window.onbeforeunload not working in second page

Hi I have two html pages in my mobile application as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>jQuery Mobile: Demos and Documentation</title>

<body>
<div data-role="page" id="jqm-home" class="type-home">
<div data-role="content">
Index
</div>
</div>
</body>
</html>
my example.html is like:
<!DOCTYPE html>

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

</head>
<body>
<div data-role="page" id="jqm-home" class="type-home">
<div data-role="content">
Test
</div>
<script type="text/javascript">
window.onbeforeunload = function(evt) {
console.log ("*****************");
}
</script>
</div>
</body>
</html>
Now suppose on click of Index button I goes to example.html page. on click of back button in example.html it again goes to index.html. everything is fine, but it does not print console.log ("********"); If i press one more back on index.html then it prints it, what I want is it should print that on click of back button when I am on example.html.
Whats wrong in above code? and why it behave like this? Any suggestion will be appreciated thanks in advance.
In Jquery Mobile standard use you basically stay on the same page during your hole experience on the site. "Changing" page basically adds content dynamically to the current document, meaning it will not trigger your onbeforeunload event.
You can however use jquery mobile events, which one depends on exactly what kind of action you want to take. Most probably you would be looking at pagebeforehide or pagehide
What you can do is add an event to the back button.
If you have a button :
<button id="backButton"> Go Back </button>
you can add via jquery following event
$("#backButton).click(function(){
console.log ("*****************");
});
Keep in mind, if you click a button, a post will happen and the page will be refreshed. So you should add the log function inthe document ready of the other page.
So if the example.html page loads, you just fire this event
$(function(){
//All code that starts when the page is fully loaded.
console.log ("*****************");
});

jquery mobile loading image not shown

My code:
<!DOCTYPE html>
<html>
<head>
<title>a</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="jquery.mobile-1.2.0-alpha.1.min.css" />
<script src="jquery-1.8.0.min.js"></script>
<script src="jquery.mobile-1.2.0-alpha.1.min.js"></script>
</head>
</html>
<script>
$(document).ready(function(){
$.mobile.loading('show');});
</script>
But the beautiful spinner image is not showing.It just shows a grey circle in the middle of the screen.
I think your syntax is off, to display a loading message you should use $.mobile.showPageLoadingMsg Also make sure you have the images folder included.
Edit:
Sorry I see that you are using the alpha of JQM 1.2, it looks like the $.mobile.loading method was added in this release. At any rate make sure that you have the JQM images folder and that it is located in the same folder as the js file. To test try replacing your links with links to the CDN
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0-alpha.1/jquery.mobile-1.2.0-alpha.1.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>

jQuery + jQuery mobile load script twice when script tag is emebedded in body

i have found a strange behavior when i was learning jQuery Mobile. below is my test code. the firebug shows the "test.js" was loaded twice if i put the script tag in body(even the "test.js" is empty). is this a bug or we could not put script tag in body when we are using jquery mobile?
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta charset="utf-8">
<title>test</title>
<link href="http://code.jquery.com/mobile/latest/jquery.mobile.min.css" rel="stylesheet" type="text/css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/latest/jquery.mobile.min.js"></script>
</head>
<body>
<script type="text/javascript" src="/test.js"></script>
</body>
</html>
I had the same problem, put all your javascript in the head. This solved the issue for me.
I've never ran into such issues, but try adding the script tag AFTER the element (but before the ) one), or even better, load it dymically after the pagecreate event.
