My page takes about a second for the html to load. There are several hidden divs that are set to display:none initially and then accessed by jquery toggle during normal use. However, when the page is loading, those hidden divs flash for about half a second. If the page is hard-refreshed and it takes bouat 3-4 seconds to load, then those divs are displayed for about a second or two. I'm wondering if there's any way to prevent this. I'd rather not have them flash for second if kind of looks bad. A simplified html of the page is this.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Site - Home</title>
<link rel="stylesheet" type="text/css" href="style.css" />
<!--JQuery-->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type='text/javascript' src='javascript/popup.min.js'></script>
</head>
<body>
New Post
<!--Popup container-->
<div id="new-post-box" class="popup" style="width:500px;">
blah
</div>
<script type="text/javascript">/*popup function*/</script>
</body>
</html>
I don't know if that code is necessary, but can that div that display blah be prevented from appearing on the page load. Again it's set to display:none initially but I guess the css loads a little later than the html
Make sure the display:none property is in the css of the file and not in a document.ready() or other script. That should alleviate the issue.
In the case above (I'm guessing you want to hide class='popup') so make the following in CSS
.popup{
display:none;
}

I have 3 html files in my code. at this moment, I use a tag as a link and I want to add animation for the page switching.
I am using materialize but I can't find how to add animation for that.
Anyone can help?(I want when I click a button in my index.html, it will animate for example slide right, and change to menu.html)
This is the index.html code:
<!DOCTYPE html>
<html lang="en">
<head>
<link rel = "stylesheet" type="text/css" href = "Sources/bootstrap.css">
<link rel = "stylesheet" type="text/css" href = "Sources/Matirialize.css">
<script type = "text/javascript"
src = "Sources/jquery-2.1.1.js"></script>
<script src = "Sources/Matirialize.js"></script>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src = "jquery.js"></script>
</head>
<body>
<a class="waves-effect waves-light btn">button</a>
</body>
</html>
and this is the menu.html code:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<p>this is supose to be the menu page</p>
</body>
</html>
Under normal circumstances, you cannot create animations for transitions between two separate HTML pages, since the browser "gets rid" of the first page and stops all of its code before it begins to load the second page (and therefore, before its code begins to run). Basically, during the time between pages, you don't have the ability to run your own code to create animations.
If you look at the link לבני מלכה posted in the comments, however, you can see some ideas for getting around this by making the browser load the new page in special ways and then inserting it into the browser window (rather than just having an a link).
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
}
Description:
I have a main page with header, footer, etc. The content (a div within body) of this page is changing depending on where you click(menu items). The content loaded are different pages within javascript and css files.
Problem: javascript and css files of the pages loaded don't work. I have to include ALL the page in order to make it works.
For example in the next code, javascript included in status.jsp don't work:
$(document).ready(initialize);
function initialize(){
// status.jsp has javascript and css linked
$("#content").load("pages/status.jsp #information");
}
However, this works, but it is not what i want:
$(document).ready(initialize);
function initialize(){
// status.jsp has javascript and css linked
$("#content").load("pages/status.jsp");
}
The result of the last code is a page similar to this:
<html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="js/jquery-1.11.1.js"></script>
<title>MainPage</title>
</head>
<body>
<div id="content>
<meta charset="utf-8">
<link rel="stylesheet" href="styles/styles.css" type="text/css">
<title>Status</title>
<div id=statusBox">
information
</div>
<script type="text/javascript" src="js/status.js"></script>
</div>
<script type="text/javascript" src="js/main.js"></script>
</body>
</html>
I'm quite new in html5 & js and i have some troubles to develop a jQuery Mobile exemple.
From this, i'm just calling another header (partial) when a product is selected to render.
_header2.php:
<!DOCTYPE html>
<head>
<title>h2: <?php echo $_GET['product']; ?> </title>
<meta charset="UTF-8" />
<meta content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0;' name='viewport' />
<link rel='stylesheet' href='assets/css/styles_mob.css'/>
<link rel='stylesheet' href='assets/css/styles.css' />
<link href='assets/css/jquery-mobile.css?<?php echo filemtime("assets/css/jquery-mobile.css");?>' type='text/css' rel='stylesheet' />
<script type='text/javascript' src='http://code.jquery.com/jquery-1.7.min.js'></script>
<script type='text/javascript' src='http://code.jquery.com/mobile/1.0rc2/jquery.mobile-1.0rc2.min.js'></script>
</script>
<script type='text/javascript'>
function mymessage(msg)
{
if(!msg) msg="?";
alert(msg);
}
</script>
</head>
<body onload="mymessage('onload !')">
<div data-role="page" id="Home">
<div data-role="header" data-theme="b">
Home
<h1> <?php echo $title?></h1>
</div>
<div data-role="content">
Header code appair correctly on the generated page but js call of mymessage() in body tag doesn't work. Same problem when i try to call it from another partial code (_product.php) :
<li><a href='#Gallery1' onClick='mymessage(\"press gallery\")' >...</li>
...concole return: referenceError: mymessage is not defined
Everything rock only when a refreshing the current page !!
I've rode some posts (1, 2, 3) with similar problem but i'm still lost.
Any idea please ?
You're missing the <html> tag. You also have an extra </script> closing tag. This could potentially lead to your error.
There are all sorts of strange coding styles and errors like missing the <html> tag, an extra </script> closing tag, missing the closing tag on your anchor in <li><a href='#Gallery1' onClick='mymessage(\"press gallery\")' >...</li>, and list items should be inside <ul></ul>.
Try this code, it should work. Then analyze it and learn!

<div data-role="content">
<ul> <!-- Here is your link, working -->
<li>...</li>
</ul>
<!-- added some closing tags for demo-sake -->
</div></div>
</body></html>
PS: since all the beginner errors and the fact that this is just part of your code, I strongly assume the rest of your code has such strange error's to.
Good Luck!!
UPDATE:
Depending on what you'd like to accomplish on page-load, jQuery Mobile might completely change the ballpark.
As can be read in jQuery Mobile's documentation:
By default all navigation within jQuery Mobile is based on changes and
updates to location.hash. Whenever possible, page changes will use a
smooth transition between the current "page" and the next, whether it
is either already present in the DOM, or is automatically loaded via
Ajax.
Another quote from the documentation:
Use $(document).bind('pageinit'), not $(document).ready()
The first thing you learn in jQuery is to call code inside the
$(document).ready() function so everything will execute as soon as the
DOM is loaded. However, in jQuery Mobile, Ajax is used to load the
contents of each page into the DOM as you navigate, and the DOM ready
handler only executes for the first page. To execute code whenever a
new page is loaded and created, you can bind to the pageinit event.
This means that the regular techniques described will only fire when you first visit the page, not while navigating the page ajax-style.
Thus in jQuery mobile you must use pageinit or pageshow or one of the other events that are explained in the documentation that suit your exact purpose.
Example how to get pageinit fire for every page (tested live on your site):
$(document).on('pageinit','[data-role=page]', function(){
mymessage('hihi');
});
Or alternatively you could turn off ajax in jQuery Mobile, like this (depends on version):
$(document).bind("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
Here is my simplified code which has two pages which link to each other. The result is the page2 count alert always says there is one #page2 div in the DOM. However pagecreate fires for each time that page2.html has been referenced. First time is 1, second time is 2, and so on...
Can someone explain what is going on and how to get one pagecreate event for page2?
index.html

<link rel="stylesheet" href="jquery.mobile-1.0.1.min.css" />
<script src="jquery-1.6.4.min.js"></script>
<script src="jquery.mobile-1.0.1.min.js"></script>

<div data-role="page">
<div data-role="content">

Go To Page2
</div>
</div>

page2.html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id="page2" data-role="page">
<div data-role="content">
Back
</div>
<script type="text/javascript">
alert("page2 count is " + $("#page2").length);
$("#page2").live('pagecreate',function(event, ui) {
alert("in page2 on pagecreate");
});
</script>
</div>
</body>
</html>

jQM loads subsequent pages into the same DOM (page) using a debugger/dev tools with Chrome you can easily see this happen.
In subsequent pages it pulls in anything between your tags, but ignores everything else, you could have JS in your or other pages and it'd still only pull in page2.
What exactly is happening with you is that when you load #page2 the first time it properly adds a live event to #page2, then you navigate to index.html, but #page2 remains in your DOM. Now when you goto #page2 again, it will run your JS again
$("#page2").live('pagecreate',function(event, ui) {
alert("in page2 on pagecreate");
});
This binds your alert again, and 2 events fire, next time 3 will fire.
The way you're supposed to do it is load all your JS at the start and listen for the pageinit/pageshow, see my other post: https://stackoverflow.com/a/9085014/737023
Or if you have any questions ask here
