I have a AJAX/Javascript intensive webpage and is trying to create a static version of the site using <noscript> tags.
Problem: The elements within the <noscript> tags do not show up, but instead what's on the screen is what's left of the (non-functioning) interface for the original AJAX/JS site. It appears that the contents of <noscript> are being hidden under the original interface's divs.
How can I hide everything outside of the <noscript> section, and only show the contents of <noscript>?
HTML Structure
<body>
<div id="user_interface"></div>
<div id="javascript_portion"></div>
<noscript>
<p>Some static content</p>
</noscript>
</body>
Can be done in two steps:
1) set css for #user_interface and #javascript_portion to display:none
2) set display to block for same selectors somewhere in JS
You could add display:none using CSS to your javascript_portion div. And then remove it using Javascript. That way the Javascript part will only show if javascript is working.
How about writing the other content with Javascript, like:
<body>
<script type="text/javascript">
document.write('<div id="user_interface"></div>');
document.write('<div id="javascript_portion"></div>');
</script>
<noscript>
<p>Some static content</p>
</noscript>
</body>
The noscript tag is like an else section; as in if you have script, do xxx else do the stuff in the noscript tag.
Try something like this (I use jquery below):
<body>
<div id="withScriptBody" style="display:none">
... all stuff that requires java script here.
</div>
<noscript>
... all noscript stuff here
</noscript>
<script>
$(document).ready(function()
{
$("#withScriptBody").css("display", "block");
});
</script>
</body>

I'm trying to avoid adding online styling when JS is being disabled.
For example, I'd like to hide an element in the body when JS is disabled, but i'd like to do it from external CSS only.
I'd like to avoid adding style like below
<noscript>
<style>
...some style
</style>
<p class="no-js">You need Javascript enabled to view all of the content on this page.</p>
</noscript>
<body>
<div>element to hide when js disabled</div>
</body>
Is there an alternative to this?
Thanks!
" I'd like to hide an element in the body when JS is disabled "
You can create a class with display:none, assign it to all elements you want to hide if javascript is disabled, and through javascript remove this class from these elements, if javascript is disabled, then this class will always apply and all elements with this class are not displayed
JS Fiddle
var secrets = document.querySelectorAll('.secret');
for (var i in secrets) {
secrets[i].classList.remove('secret');
}
.secret {
display: none;
}
Try this code:
<noscript>
<style>
#foo {
display:none;
}
</style>
</noscript>
You should use <noscript> tag, for hide an element, in <style> tag make it display:none. there is no way to this with standalone css! but you can do this with javascript or etc, look other answer.
<noscript>
<style type="text/css">
.divtohide {display:none;}
</style>
<div class="divtohide">
Javascript is disabled!
</div>
</noscript>
Alternatively, just use Javascript to hide the div that tells users that they need js enabled (if Javascript is disabled, obviously it cannot hide the div, and it will be shown).
<script>
document.addEventListener("DOMContentLoaded", function() {
document.getElementById('nojs').style.display = "none";
});
</script>
I have seen some posts regarding wanting to do something like this, but I am at a loss to understand why my code doesn't work. I'm trying to make sure that users who visit a page have javascript enabled. If disabled, I want to hide all content and display a simple page with a message that the main page cannot be displayed without javascript.
I have the following:
<html>
<head><title>my site</title>
<noscript><style type="text/css">site {display:none;} </style></noscript>
</head>
<body onload="hideDiv()">
<div id="noscriptmsg">You need to have javascript enabled in order to view this site.</div>
<script type="text/javascript">document.getElementById("noscriptmsg").style.display = 'none';</script>
</body>
<body>
<div class="site">
<!--content -->
</div>
</body>
</html>
Currently this shows the correct javascript-enabled page, but a completely blank javascript-disabled page. What would cause this?
Why not use the build in noscript in one body tag:
<html>
<head><title>my site</title>
</head>
<body>
<noscript>
<style type="text/css">
#site {display:none;}
</style>
<div id="noscriptmsg">
You need to have javascript enabled in order to view this site.
</div>
</noscript>
<div id="site">
</div>
</body>
</html>
It looks like in the body onload you are trying to call the method hideDiv()
First, I'd recommend moving your script tag
<html>
<head><title>my site</title>
<noscript><style type="text/css">.site {display:none;} </style></noscript>
<script type="text/javascript">
// to the head tag
// and define the hideDiv() method
function hideDiv() {
document.getElementById("noscriptmsg").style.display = 'none';
}
</script>
</head>
<body onload="hideDiv()">
<div id="noscriptmsg">You need to have javascript enabled in order to view this site.</div>
<div class="site">
<!--content -->
</div>
</body>
</html>
and remove the extraneous body tags. You can use css to have the first div (the one with the notice) display at 100% width and 100% height. Also, someone pointed out you were missing the css class selector.
I have a script in an HTML page of the following:
<script id="scriptid" type="text/html">
<div id="insidedivid">
... html code ...
</div>
</script>
I am able to get the HTMLScriptElement using $("#scriptid") but I am not able to get the underlying div object with the id "insidedivid". Whats the way to do it?
It's not possible; the browser does not treat HTML content inside of <script> tags as part of the DOM. When you retrieve the content of the <script> tag with $('#idhere').html(), you're getting a string result.
To answer Troy's question, he's most likely including templates in the <head> of his document so he can ultimately render content dynamically on the browser-side. However, if that is the case, the OP should use a different MIME type than text/html. You should use an unknown MIME type such as text/templates--using text/html confuses what the purpose of the content is.
I'm guessing the reason you're trying to reach into the <script> tag and grab a div is because you've built smaller sub-templates within the single <script> tag. Those smaller templates should rather be placed into their own <script></script> tags rather than contained in one large <script></script> tag pair.
So, instead of:
<script type="text/template" id="big_template">
<div id="sub_template_1">
<span>hello world 1!</span>
</div>
<div id="sub_template_2">
<span>hello world 2!</span>
</div>
</script>
Do this:
<script type="text/template" id="template_1">
<span>hello world 1!</span>
</script>
<script type="text/template" id="template_2">
<span>hello world 2!</span>
</script>
I think it's perfectly valid to have a div inside a script tag (or at
least useful), if a div makes sense to the TYPE you defined for the
script. For example, John Resig uses a script tag with type "text/
html" in his micro-templating solution:
http://ejohn.org/blog/javascript-micro-templating/
In this instance though (and in reply to the original author) you add
an ID to the SCRIPT tag, and refer to that (I don't see why it
wouldn't work with that facebook type instead of html - but you'd
probably want to test it in a few different browsers ;). For the
example you gave, you can get a reference to the DIV by doing:
<script id="scriptid" type="text/html">
<div id="insidedivid">
... html code ...
</div>
</script>
$(function(){
alert($( $( '#scriptid' ).html() ).text() ); //alerts " ... html code ..."
});
The "trick" is to get the HTML of the script tag and turn in into DOM
elements with jQuery - but remember, because you are passing all the
HTML into the jQUery function then you are immediately selecting ALL
of the top level elements. In this case, there is just one DIV - so
you are just selecting that.
Your HTML is invalid. HTML Validator.
If you want to have HTML you can get just like that, use something like this:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8" />
<title></title>
<script type="text/javascript" src="//code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var msg1 = $('message1');
// Execute code here
});
</script>
</head>
<body>
<div id="content">Content</div>
<div id="hidden" style="display: none">
<div id="message1">Message 1</div>
<div id="message2">Message 2</div>
</div>
</body>
</html>
If you are making a templating system, you may want to use AJAX instead.
How can I give javascript for every div instead of the whole page?
<head>
my jquery
my javascript for the whole page
</head>
<body>
<div id="cc1">
Some content - I want to add Javascript for this div
</div>
</body>
I know we add javascript only in head of the page or we call functions write in external js in onclick of html button events.
I need separate JS for each div because I am going to have a <noscript> in every div to show some static ad content if user has disabled javascript ; else if user has already enabled javascript, I am going to generate a dynamic ad content with my own javascript.
So how you do it?
It sounds like you're wanting to do something like this:
<div>
<script type="text/javascript">
document.write("Content A");
</script>
<noscript>
Alternate content
</noscript>
</div>
<div>
<script type="text/javascript">
document.write("Content B");
</script>
<noscript>
Alternate content
</noscript>
</div>
This is an old-fashioned way of doing things and I don't recommend it. An alternative to using inline script/noscript tags is to put the "noscript" content in the divs, then replace the content with JavaScript after the page loads; that way, if JavaScript is disabled, the original content will remain.
If I get your question correctly, you cannot really add JavaScript for a div, you should add it for the whole page and then use it just in that div.
To make something happen inside that div, you have to work with <script> </script> tags and address that particular div. Otherwise just add another .js file on the head of the HTML file to make it do something on that div.
Hy
You can get a reference of that DIV, with var dvo = document.getElementById('id_div');
Then you can do and apply what you want to only that div.
<html>
<head>
<script type="text/javascript">
// jquery and javascript functions
</script>
</head>
<body>
<fancy-jquery-ajaxy-html-section>
</fancy-jquery-ajaxy-html-section>
<noscript>
sorry you came to the wrong place - this site is all jquery/ajaxy stuff.
</noscript>
</body>
</html>
I tried surrounding <fancy-jquery-ajaxy-html> with a <script type="text/javascript"></script> but then nothing from that section is displayed even for users with javascript enabled.
But what I want to do is hide that <fancy-jquery-ajax-html> section only if the user doesn't have javascript enabled.
It contains content that is useless to someone without javascript turned on, so it shouldn't be shown at all.
A user with javascript disabled should only see a message saying that the page can't be viewed without javascript.
Is there a way do that?
The easiest way is to hide the section with CSS (e.g. display:none), then show it through Javascript.
EDIT: just a little example
<div>Everyone sees this div</div>
<div id="mydiv" class="hidden">You see this div only with JS enabled</div>
<script type="text/javascript">
$("#mydiv").removeClass("hidden");
</script>
<noscript>
<div>You will see this div only with JS disabled</div>
</noscript>
And, of course, in your CSS:
.hidden
{
display: none;
}
You could hide your fancy section using css:
<div id="fancy_jquery_ajax" style="display: none;">
</div>
then you could use use JavaScript to display the element:
$("#fancy_jquery_ajax").css("display", "block");
I hope that's right, I actually don't use jQuery that much. :S
Another approach would be to generate that HTML using JavaScript, so it can't appear unless JavaScript is running.
What I did is to have my javascript hide the nojsdiv and show maindiv. This way, if you don't have javascript the message shows up.
<body onload="allowlogin()">
<div id="maindiv" style="visibility: hidden;">
...
</div>
<div id="nojsdiv">
The training system requires javascript to be enabled.
</div>
</body>
I prefer to add a class of .js to html tags as soon as jQuery has loaded. This allows my to write css rules that apply only when the user has javascript enabled/disabled. This keeps your show and hide code out of our JS and lets CSS do its job and style the page
Here's how I would approach your problem:
<html>
<head>
<style type="text/css">
.js #fancy_jquery_ajax {display: none;}
</style>
<script type="text/javascript" src="/scripts/jquery.js"></script>
<script type="text/javascript">
$('html').addClass('js');
$(document).ready(function() {
// Stuff to do as soon as the DOM is ready
});
</script>
</head>
<body>
<div id = "fancy_jquery_ajax"></div>
<noscript><!-- stuff to say if use had javascript disabled --></noscript>
</body>
</html>
It's important to note that we want to add the class of .js as soon as jQuery has loaded and not add it in our document.ready handler. Otherwise we'd be back to square one.
