While reading the User Guide for Embedding Bokeh content, specifically "Autoload Scripts" here: https://docs.bokeh.org/en/latest/docs/user_guide/embed.html#autoload-scripts
The suggestion is to use the bokeh.embed.autoload_static() function to generate a .js file and a <script> tag to embed it into an HTML document.
As the documentation states,
The script tag should be included in the HTML page wherever you wish to load the plot.
This works as intended. However, there is an additional note that makes no sense to me:
Note: The <script> tag loads a <div> in place, so it must be placed under <head>.
This seems contradictory to the previous instruction which asks you to place the <script> tag where we wish the plot to be loaded, and therefore somewhere under <body>. Placing this tag under <head> does nothing and does not load the plot at all.
Have I misunderstood this note? What is it actually trying to tell me?
It is a typo, it should indeed be <body>. I've created https://github.com/bokeh/bokeh/issues/10484

This question have been already treated on the internet but i dont find a simple answer.
I would like to load only thoses javascript files and css, before starting to run the body my website.
I'm using packery.js, but when my website appears at first, my divs are misplaced. When i reload the page, everything gets back in place.
Is there a way to say : does all css and js files have been donwload? Yes? Ok run the body.
Thank you
There isn't a lot of information you provided which would help us solve the issue directly, however couple of things...
Make sure all your scripts and styles links are places in the head tags. The HTML page gets rendered in browser Top-Down. I.E. It'll load any files from HEAD tags before the body is reached, same thing if you want your scripts to be loaded after the body is loaded.. just put them at the bottom, before the BODY closing tag.
Using JQuery would be the fastest solution if you wanted to perform some functionality after your page has loaded (I know there isn't a JQuery tag, however thought providing a JQuery answer could be advantageous.
$(document).ready(function()
{
//Document Loaded, Put code you want to execute here.
}
I'm using a low-code development platform called WaveMaker right now, and it gives you the option to customize the "markup" of the page (HTML, but you can't really edit <head>; the whole thing is kind of weird), the Javascript of the page, particularly with events like onpageload, etc., the style of the page (CSS), and the page's variables (JSON). I'm trying to embed Formstack forms, but every time the Markup section encounters a <script> tag, it deletes everything after the end of the tag. This is what the markup page looks like. I contacted support and they seemed to indicate that this was on purpose. Is there any way to make HTML run script included in-line without saying <script>? PS: I would be able to embed using iFrames, but for some reason the iFrames aren't working on the iPhone test program, even though they're working on the simulator.
What you can do is put it inside an HTML event attribute.
<body onload="/*your JS here*/">
</body>
If that does not work, try attaching onload to another HTML element or try one of the other event handlers (though I believe that they should have taken this into account as well)
How about this :
<body onload="javascript:(function(){
// you can place your code here it should run
alert('ok')
})()">
</body>
In Avatao's Senior Web Security Career Path, there is a hacking task, where you need to insert malicious javascript code - but the <script> is tag filtered (other tags aren't). Aenadon's answer gived me one solution:
<body onload="your JS here"> </body>
After submitting that, I checked the official solution, and I found that:
<img src="x" onerror=alert('xss')>
I am currently trying to implement the Google Tag Manager but I run into a problem since the GTM appends the tags right before the closing tag of the body.
Whenever I have a template that needs to call a bit of code from one of the scripts in the Google Tag Manager I get an undefined error. This is obvious since it does not matter where I place my script in my view, GTM will always come after it since it appends right before the closing body tag.
Is there any way to fix this behaviour and why does Google do it like this? I understand that it helps with non-blocking but they might as well just place async attributes on the scripts and it will almost do the same?
An example I have Facebook Pixel as one of my tags in GTM and I need to be able to make a specific event call when I am loading a certain page as my view.
fbq('track', 'Search');
Ofcourse this needs a fbq instance to begin with. This leave me with only one option and that is to try and place my script in my footer which is a general template and it will get messy.
Any workaround for this behaviour?
The issue you are facing is that the Facebook library is not completely loaded when you are calling your function.
One method would be to migrate your Facebook code to GTM trigger it on all pages
and fire your specific code on dom ready
You could also use the code from below and see when the _fbq.loaded variable is set to true.

You would have to create trigger based on this javascript variable.
Hope this helps
We implemented $.pjax in a CodeIgniter application a few months ago. And it seemed to be working perfect. Recently users started complaining that some buttons had strange behaviours sometimes. After debugging a while, we discovered that PJAX is moving script tags from the freshly loaded fragment to the head section of the document.
This is great, you would think, because title and css resources are also moved to the head. We can benefit from this (pushstate, browser tab name, ...).
Sadly, clicking another pjax link will not remove these added script/css tags. This can get strange when bindings to an element with the same id or class are present in the other newly added scripts.. It tends to break things.
Does anyone know how to remove earlier added script tags (not all, only those added by pjax)? Currently the only way out is to drop pjax.. But I love it to much :(
As the title of this question suggests, we think the easiest way might be to prevent $.pjax from moving the tags from the fragment to the head in the first place.
It has been a while since I asked this question. We found a workaround for this pjax behaviour.
pjax only moves 'linked' javascript and css sources. When the code is in the partial, it will stay at the same place and will be executed once the partial content is added to the DOM.
At Github some suggested to use context="inline" on the <script> tags that shouldn't be moved to the <head> section.
So our solution for scripts in partial views:
<script type="text/javascript" context="inline">
<?= file_get_contents(js_url().'controllers/'.$jsController.'.js'); ?>
</script>
Obviously one should check if the file exists before reading it with PHP.
This Github 'issue' pointed us in te right direction

I have no idea how to describe this accurately/intelligently because it seems to be completely impossible, yet there must some reason for it.
I am trying to leverage jquery, jquery-ui, qtip (tooltip for jquery) and highcharts (javascript charting), but for purpose of post I could just as easily been only using jQuery and jQuery-UI.
If I include my <script/> tags at the bottom of my <head/> element I get an error trying to call the .slider() extension to configure my sliders. But if I put the <script/> tags right before the closing of my <body/> element then everything works. To illustrate, the following will not work (obviously some pseudo code below):
<head>
<script jquery.js/>
<script jquery-ui.js/>
</head>
<body>
... html ...
<script type="text/javascript">
$(document).ready(function () {
$(".slider").slider( { .. options .. } );
} )
</script>
... more html *including* the .slider elements
</body>
However, if I move the two jQuery script tags to be right above the </body> closing element things work. When the script tags are in the head element and I debug my application, basically the page does appear to have completely loaded and Visual Studio highlights the line calling the .slider() function saying it doesn't know what slider() is. Looking at the call stack, it appears to be correctly calling it from the document ready function...the mark up all appears to be there as well, making me believe the document truly is ready.
Now I didn't include things that are required by asp.net 1.1/2.0 site in my pseudo code, namely a <form/> element with runat="server' and the use of a <asp:ScriptManager/> tag (we needed that for parsing monetary values from different cultures leveraging Microsoft Ajax). I can't believe they would be causing the problem, but maybe they are. Additionally, asp.net injects several of its own script sections (i.e. for validation, post back, etc.)
Regarding the form tag...all the html and document.ready markup would be inside the form tag, while the script tags are always outside of the form tag (either above it, in the head or below it at the bottom of the body).
Obviously I could leave the script tags at the bottom, and I very well may end up doing that, but I am trying to get a clean 'template site' of which to use when creating new client sites and it just feels wrong that I have a restriction forcing me to put those tags at the bottom of the html. I'm sure our framework code (or maybe asp.net's) is simply inserting something that is causing problems/conflicts with jQuery, but I don't really know how to go about debugging/diagnosing what that problem is. So if anyone has any suggestions I'd greatly appreciate it.
It looks like jQuery 1.3.2 is being loaded by ASP.NET (see your second WebResource.axd). The two library versions are overwriting each other. Thus the reason it works when you load 1.6.2 at the end of the page.
