I have implement Cache tool on my cPanel server and configured it but i am getting Defer Parsing JavaScript warning in gtmetrix and google pagespeed
1) Put any js script reference to footer.
2)
a) Add Async attribute to the script.
<script async src="script.js"></script>
b) You can also test it with Defer attribute.
<script defer src="script.js"></script>
3) Optionally if possible try to combine the js files, this will give better result in PageSpeed in most cases.

quick cry for help: this website "broke" somehow and is stuck in the pre-loader
https://thelosertakesitall.com/ – I want to understand why and how to fix it, thank you!
I tried removing the elements displaying the loader but then it just stays at a blank screen. I understand the code is old and was set up by someone I do not have contact to anymore.
jQuery is not loaded because of:
Mixed Content: The page at 'https://thelosertakesitall.com/' was
loaded over HTTPS, but requested an insecure script
'http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js'.
This request has been blocked; the content must be served over HTTPS.
try to change
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <!-- Load jQuery library -->
to
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <!-- Load jQuery library -->
I've a problem with my website, the layout load properly (and CSS) but no JS and page in yield.
I've copy paste the layout of my other website, inclued tje JS and CSS file, I do not understand why it does not work while on other sites it's good..
Code for include the JS and CSS file: <script src="{{url('js/jquery.min.js')}}"></script>
As you can see, the page is empty, and this is not normal.
Image of error:
Ahh... ok.
I've forget to DL From:: into my project. Sorry
I had the same problem when I was creating a recent Laravel project however mine was narrowed down too 2 problems. 1 being the JS had an error and 2nd was the way I called it.
I fixed it by doing the following:
<script type="text/javascript" src="{!! asset('js/jquery.min.js') !!}"></script>
I would like to evaluate the features of pivot grid using simple test html without cmd.
I've read the information from those links but I still couldn't install a working environment
https://docs.sencha.com/extjs/6.0/co...ivot_grid.html
https://www.sencha.com/forum/showthr...out-Sencha-Cmd
http://se.sencha.com/setup-guide/
I've downloaded the core framework ('ext-6.0.1-trial.zip')
and pivot addon ('ext-addons-6.0.1-trial.zip') from sencha site
and unpacked them on my test web server:
www.mydummy.server.org/lib/extjs/ext-6.0.0/ <- framework
www.mydummy.server.org/lib/extjs/package/ <- addon
and tested it calling the pivots in kitchensink example with:
www.mydummy.server.org/lib/extjs/ext-6.0.0/examples/kitchensink/index.html
in such setup they start without errors.
The target location of the addon is a bit strange for me,
I was sure I should unpack addon to the package directory of the framework
www.mydummy.server.org/lib/extjs/ext-6.0.0/package/
but then the kitchensink example doesn't work
(kitchensink calls pivot with ../../../package/pivot )
Now I wonder how should I include framework and addon in own html example,
I've tried something like:
<link href="www.mydummy.server.org/lib/extjs/ext-6.0.0/build/classic/theme-neptune/resources/theme-neptune-all.css">
<script src="www.mydummy.server.org/lib/extjs/ext-6.0.0/build/ext-all.js"></script>
<link href="www.mydummy.server.org/lib/extjs/packages/pivot/build/neptune/resources/pivot-all.css">
<script src="www.mydummy.server.org/lib/extjs/packages/pivot/build/pivot.js"'></script>
<script src="www.mydummy.server.org/lib/extjs/packages/exporter/build/exporter.js"'></script>
The links are ok (no http error) but the simple pivot is not rendered
and framework couldn't load further classes:
[Ext.Loader] Some requested files failed to load.
What is the correct setup of extjs and pivot without cmd?
Thank you,
Annie
Couple things here.
For the KitchenSink, if you open up www.mydummy.server.org/lib/extjs/ext-6.0.0/ in your browser you will be shown an index.html. There will be a green button to show the examples which will point to www.mydummy.server.org/lib/extjs/ext-6.0.0/build/examples/index.html (notice the build dir in there). Then if you click on the KitchenSink it will load from www.mydummy.server.org/lib/extjs/ext-6.0.0/build/examples/kitchensink/ (once again, notice the build dir). This is due to the KitchenSink being a Cmd app which will build to that build dir. The examples dir outside the build dir is the development version of the app which is why we still provide it for the source.
Next, about how to use the pivot grid's Cmd package outside of the Cmd package. we build the Cmd package so if you look in the package's build dir you should see a built JavaScript and CSS file that you can load via <script> and <link> in your HTML.

Notice I have the exporter.js loading before pivot.js and this mostly works except that I do see something that I'd call a bug for us. In pivot.js, we define Ext.ux.ajax.PivotSimlet which extends Ext.ux.ajax.JsonSimlet (which is in the framework's ux package). This is fine to extend like this but PivotSimlet would only be needed if you want to have simulated data in your application (which most wouldn't unless in dev). Two ways you can fix this, remove that class from pivot.js or include the ux's JavaScript/CSS (however that package contains a lot of code that you may not need).
Thanks a lot for your explanation.
I've added these classes to get an working example:
<script src="http://releases/ext/6.0.1.250/packages/ux/src/ajax/Simlet.js"</script>
<script src="http://releases/ext/6.0.1.250/packages/ux/src/ajax/DataSimlet.js"</script>
<script src="http://releases/ext/6.0.1.250/packages/ux/src/ajax/JsonSimlet.js"</script>
I'm using the following code in a Laravel blade template to output a URL:
<script src="{{ URL::asset('js/jquery.js') }}"></script>
This outputs the URL like this:
<script src="http://example.com/js/jquery.js"></script>
I want it to output like this:
<script src="//example.com/js/jquery.js"></script>
I know that Laravel provides a way to output the protocol as https, but I'd prefer to use scheme-less URL's when linking to assets.
Is this possible?
URL::asset will only give http or https:
https://github.com/laravel/framework/blob/4.2/src/Illuminate/Routing/UrlGenerator.php#L146
https://github.com/laravel/framework/blob/4.2/src/Illuminate/Routing/UrlGenerator.php#L188
There are probably some better asset management solutions out there than Laravel's default solution. Laravel does a lot of things VERY well, but in some cases like this, in order to minimize bloat, it provides only basic functionality and expects the developer to use a better 3rd party Composer package for more advanced features.
I have a question about the <img> tag src attribute.
Is it possible to hide the <img> tag src attribute when viewing the source in a browser?
If it is possible, how? Please tel me if you have any reliable sources.
No, it's not possible.
You can set them dynamically with JS, but you can't hide them. You can store them as base64 encoded strings, and then decode them on the fly which will "hide" them from your page's source.
However, this is still utterly pointless as in the end, the browser still makes an HTTP request to fetch the image.
Simply spoken: This is impossible.
You might try to obfuscate your image src attributes (JS, Base64, etc), but for the browser to be able to show an image, you'll always end up exposing the image URI.
Which, in turn, means that everyone who knows their firebug will be able to see where your cute kitteh image comes from.
Alternative:
Generate One-Time URIs for your images (quite expensive).
Another good feature is to hide the location paths of your important scripts. I found a great npm plugin for this https://www.npmjs.com/package/location-hide
This works also for php href, src, content it will use everything inside src=""
You need only node.js for creating the exported files. It´s easy to use even if you don´t know node.js
It turns
<script src="test/folder/sample.js" type="text/javascript"></script>
<link href="test/stylesheet/perfect-scrollbar.css" rel="stylesheet">
into
<script src="TNANIuTOLZfmLYwaPDIYhcZDVOWKodqYhysaTeQHFPDhYlDLCOtxZqYmkKAhaSwSgbsYOWlpBzVSBtMZKSfwRqvPSqWVlBBuzHR" type="text/javascript"></script>
<link href="gyXeFnOEvZbgTjLvdZRnsyrfhaXqffkDjcdATTouqpIenCalLRXKamuXEtiKbPGCsNrdQIaqTMTNWsLyLFuxygKytaruWzSjKYMq" rel="stylesheet">
And it generate new jquery include codes like this to include your scripts with javascript in a external file
$('[src=\'TNANIuTOLZfmLYwaPDIYhcZDVOWKodqYhysaTeQHFPDhYlDLCOtxZqYmkKAhaSwSgbsYOWlpBzVSBtMZKSfwRqvPSqWVlBBuzHR\']').attr("src", "test/folder/sample.js")
$('[href=\'gyXeFnOEvZbgTjLvdZRnsyrfhaXqffkDjcdATTouqpIenCalLRXKamuXEtiKbPGCsNrdQIaqTMTNWsLyLFuxygKytaruWzSjKYMq\']').attr("src", "test/stylesheet/perfect-scrollbar.css")
Also I would suggest you that you include all of your external javascript codes in 1 single js file. This file you place in the root of your index file that you can make this
<script src="./allinone_external_file.js" type="text/javascript"></script>
Then make right htaccess that nobody can acces this file. You can also make a fake import script for the source code that every body can see. But this file is only a redirect for the real external js file. you make this multiple times as example + use other obfuscation tools. This will protect you from people searching exploits with your javascript codes. I know its no big deal and maybe you can see the jquery include codes if you know how. But anyway its a great protection.
