I have a group of CSS imports as like:
<link rel="stylesheet" href="/css/reset.css"/>
<link rel="stylesheet" href="/css/visualize.css"/>
<link rel="stylesheet" href="/css/datatables.css"/>
and some JavaScript code imports as like:
<script src="/js/excanvas.js"></script>
<script src="/js/jquery.js"></script>
<script src="/js/jquery.livesearch.js"></script>
<script src="/js/jquery.visualize.js"></script>
Is it possible to put all CSS import lines into a file i.e. cssImports.css and put all JS import lines into a file i.e. jsImports.js. So when I want to import that CSS and JS group files I will write something like:
<link rel="stylesheet" href="/css/cssImports.css"/>
<script src="/js/jsImports.js"></script>
so all the files listed above will be imported?
PS: I don't want to write any code belongs to web server specific.
Javascript imports: no.
CSS import: yes, but you shouldn't because it breaks parallel downloading of stylesheets.
Your best bet is to use a local build script (such as the Ant script included with the HTML5 Boilerplate) to concatenate your stylesheets and scripts before uploading them to the server, then linking to the 'master' resources in your HTML:
<link rel="stylesheet" href="/css/master.css">
<script src="/js/master.js"></script>
There is a tutorial on using the Ant script.
Go with LazyLoad! https://github.com/rgrove/lazyload/
It's a very small js (less than 1kb) that takes care of resource loading for you.
Download the package and save on your js folder. Then you would probably want to do this:
<script src="js/lazyload-min.js"></script>
Then for javascript files:
<script>
LazyLoad.js(["/js/excanvas.js", "/js/jquery.js", "/js/jquery.livesearch.js", "/js/jquery.visualize.js"], function () {
alert('all js files have been loaded');
});
</script>
Css:
<script>
LazyLoad.css(["/css/reset.css", "/css/visualize.css", "/css/datatables.css"], function () {
alert('all css files have been loaded');
});
</script>
This will also boost the performance of your page, enabling parallel css and js loading (the latter on firefox opera only).
You can Import CSS like this:
Create a new CSS cssImports.css and add there lines
#import url('/css/reset.css');
#import url('/css/visualize.css');
#import url('/css/datatables.css');
and relate it in your homepage as:
<link rel="stylesheet" href="/css/cssImports.css"/>
For Javascript import doesn't work. But you can create a single JS file and include the javascript code of each file after one another. But this is not recommended. It is better to have separate <script> tag for each js file.
for css:
<style>
#import url('/css/styles.css');
</style>
for js you could try something like
document.write("<script type='text/javascript' src='otherScript.js'></script>");
but i dont see a reason to do either of theese...
Yes just copy all the code and place in into a new file in the order than you would like it to run.
I know there are some javascript libraries that can do this for you but I dont have an experience of using them. I think Yahoo compiler/ YUI has one.
I'm not recommend do that because performance issue, but if you want the way, you can do that:
For CSS yes its possible, in cssImports.css you can put:
#import url(/css/reset.css);
#import url(/css/visualize.css);
#import url(/css/datatables.css);
But for JS, I think no way as much as CSS, but you can do this (adding JS files) from one JS file (ex jsImports.js), by write code create script element and add this element to page, like that :
var jsE = document.createElement('script');
var url = 'JS LINK HERE';
jsE.setAttribute('type', 'text/javascript');
jsE.setAttribute('src', url);
document.getElementsByTagName('head').item(0).appendChild(jsE);
Do this for each link of JS that you want to put, I have and idea, using Arracy contains JS links like this:
var jsLinks = new Array(
"/js/excanvas.js",
"/js/jquery.js",
"/js/jquery.livesearch.js",
"/js/jquery.visualize.js"
);
then a loop read a link each time and put this, like :
for (i = 0; i < jsLinks.length; i++)
{
var jsE = document.createElement('script');
var url = jsLinks[i];
jsE.setAttribute('type', 'text/javascript');
jsE.setAttribute('src', url);
document.getElementsByTagName('head').item(0).appendChild(jsE);
}
I didn't test my code, But I hope my idea is explained well.
Best
Edit 1: yes you can use Gatekeeper solution for JS (Very Simple), but it use "write" but "for me" I don't like that way :)
This is now possible as follows with HTML Imports which are in W3C draft
<link rel="import" href="import.html">
import.html
<link rel="stylesheet" href="/css/reset.css"/>
<link rel="stylesheet" href="/css/visualize.css"/>
<link rel="stylesheet" href="/css/datatables.css"/>
<script src="/js/excanvas.js"></script>
<script src="/js/jquery.js"></script>
<script src="/js/jquery.livesearch.js"></script>
<script src="/js/jquery.visualize.js"></script>
At this time only Chrome, Android and Opera support HTML Imports natively, but WebComponents provides a very mature polyfill script called webcomponents-lite.js to support all modern browsers

I am building a website and I'm trying to determine if there is a way to combine/consolidate specific files together without combining them into 1 giant file. I'm trying to clean up my pages I hate having to scroll thru my list for example
<!-- My plugins -->
<script src="./assets/js/plugins/moment.min.js"></script>
<script src="./assets/js/plugins/bootstrap-switch.js"></script>
<script src="./assets/js/plugins/bootstrap-tagsinput.js"></script>
<script src="./assets/js/plugins/bootstrap-selectpicker.js"></script>
<script src="./assets/js/plugins/jasny-bootstrap.min.js"></script>
<script src="./assets/js/plugins/nouislider.min.js"></script>
<script src="./assets/js/plugins/bootstrap-datetimepicker.js"></script>
<script src="./assets/js/photorevealer.js"></script>
<script src="./assets/js/type.js"></script>
I want to create a pointer or something similar to just to go something like
<link href="js_scripts.lst">
and that file is something like
<script src="./assets/js/plugins/moment.min.js"></script>
<script src="./assets/js/plugins/bootstrap-switch.js"></script>
export js_script
that way I can create 1 file for all the css, 1 file for js files, 1 file for google fonts and so on.
Make one file, links.js:
function loadjscssfile(filename){
var fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript")
fileref.setAttribute("src", filename)
if (typeof fileref!="undefined"){
document.getElementsByTagName("head")[0].appendChild(fileref)
}
}
Then call the function for all your files, again in the links.js file:
loadjscssfile("./assets/js/plugins/moment.min.js");
loadjscssfile("./assets/js/plugins/bootstrap-switch.js");
loadjscssfile("./assets/js/plugins/bootstrap-tagsinput.js");
loadjscssfile("./assets/js/plugins/bootstrap-selectorpicker.js");
loadjscssfile("./assets/js/plugins/jasny-bootstrap.min.js");
loadjscssfile("./assets/js/plugins/nouislider.min.js");
loadjscssfile("./assets/js/plugins/bootstrap-datetimepicker.js");
loadjscssfile("./assets/js/photorevealer.js");
loadjscssfile("./assets/js/type.js");
And then load the links.js file from your index.html page:
<script src="links.js"></script>
And then your files will load!
Note: You won't see these links while you're coding, but they'll be on the website if you hit Inspect. It's just tidier when you're coding.
I'm new to Laravel and whole framework stuff.
I do (may) understand a part of how the page rendered via laravel, but even after extensive search, I do not understand how laravel mix works.
Suppose that there is a page requires a global js and css library (lets specify jQuery and bootstrap)
Also the page requires custom js file like someJsTools.js.
Elementary speaking, in the past, those files referenced via <script src="blah"></script> and <link rel="blah" /> inside head tag and I used to it. In this env, all I have to do is specify those tags page by page.
// pageA requires jQuery.js, bootstrap.css and one CUSTOM JS file imatrouble.js
<head>
<link rel="stylesheet" herf="bootstrap.css"/>
<script src="jquery.js"></script>
<script src="imatrouble.js"></script>
</head>
//pageB requires jQuery.js, bootstrap.css and two custom js files.
<head>
<link rel="stylesheet" herf="bootstrap.css"/>
<script src="jquery.js"></script>
<script src="imatrouble.js"></script>
<script src="withimatroubleimadisasterlikewhateveryoucanimagine.js"></script>
</head>
PageA and PageB both requires common jQuery.js and bootstrap.css file. From what I learn, laravel Mix combine all js files into one and I don't get it here.
Problem 1 - One file do everything?
If it is true that "mix" things all together as one file, then how this one file could handle all of this different requirements seperatelly? I believe that my knowledge is wrong and its from my incorrect understanding of laravel mix and perhaps webpack mechanism.
Problem 2 - How can I manage all different page and every different situation?
Whether the problem above is originated from my missunderstanding or not, I cannot figure out what part of I (will) do could cause differences between pages. If mix only works for common global library, then all I have to do is just load custom js/css files manually. I currently assume that it is highly unlikely.
Please, someone help me to escape this chaos.
Have a good day.
It is purely based on your requirements. It depends on how you are customising your assets file.
For example :
Jquery, Angular,Bootstrap,Font Awesome is common for all your pages. So what I usually do is. I combine all css files to one file and all js files to one. Like below..
CSS mix
elixir(function(mix) {
mix.styles([
"libraries/bootstrap.css",
"libraries/font-awesome.min.css",
"custom/default.css",
], 'public/assets/css/common.css');
});
JS mix
elixir(function(mix) {
mix.scripts([
"libraries/jquery-1.10.2.js",
"libraries/bootstap.js"
"libraries/angular.js",
"libraries/angular-animate.js",
"custom/defaut.js"
], 'public/assets/js/common.js');
});
Suppose some pages need specific dependency[product, orders...etc]. For instance if product page needs wow.js, product.js and wow.css,product.css
CSS mix
elixir(function(mix) {
mix.styles([
"libraries/wow.css",
"custom/product.css",
], 'public/assets/css/product.css');
});
JS mix
elixir(function(mix) {
mix.scripts([
"libraries/wow.js",
"custom/product.js"
], 'public/assets/js/product.js');
});
So final laravel mix file looks like below
gulpfile.js
var elixir = require('laravel-elixir');
elixir.config.sourcemaps = true;
/**
* Global CSS MIX
*/
elixir(function(mix) {
mix.styles([
"libraries/bootstrap.css",
"libraries/font-awesome.min.css",
"custom/default.css",
], 'public/assets/css/common.css');
});
/**
* Global JS MIX
*/
elixir(function(mix) {
mix.scripts([
"libraries/jquery-1.10.2.js",
"libraries/bootstap.js"
"libraries/angular.js",
"libraries/angular-animate.js",
"custom/defaut.js"
], 'public/assets/js/common.js');
});
/**
* Product CSS MIX
*/
elixir(function(mix) {
mix.styles([
"libraries/wow.css",
"custom/product.css",
], 'public/assets/css/product.css');
});
/**
* Product JS MIX
*/
elixir(function(mix) {
mix.scripts([
"libraries/wow.js",
"custom/product.js"
], 'public/assets/js/product.js');
});
Now all your assets files are ready. Now you need to include wherever you want.
Suppose on your homepage you only requires common.js and common.css files.
homepage.blade.php
<head>
<link rel="stylesheet" href="{{ asset('assets/css/common.css') }}"/>
<script type="text/javascript" src="{{ asset('assets/css/common.js') }}"></script>
</head>
On the product page, you require both common and product assets file dependency. Include like below
product.blade.php
<head>
<link rel="stylesheet" href="{{ asset('assets/css/common.css') }}"/>
<link rel="stylesheet" href="{{ asset('assets/css/product.css') }}"/>
<script type="text/javascript" src="{{ asset('assets/js/common.js') }}"></script>
<script type="text/javascript" src="{{ asset('assets/js/product.js') }}"></script>
</head>
In my content editor you can change custom webfonts on the fly. If you change a font, it deletes all scripts and styles using the data-attribute as an identifier and the new ones then get appended after an ajax call. Now after some testing i realised it work's very well with css files but it ignores the < script >'s. Any ideas? Here is my Script:
$('head').find('[data-fontset-id=ce-fontset]').each(function() {
$(this).remove();
});
For example this is how the head section looks like:
<link data-fonset-id="ce-fontset" rel="stylesheet" href="..........">
<script data-fonset-id="ce-fontset" type="text/javascript" src="//use.typekit.net/xxxxx.js"></script>
<script data-fonset-id="ce-fontset" type="text/javascript">try{Typekit.load();}catch(e){}</script>
In this example, the css file gets removed but the javascript files didnt, any ideas why they are being ignored?
Thanks a lot in advance,
Michael
I am trying to use Jquery for the first time and I am getting an issue. I am using VS 2013, asp.net and VB.
My head tag is as follows.
<head runat="server">
<title></title>
<link href="StyleSheet.css" rel="stylesheet" type="text/css" />
<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
<script src="Bin/jquery-1.10.2.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('#LowerText').hide();
$('#UpperText').hide();
$('#AssetStatusChoice').change(function () {
if($('#AssetStatusChoice').val("Fully Available"))
{
$('#CommentsText').hide();
}
if ($('#AssetStatusChoice').val("Restricted"))
{
$('#UpperLimit').show();
$('#LowerLimit').show();
}
if ($('#AssetStatusChoice').val("Unavailable"))
{
$('#Commentstext').show();
}
});
});
</script>
</head>
When I debug the page I get the following error.
0x800a1391 - JavaScript runtime error: '$' is undefined
It seems from Googling the error that I am not referencing the js file correctly. Can anyone help?
Add <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script> and Remove the
<script src="Bin/jquery-1.10.2.js" type="text/javascript"></script>
<script> Just use a host Jquery instead of adding it to you source. Read more :
3 reasons why you should use hosted jQuery
IIS doesn't serve content in the /bin directory.
Move it to another directory like /scripts or /js or /scripts/lib, something like that. The bin directory is a bad place to put script files.
You have a number of options here. You could use the Google CDN by adding the following to your header:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
Or, as it appears you're using .NET, you could do this:
<script type="text/javascript" src="<%=ResolveClientUrl("~/Bin/jquery-1.10.2.js") %>"></script>
The second option gives you the additional advantage that when used in a master page can be used in any content pages at any file system level and it will still resolve correctly.
As Stefan has also said, I'd recommend moving your jQuery file from your bin directory.
Copy the jQuery file in some other folder, like Scripts, or js, and in Solution Explorer check to see all files. Find the jQuery file you just copied, include it in the project, then drag it on the page where you want to place it. A correct script tag will be created.
There is a website that references to a .js file and a .css file to format and add dynamic elements to its pages. The website gives the option to reference my own versions of those .js and .css files that I have hosted in a google code repository, and then will use those instead.
I'm trying to add another css file for mobile browsing. Currently I'm using #media arguments within the current css, but I'd like to have two separate css files.
Is there some code I could add to my .js file that would override the html, such that:
<html>
<head>
<link href="desktop.css" ...
Turns into:
<html>
<head>
<link href="mobile.css" ...
When the JS detects a mobile browswer. Keep in mind the js file is referenced further on in the HTML.
Thanks!
You can use media queries on #import rules:
<link href="master.css" …
#import url(desktop.css) (min-width:800px);
#import url(mobile.css) (max-width:700px);
Pls try this
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)) {
document.write('<link rel="stylesheet" type="text/css" href="mobile.css">');
}
else {
document.write('<link rel="stylesheet" type="text/css" href="desktop.css">');
}
And yes, it's a good practice to use CSS #media queries
Is there some code I could add to my .js file that would override the html?
Sure, you could override the html, but what's the point? It'll be too late, the browser will already have loaded and applied desktop.css.
If you want to maintain two separate css files, what you need to do is remove your static link tag, and apply the correct stylesheet dynamically based on browser detection:
var stylesheet=document.createElement("link");
stylesheet.type="text/css";
stylesheet.rel="stylesheet";
if (// detect mobile browser) {
stylesheet.href=mobile.css;
}
else {
stylesheet.href=desktop.css;
}
document.head.appendChild(stylesheet);
