Ok, stupid question and I don't think it's possible but, I have this markup at the top of my .aspx page...
<%--Third Party Libraries, Plugins, Extensions --%>
<script src="Libraries/Raphael/Raphael.js" type="text/javascript"></script>
<script src="AutoComplete/jquery.autocomplete.js" type="text/javascript"></script>
<script src="Libraries/jQuery/1.4.2/jquery.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.core.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.widget.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.mouse.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.draggable.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.droppable.js" type="text/javascript"></script>
Wouldn't it be nice if I could replace that with this...
<%--Third Party Libraries, Plugins, Extensions --%>
<script src="Libraries/Raphael/Raphael.js" type="text/javascript"></script>
<script src="AutoComplete/jquery.autocomplete.js" type="text/javascript"></script>
<script src="Libraries/jQuery/1.4.2/jquery.js" type="text/javascript"></script>
<script src="Libraries/jQuery/UI/1.8.4/jquery.ui.*.js" type="text/javascript"></script>
ie use the *
as wildcard.
Obviously as this is JS I could just throw all those scripts into one big script and load that but I don't really fancy doing that.
Anyone else have a technique for tidying up masses of script refs? Or do we just live with it?
The src attribute specifies the URL of an external script file. If you want to run the same JavaScript on several pages in a web site, you should create an external JavaScript file, instead of writing the same script over and over again.
You can use "wildcards" if your file names/directories follow a pattern, then you can make a loop to write them automatically instead of manually. ./ for files in the current directory, ../ for files one directory above and * for all matches e.g. <img src="../../content/images/IMG_*.
The type attribute in JavaScript is optional since the introduction of HTML5 brought some new improvements. JavaScript became the default language for HTML5 and modern browsers. So, now adding text/javascript isn't required in <script> tag.
As far as I know this is not possible, simply because, the browser would need to know exactly what files to request.
The browser would essentially have to brute force your server with requests hoping to get lucky.
I'd suggest using Google's closure compiler to merge all similar, if not all, javascript files into a single file. It will be slightly large, but would cut down on http request.
With some profiling you could find a balance between which files are needed most commonly and speed.
UPDATE (from comments)
I'm generally reluctant to offer adding a new javascript library to solve the issue of too many javascript libraries :) Plus this just seemed like the more straight forward solution. Current we use the Google closure API to compress and merge all our javascript and CSS and build time with ANT. Works a charm. This can also be done to some extent direct with apache2 virtual host/htaccess (see html5boilerplate.com) for examples and limitations
Nope, not in the way you're thinking of. You could do something that's similar if you're using JavaScript loaders (e.g. RequireJS or LabJS), since you can then condense each file into an array and loop through them, or, if you're feeling ambitious cook up some protocol between the front and back ends to support this.
Nonetheless, this is not recommended as it's not easy to maintain. If your problem with combining the files into a single one is with the effort, then JS minifiers (e.g. UglifyJS or Closure Compiler) may solve your problem.
