Files In A Production Environment?
Jan 21, 2011
I am moving from a development environment to a production environment and would like to know the best way to handle javascript/jquery files on the production server. I have looked at Packer and also searched this forum for ideas but the only threads I came up with were a year old and I would prefer some comments more recent than that I think.
Obviously I would at the very least like to strip out comments, etc. and would also like to minimize them as much as possible if that makes a performance difference. Any input is welcome at this point.

Just wondering if anyone has any ideas on how to solve a particular
problem. A client wants to print barcode labels from their (web/php
based application). The barcode labels are very small, so I'm guessing
that doing a screendump via a standard inkjet isn't going to work
(i.e. might need somehow to print to a barcode printer!)
Any ideas where to start?

i accidentally set up my path variable instead of classpath and now my
computer can't find any of the executable files. it would be great if
anyone knew what really should stand by the path variable. i don't
suppose there's something like 'set all to default?

I am extremely frustrated with my current setup developing jquery as I am in Dreamweaver. I've installed the add ons but they dont help enough. My biggest beef is with something that auto-indents to make the structure of the code legible. That and decent colouring. Can anyone recommend something that does all that and potentially even reloads the page on save....and previews in browser...and debugs?

I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.The script works fine when the requested XML file is stored on the same server as the script.The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
Code:
window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;
[code]....

I have a page that's built using ASP.NET and using a master page.Page contents shows up for a moment then I get a blank page - when I run it. If I remove the jQuery code from my page - then I get the contents.
I tried putting the following in the master page.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" >
</script>

I have some Flash SWF games on my website with advertising banners on them.
People access a certain game by going to
http://www.mysite.com/flashgame.htm. With IE no problem. But in Firefox they
can type in http://www.mysite.com/flashgame.swf and bypass my banners. The
banners help pay for me hosting these games.
Is there a way with javascript that I can tell when they are going directly
to the swf file instead of going to the htm page? And redirect them to the
htm file?

In lets say I have an HTML document that has this in it:
<script type="text/javascript" src="file1.js"></script>
<script type="text/javascript" src="file2.js"></script>
I am trying to use a function that is defined in file 1 inside file 2. Its not working because its telling me that the function is undefined. Is there any way to make one file "see" the functions inside the other file in javascript?

I have a form, which has a user and password, that a user enters
when i want to submit this form....
i would like to submit it to 2 two different files.
so file1.asp would have user and password....and file2.asp would have
user and password.
i would like two different windows to open, if possible. so the user
can work on both windows at once.
window 1 = file1.asp
window 2 = file2.asp

I'm writing a class that will enable the user to upload files to
the server without reloading the current page (using target="iframe"),
and it works just fine in Firefox, but when I test it in IE, first of
all, the iframe is not targetted at all, and IE stupidly opens a new
window, second the <input type="file" element looses it's name
attribute for some reason... I tried using DOM and assigning the
element thru innerHTML, both will just not work in IE (and will just
fine in Firefox). Those interested to have the source code (commented
in french) may just ask me. But if anyone had similar problems, and
would want to share with me, I'd really much appreciate, because this
is driving me insane!

This seems like a really stupid question. Can you include a javascript
file in a javascript file?
Rather than doing this:
<script src="A"></script>
<script src="B"></script>
I want to do
<script src="A"></script>
and then have in script A:
include("B");
where include is a magic word that includes the file B.

Is it possible to have JavaScript do a checksum of a file a user has
chosen to upload via a multipart html form? I'd like have JavaScript
do a checksum on the client side, embedded the result in the form, and
then have a CGI on the server check to ensure the server-side checksum
matches the client. Is such a thing even possible?

I have recently bought the book: JavaScript & DHTML Cookbook. As I
opened the .js files with note pad, I asked myself why was the code
formated in such a way. The code looks as if it had been produced by
some kind of programs instead of a person. I also noticed a lot of
little squared zeros; what are those all about?
I have also noticed code formated in a similar way, when viewing some
of the source code of the web pages on the MSN web site. If someone
knows anything about this machine-like formating, I would love to hear
from you.

my website [URL] has been left unfinished by my friend and it doesnt look like he can finish it now. I have some understanding of code and have manually edited the existing pages in notepad to fix some issues. The one issue I have left is on the javascript samples player which overlays the main screen. I have all of the files (an flv and swf plus a folder full of js and a vbs file). As you will see, the morning chapter does not play but all of the others do. I have checked the flv in a player and it works fine, and it was created in the same way as the others. All flv and swf files are uploaded correctly I just can't work out why it is not working.

This function will produce a URL that appears to be a file.
There are two versions:
1. a 500-pound gorilla version that accepts almost anything as input.
2. a lightweight version that turns strings into virtual HTML files.
First I'll mention the one major drawback: IE doesn't recognize data urls (http://en.wikipedia.org/wiki/Data:_URI_scheme) yet.
For a Live Demo, paste this into your addressbar and click go. (press back to return).
data:text/html;charset=utf-8;base64,PGI+aGVsbG8gd29ybGQ8L2I+
//output of: dataUrl("<b>hello world</b>", "text/html")
With that out of the way, here's the code:
function dataUrl(data, mimeType){ // turns a string into a url that appears as a file. (to ff/op/saf)
encType= (!!btoa) ? ";base64" : "";
var esc = (!!encType) ? function(d){return btoa(d);} : function(d){return escape(d);};
if(!mimeType){mimeType= (data.nodeName) ? "text/html" :"text/plain";};
b="data:"+mimeType+";charset="+document.characterSet+"+encType+",";
if ("string number date boolean function".indexOf(typeof data) > -1){ b+=esc(data.toString()); return b; };
if ( data.constructor==Array){b+= esc( data.join("") );return b; };
if(typeof data=="xml"){b+=esc(data.toSource()); return b;} //FF2 xml frag/doc
//for more complicated data, attempt to determine the format.
if(typeof data=="object"){
if(!!data.value && !!data.value.length){b+=esc(data.value); return b;}; //input tags w/content
if(!!data.innerHTML){b+=esc(data.innerHTML); return b;} //HTML tag
if(!!data.length){ //weird stuff like nodelists
var G=function(ob){r=[]; i=0;
for(i;i<ob.length;i++){
if(dataUrl(ob)) r=dataUrl(ob[i]);} return r.join("
");};//end g
return(b+G(data));}//end if object w/length
if(!! eval(data.toSource()) ){b+=esc(data.toSource()); return b;}; //JSON
}//end if object
return;
} //end function dataUrl
function dataUrlStr(data){ return ("data:text/html,"+escape(data));}
Usage: dataUrl(data, mimeType)
data- The desired contents of the file
mimeType- The type of content you want the browser to see.
output: An encoded string representation of the file; an href.
The output 'file' could be any text-based file format, depending upon what you set mimeType to be:
-HTML document (yawn) (text/html)
-Rss feed (text/xml)
-M3U playlist (audio/mpegurl)
-Excel spreadsheet, CSV (application/vnd.ms-excel)
-JavaScript (text/javascript)
-StyleSheet (text/css)
- You get the idea...
Input Details:
-Can accept [I]almost any javascript type: strings, numbers, arrays (which it will flatten), nodes, node lists, xml objects in FF2, functions (for which it outputs the source code), complex JSON objects, and dates. (whew, I think that's all of 'em...)
-if you want to output an element as html, or anything else as text, you can skip the mimeType argument.
Notes:
-You will most likely want to assign the output to a link href or the .scr of a script, stylesheet, or iframe, or to window.location.href.
-If you assign it to an iframe or object, it will load immediately.
-assigning it to a (<a>) tag will let you 'right-click, SaveAs' the file.
-clicking the link will open the 'file' in the browser just like a regular file.
-output an html document that has scripts, and they execute immediately.
-the cool thing about this is that the script will have a clean context. (no global variables from the parent).
-if used in an iframe- it can push to main page via window.top .
-if used in with an <object>, it will be completely private.
Caveats:
-doesn't work with IE yet.
-'saving As' doesn't offer a default file extention.
-there is 2kb limit for safari and opera URLs.
-search engines cannot see the links.
-XmlHTTP Requests from within usually don't work.
Examples:
To save my fingers, I will utilize the follow shortcut functions in these examples:
function el(tid) {return document.getElementById(tid)};
function tags(tid) {return document.getElementsByTagName(tid)};
//test
tags("a")[0].href=dataUrlStr("<b>Hello World!</b>")
//make a 2D array into an Excel SpreadSheet - (works with 1D lists also)
var grades= [["Subject" , "Grade"],
["Math", "A" ],
["English", "B+" ],
["Gym","C" ],
["Art","A-" ],
["Science","A+" ] ]
var exl=grades.join("
").toString().replace(/,/g , " ")
window.location.href=dataUrl(exl, "application/vnd.ms-excel")
//note: if data contains commas: loop through main, .join(' ') each index.
//execute script in a fresh enviroment:
window.testme="123456789"; //make a new global
var testJs="<script>alert('hidden window.testme='+ window.testme )</script>";
var fr= document.createElement("iframe");
fr.id="hiddenframe";
fr.style.display='none'
document.body.appendChild(fr); //add a hidden frame
alert("main window.testme="+window.testme);
el("hiddenframe").src=dataUrlStr(testJs);
//re-using the above example, pass existing functions to the hidden frame, and return the result.
var tJs="<script>";
tJs+=[tags, el].join("
"); //bundle a couple functions
tJs+="
alert('hidden window has '+tags('*').length)"
tJs+="</script>";
el("hiddenframe").src=dataUrlStr(tJs)
//open a playlist
var plTxt="#EXTM3U
#EXTINF:202,Minuet in G
http://www.mfiles.org.uk/downloads/beethoven-minuet-in-G.mp3"
el("hiddenframe").src=dataUrl(plTxt, "audio/mpegurl"
//open all the 'code' on this page as a plain text document.
function ob2Array(ob){var r=[]; for(var z=0; z<ob.length;z++){r[z]=ob[z]};return r};
function group( List, f) //applies a function (f) to an array and returns result...
{var z=0; Ray=[]; len=List.length;for (z;z<len;z++){Ray[Ray.length]=f(List[z]); }
return Ray;};
var codes=group(ob2Array(tags("pre")), function(x){if(x.className=="alt2")return x.textContent});
window.location.href=dataUrl(codes)
//make this thread into an rss feed
function tag(nd, tx){ return ["<",nd,">",tx,"</",nd,">"].join("")}
function dp (s) {var d = new Date();d.setTime(Date.parse(s)); return d.toUTCString()}
var X=PHP.htmlspecialchars
var chan=[]; var y = new Date();
chan[0]=tag("title", "CodingForums.com");
chan[1]=tag("link", window.location.href);
y.setTime(ajax_last_post+"000")
chan[2]=tag("pubDate", y.toUTCString())
chan[3]=tag("link", "http://www.codingforums.com/")
var codes=Group(ob2Array(tags("table")), function(x){
var i=[];d=""; p=d; t=d; l=d;j=d;a=0;
if(x.id.substr(0,4)=="post"){
p=tag("pubDate", dp(x.rows[0].cells[0].textContent.replace(/-/g, "/")));
t=tag("title", document.title)
l=tag("link", "http://www.codingforums.com/showpost.php?p="+tags("table")[5].id.substr(4))
ta=x.rows[1].cells[0].getElementsByTagName('a')[0]
a="<author>"+ta.href+" ("+ta.textContent+") </author>";
d=X(x.rows[1].cells[1].textContent.toString())
j=[d,t,p,l,a].join("
");
return tag('item', j)
}//end if
});
tags("a")[2].href=dataUrl(tag("channel", chan.join("
") + codes), "text/xml")
So, i think that should be enough examples to get going.
