Unless you're working IT in a penal colony, I suspect that what you really mean is that you choose to serve broken pages or no content at all to users who don't have JavaScript enabled, whether by choice or network requirement or software availability. It's an interesting decision, excluding browsers with JavaScript turned off. I can see making it in cases of specialty audiences, such as the aforementioned penal colony, customized intranets, and others where all of the user agents are not only predictable but legislatable. For public websites, I feel we need to set barriers to entrance only when necessary -- and when is that? -- consciously and deliberately, focusing not so much on Look at the cool things we can do with JavaScript! but Whom shall we exclude from this site? Look a user in the eye, say, You can't come in, and reflect on how cool that is. Although I still love to write client-side script, most of the energy I used to expend on JavaScript I now devote to PHP. The server is the great leveler of the playing field, rendering our pages accessible to all user agents *if* our designs are sufficiently clever. These days I mostly add JavaScript to perform functions that are already performed server-side by PHP, purely for the advantage of speed, but my best pages perform perfectly with JavaScript turned off. Aside, the whole client-side/server-side debate depends on today's internet connection response time being as slow as it is. In a few years a seemingly sexy technology like Ajax, which appears useful today in pages so heavy with content that whole-page reloads seem onerous, will be one of the unbelievable jokes of yesteryear, like RAM measured in kilobytes, 8 floppy discs, and punch cards.

Well, I asked you for the actual (JS) code you're using (the one
that didn't work in all the intended browsers), that way someone might
be able to help you (I will if I can)
Array.push(), Array.pop(), Array.shift(), Array.unshift().
Ok, so what are your intended browsers? According to what I found,
these functions are part of ECMAS 3 standard, and are available in FF
1.0, Netscape 4, e IE 5.5 (unshift until IE 6) --as always, M$ gives the
problems.
You might try to implement them yourself, such as...
// object detection for shift function
if ( undefined == Array.prototype.shift ) {
Array.prototype.shift = function( ) {
var val = this[0];
for ( var i = 0; i this.length - 1; i ++ ) {
this[i] = this[i + 1];
}
this.length --;
return val;
} // shift()
}
// object detection for unshift function
if ( undefined == Array.prototype.unshift ) {
Array.prototype.unshift = function( ) {
var args = arguments,
len = this.length + args.length;
this.length = len;
for ( var i = len - 1; i = args.length; i -- ) {
this[i] = this[i - args.length];
}
for ( i = 0; i args.length; i ++ ) {
this[i] = args[i];
}
} // unshift()
}
var x = new Array( 'z', 'b', 'c', 'd' ),
y = null;
document.write(rarr; + x.toString() +br /\n);
y = x.shift();
x.unshift('A', 'a');
document.write(rArr; + y + rArr; [+ x.toString() +]);
Note: tested only in Fx 1.5.0.3 (as _shift _unshift) with secuential
arrays (and not associative/hash arrays)
I thought that if I used Ajax, php could use its push and pop, shift and
unshift functions, but not all browsers support the asymetric requests.
Well, that seems too complex to solve your problem, but if you want to
try it, you may use the same object detection above and implement
those methods with PHP (e.g. unshift in IE 5.5, or all of the functions
you mentioned in IE 5.0)
I do screen in the server. But I force the user to have javascript
enabled and force the form to submit using javascipt, and have a unique
id as a javascript variable
that is sent along with the form in a hidden field to identify the
source of the form data. I never use get requests unless they are
appended to anchor tags, even
in forms that are not processed by the server (I.E. running javascript
code with user supplied arguments to functions via form fields, in which
case an action attribute
isn't even necessary, and like wise a post or get method).
It's basically the same problem, you shouldn't rely on javascript for
your page to actually do something. If I don't have JS enabled (for
whatever the reason) I won't be able to do anything on it. JS should be
used only to _add or complement_ functionality.

You say that not all browsers support the javascript functions you pretend 'scuse me, did i pretend to use something?? to use, and that not all them support Ajax either. That sounds just like saying that not all browser will have javascript enabled --that's why you shouldn't rely on javascript Although, this isn't a javascript list, why don't you send whatever you were trying to solve this issue? the code that uses JS functions not supported for all the browsers that will potentially run the script (as well as what these browsers are) Most likely someone will be able to help you this way. Thanks for the attitude. jk jekillen wrote: Hello; i'm scratching my head with a difficulty. The situation is this. A script begins with one indexed array (not associative) and one other indexed array with the same values in a different order, the final order. I want to create an interim array and progressively re order the array until it matches slot for slot one of the original arrays. At this point the script is considered completed. One important factor is that I'm looking to write this in javascript and the interim array will be altered by the actions of a web page user. Why am I asking the php list? Because I have a better chance of getting an answer here. I'm not looking for help with javascript, specifically, just how one would go about this task. Answer with php code and some theory if you wish and I will try to translate it into javascript. Some javascript functions I might use aren't supported in all the browsers that will potentially run the script. I might resort to using Ajax and let php keep track for me. But, then again not all browsers will do the Ajax either (as I understand it). -- Atentamente / Sincerely, J.

Client-side security isn't. Your server has no way of telling if the data it's receiving is from a properly setup client that did the correct JS filtering, or if it's from someone writing as simple bot/script/program that's just sending GET and POST requests to you.
