Read A Pre Tag With Xml ?
Apr 5, 2010
I want to read a pre tag with xml. I am working client side. I have tried everything. The <title> tag gets lost with innerHTML(ok in FF only). I tried traversing the dom and putting in the tag names but the title tag is ignored. I am trying to syntax highlight this. Everything works if I do not use certain html tags. How do I get raw text from the pre? The text would come from one of two sources, a server or inputted into a textarea by the user. It is dynamically placed in the div tag and then processed.

I have a database with information of my users, lets say their date of
birth.
I want them to be able to go to my site, and login with a username and
password, after which they get to see what their date of birth is (according
to what's stored in the database).
I want to upload a textfile named "userinfo.txt" structured like:
<username>;<password>;<date of birth>, for example:
"johndoe";"johnpass";"1985-11-25"
"marydoe";"marypass";"1986-02-12"
What's the javascript to have a "username/password" box popup, and when a
valid name/pass was entered show the appropriate date of birth?

I use Microsoft.XMLDOM load() method to load an XML file into memory
and display
some elements in the browser.
However it apparently locks the file, since I get this error message
whenever a Visual Basic application concurrently tries to add an
element to the same XML file:
The process cannot access the file because it is being used by another
process.
I would like not to lock this file, but open it in read-only mode
instead. In fact the browser simply needs to read its content, it
doesn't need to modify it at all. As a consequence there is no reason
to lock it.
At the same time, I need to access it from the VB process.

I have an external file, TestVar.js with a single line.
NewsA("This is a test.","test.pdf","TEST")
Within my HTML I wish to use the array variables from TestVar.js, but
can't seem to get them loaded for use. The following is what I have,
but doesn't work. If I directly place the NewsA array in the script
instead of trying to call it from the js it works just the way I want
it, but I really need the external file. What am I doing wrong? Code:

I need to parse a response from a cgi script. The response is te
following:
<HTML>UID=834<HTML>
the call for the cgi is http://<server>/cgi-bin/getuid?FILE=uid.html
Now I need the UID in a javascript.
1) call cgi
2) put UID into a variable
How do I have to do that? If I call the cgi the response will be
displayed on the screen but I just need it in the variable.

I'm trying to read a cookie that I've set with php with javascript. The cookie is for storing the username when logging in to a site. If the cookie has been set I want the focus in the inline popup to target the password field so that the user doesn't have to tab down from the username field of the login form.
The php script stores the cookie perfectly:
if (isset($_POST['remember'])){
$expire = time()+60*60*24*30;
setcookie("login_username", $username, $expire);
echo $_COOKIE['login_username'];
} else {
if (isset($_COOKIE['login_username']) || isset($_COOKIE['password'])){
$expire = time()-3600;
setcookie("login_username", "", $expire);
}}
The javascript:
if (targetfocus == 'login_username'){
alert(readCookie('login_username'));
if (readCookie('login_username') == 'username'){
targetfocus = 'password';
}}
$("#"+targetfocus).focus();
...
function readCookie(name) {
var cookieName = name + "=";
var cookieArray = document.cookie.split(';');
for (var i = 0; i < cookieArray.length; i++){
var cookie = cookieArray[i];
while (cookie.charAt(0)==' '){
cookie = cookie.substring(1,cookie.length);
}if (cookie.indexOf(cookieName) == 0){
return cookie.substring(cookieName.length,cookie.length);
}return null;
}}
But when trying to read the cookie in the javascript code I receive null when I put an alert to the code. Why won't the javascript find the cookie? Is it because I'm running the site localhost on my laptop? Does that have an effect on cookies?

While writing a look up for internet terms script for a site, I found the script will not read the second value in this array, I could make wl[1] a null value but would like to know what is happening if possible. All of the other elements seem to be ok!
function search(){
wl = new Array()
wl[0]="applet - An Applet is a small application etc";
wl[1]="Bug? - Null but why";
wl[2]="cgi - CGI or Common Gateway Interface allows etc";
wl[3]="browser - A Browser is etc.";
myWord=document.theForm.txtWord.value;
myWord = myWord.toLowerCase();
for(c=0; c < wl.length; c++){
currentWord = wl[c].split(" ");
alert(c + " MyWord " + myWord);
alert(c + " Current " + currentWord[c]);// The alert box = 'Current -' when wl[1] is read.
}
}//end of function

Does anyone know how - or better yet - have a sample of how to extract information from a meta tag in an HTML document's head tag using Javascipt?
I have looked at the DOM with Firefox - but it seems so long. I'd be really interested in a better way. If someone has the javascript for walking through the DOM, that would be cool too. I havn't built it yet.

so I'm interested in knowing if there's a way through javascript, php whatever to be able to read the pages current URL. For example when the page loads and knows the difference between www.mySite.com/ and www.mySite.com/#aboutI'm trying to find if there's a way to use the '#about' as a variable for a particular script instead of just it being dummy text on the end of the URL.

I thought this would be simple for me to work out, but I can't seem to find reference to it. I'm flexable on how I call a URL, thus, if I have any one of the following:
http://www.mydomain.com/index.html?err=dup
http://www.mydomain.com/index.html?err=1
http://www.mydomain.com/index.html?dup
How can I read the value to the right of the question mark?
I want to create a javascript function which reads the url, and, if the url was passed an arguement, it acts on it (namely, displays an error message)....

If I have a link to a URL such as <a
href="http://www.mysite.com/somecode.htm?5">Link1</a>, and if I include
javascript in the somecode.htm file, is there a javascript command that I
can use which will read the argument 5?
For that matter, is there anyway to send an argument to the javascript code
of an html link you are calling. Server scripts are not an option for me.
For example, assuming that index.htm contains 50 links, I would like each
link to point to the same html file, but I want that javascript code in that
html file to execute something different depending on which link was
clicked.
My only other alternative would be to create 50 similar html files which to
me looks like amateur or bad coding.

I'm using a java-script in a HTML-page. Part of the script is the line:
var limit = 1136 - 1101;
The value 1136 is a counter and changes permanantly. In VB I can write a
routine which prints the actual value to a fule called COUNTER.TXT.
Can I change my JavaScript in such a way that it reads the value of the file
COUNTER.TXT?

I've code like this:
var x =window.open('http://localhost/canvas.html','myokno')
var w =x.width
Permission denied to get property Window.width
var w =x.innerWidth
Permission denied to get property Window.innerWidth
why i can get properties of new created window???
The second problem is much more important:
i want to get element which id is "canvas" and it is in new window so i do
like this:
var canvas = myokno.document.getElementById('canvas')
ReferenceError: myokno is not defined
var canvas = x.document.getElementById('canvas')
Permission denied to call method HTMLDocument.getElementById
so i start working on the problem and:
var can = x.document
can
[object HTMLDocument]
var can2 = can.getElementById('canvas')
Permission denied to call method HTMLDocument.getElementById
what i doing wrong?

I seem to remember being able to do this, but I can't seem to find out
how I did it before...
Basically, I have styles defined by class in a stylesheet, and I need
to read the "width" style. obj.currentStyle.width works just fine in
IE, but Firefox doesn't recognize it.
document.defaultView.getComputedStyle(obj,null).ge tPropertyValue('width')
gives me the actual width (just as obj.offsetWidth does), not the width
style assigned by the stylesheet.
Because the elements are cells in a table row, the rendering of the
table is causing the actual width to vary from the assigned width
style. So, how can I get the assigned width style in Firefox (and other
browsers)?

I need to make a javascript read a web directory from a remote site (ie
"http://remotesite.com/images") (The remote die does not have an index.htm and does have directory listing enabled)
I have seen many samples but they all use frames or iframes, all I want
is a method that you can say:
<body onload="readremotedir('http://remotesite.com/images');">
and the method would get the directory listings and populate an array
var Pic = new Array()

I need to read xml data from [URL] which is not on my server. Is that possible, without using a php-api-proxy due to cross-domain-policy?
Despite that, the xml from that api is not valid and can therefore not be read.

I have a project that I need to read some data from an XML file.
Something like:
However, since JS is a client side script so it can't read from client side, is there any alternate way to do this? I am thinking to create a "Data" class, and many "Data" objects, is this an elegant way to do it?
