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?

View 2 Replies View RelatedI was wondering if there was a way to dynamically read a field input and respond to it later in the form. My situation is this: I have a question that asks how many workers are employed at a business. Later in the form, the user is asked to add as many workers as they have (section with information on each worker) ..Is there a way I can have something echoed or document.write above the latter section saying "Please add (Number of workers listed above) sections for each worker employed"

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.
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.

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
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.
How can I read the object's attribute's name ? I mean something like this:

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.

View 3 Replies View RelatedI'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.
