Javascript Value Into Php Variable
May 29, 2003
document.write('<td align=left BGCOLOR="#D9D9D9">
<a href=prod_show.php code_no='+thenumber+'>'+theitem+'</A></td>');
I have this javascript code in a php page. I need to access the value of '+thenumber+' into a variable that PHP would understand so that I can carry the "thenumber" value onto the next page and be a usable php value.
I tried:
PHP Code:
document.write('<INPUT TYPE=hidden NAME="number" VALUE="'+thenumber+'">')
but this didn't work probably because I have no clue as to how to do this. Any ideas?

I've got a html doc with <embed src="url.svg"> in it
however, I'd like the source to be a javscript variable (which will
depending on an if, be a different filename on loading)
is this possible and if so, what is the syntax to put a javascript variable
inside an embed tag?

I have two events in a form that I am passing. One is to a javascript
function, the other is to the same .asp page only with another action
to show different data.
Onchange is calls the function updateclasses, which in turn reloads
another drop-down list. It also reloads the .asp page, which
refreshes the data. My problem is that it refreshes the second
drop-down briefly, until the page reloads, but then resets the form.
How do i pass this data to the .asp?
I thought in the .asp, I could just do something simple like the
following, but wasn't sure of the correct syntax. is there a better
way?
view = request.querystring("view")
if view = "" then
view = "SciLink"
else
%>
<script language="JavaScript">
updateclasses(form1, 0, Student)
</script>
<%
end if

I've got a URL in an include file like this :
<iframe src=http://www.blah.com?query=thevariable>
I want to be able to set 'thevariable' in the shtml page that calls that include and pass it to that string - I'm thinking that because I don't want to use php/asp that Javascript is the best way?
In PHP I'd do it like this :
<iframe src=http://www.blah.com?query=<?echo $thevariable;?>>
So how do I echo/insert the variable in the URL using javascript rather than PHP?

Not sure whether this should go in the JavaScript or VBScript/ASP section, but I'll try here anyway.
I have an ASP include file that contains both VBScript and JavaScript code. The VBScript processes some information and has an onChange event which calls a JavaScript function. Within this javascript function I want to access a recordset and retrieve a value using a variable from the javascript. Here's the code from the JavaScript section. Code:

<script type="text/javascript">
function HTMLEncode( text )
{
text = text.replace(/&/g, "&") ;
text = text.replace(/"/g, """) ;
text = text.replace(/</g, "<") ;
text = text.replace(/>/g, ">") ;
text = text.replace(/'/g, "'") ;
return text ;
}
</script>
Now i want to store the content of 'text' in a php string. Is that possible?

I'm creating a simple memory game in which the user has to make pairs
from cards. I would like the user to see the variable "trys" (the
score) update on the page dynamically (in a text box would be great).
I can do this by showing a msgbox every time try increments but this
is annoying to use. I have been trying for hours to get this to work,
using innerhtml. Code:

I'm trying to use a remote file for the purpose of setting the value of a single variable. It contains a single line of code:
var rev_date = "R10-03-07";
In the HTML, it is called like this:
<script language="javascript" src="http://some.domain.com/revdate.js"></script>
There is a function in the head:
function setRevdate() {
document.getElementById("revdate").innerHTML = rev_date;
}
In the Body:
<body onload="setRevdate();">
Then where I want to place the text:
<span id="revdate">--</span>
The problem is that the page loads and the onload event seems to happen before the rev_date string object is created and produces a "rev_date not defined" error. If I hit the browser refresh, however, everything works fine and the text is displayed between the span tags. It continues to work thereafter as long as the browser session is not destroyed.
How can I program this to force the browser to wait for the script to be read in and the variable initiated before calling the function?

For ease of future modifications on my page, I want to have a list of URLs stored in an Array, and I want to then use these URLs in an href tag. Something like this:
<SCRIPT>
menuURL[0]="page2.htm";
menuURL[1]="javascript://";
...
</SCRIPT>
<BODY>
<A HREF = menuURL[0] ........
How is something like this possible, as well as being fairly crossplatform, and intuitive? I've changed the syntax, and tried various other things to no avail.

I wish to use J.S. to obtain the screen ht and put this value into a hidden
field for posting. so that I can then use it in a php file.
A simplified script of what I am trying to do is below, but it doesnt work.
I have not used javascript much and I'm sure its straight forward.
<script type="text/javascript" language="javascript">
var ht = document.body.clientHeight;
</script>
<form action="my.php" method="post">
input name="screenht" type="hidden" value="ht"
</form>

I have a form that posts data to a PHP mailer page I have created. When
it goes to the PHP mailer page it reads some of the data and modifies
the page accordingly using Javascript (hiding certain divs, etc...). My
goal, is to take all this data after it has been processed by
Javascript and send it through my PHP mailer as it is currently
formatted.
If it helps any, the track I am on right now involves encapsulating the
Javascript processed block in a div. I am then trying to take the
..innerHTML data from that div and store it in the PHP $message variable
for my mailer. This won't work because PHP is server side. So, I moved
on to generate some Javascript code (with PHP) that sends all that
messy HTML data that its processed through a URL variable to then be
read by PHP. This doesn't really accomplish what I want as it cuts off
about a quarter of the way through my data......
Any ideas??
One thing I thought of but don't know how to do or whether it's even
possible is using PHP to view the source of the current page and store
that as the HTML to be e-mailed. Or, is it possible to do something
similar to .innerHTML with PHP?

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.

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'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
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 am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)
