I need to create a variable out of nothing. From a database I extract an
item with a certain id. With this id I want to create a new variable.
For example:
id = 36;
"item"+id = new Array();
Now I get the message "Illegal left hand assignment".
I tried:
eval("item"+id) = new Array();
Is it possible to create a variable out of nothing?
I am trying to write a loop that will add 10 divs to the screen. Each
div will have an onclick event. The function that will be called
onclick requires a parameter. That parameter is dynamic based on the
index of the loop. In Firefox this is no problem. However in IE I get
some results that I wouldn't expect.
Here is my code:
for(var i = 0; i < 10; i++)
{
var linename = jsonObj.lines[i].line;
var childcountid = jsonObj.lines[i].childcount;
var lineid = jsonObj.lines[i].lineid;
var newdiv = document.createElement('div');
newdiv.setAttribute("id","main" + i);
if (navigator.appName == "Microsoft Internet Explorer")
{
//************ this is the problem area
*****************
newspan.attachEvent("onclick", function() {getCategories('main' +
i)});
}
else
{
newspan.setAttribute("onclick", "getCategories('main" + i + "')");
}
document.getElementById('container').appendChild(n ewdiv);
}
What happens is when the element is clicked the parameter being passed
to getCategories is always 'main9' IE always grabs the current value
of i, not the value of i at the stage of the loop that attachEvent was
called.....
I'm creating dynamic buttons and forms for a website and would like the form hidden when it's corresponding button is clicked. However, when I pass button and form name variables to my JavaScript that hides the form, the variables are not being recognised unless I explicitly set them. (e.g 1 and 2 as seen below).
In a nutshell the onlick event doesn't seem to like PHP variables !

I have a little problem that doesn't seem to be working. I'm trying to access a variable using its string name which is passed when the function is called Code: ie:
function a(varName, other crap...) {
document.getElementById("sometag").innerHTML = ['varName'].somevalue;
}
// I would call this function like so...
a("temp1", othercrap...);
The variable temp1 is set in another script file. I don't specifically know which variable I will be passing to the function a(), all I have is its string representation. I can access the values of temp1 if I specifically call it but I can't seem to figure out how to call it dynamically.
I'm working on a rather complex booking system for building European
trips, in a combination of SQL/VBScript/Javascript. There are tons of
query string variables that get passed back and forth between the
pages, and in almost every case, I can set 'em up fine, provided the
variables are in the link.
The page the *holds* the booking information, though, is problematic.
An example trip might include two European cities or towns with a week
in each in an apartment or cottage that the user selects from a dozen
or properties for each region.
All the information is on one page (all the dozen or so properties for
each weeks, available dates for the trip and for each , max occupancy
per property, pricing per property and per number of passengers,
etc...everything necessary to actually book the trip). If the user
changes party size or chooses a date, properties are hidden or shown
depending on max occupancy and/or availability.
So, a user sets their date and party size (or maybe just the party
size, or maybe has just cleared everything out to start over...) then
wants to view available properties so they can find one they like. The
current pax/date/etc. information is not in the query variables,
because the link was built at runtime.
If I build the link in an onclick event, it breaks if someone right
clicks to open a new page or tab.
I hate sites that disable right click menu. I hate sites where, when
you open a new page with a right click, it generates a javascript
error if the URL is created with an onclick event. I hate that using
an onclick to bring up the page means whatever is showing in the
status bar bears no resemblance to the page that is brought up when
you click on the link.
My client isn't worried about the non-javascript people for this use;
those people are referred to a free spiffy catalog, which frankly, is
how most of this client's customers book their trip anyway. I just
want to be able to carry the variables in such a way as to not break
the site if someone right clicks.
Anybody have any suggestions? Is it hopeless?
I'm building up a RSS reader. In this app, the user will have the option to add and remove urls in a list. What I need is to create a new variable, everytime the user submit the form with the url. The variable must contain the url.

I would like to display the number 1 at first and then 2. but this code produces number 2 for both alerts. I was able to achieve what i wanted with "new" constructor when creating functions but this is not a good practice and after all i am passing these functions as an event handlers and it can't be done with "new" keyword because it is throwing error. I think there are some solutions with arrays e.g the x would be an array of numbers, but i don't like it. Am i missing something important?
Anyone know how to get Javascript variables into PHP variables or a MySQL database? Full question in the PHP section.

I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:

I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total. Here is the bit that does the calculation:

number (see "VLANS") is inputed into my form.

I thought it was possible to send two variables in an URL like this:
print" <script type='text/javascript'>
document.location.replace('http://127.0.0.1/add_task.php?tk_request_name={$req_name}?tk_req_id ={$maxValue}');
</script>";
but I can't get them separately in add_task.php
is there something wrong with script?
I use this code in some other PHP code.
Lets say I have a variable declared as such:
var newVariable="opener";
How can I then use this variable to access the opener of 'window' ?
Meaning, I dont want to access it as such:
window.opener
but as: window.+newVariable
So it uses the contents of newVariable to access the opener.
I need this because I have a couple of variables which I need to concat to eachother as a string,
and this string in turn is the variable I need to access from window.opener.varSomething
where varSomething is the variable that stores the variable I need to access.
I use ASP to obtain data from a database and I have a piece of javascript
code I use on my website. I want to use the database variables in my

similar to what I'm trying to do.
<%
strFirstName=session("FirstName")
strLastName=session("LastName")
%>
The javascript code I want to use the variables in.
Items[1]=["First Name", strFirstName,""]
Items[2]=["Last Name", strLastName,""]
Please help or point me to a website with this solution. Thanks much for
your help.

Not sure if php is the best solution or maybe javascript. ( or both.)
I am writing a litle script that will go to my mysql table and take out 20 rows ( from about 10,000 rows ) based on the WHERE statement.
Then I want to step through these 20 rows displaying just two filds in this fashion:
First, I want to display one field in a "box" ( using divs and css ) then wait for a form input. Then while keeping the first displayed box and field display the second field in a similar box a fee lines below. Wait for a form input update some data.
Then onto the next row.
If I use javascript then I could keep all the processing on one page and not have
to have server refreshes.
But how do I get these those array elements from $row['field1'] and $row['field2'] into javascript vars ?
Is this the best way to do this ?
Or would php and having a couple of extra trips to the server for form processing be better ?
