Using Variables As Variables

Apr 9, 2007

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:


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.

PHP Variables To Javascript Variables

May 6, 2006

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 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(
$length = count($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:

2 Variables In An URL

Apr 4, 2006

I thought it was possible to send two variables in an URL like this:

print" <script type='text/javascript'>
document.location.replace('{$req_name}?tk_req_id ={$maxValue}');

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.

Getting Variables From PHP?

Feb 22, 2011

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 ?

Dynamic Variables

Jul 23, 2005

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?

Undefined Variables

Feb 21, 2006

Looking for clarification of undefined variables vs. error in
JavaScript code.

alert( z ); // this will be an error, i.e. an exception

alert( this.z );
alert( window.z ); // both equivalent, no error, but window.z is

why is it that 'z' alone without the global object generates an error,
shouldn't it also be undefined? for example if i did

z = 0;

the javascript interpreter knows to create a global variable z

Creating Variables On The Fly

Jul 20, 2005

how you would piece
together a variable name and then assign it a value. I want to create a

Right now it looks like:

where dateNumber is an already defined integer. What I want is to say



based on that value of dateNumber. Any way to do this easily?

Using JS To Pull Url Variables.

May 18, 2005

url example:

function getE(){
var url_string = String(document.location);
var url_array1 = url_string.split('?');
var e_array = url_array1[1].split('&');
function pullE(val){
var useVal = val.split('=');
alert(useVal[0]+" == "+useVal[1]); //display purposes

this would alert in order:
name == username
password == password
gender == male
age == 18

where useVal[0] is the element name and useVal[1] is the value.

URL Variables & Strings

Nov 2, 2005

I was wondering if someone would be so kind as to help me out in understanding a few things about sending a variable through a URL..

i have two pages on page1.html i have a link which is:

window.location = "page2.html?name=yournamehere";

on page2.html how how would i be able to access the variable "name" ?

i know the following code works for strings, but i want to be able to directly access the variable that has already been assigned a value.

function parse(){
var Loc=this.location.toString();
var URLarray1=Loc.split('?')[1];

then I get error: timeStamp is undefined. Why? I defined it as a global variable within openWindow. Am I just doing this wrong?

Spaces In Variables

Nov 4, 2006

I have a line of code:

What I require is a bigger space here:

var cdate=dayarray[day]+", "+montharray[month]+" "+daym+" "+year+" "+" "+" "+hours+":"+minutes+":"+seconds+" "+dn+""

I tried +"xxx"+ (where the xs are three spaces) but that didn't work either.
