Have a look at this maths game I made. It tests you on adding, subtracting, multiplying and dividing and has three different levels.

Note-you must save the code below as mathsgamefinal.htm for the reset button to work.

Handling Maths In Strange Way?

Aug 25, 2010

I have javascript calculating the total price of all the products in a shoppping cart. The prices are in the format of 10.99 or 5.50 or 10 ete.g if there are five items bought for 10.99 and 1 bought for 10, the script will multiply 10.99 by 3, then multiply 10 by one, then add the two results.

The resulting number is sometimes right, but quite often it ads an extra '000000002' or so to the amount??

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 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:

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('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.

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:

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.

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.

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

<script>
alert( this.z );
alert( window.z ); // both equivalent, no error, but window.z is
'undefined'
</script>

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
hidden field and assign it a value based on the value of another variable

Right now it looks like:

("document.all.SM_MARK_10" + dateNumber + ".value")

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

document.all.SM_MARK_1001.value="XX"
document.all.SM_MARK_1002.value="X2"

etc.

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

Using JS To Pull Url Variables.

May 18, 2005

url example:

whatever.com/index.html?name=username&password=password&gender=male&age=18


function getE(){
var url_string = String(document.location);
var url_array1 = url_string.split('?');
if(url_array1[1]){
var e_array = url_array1[1].split('&');
for(i=0;i<=20;i++){
if(e_array[i]){
pullE(e_array[i]);
}
}
}
}
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..

firstly:
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];
}
