In What Situations Would You 'Pass By Value' And 'Pass By Reference'
Nov 20, 2007I have been trying to grasp the whole 'Pass By Value/Reference' thing for a few hours now. From what i can make out:
Passing by value will make a copy of the value, pass it as a function argument and the function will store the changes, the original value is not affected. So for example:
JavaScript Code:
var cost = 145;var postage = .3;var a = function() {return cost + postage;} //Using an Anonymous function for this
If you was then to pass the value of 'a' to a function argument it would copy and not change the original value.
If you pass by reference it will change the original value. When you pass a reference to a value through a series of different functions and the value is constantly being changed the change happens on the original value and can be seen outside the function.
The problem is i cannot think of how or why this would be used. I havn't got to develop many large applications so im trying to think of a few situations when passing by reference would be used.

Pass Url To A Popup
Sep 6, 2006In my program the user clicks on a link and using the window.open
function, opens a new window.
I pass a url to the new window like this:
<a href="#"
onClick="window.open('../quotescreenwindow.php?enroll_id=enrollwindowprime. php',
'WindowC', 'width=750,height=800,scrollbars=yes');">
In the new window that just opened called quotescreenwindow.php, I
have a button that when clicked, should open yet another window called
enrollwindowprime.php (this is the variable I am passing after the
question mark).
What I cannot do, is to grab this variable that I am passing to the
first window I open and use its content to open the next window.
I am not very experienced and have been piecing this together from
various web sites.
To simplify all of this:
Screen A Opens Popup Window B and passes it a variable with a url
inside of it.
Popup Window B wants to use the variable with the url to open Pop Up
Window C.

Ajax :: How To Pass The JS
Dec 15, 2009I have an ajax script that sends a request to a servlet for information to be inserted into a table cell. The servlet then handles the request and replies with something like this:(I took the liberty of removing all the out.println tags)
<script language='javascript' src='whiteWine.js'></script>
<table align='center' border='0'>
<tr>
[code].....
For some reason, however, all the scripts functions cannot be found on the page. If I attach the
<script language='javascript' src='whiteWine.js'></script> on the page then the functions work, but they are used as polymorphism and incorrect information is shown. (There are 3 different scripts with the same named functions, but different implementations).Is there a reason why ajax can't send across scripts?
Trying To Pass Variables In The URL?
Mar 25, 2010I'm sure there is a really, really simple way to solve this issue. I'm just not a programmer so I don't know it off the top of my head. I have this script ext.php that accepts a variable ref.[URL]..The problem is that there is also a '?' in the variable ref that I'm using. Like so:[URL]...I suspect because there is another '?' in variable ref, ext.php has a problem with it. I cannot change ext.php or sitename.asp.
So my question is, how can I make this work properly via the url? I've tried using %26 for the '?' as well as the & html escape code, but it still doesn't work.

Pass Arg To Function By Value?
Jul 24, 2009ok I have a unique problem, I need to pass a variable's value to a function instead of a pointer (reference) to the variable as by the time the function is called (because of the SetTimeout function) the variables value has changed.
I realise that may not be so clear so I've included the long explanation below, please bare with me ... =p
I have a 2 dimensional menu, when you hover over menu item it animates. to exaggerate that it is a menu (from the design it's not immediatly apparent) I decided to add a simple animation for when the page loads where it loops through each menu item and animates it in sequence.
each of the sub menu items are stored in a 2D array (SubMenuItemsArray) and I get the "wave" effect by having a short (60 millisecond) pause between each animation (achieved with Window.SetTimeout).
heres the code, I've set i and j to 0 after the loop to highlight the issue.

Pass On Values From Drop-down Box
Nov 25, 2005I wonder if anybody can give me a hint about what I have to do to get
this working: I am creating a drop down box using the script below. The
result is two text fields; now I want to pass those values, which come
from the drop down box, to the next page. The next page should then
simply look like this:

And the values should be the ones from the drop-down box...
I have been staring myself blind about how to get this accomplished.
Would be more than grateful if somebody could have a look...here is
what I got so far: Code:
