This is probably a really simple question. Is it possible to initialize x amount of variables. Like someone enters 10 into an input box and it makes 10 variables called variable1, variable2, variable3, etc.How would you name them?variable + num = 0; ?
View 2 RepliesI've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list[i];
}
or outside a loop routine, like this:
var i;
var name;
for (i=0; i<list; i++)
{
name = list[i];
}
or are both the same....
As a programmer, i always try to practice good programming. I always
thought that by declaring and initializing the variable inside the
loop, i was creating a new memory space every time instead of just 1
time...
What do you think?
I run a carousel plugin which has initializing variables on my index page, which looks like:
Now what i need is an onclick event which tells the script to update the variable 'start' to '500' and then re-run the script without a complete page reloading....
You can use JQuery's data method (e.g. $('#MyID').data('MyVar', 'MyValue');) to easily store/retrieve information.
However, I was wondering if it is possible for my PHP generated page to add HTML tags that initialize the JQuery's data method variables. Regularly, I want server side variables to be accessible client side. It would be very helpful if I could initialize data method variables during PHP page generation.
If this is not possible, are there any suggestions on how to efficiently communicate server side variables to client side?
I've made a tabbing system with javascript which consists of a couple of functions and all I need to do is to initialize one of the functions from each html page the script is linked to.
Here is the function I want to initialize:
The parameter key would be the default selected tab and n being the number of tabs. So if I was to have 3 tabs with first one being selected by default I'd say change(1, 3).
I just need to know how to do this from the html file since I'll be using it on multiple pages and I don't want to have a different js file for each page.
My slide show seem to not be initializing I used a base from [URL] and tweaked it around to be exactly what I need and it won't start.
here is my js
var interval = 1500; //1.5 secs
var random_display = 0; //goes in order
//defines where the images are stored

I am loading a page dynamically using .load with jquery and then i have another button on that page that allows you to go back to the previous page using livequery click function. However, when I go back to the original page, none of the page functions defined previously are working anymore! Is there a way to force the browser to reinitialize the script? How does one get around this problem with jquery?

I want to make a hooverbox, which is shown when the mousepointer is not
moved for a amount of time.
When the hooverbox is shown, i will do a server request to retrieve the
information for the hooverbox.
I was thinking of using document.onmousemove and a infinit running while
loop comparing the mouse positions. Is this the way to solve it?
(pointers/samples are welcome ;-) )

potentialy 30-40. I need to store a bunch of data and thought about
using hidden iframes to do it but wasn't sure if this would bog down
my page or not. Opinions? I know this is not an IDEAL way to store
data but I'm at my whitts end and it sounds like a nice workaround
right about now!
I have
function dototal(){
tamount=parseInt(document.myform.amount1.value)+parseInt(document.myform.amount2.value)+parseInt(doc ument.myform.amount3.value);
document.getElementById('total').innerHTML=tamount;
}
The problem is if amount is blank it can't add it -- how can I change it that if it is blank it should treat it as 0?
