I wish to access several pictures on my page by defining them as an array. This way I can either loop through them or access them by array index.
What I am really doing is writing my own picture gallery and slide show. The reason I am doing this is so that I can have my web page look exactly the way I want. In addition, it is an excellent way to learn Javascript.
Code: function initArray() {
this.length = initArray.arguments.length;
for (var i = 0; i < this.length; i++) {[code].....
For the above piece of code, does the function 'function initArray()' just predefine the array that is written right after so that it's first array index starts at 1 instead of 0?
I would like to have an array and define which element goes to what key. Something like this:
Code:
var test = [][];
test[0][0] = "foo";
test[0][1] = "bar";
However I am wondering if its possible to write it in one statement? Something like this:
Code:
var test[0] = [
[0] => "foo",
[1] => "bar"
];
The code up doesn't work of course.
What's the difference between defining a variable with 'var' before, versus defining without it?[code]

View 1 Replies View RelatedI have just created an 'open window' function for an animated page. It opens the current animation from the current page into a new window, and lets the user change the 'opener' animation while the new animation in the new window continues, sychronised with the opener.
As the opener contains the clock for sychronisation, I can only use the animations from that page (and I have a few pages of small animations). I can let the new animation on the new page continue with its own clock if the opener is closed, but what I would like is if a new animation is started from a new opener, then it tells the existing opened window the new page speed...

trymy rhythm pages
follow steps.....
1; open new window
2; click on drum in new window to turn on
3; start rhythm by clicking on hands in main window
I can change between rhythms, so long as I stay on the main page. The problem is when I change the main page to go to other rhythms I loose the sychronisation.
I can go to another page(from opener) and put a new rhythm in the current new window, but I would prefer to keep the old rhythm and sychronise.

View 3 Replies View RelatedI'm trying to solve a problem for which I think the solution will be

I have built a function that allows users to select a color tile and trim option for a cooking range. Here is a code snippet showing the function:
var color, trim, description;
function displayRange(selectColor, selectTrim, showDes)
{
var rangeName;
if (selectColor != '')
color = selectColor;
if (selectTrim != '')
trim = selectTrim;
rangeName = "images/cluny1400" + color;
if (trim == 'chrome')
rangeName += "_chrome";
rangeName += ".jpg";
var rangeDescription;
if (showDes != '')
description = showDes;
rangeDescription = description;
document.getElementById('rangePict').src = rangeName;
document.getElementById('rangeDes').innerHTML = rangeDescription;
}
Based on the users selections the range image in the selected color and trim is loaded into the interface. My problem is this:
The selected image is made up of three elements, based on the users selection, color and trim and the .jpg extension. This function works well.
However, I cannot work out how to use the image object to preload the images (of which there will be over 34). Normally you would assing a var to hold a new instance of the image object and then assign the src property to the image url. But how do I do that when the var rangeName is composed of three elements. I cannot use a simple var and then call that var in the function.
I have this code snippet, that illustrates my problem:
// create function to preload images
// eliminate older browsers by checking for image object support
function preload() {
if (document.images) {
cluny1400au = new Image(478, 314);
cluny1400au.src = "images/cluny1400au_fw.jpg";
cluny1400au_fw_chrome = new Image(478, 314);
cluny1400au_fw_chrome.src = "images/cluny1400au_fw_chrome.jpg";
}
}
The vars cluny1400au and cluny1400au_fw_chrome would be fine if I could use them in the function to call the images, but I don't think this will work as I believe that you have to use the same var name in the function as in the image object.
Can anyone tell me how the cluny1400au = new Image(478, 314); and cluny1400au_fw_chrome.src = "images/cluny1400au_fw_chrome.jpg"; should be constructed to work with the function.
Here is an html snippet from the page to aid clarity:
<body onLoad="preload()">
<div id="wrapper">
<p><img src="images/cluny1400_bw_chrome.jpg" name="rangePict" width="478" height="314" id="rangePict" /></p>
<p id="rangeDes" name="rangeDes">Description</p>
Thank you in advance for any help.
How to avoid the execution of a function at the time of defining.
Here i am giving the details.
I am creating the following div container through DOM.
<div id="content">
<a href="#" onclick="displayDiv('content')" Click</a>
</div>
The Code is:
var category_list = document.getElementById('category_list');
var dom_div = document.createElement('div');
dom_div.id = 'content'
var dom_link = document.createElement('a');
dom_link.href ='#'
dom_link.onclick = displayDiv();
val = document.createTextNode('Click');
dom_link.appendChild(val);
dom_div.appendChild(dom_link);
category_list.appendChild(dom_div);
The displayDiv Funcion
function displayDiv()
{
dv = document.getElementById('content'); //Here is the error.
}
The Problem is when the following script:
dom_link.onclick = displayDiv('content');
is executed it is calling the function displayDiv(name)
Here we have the code
document.getElementById('content');
which throws the error.
The reason is the div container is not yet created.
What I need is the function should be called only on the click event. It should not be called while I define it to the Click Event. (ie it should not be called at the time of defining)
How to achieve this.
How can I dynamically specify a class value to use in a selector? For instance, I have a number, and I need to identify an element that ends with that number. In this case, there are four divs that have class values of
my_id_0
my_id_1
my_id_2
my_id_3
I have a 0 (obtained previously in the code) stored in the value tabId, so I want to get the values of the class attribute for <div id="my_id_0">. How do I create my selector? I tried
$("div# parent_element_id #my_id_" + tabId).attr("class");
but it comes back as undefined. Do I need to define it as a variable and put it in theelector that way? Or is there another way?
I'm trying to define a selector as a global variable and it keeps coming back undefined. I tried creating a namespace for it but had no luck. I would like to be able to reference the sliderRange, currentMin, currentMax globally.
SLIDER.range = $('#price-slider').slider('option','values');
SLIDER.min = SLIDER.range[0];
SLIDER.max = SLIDER.range[1];

I'm trying to code a script that will display an approximate postage price based on different combinations of variables, but the numbers I defined for each case aren't reflected in the text box. I'm using a switch statement for all the different combinations of options, which the user will choose by selecting check-boxes. (Additionally, I know that this code probably isn't a very efficient way of doing what I'm doing - how to improve it.) I've attached all the relevant parts of the code, including how I defined variables originally.

I'm new at Javascript, and have written a script for a series of random
roll-over button images, but one thing I would like to add is a function
that checks to make sure that there are no duplicates in the randomly
generated variables that choose the pictures.
Can anyone give me a hand with this? One other thing I can't seem to figure
out is how to manage the "onLoad" aspect of caching my roll-over images (DW
has locked the <body onload> function into a template, so I can't mess with
it...). so my rollover graphics are grabbed from the server in "real time"
during mouse-over, which is a bit "goofy" and "slow" in terms of instant
rollover effect. I'm sure that there is a much more efficient way of doing
this, but I've been able to learn a lot by tweaking DW's way of doing
things, so it's not a total loss.
In an external JS file, I set up a series of 10 random variables using the
Math.random and Math.round functions like so:
var btn0 = Math.random()*100;
btn0 = Math.round(btn0);
var btn1 = Math.random()*100;
btn1 = Math.round(btn1); .... etc for 10 buttons
Then in my page, I piggy-back onto Dreamweaver's built-in roll-over
handlers, like so (to write the instances of each rollover image);
<script>document.write('<a href="link1.htm" onMouseOut="MM_swapImgRestore()"
onMouseOver="MM_swapImage('pic1','','images/btns/'+btn0+'b.jpg',1)"><img
src="images/btn/'+btn0+'a.jpg" name="pic1" width="80" height="100"
border="0"></a>');</script>
For this particular page, I'm pretty much stuck with DW's coding because
it's locked into a template that governs my site navigation. Thanks for any
pointers or help ...
What is the javascript for reloading images upon the loading of each
page on a website. Also, how do I implement this in the HTML.
Should I just make this a small video, or will JS be able to handle around 25 pictures without being really slow?

let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.

I will show you how to get rid of <a> tags to put links on pictures.
When you want to put a link to another page on a picture, you type this
kind of HTML code :
<a href="page.html" style="text-decoration:none;" alt="funny things....">
<img src="img12.gif" alt="funny things ..." border="0"></a>
But when you click on the image, you can see a dotted border around it.
If you type this instead :
<img src="img12.gif" alt="funny things ..." border="0"
onclick="this.location='page.html'" style="cursor:hand;">
I think it is better, especially when you have frames in your website.
