Defining New Opener
Dec 21, 2002I 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...
got it?????
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.
Defining Pictures In An Array
Jun 15, 2006I 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.

Function Defining Index Of Array?
Mar 24, 2010Code: function initArray() {
this.length = initArray.arguments.length;

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?
Defining Preload Var For Composite Images
Nov 13, 2006I 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.
Defining Array Elements With Keys
Mar 13, 2010I 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.
How To Avoid The Execution Of A Function At The Time Of Defining.
Mar 18, 2007How 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.
JQuery :: Defining Dynamic Selector With Variable?
May 20, 2010How 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?

Defining And Display Variables With Switch Statement
Oct 19, 2010I'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.

var large = document.calc.large.value;

Defining Div Width Equal To Undefined Amount Of Images Total Width?
Oct 4, 2010let 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.
View 6 Replies View RelatedCannot Move Input Focus To A Cell After Re-Defining The Cell
Sep 15, 2011I have a javascript program that uses a HTML table as an Excel-like grid. The user can use arrow keys to navigation the grid. When the user selects a cell and then hits <Enter> key, the program turns the cell from read-only to editable (an input box), and select all the text in the input box. When the user hits <Esc>, the program cancels the changes that the user has made and turns the cell back to read-only. So far so good. The problem is that as soon as the user hits <Esc> key and turns the cell back to read-only, I find that I cannot move the input focus back to the cell any more. Actually I cannot move the input focus back to _any_ cell in the table. When this happens, the user cannot use arrow keys to navigate the grid any more (like the grid has lost the input focus). The user needs to use the mouse to click at a cell in the table to get things working again.
The user can get around with this problem by un-selecting the text from the input-box before hitting <Esc>. But this is not something that I expect the user to remember to do. I need a way to fix this problem. I tried the logical thing and programmatically un-select the text before turning the cell back to read-only. But this actually made thing worse - this causes the workaround to stop working.
The only browsers that I have tested this program is IE6 and IE8. I have not tested this in any other browser.
Attached is a simplified version of the program that can show this problem in action. This simplified program first adds an empty table on the web page, and then creates an instance of the CEstGrid class that takes care of the grid. CEstGrid will add two rows of test data into the table with two columns in each row. The user should use a mouse to click at one of the cell, and the cell should be highlighted. The user uses arrow keys to navigate the table. When he reaches the end of the table, he will wrap around to the other side of the table. Let say the user reaches the cell in row-1 column-2, he hits <Enter> to change the cell to editable. He will find the text in that cell to be highlighted. When he hits <Esc> at this moment, he will find that he cannot use the arrow keys to navigate the table any more, and this is the problem. Please rename the test program from .TXT to .HTML to test it.
