Some Dynamic Creation Of Stylesheets
Oct 22, 2007
I have reason to want to be able to change a Firefox stylesheet rule dynamically. I have found, doing google searches, sites which tell you how to create stylesheets dynamically or just add and delete rules, but none of these pages procedures have worked in my Firefox. Some have worked in Internet Explorer. Most have claimed to be cross browser. An example of one which I had high hopes would work can be found at this link.. The code they give you near the bottom of that page is posted below with the original background color changed to red and some text to see the background color put in the body of the page. In other words I pretty much just pasted the code found their in the head portion of my HTML page.
Attempting to troubleshoot why this code is not working if I use the old alert message method and put an alert message between the lines "var mysheet=document.styleSheets[0]" and the line "var totalrules=mysheet.cssRules? mysheet.cssRules.length : mysheet.rules.length" the mysheet variable region out as being "object CSSStyleSheet", however if I use the newer step through method with firebug it reads undefined. So I am totally baffled. Code:

I'm building a DIV dynamically and putting a P into it like so:
var oDiv = document.createElement("DIV");
var oP = document.createElement("P");
oP.style.backgroundColor = "green";
oP.appendChild( document.createTextNode("some sample text") );
oDiv.appendChild(oP);
oDiv.style.position = "absolute";
oDiv.style.left = "100px";
oDiv.style.top = "100px";
oDiv.style.width = "200px";
oDiv.style.height = "150px";
oDiv.style.backgroundColor = "blue";
document.body.appendChild(oDiv);
The problem is that FF doesn't put the P in the top left corner of the
DIV. Rather it seem to push it down by a line height. Is there some
white space sneaking into the DIV? How do I get the P right into the top
left corner?

can anybody tell me how you can create a new stylesheet inside a
(X)HTML page with JavaScript and Firefox, if the stylesheet is only
available as a variable value, like:
var CSSStyle = "rect {fill: lightgrey;}
circle {fill: red;}
polyline {fill: none; stroke: red; stroke-width: 0.3;}
text {font-size: 2.5px;}
text.text-x-axis {text-anchor: middle;}
text.text-y-axis {text-anchor: end;}"
So far, the only workaround I found, was to link an empty stylesheet to
the page
<link rel="stylesheet" type="text/css" href="./empty.css"/>
and then use the insertRule method on this stylesheet for every single
rule from the variable (indexOf('}') / substring()).

I created the checkbox using this code:-
var chkbox = document.createElement('input');
chkbox.type = 'checkbox';
chkbox.name = 'disrow';
Now when i tried alert(document.forms['actionsForm'].disrow) I am getting undefined.

I'm creating some links with PHP and here is the code for that:
Code:
<br><a id="add_to_cart" href="add_to_cart.php?pic_id=<?php echo $resultsetnewpic['pic_id']; ?>" class="under_pic_cart">Add to Shopping Cart</a>
There is a while loop to keep adding them but wanted to keep it simple. So right now there are three links that get created. I'm trying to find out the value of these links so I can add things to a shopping cart for the user. I have the following jquery to do this:
Code:
$(function() {
$(".under_pic_cart").click(function(){
alert("it gets here");
[Code]....
This part works fine. However how can I get the href value of this and then once I have it basically split it after the = sign to get the value I'm really looking for?

I have a small number of functions on an object and for every function I wish to make a different function that calls the original where the this can be passed as a parameter. I am making a library and this is a convenience method for people who don't know about call/apply.
Currently (one of) my function looks like this:
function _find(){
return find.apply(arguments[0],Array.prototype.slice.call(arguments,1));
}
However since my functions are in a object I was wondering if I could make a new array dynamically?
var func = {'find':find}, func_new={}; //this is just an example I don't have this part in my code
for(var attr in func)
func_new[attr] = Function('return '+attr+'.apply(arguments[0],Array.prototype.slice.call(arguments,1));');

I have a task to create tables dynamically, using the javascript DOM.
The current method uses a 1px x 1px IFRAME to loop through some data
generation stuff, and then call JS functions in the parent window to
generate the tables.
The basic idea is to add a table tag, with a thead and tbody, on the
main parent page, that has display:none set. This then becomes
display:block when there are rows to show. The rows themselves are
added directly to the visible tbody element using appendChild(). When
the results need to be refreshed, the tbody elements are removed, and
then added again.
This works well in most browsers, including Opera. However, Mac IE
always freezes when trying to generate the table, even for the first
time.
I have several different versions, and they all generate the same
issue. The tables I am creating are quite complex: multiple cells,
colspans, images, nested tables, roll over colours, styles etc. At
first, I believed it was an issue with creating images dynamically,
however it now seems that is not the case.
I have also tried creating the table and tbody tags using the DOM and
appending them to a div, but with no luck. I have also tried creating
the tables using a hidden object and then copying the innerHTML / nodes
across to the visible one. The various versions I have cover most
bases:
* using innerHTML to add content to the cells
* using the javascript DOM to create all elements and append them
* using a mixture of the both
If anybody has any feedback or suggestions then it would be really
appreciated, particularly related to the following:
* From your experience, is this realistically possible?
* Is the problem I'm experiencing related to the complexity or size
of the table I am trying to generate? If the table is simple text only,
with 2 or 3 columns and rows, then it does work.
* What is the best method to dynamically create tables and cell
content across browsers, and in Mac IE?
* Is the problem image related? Does anyone have experience of
creating images dynamically in tables in Mac IE? Do you use "new
image()" or createElement()? (using the small table sample, this was
possible using both methods, and also innerHTML on a cell).

I'm dynamically creating a table. I create the <tr>s with five <td>s. I then remove the third <td> and would like to add the cell variable where I removed the td. The creation of the table works, the removal of the td works, now how do I add the cell var where I removed the td? Example here: [URL]
Code JavaScript:
function CreateTable() {
var array = ["one", "two", "three", "four", "five", "six", "seven", "eight", "one", "one", "three", "seven"];
var listItems = "";
var tbody = $('.tbody');
var cell = $('<td>', {
className: 'open',
html: 'Open'
});
$.each(array, function(index, val) {
var row = jQuery('<tr></tr>')
.append('<td>' + index + ' - ' + val + '</td><td> open </td><td> open </td><td> open </td><td> open </td>');
$('td:eq(2)', row).css('background-color', '#eee');
$('td:eq(2)', row).remove();
row = row.add(cell);
row.appendTo(tbody);
});
}

I have a form that allows for dynamic field creation. Basically, you click the + button, and an addition row of fields (2 text fields) are created. The area that is dynamically created is wrapped by a <div id>, within which is, and this might be bad practice so please feel free to mock me , another few nested div id's. It looks something like this:
Code:
Each time you hit the +, it creates a new div id beneath the "Adds" id.
What I'd like to do is see the values of the id's "row_fqdn" and "row_ip". Is there a quick way to access the values of nested id's?
I found a workaround but it seems pretty messy and drawn out, something like this:
Code:
I'm looking for a way to do something like this:

A while back, I an working on dynamic form creation. I wanted a user to be able to enter into a text field how many designs he or she would like, then, based on that number, be provided with a pair of text boxes that asked 1) name of design 2) quantity of that particular design. I received this cool way of doing it by user thraddash:
<head>
<script type="text/javascript">
function BuildFormFields($amount){
var
$container = document.getElementById('FormFields'),
$item, $field, $i;
$container.innerHTML = '';
for ($i = 0; $i < $amount; $i++) {
$item = document.createElement('div');
$item.style.margin = '3px';
$field = document.createElement('span');
$field.innerHTML = 'Name of Design';
$field.style.marginRight = '10px';
$item.appendChild($field); .....
As a followup, I wonder how to control in a table where each of these text boxes will appear.

I have a large table in html created dynamically. This table can grow
to several hundred rows or more. I have the ability to hide or display
individual rows (using row.style.display = "none") and this works well
in both IE and Firefox.
I would also like to do the same with columns as well. I did some
research and col and colgroup nodes are not supported fully in both
browsers. Also, doing "visibility: hidden" and sometimes "display:
none" don't work correctly. The only solution I know to work would be
to go through each row and set the particular cells in the column using
'td.style.display = "none"'. With that many rows, this is not
efficient.
I do have each cell in the column set up with classes. Its easy in
Javascript to set the style of each cell in the DOM. However, I was
wondering if there is a way to set the style of the class itself? For
example, I have the following class defined in CSS:
.columna { display: none; }
Using Javascript, is there a way to change the value of the style of
the class without having to iterate through each row and cell?
Unfortunately I need to support both IE and Firefox, and for
supportability, I would prefer one solution that works on both OS's (I
already have tons of browser dependant code as it is).

I'm looking for a way to do:
function resetBorder(theObj) {
theObj.style.border = theObj.class.border;
}
But it doesn't seem to be as simple as that, I'd like a cross-browser solution, but will settle for IE.

I am trying to work out how to access unrecognised CSS properties within stylesheets from JavaScript.
Say I have a stylesheet containing the following:
p {border-radius: 20px;}
Now. The CSS3 "border-radius" property is not recognised by any browsers at the moment. In Internet Explorer I can still access the property as follows:
alert(document.styleSheets[0].rules[0].style['border-radius']); // Alerts "20px"
However, Gecko and V8 don't seem to include the rule in their JavaScript engines at all:
alert(document.styleSheets[0].cssRules[0].cssText); // Alerts "p { }"
Does anyone know of any way to access unrecognised rules in these engines? Or even better if there are any scripts or plugins available anywhere that will do this for me?

I'm trying to allow the user to change the stylesheet of my website. I can change the stylesheet on a page by page basis (eg. from red style to blue style) but once the user navigates to a different page the stylesheet resets back to the original setting.
For example, when the user visits the site first its set to the red style, they can change it to blue but when they navigate to another page the style goes back to red again where as I want the style to stick across pages. Does anybody know how I can sort this out?

On the web application that I am working on, we have a "Print Preview" javascript function which opens a new window and displays some html. In our solution, there is some javascript code that loops through the CSS on the page and renders it onto the child window. I ran into an issue that the CSS it generated was wrong, and I traced it to the .cssText property (only available in IE) of the items returned by document.stylesheets.item(i)

I know that it is possible to create map via javascript, which has some spots used like links.
I have 3 images:
background, house and man.
Also 3 php variables:
$man = 'yes';
$background = 'yes';
$house = 'no';
What I need is to make javascript map which would show background(yes) and man (yes). House must be invisible, because I have NO.
The problem, that man must appear to 21px width 100px height and be active as a link.
If you haven't understood what I want - ask.
Now I will try to explain this with example.
You have a map with countries. But map is like image and you can't do anything. If variable with country gets value "yes" - the country become active on the map and you can push on it.

I'm working on a script for Hulu that will present the user with some options, then automatically sort their queue depending on those options (a blessing for someone like me with 450+ entries). The sequence is as such:Read and store all entry rowsPresent user with a form to assign shows to categoriesPresent user with a form to assign weights to categories (so something can show up more or less often in a "block") as well as options for how to sort entriesSort previous row listings based on user inputDecide the order of shows and change the values of their respective "Order" boxesI've gotten it to work up until this last part. I'm creating the dialogue boxes using proper DOM input (at least, I believe so), but for some reason I can't use getElementById() or getElementsByName(). I can use getElementsByClassName() and getElementsByTagName(). When trying to use the first two, I'm just told that it isn't a function.
Here's the code section itself, the problem line is Line 3:
Javascript Code:
This is inside an onclick event; finalBox is declared outside of that handler. I'm able to use finalBox.getElementsByClassName in the same function about 20 lines up. For reference, here's where I create the elements I'm trying to find:
Javascript Code:
CustRow is a function that helps me shorten the code of adding a cell to a row (with addCell()); it creates a row element and attaches it to the given table element.
That first piece of code is the only place where I use getElementById. My main thought is that I'm doing the ID wrong and, for some reason, it's not registering with the DOM (though that doesn't explain why getElementById() still fails instead of returning null/undefined). Also, while I hope to eventually make this a FireFox add-on, I'm executing all of this through the FireBug console, so I don't know if that would affect it or not.
Any insights? I can change it to use getElementsByClassName (and it appears to work), but this is really frustrating me and I'd prefer not to use a messy work-around. (Actually, getElementsByName would be best, but I thought that getElementById would at least work.)

I need help putting together a script that will take all standard text on a page and translate it to another language (spanish or german).
So if I post this script on my blog at any given time (in the comment section) it will change the language for all viewers. Where do I start? Will this work on both FF and IE6/7?

I am getting a string with the value of the clicked button from an array and some other select field values that are listed in the same set of mysql results as the clicked button.At the end of the script the page is redirected to in the script mentioned page with following string:process.php?value=1&bs=2&ad=3&ns=4&wt=5&in=6
Is it possible to make locationstring variable global and in a single line in order to be able to use the full string in other scripts or is there another solution.
