I am trying to plot a line using the variables that I have derived in this "rectangular to polar" conversion program. I am just new to javascript and to programming generally. But with the help of sample codes here.
I have read that drawing in javascript isn't so easy. Could you give me some hints on how to draw the following variable in polar coordinates. Do I need to use another programming language aside from javascript ?
I need to create a real-time line plot on an html page, without
resorting to java, cgi, or anything server-side or offline. I think
maybe this could be done with javascript, or dhtml, and most likely
macromedia flash - what may be the best choice for a clean and
portable design?
I need to create something similar to this: Purely Pesto - Handmade By Chefs
I have looked here: Google Maps Javascript API V3 Basics - Google Maps JavaScript API V3 - Google Code
I have an img of a map of Europe in a div. I want to plot routes between cities in Europe as dotted lines. The image is scrollable and I want the routes to scroll with the image. So the routes should be attached to the image. Furthermore, when drawing routes outside of the viewable area, the routes should be clipped so they don't show up outside of the image. but when the image is scrolled, the routes should appear.

I am trying to load a jquery chart (Flot) inside the second tab of jQuery tabs. It works fine on the opening tab, but if i bury the chart in any tab, it breaks and throws the js error "Invalid dimensions for plot..."I looked around and the problem might be that because the second tab is hidden at page load, it is breaking something... I dug up a possible jquery fix/plugin called frameReady, which allows for you to load iframes, but I am not sure how to apply it.

how I can enable the second tab to show the chart?

I have a user that insists they have web applications that do this, and wants the one I'm building to do it too...
You have a table on an html form. As the user changes one or more fields in a table row and moves to the next line, the changed row should AUTOMATICALLY be sent back to the server and updated in the database.
If the user moves BACK to a line that's already been changed, and changed a field, a popup should display and ask "if the user really wants to change the field". If so, again, it should AUTOMATICALLY be sent to the server and updated in the database...
Ignoring the horridness of making that many round trips to the server and banging the database for every line, is there a way to AUTOMATICALLY do the equivalent of a submit and post the changed table row back to the php script?
Anyone know how to get Javascript variables into PHP variables or a MySQL database? Full question in the PHP section.

View 1 Replies View RelatedI have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:

i use the following to add a line. how can i delete the last line?
oDiv = document.getElementById("MyDiv");
oDiv.innerHTML = oDiv.innerHTML + string;
in ASP i can finish this line with an asp variable like below
mytext variable would contain a string like
"Pop_up()" <body Onload = <%=mytext%>>
so using ASP i can complete my onload statement.
I need a way to do this using a variable in Javascript.
How can this be done?
i need to delvelop something like "SomeName X". Currently i am doing with DIV(1 DIV for 'SomeName' and 1 DIV for 'X' and finally float-left to another DIV). Since these names(like "Somename1 X",'Somename2 X")are populated in the div container, when it reaches the right end of the container, "X" alone getting wrapped to the next line. But it has to be along with 'SomeName' always. As other forums says, I tried with table but it didn't work since the final div container is fixed and i get multiple names with variant length. I tried clear: both, float left - it too didn't work. I have seen like the one in facebook - compose page.

This works without <a href>:
Code:

today = Stamp.getDate();
msg[1] = "Tip 1";
This doesn't:
Code:
var msg = new Array();

Is there a small graphics library that I can use? All I need to do is
draw a line of a nominated thickness and colour between two specified
points and to, at some later time, "delete" the line?
I've found a few offerings but either they weren't multi-browser
compatible or they were too big for me to consider (20K instead of 2 or 3K).
I can get the escape character " " or document.writeln to give me a new line.
Or for that matter any of the form feed " f " or carriage return " " to work either.
I can get the escape character " " " I'm using XP home with SP2 with IE6 all my security setting set to Prompt so if that was an issue then at least I should get a prompt for allowing the

View 1 Replies View RelatedSay I have some CSS, which is several hundred lines long, with the
contents in this format:
..foo {
blah
color:#000;
blah
}
..bar {

color:#FFF;

where the selectors and their opening braces, their closing braces, and
declarations are each on their own lines (always), how can I replace a
specific declaration (line) given a unique selector and a declaration
property. For example, if I wanted the 'color' declaration property line
in the 'bar' class changed.
At the moment I'm iterating through the CSS one line at a time looking
for the selector and then looking for the declaration property (before I
hit the closing brace).
I have the following function:
function showValues() {
