Now this code works on ios safari 4.2 and later but i can't get it to work on ios safari 4.1. On 4.1 it displays the canvas but will not draw the image. The debug console shows no errors. Is there anyway to get it to work, or is 4.2 the cut off point for even the most basic canvas operations?

How to use Javascript to draw a rectangle when the user drags the mouse across the webpage?
I know the drawing methods but how do we allow the user to be able to draw a rectangle on the webpage?
e.g When the user drags the mouse across the page and releases the mouse button, a rectangle appears.
Well, not really a question but I'm pretty pleased with this JS I wrote I had to create triangles for this project I'm on, but there really isn't much out there in the way of that. Especially for things like mouseover effects.
Give it a go, let me know what you think! The only limitation atm is one side of the triangle MUST be flat, facing NSE or W. It's going to have functionality for specifying any 3 coordinates soon, and dragable capability as well a few more bits.

View 11 Replies View RelatedUsing the jQuery SVG plugin, is it possible to load a large .svg and then only draw certain parts on an as needed basis? For example, if you have an outline of all U.S. states but the user only wants to see a certain state. Taking their input, you draw just those lines that are needed.
If this is possible, please point me in the right direction or provide some example code. I am currently using: $('#fp').svg({loadURL: '../rockwell-working2-merged.svg'}); Which displays the entire svg.

View 6 Replies View Relatedi need something simple without much overhead to read plain text (tab separated, columns & rows of data) .. and with the data i need to generate some charts (plot, bar, etc) better be interactive
since javascript doesn't need webserver like php .... setup is simple .. and can be run on any OS. i think it is my best candidate.
i dont know if javascript has any package to do stuff like this. what about interactive graph/chart? is it possible?
I am new to jQuery and wrote a tool for my job that uses the accordion and tab plugins a lot.
However, I find the ability to only load one draw at a time to be limiting.
I am looking for a plugin that functions exactly like the accordion and processes the HTML in the exact same way, while using the standard UI css that allows for more than one draw to be open at any time. I still want the first draw to be loaded first, and would like a 2nd click on a draw header to collapse the draw.
Anyone care to either assist or help out? I have dabbled, but everything I have tried so far requires css be added to the base html which I do not want.
I want this:
To be handled just like the accordion would handle it, while allowing more than one draw to be open at once.
