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.
In PS you press CTRL+T on new layer. 9 handles appears an then you can stretch/rotate/move that layer. Looking just for that stretch & rotate functionality with dotted/dashed retangle outline. That is, there should be 8 handles on rectangle boundarys and then rectangle should be rotated & stretched via those points. & moved via nineth center point.

View 11 Replies View RelatedI have an application that draws a selection rectangle over a map
image. I can get it to work fine in IE and Opera, but not
Firefox/Netscape.
I've thrown the following small example together to illustrate the
problem - the problem being that FF/NE initially draw my rectangle
before the icon changes immediately to the black no-entry icon. Then,
when I let go of the mouse, the rectangle continues drawing, but it
doesn't stop as the mouseup has already fired of course.
IE was doing the same, but I found the ondragstart/cancelDragDrop
solution to that. I can't find what appears to be a similar solution
for FF/NE.....
I am retrieving titles from a database and then displaying them on screen. However when I display them I must make sure that they fit inside a certain rectangle. If it deosn't fit then i must reduce the font size and recalculate until it fits. The title is in two parts Code:

When setting the tabIndex property for an element, Firefox also displays, like IE, a dotted rectangle around the focussed element. With IE you can set hideFocus=true, which does not work with Firefox.
How do I hide the focus rectangle for Firefox?

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.
Any jQuery plugin that people would recommend for drawing bar charts or general graphs?
View 5 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 1 Replies View RelatedI 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.
