I am not able to see the style of the nodes and the lines between the nodes and not able to see tree from top to bottom (means only horizontal rendering).
the style opened on the internet explorer only , i need to open it on the other browsers
Please help me get it.

Hi,
Firstly, thanks for posting this excellent piece of code. It has really helped me a lot. One thing I was trying to do was provide an option to save an image of the tree as a jpg or png for printing or embedding in a presentation etc.
I did some research on the html canvas element and discovered some options for saving it to an image. However when I do, the outline of the tree is rendered but the node content (descritpion) is not.
Here's the code I am using to save the tree to an image element on the page.
var canvas = document.getElementById("ECOTreecanvas");<br />
var context = canvas.getContext("2d");<br />
var img = canvas.toDataURL("image/png");<br />
jQuery("#img").attr("src",img);<br />
And below is a modified version of sample1.htm which will demonstrate what I am seeing.
Does anyone have any suggestions on how to work around this ?
thanks,
Barry.

I would also like to save the generated tree as an image.
Has anybody had any success with this? Any suggestions?

UPDATE: There's a tool (for Macs) called Paparazzi! that can capture and output an image of your trees.
You can find it at: http://derailer.org/paparazzi/

I have met the problem which some nodes will be outside of bundaries. Could anyone kindly send me the lastest version of this javascript? Thanks in advance. Email me.

I have found a link in Code Project http://www.codeproject.com/KB/scripting/graphic_javascript_tree.aspx posted by Emilio CL.
I have used the Walker's algorithm shown in the Figure 4. in the article.
I have used it to show the tree of member's sub-members of a binary MLM system. the nodes show members' ID and Name. When I developed the site in my machine it worked fine but when I published it in a IIS server and tried to show tree in my machine it shows fine but in many machine it does not show node content.
What is the problem? Are there any configuration problem in browsers to show node contents?

Hi
First let me say how great this project is, very useful.
I've created a sharepoint page which generates a company organisation chart from a sharepoint list which includes vacancies, it has images and hover over tooltips for contact details.
I have added MS Communicator status which is displayed next to the person's name in the node by adding the following code to the display variable of the node. -
this works perfectly (where the id and email addresses are unique for each node).
The only small problem is when you expand or collapse nodes all the status indicators revert to grey (offline), but if you click them they show the correct status, just the unclicked one stays grey. If someone then updates their status in communicator the status indicator on their node updates correctly.
It seems to be basically a refresh issue when expanding and contracting nodes and I wondered if anyone has had this issue and can offer a resolution.
Many thanks

Please help... how to create organisation chart that supports the rendering of assistants, it's not sub ordinat.

I was looking for something just like it to build into a genealogical application I'm writing!
One note on using it in IE9 (Beta). Seems the advanced sample have some issues with expanding/collapsing nodes when the selection mode is anything other than none. It's a trivial issue for me as I won't be using it that way but others might complain.
[Update]
Using the 'new version' seems to break IE9 (Beta) completely. It does not render anything at all. Guess I'll be using the old version then.

Hi,
The examples seem to fail when I add the following markup:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
When I say fail, I mean the labels do not appear on the nodes. They seem to be rendering in the bottom left corner of the page.
I am using Firefox 3.6.10 for Windows.
Any solutions?
Thanks
Update:
Kevin Dorff's version (posted below) seems to fix the problem (at the cost of requiring jquery).

I can't drow tree into <td>, or anything else.
|
|
|

You put a link in the menu cam i put a javascript code or a php code in the inside the node? If yes can you give a simple exemple.

I've been playing with this for the last few days (based on the 1.5 codebase). I've made a few changes which I don't necessary expect will be adopted into the "next" release, but I thought I'd share them with the group. This now REQUIRES jQuery. If you were relying on VML or HTML, sorry the code I am submitting ONLY supports Canvas (use "excanvas" for IE).
The rough outline of my changes:
* Requires jQuery (tested with 1.4.2)
* Requires excanvas (tested with r3, assuming you want to support Internet Explorer)
* Now that you can use Canvas in IE (with excanvas), Firefox, Chrome, Safari, this code ONLY supports rendering to Canvas (removed VML). It is possible this version won't work properly with old browsers, as it has not been extensively tested.
* When adding a node, if you specify a width or height of -1 it will "measure" the text and size the box and size it accordingly
* Size the div surrounding the canvas so it fit the constraints of the visible graph and hide the overflow
* Ability to specify the radius of the node corners via config.nodeRadius
* Reformatted code (braces and such).
Suggestions are welcome.
