collapse/open only on click on icon

[kr]

Is it possible for the tree only collaspe/open on the click on icon but not on the node text? If yes, how can we do that? Thanks for the help.

First parameter of node definition will be inserted into <A></A>, which will contain click handler. You can disable this handler like in the following sample.

Alex,

I'd like to make this change in my code - can you tell me where I'm going to find the necessary code to effect this change *permanently*. I am generating my trees dynamically from a database, so I need to make this change at the source.

Thanks,

Bruce

Sure, you can modify source code of the script. But on the next release you will have to apply this patch again.
There is two more places where you can put some code to achieve same effect: 1) you can change your CGI script which generates tree structure and 2) you can (or I can if you prefere) write tiny JavaSctipt function which will walk-and-modify ready tree structure before passing it to COOLjsTree or COOLjsTreePRO.

Thanks Alex, but I now see that my question was poorly presented.

I altered my tree-generating script and achieved what your answer indicated. However, that was not what I wanted. I use the caption element to launch a particular process elsewhere in my page - you previously supplied the code for this.

Is it possible to
1. Retain the live caption but stop its click handler from collapsing the node
and
2. Constrain the click handler that controls the collapsing/opening of the node to just the icon?

Hope I have made this clearer.

Cheers,

Bruce

Yes, now I see.
There are two ways:
1. ['</a><a href="your_own_link.html">Caption</a><a>', null, null],
Since your tree is DB driven this will not be too hard to implement this.
2. Patched version of the script. Sure, I will not publish patch here - plese, send you request along with Ref.No. to jssupport@cooldev.com.

I tried this in my cooljstreePro and it works fine and dandy. However now my bold-selected node no longer bolds. Is there an easy way to do this?


['</a><a href="your_own_link.html">Caption</a><a>', null, null],

You need additional CSS reference. If you CSS class was clsNode, then you should define your nodes like this:

Hi Alex,

Is there any way to do exactly what is discussed here but within the context of frames?

I would want to click on the node's text, not have the tree collapse/exand, and have the page display in a frame other that where the tree is displayed.

As this sat in the back of my mind for a while, I realized that the answer to this is simply to use the 'target attribute of the <a> anchor tag:

['</a><b><a href="your_own_link.html target=your_target_frame">Caption</a></b><a>', null, null],

In this way, the display can be targeted to any frame in the overall frameset.

Alex,

(I hope I won't be answering this myself again after 2 minutes).

After doing all the above suggestions, the node selected (clicked by the user) nolonger shows itself to be highlighted after the node is selected.

In the tree_format, option 21 is 'true'. Adding a .clsNodeSelected class to option 22 does not seem to help either.

I think it is time for you to upgrade to newer version of the Pro - it provides advanced control for event handlers. Ask at jssupport@cooldev.com (don't forget your Ref.No.).

I have finally figured out how to do this, with a bit of help from Alex Kunin and after looking in the tree's js code, the trick is to override the onclick handler for the caption, like this:
