Renaming a tree node dynamically outside of contex

问题:

I use the code below to successfully create a new tree node in jstree outside of contextmenu. My question is how can you dynamically RENAME the text in a tree node in a similar manner outside of the contextmenu? Is there a .jstree("rename" ....) function that can be called to accomplish this? Much appreciated!

$("#RequirementsTree").jstree("create", null, "last", {"data" : "new_node_text",
                  "state" : "open",
                  "attr" :  { "id" : "new_node_id", "name" : "requirement" }, 
 });

I've tried the following:

        .bind("select_node.jstree", function(event, data) {
            ReqNode = data.rslt;

 $("#RequirementsTree").rename_node(ReqNode, "test");

That didn't work, however. Is there something I'm doing wrong?

This should work for you:

$("#demo1").jstree('set_text', [node , text] );
$("#demo1").jstree('rename_node', [node , text] );

I'm using jsTree 1.0-rc3 version. The syntax below worked for me:

 $('#companyFields_tree').jstree('rename_node', '#0', 'testNewName' );

The below suggestion by Mortalus didn't work for me. Although it's my preference to stay within the confines of jstree specific code, I came up with a sort of jquery hack to get around the built-in "rename_node" and "set_text" methods since they weren't working for me. I thought I'd post my answer here in case others have the same issue:

   $(Node).find("a").text("the_new_text_for_the_node_you_want_to_rename");

This works for me. It basically grabs the anchor element below the li and sets the text for it.

Shortly, by default jsTree prevents any changes in his tree, so you have to enable that:

$('#YourJSTree').jstree({ core: { check_callback: 'true' }, [...]

The following sentence works:
$("#demo1").jstree('set_text', node , text);
