jsTree - Get the selected node on loaded.jstree event
提问by Yair Nevet
How can I get the selected node on the loaded.jstree event?
如何在loaded.jstree 事件上获取选定节点？
what should I do in the event handler:
我应该在事件处理程序中做什么：
$('#Tree').bind('loaded.jstree', function(event, data){//TODO: How to get the selected node here?}).jstree();
By the way, I found out that the event data arg object contains a function called get_selected() but couldn't get anything from it.
顺便说一下，我发现事件数据 arg 对象包含一个名为 get_selected() 的函数，但无法从中获取任何信息。
My purpose is to redirect the client to the current selected node (by 'url' attribute).
我的目的是将客户端重定向到当前选定的节点（通过 'url' 属性）。
Thanks in advance
提前致谢

Seems according to the documentation of the demo here :
似乎根据此处的演示文档：
you can do :
你可以做 ：
.one("reselect.jstree", function (event, data) { });
or
或者
.bind("select_node.jstree", function (event, data) {
// `data.rslt.obj` is the jquery extended node that was clicked
alert(data.rslt.obj.attr("id"));
})
Read carefully the documentation as :
仔细阅读文档如下：
one is used, this is because if
refreshis called those events are triggered
一个被使用，这是因为如果
refresh被调用，那些事件被触发
// 1) if using the UI plugin bind to select_node
.bind("select_node.jstree", function (event, data) {
// `data.rslt.obj` is the jquery extended node that was clicked
alert(data.rslt.obj.attr("id"));
})
// 2) if not using the UI plugin - the Anchor tags work as expected
// so if the anchor has a HREF attirbute - the page will be changed
// you can actually prevent the default, etc (normal jquery usage)
.delegate("a", "click", function (event, data) { event.preventDefault(); })
For the last event delegate, instead of writing event.preventDefault();, you can make your redirection correctly if you're not using the UI plugin, and write : window.location = $(this).attr('href');
对于最后一个事件delegate，event.preventDefault();如果您不使用 UI 插件，您可以正确地进行重定向，而不是编写：window.location = $(this).attr('href');

you can select current node by :
您可以通过以下方式选择当前节点：
$('#' + data.node.id)
Code becomes:
代码变为：
$('#Tree').bind('loaded.jstree', function(event, data){
console.log($('#' + data.node.id)); //This is current node, see on console
}).jstree();
