How to listen for double-click on jstree?
提问by Alex Reynolds
How would I write a listener for a double-click event on a jstree object? (For example, I'd like to double-click on a tree node and paste its anchor's hrefvalue into an inputfield in a form somewhere.)
我将如何为 jstree 对象上的双击事件编写侦听器？（例如，我想双击一个树节点并将其锚点的href值粘贴到某个input表单中的某个字段中。）

I have used something like this way back a year ago, i don't know if there's any change in the current jstree version :
一年前我用过这样的东西，我不知道当前的 jstree 版本是否有任何变化：
jstree.bind("dblclick.jstree", function (event) {
var node = $(event.target).closest("li");
var data = node.data("jstree");
// Do some action
});
node :Contains the li that is being clicked.
node :包含被点击的 li。
data :Contains the metadata.
data ：包含元数据。

Nirmal's solution works if you click anywhere on the jstree div. I wanted to enable double click only on the nodes themselves and not, for example, on the whitespace to the right. changing the solution a little enabled this:
如果您单击 jstree div 上的任意位置，Nirmal 的解决方案就会起作用。我只想在节点本身上启用双击，而不是在右侧的空白处启用双击。稍微改变解决方案可以实现这一点：
$('#jstree-div a').live('dblclick',function (e) {
var node = $(e.target).closest("li");
var type = node.attr('rel');
var item = node[0].id;
// do stuff...
});
Not sure why the 'rel' and the 'id' attributes are in different places in the resulting node, but it works ;)
不知道为什么 'rel' 和 'id' 属性在结果节点中的不同位置，但它有效;)
