Double-click event code for adding nodes in jquery. jstree

Jstree is a jquery-based tree plug-in that supports drag-and-drop, copy, delete, shortcut keys, multiple selections, custom node icons, custom right-click menus, and cross-page save statuses, in short, I think it is basically there, and the most commendable thing is that it makes people feel not slow at all.

Jstree has a node selection event, that isCopyCodeThe Code is as follows:. BIND ("select_node.jstree", function (E, data ){
// Alert (data. rslt. obj. ATTR ("ID") + ":" + data. rslt. obj. ATTR ("rel "));
})

In fact, I think it is more like a node click event, because it is triggered every time a node is clicked, regardless of whether the node has been selected.

Recently, a file management task needs to use the double-click event of a node. For example, double-click a node to open the editing page of the node.

Although there is a double-click event in jstree, It is not targeted at nodes, but is triggered in the area where you double-click the tree, such as any place.

The node selection event is the closest to the node double-click event.

Analysis
This. get_container () is the Click Event of the node.Copy codeThe Code is as follows:. Delegate ("A", "click. jstree", $. Proxy (function (event ){
Event. preventdefault ();
This. select_node (event. currenttarget, true, event );
}, This ))

Similarly, I will insert a node double-click event here.Copy codeThe Code is as follows:. Delegate ("A", "dblclick. jstree", $. Proxy (function (event ){
Event. preventdefault ();
This. dblclick_node (event. currenttarget, true, event );
}, This ))

Then, I can implement the dblclick_node method.

Finding the select_node code in Row 3 is complicated. However, "90%" is useless for double-clicking, such as processing multiple choice, multiple choice, and saving the selection result to cookies. Therefore, the implementation of the dblclick_node method is much simpler than that of select_node.Copy codeThe Code is as follows: dblclick_node: function (OBJ, check, e ){
OBJ = This. _ get_node (OBJ );
If (OBJ =-1 |! OBJ |! OBJ. Length) {return false ;}
This. _ callback ({"OBJ": OBJ });
},

OK.

Example
Same as select_nodeCopy codeThe Code is as follows:. BIND ("dblclick_node.jstree", function (E, data ){
// Alert (data. rslt. obj. ATTR ("ID") + ":" + data. rslt. obj. ATTR ("rel "));
})

By the way
Jstree and jquery validate, another plug-in, are difficult to deal with. When they coexist, jstree can also construct trees, but they cannot be expanded like botnets. Mark one here and try to modify it later.
