Easyui Tree Method Extension-getlevel (Get node level)

Easyui Tree has not provided this method, has not been used before, so has not much attention, this time to use, and by extension of a method to share to everyone.

$.extend ($.fn.tree.methods, {getlevel:function (jq,target) {var L = $ (target). Parentsuntil ("Ul.tree", "ul"); return l.length+1;}});

Usage:

var node = $ (). Tree ("getselected"); var LV =  $ (). Tree ("Getlevel", node.target);

$ (' #ParentID '). Combotree ({                //Get data URL                  URL: '/handlers/car_brandhandler.ashx?type=tree ',                //Select tree Node trigger event                  onselect:function (node) {                                        var node11 = $ (this). Tree ("getselected");                                       Alert (this). Tree ("Getlevel", Node11.target));}            );
