angularjs之根据某个属性值将json分组

         

angular.forEach(rightOptions.options,function(v,k){    _label = v.group;    var subInsertMenus = {};    if(!rightMenus[_label]){//判断父节点是否存在	  subMenu(v);	  subInsertMenus[v.label] = srm;	  var rm = {			  "label": _label,			  "separator_before":false,			  "separator_after":false,			  "submenu":subInsertMenus	  };	  rightMenus[_label] = rm;    }else{	  subMenu(v);	  rightMenus[_label].submenu[v.label] = srm;    }});
