效果預(yù)期

手風(fēng)琴展開效果：節(jié)點(diǎn)展開同時(shí)關(guān)閉其他已展開的同級節(jié)點(diǎn)

具體實(shí)現(xiàn)

因?yàn)槭枪?jié)點(diǎn)展開，所以在實(shí)現(xiàn)具體效果的回調(diào)方法在于

callback: {
	onExpand: zTreeOnExpand
}
//鼠標(biāo)點(diǎn)擊
function zTreeOnClick(event, treeId, treeNode){
	//過濾查找同級
    const treeNodes = treeObj.getNodesByFilter(function(node){
        return (node.parentCode == treeNode.parentCode)
    })
    for(var item of treeNodes){
    	if(item.code != treeNode.code){
    		//關(guān)閉同級節(jié)點(diǎn)
    		treeObj.expandNode(item, false, true, false,true);
    	  }
    }
