새 탭 항목 논리적 아이디어

왼쪽 탐색을 클릭하면 데이터(url, id . .. 문제

layui-tree 노드를 클릭하면 현재 노드의 HTML 객체가 아닌 현재 노드 데이터만 반환됩니다

Solution

#🎜🎜 #트리.js 소스 코드 변경

e.children("a").on("click",
                    function(e) {
                        layui.stope(e),
                            i.click(o,this)
                    })
i.click(o)改为 i.click(o,this)
