需求,右击树节点,出现编辑和删除的提示框
1:在setting 配置里面,给callback设置,右击事件onRightClick:
2:写一个函数onRightClick
function onRightClick(event, treeId, treeNode) { }
3:禁用默认鼠标右击事件
document.oncontextmenu = function(){ return false; }
4:父节点不需要点击事件,父节点为1,如果节点为1 的时候,不执行下一步
if (treeNode.id == "1") { return; }
以上步骤,组成右击事件以下代码:
//右击事件 function onRightClick(event, treeId, treeNode) { document.oncontextmenu = function(){ return false; } //alert(1) if (treeNode.id == "1") { return; } if (treeNode) { zTreeObj.selectNode(treeNode); showContextMenu(treeNode.organId,treeNode.leaf); /*showContextMenu(treeNode.organId,treeNode.leaf, event.clientX -10, event.clientY -10);*/ } }
众所周知,在PC端,我们通常用event.clienX或者event.clientY来获取手指的坐标,注释部分的代码控制提示框的位置。
5:触发事件之后,出现提示框
jsp代码:
<div class="dropdown open" id="treeContextMenu" style="display: none;position: absolute"> <ul class="dropdown-menu"> <li><a href="javascript:;" id="toUpdateBtn">编辑</a></li> <li><a href="#" id="deleteBtn" data-target="#confirmDialog" data-toggle="modal">删除</a></li> </ul> </div>
js代码
function showContextMenu(type,leaf, x, y) { if (type == -1) { $(".dropdown-menu").find("li:not(:first)").hide(); } else if(leaf){ $(".dropdown-menu").find("li:first").hide(); }else{ $(".dropdown-menu").find("li").show(); } $("#treeContextMenu").css({"top": y + "px", "left": x + "px"}).show(); $("body").on("mousedown", onBodyMouseDown); }
6:提示框的一些处理
function hideContextMenu() { $("#treeContextMenu").hide(); $("body").off("mousedown", onBodyMouseDown); } function onBodyMouseDown(event) { if (!(event.target.id == "treeContextMenu" || $(event.target).parents("#treeContextMenu").length > 0)) { hideContextMenu(); } }
