<div class="layui-tabs layui-hide-v" id="demoTabsBeforeChange"> <ul class="layui-tabs-header"> <li lay-id="aaa">Tab1</li> <li lay-id="bbb">Tab2</li> <li lay-id="ccc">Tab3</li> <li lay-id="ddd">Tab4</li> <li lay-id="eee">Tab5</li> <li lay-id="fff">Tab6</li> </ul> <div class="layui-tabs-body"> <div class="layui-tabs-item">Tab Content-1</div> <div class="layui-tabs-item">Tab Content-2</div> <div class="layui-tabs-item">Tab Content-3</div> <div class="layui-tabs-item">Tab Content-4</div> <div class="layui-tabs-item">Tab Content-5</div> <div class="layui-tabs-item">Tab Content-6</div> </div> </div>

本示例演示：切换标签时，弹出确认提示。

<!-- import layui --> <script> layui.use(function() { var tabs = layui.tabs; // 标签实例 ID var DEMO_TABS_ID = 'demoTabsBeforeChange'; // tabs 切换前的事件 tabs.on(`beforeChange(${DEMO_TABS_ID})`, function(data) { console.log('beforeChange', data); // 切换确认提示 layer.confirm(`确定从「当前标签」切换到标签「${this.innerText}」吗？`, function(i) { tabs.change(DEMO_TABS_ID, data.to.index, true); // 强制切换 layer.close(i); // 关闭确认框 }); // 阻止标签默认切换 return false; }); }); </script>
