要实现a-tree的展开和收起功能,可以通过修改样式和操作相关的DOM元素来实现。根据引用中提供的解决方法,可以通过添加以下CSS样式来实现点击title文字展开/收起的效果:
.ant-select-tree-switcher_open::before, .ant-select-tree-switcher_close::before {
content: '';
position: absolute;
right: -200px;
top: 0;
left: 0;
bottom: 0;
}
.ant-select-tree-switcher_close:hover ~ .ant-select-tree-node-content-wrapper-close {
background-color: #e6f7ff;
transition: background-color 0.3s ease;
}
.ant-select-tree-switcher_open:hover ~ .ant-select-tree-node-content-wrapper {
background-color: #e6f7ff;
transition: background-color 0.3s ease;
}
如果需要深度选择,可以在选择器前添加/deep/,如引用中所示。这样可以确保样式可以应用于深层级的元素。
此外,根据引用中提供的信息,可以使用this.$refs.tree.store来获取a-tree的实例,并操作其中的数据。expanded字段可以控制节点的展开和收起功能。
综上所述,您可以通过修改样式和操作this.$refs.tree.store的数据来实现a-tree的展开和收起功能。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
