vue+iview使用树形控件
1.开发环境 vue+iview
2.电脑系统 windows10专业版
3.在使用 vue+iview开发的过程中,我们经常会使用 iview的树形控件,在这里我就简单的做一个分享,希望对你有所帮助!
4.在template中添加如下代码:
<Scroll style="width: 100%" height="760">
<Tree
@on-select-change="chentreelick"
:data="treedata"
expand-node
></Tree>
</Scroll>
5.在 return 中添加如下代码:
treedata: [
{
title: "parent 1",
chenshow: false,
expand: true,
children: [
{
title: "parent 1-1",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-1-1",
chenshow: true,
},
{
title: "leaf 1-1-2",
chenshow: true,
selected: true,
},
],
},
{
title: "parent 1-2",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-2-1",
chenshow: true,
},
{
title: "leaf 1-2-1",
chenshow: true,
},
],
},
{
title: "parent 1-3",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-3-1",
chenshow: true,
},
{
title: "leaf 1-3-1",
chenshow: true,
},
],
},
{
title: "parent 1-4",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-4-1",
chenshow: true,
},
{
title: "leaf 1-4-1",
chenshow: true,
},
],
},
{
title: "parent 1-5",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-5-1",
chenshow: true,
},
{
title: "leaf 1-5-1",
chenshow: true,
},
],
},
{
title: "parent 1-6",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-6-1",
chenshow: true,
},
{
title: "leaf 1-6-1",
chenshow: true,
},
],
},
{
title: "parent 1-7",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-7-1",
chenshow: true,
},
{
title: "leaf 1-7-1",
chenshow: true,
},
],
},
{
title: "parent 1-8",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-8-1",
chenshow: true,
},
{
title: "leaf 1-8-1",
chenshow: true,
},
],
},
{
title: "parent 1-9",
chenshow: false,
expand: true,
children: [
{
title: "leaf 1-9-1",
chenshow: true,
},
{
title: "leaf 1-9-1",
chenshow: true,
},
],
},
],
},
],
5-1.注意 这个 return中绑定的数据,可以参考 iview官方文档,地址如下:
https://www.iviewui.com/components/tree
6.在 methods中添加如下代码:
chentreelick(data) {
console.log(data);
console.log("点击了");
console.log(data[0].chenshow);
},
//注意:参数 data,在点击的时候可以获取到后台的数据,这个数据是来自后台的,在实际开发中,我们可以 利用 data,把后台需要的id传给 后台
