### 基本用法
#### Tag 方式
```vue
<template>
<u-tree-select-new v-model="value" :data-source="load" text-field="title" value-field="title">
</u-tree-select-new>
</template>
<script>
// 模拟后端请求
const mockRequest = (data, timeout = 300) => new Promise((res, rej) => setTimeout(() => res(data), timeout));
export default {
data() {
return {
value: '页面2'
};
},
methods: {
load(params) {
if (!params.node) {
return mockRequest([
{ type: 'app', title: '应用1', childrenField: 'services' },
{ type: 'app', title: '应用2', childrenField: 'services' },
]);
} else if (params.node.type === 'app') {
return mockRequest([
{ type: 'service', title: '服务1', childrenField: 'pages' },
{ type: 'service', title: '服务2', childrenField: 'pages' },
{ type: 'service', title: '服务3', childrenField: 'pages' },
]);
} else if (params.node.type === 'service') {
return mockRequest([
{ type: 'page', title: '页面1', isLeaf: true, childrenField: 'children' },
{ type: 'page', title: '页面2', isLeaf: true, childrenField: 'children' },
]);
}
},
},
}
</script>
```
#### Tag 方式
``` html
<u-tree-select-new value="节点 1" valueField="text" textField="text1">
<u-tree-view-node-new text="节点 1" :node="{text1: '节点 2'}">
<u-tree-view-node-new text="节点 1.1" :node="{text1: '节点 1.1'}"></u-tree-view-node-new>
<u-tree-view-node-new text="节点 1.2" :node="{text1: '节点 1.2'}">

</u-tree-view-node-new>
</u-tree-select-new>
```

#### 一维Data
``` html { width: 30% }
<u-tree-select-new :data-source="[{id: 1, name: '节点1', pid: null}, {id: 2, name: '节点2', pid: 1}, {id: 3, name: '节点3', pid: null}, {id: 4, name: '节点4', pid: null}, {id: 5, name: '节点5', pid: 1}, {id: 6, name: '节点6', pid: 2}]"
parent-field="pid"
value-field="id"
children-field="children"
text-field="name"
></u-tree-select-new>
```
#### 动态插槽数据
``` html { width: 70% }
<u-tree-select-new valueField="value" textField="text" childrenField="children" :data-source="[
{ text: '节点 1',value: '1', children: [
{ text: '节点 1.1', value: '1.1' },

{ text: '节点 1.2.2', value: '1.2.2' },
] },
{ text: '节点 1.3', value: '1.3' },
{ text: '节点 1.4', value: '1.4', },
] },
{ text: '节点 2', value: '2' },
{ text: '节点 3', value: '3',children: [
{ text: '节点 3.1', value: '3.1'},
{ text: '节点 3.2', value: '3.2'},
] },
]">
<template #item="scope">
<u-text>{{ scope.item.text }} - {{ scope.item.value}}</u-text>
</template>
<u-tree-view-node-new ref="tree_view_node_new11" text="选项一" value="jing1">

</u-tree-view-node-new>
</u-tree-select-new>
```
#### 动静结合选项回填
``` html { width: 70% }
<u-tree-select-new valueField="data.id" textField="data.deptname" parentField="data.parentid"
:data-source="[ { 'data': { 'id': 1, 'deptname': '一级部门a', 'parentid': 0, 'name': '小明' } }, { 'data': { 'id': 2, 'deptname': '一级部门b', 'parentid': 11, 'name': 'xiaoming' } }, { 'data': { 'id': 99, 'deptname': '一级部门c', 'parentid': 0, 'name': 'xiaoming' } },{ 'data': { 'id': 3, 'deptname': '二级部门a', 'parentid': 1, 'name': '小明2' } }, { 'data': { 'id': 4, 'deptname': '三级部门a', 'parentid': 3, 'name': '小明3' } } ]"
