suwis-paths 支持全节点渲染，也支持局部节点懒加载，当页面节点数量过大时，可用此方法远程加载节点
示例
```
// 远程加载
lazyLoad(opt) {
// 远程加载
this.$Loading.start()
this.$axios.jsonp.get('/path_item.php', {
...this.params,
subpath: opt.item.subpath,
rank: opt.item.rank,
main_url: opt.item.main_url
}).then(res => {
this.$Loading.finish()
var subitems = res.data.landpage_item || []
opt.resolve(subitems)
})
}
```
