接前两篇博文，最终方案终于定了，也把之前做的编辑器模式给否决了，原因是系统中有老的文档需要平替，因此就不能通过编辑器这种模式了，太麻烦了。
最终方案：线下手动pandoc word转markdown，然后将文档保存到前端（图片也在对应路径下）页面上菜单绑定文档，文档中自动生成目录；

issue

v-md-editor群里大佬提供了生成自定义锚点（目录）的方式，但是是数组平铺的，根据级别然后展示的时候通过距离形成视觉上的菜单，但是需求模型上是菜单可点击收缩打开方式的，因此，需要调整该数组为树结构，因为本人纯后端，在朋友帮助下，将数组转为了树

解决方法

//0 1 2 3 代表菜单级别
const target = {
	"titles": [
		{"title:": "导读","lineIndex": "1","indent": 0},
		{"title:":"功能范围","lineIndex":"1","indent":1},
		{"title:":"寻求帮助","lineIndex":"1","indent":1},
		{"title:":"业务功能介绍","lineIndex":"1","indent":0},
		{"title:":"1.二级标题","lineIndex":"1","indent":1},
		{"title:":"1.1 三级标题","lineIndex":"1","indent":2},
		{"title:":"1.1.1四级","lineIndex":"1","indent":3},
		{"title:":"1.2 san级","lineIndex":"1","indent":2},
		{"title:":"2.四3级","lineIndex":"1","indent":1},
		{"title:":"2.1四2级","lineIndex":"1","indent":2}
	]
}

function getTree(titles) {
    const res = []
    let treeNodeList = []
    let last = null

    function getParentNode(index) {
        let currentIndex = index - 1
        while (!treeNodeList[currentIndex]) {
            currentIndex--
        }
        return treeNodeList[currentIndex]
    }

    for (let i = 0, l = titles.length; i < l; i++) {
        const item = titles[i]
        if (item.indent == 0) {
            res.push(item)
            treeNodeList = []
        } else {
            // 父节点
            const currentParent = getParentNode(item.indent)
            if (currentParent.children) {
                currentParent.children.push(item)
            } else {
                currentParent.children = [item]
            }
            if (last.indent > item.indent) {
                treeNodeList = treeNodeList.splice(0, item.indent)
            }
        }
        // 把自己放到节点队列中
        treeNodeList[Number(item.indent)] = item
        last = item
    }
    return res
}

console.log(JSON.stringify(getTree(target.titles)))

最终得到的转换后的结构
ps: 用后端逻辑开发前端真的是不好转换，总想着先去定义对象，结果根本没那么需要，强弱类型的开发方式真的太不同了。
