jsTree AJAX搜索带有一些节点子节点? [英] jsTree AJAX search with some node childs?

问题描述

我尝试在jsTree中实现ajax搜索，但仅在根节点之一内部实现.

I try to implement ajax search in jsTree, but only inside one of root node.

我阅读了文档，发现了有关以下内容的信息:

I read docs, and found some info about:

$ .jstree.defaults.search.ajax

将在请求中添加一个str(即搜索字符串)参数，如果搜索仅限于节点ID，则会添加一个可选的inside参数.

A str (which is the search string) parameter will be added with the request, an optional inside parameter will be added if the search is limited to a node id.

我的SEARCH AJAX配置:

My SEARCH AJAX config:

        "search": {
        // search config
        "show_only_matches": true,
          'ajax': {
            'url': "/ajax/root-nodes"
          }
        },

jsSearch呼叫:

jsSearch call:

$tree.jstree(true).search(searchText);

我还使用子节点的延迟加载.

I also use lazy-loading of subnodes.

有人在做这样的事情吗?

Is anybody do something like this?

推荐答案

在您的通话中，您并没有将搜索限制在特定的节点上:
http:///www.jstree.com/api/#/?q=search%28&f=search%28str%20[,%20skip_async]%29

In your call you are not limiting the search to a particular node:
http://www.jstree.com/api/#/?q=search%28&f=search%28str%20[,%20skip_async]%29

例如，如果您的根节点ID是"root1"，请使用此命令:
$tree.jstree(true).search(searchText, false, true, 'root1');

If for example your root node ID is "root1" use this:
$tree.jstree(true).search(searchText, false, true, 'root1');

一旦调用search函数，将根据您的配置发出AJAX请求.因此，在您的情况下，如果用户搜索"foo"-这将是具有两个参数-str和inside的GET请求:
GET /ajax/root-nodes?str=foo&inside=root1

Once the search function is invoked an AJAX request will be made as per your config. So in your case if the user searched for "foo" - it will be a GET request with two params - str and inside:
GET /ajax/root-nodes?str=foo&inside=root1

您的响应应该是一个JSON数组，其中包含所有需要加载(和打开)的唯一父ID.您可能希望通过执行服务器端搜索，收集每个匹配项的父项，然后将它们组合到一个数组中(仅保留唯一的条目)来构建此数组:
["root1","somenode"]

Your response should be a JSON array, containing all the unique parent IDs that need to be loaded (and opened). You'd probably want to build this array by performing a server-side search, collecting the parents of each match, and then combining them in an array (and leaving only unique entries):
["root1","somenode"]
