问题描述
我发现这个网站，让你插入和删除从B树项目和直观地显示了B树的样子：
I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like:
我在寻找类似这样的其他网站或程序。本网站不允许你指定的4阶B树（4球和3片），它只是让你有偶数个元素的指定B-树。另外，如果可能的话，我希望能够插入而不是数字字母。
I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even number of elements. Also, if possible, I'd like to be able to insert letters instead of numbers.
我想，我居然发现一个不同的网站，但，这是前一阵子，无法找到它了。
I think I actually found a different site but that was a while ago and can't find it anymore.
推荐答案
我实施了CLRS在JavaScript中描述的B树：的
I implemented the B-tree described in CLRS in JavaScript: http://ysangkok.github.io/js-clrs-btree/btree.html
要上手，preSSINIT这么简单。然后放置在输入字段光标刚插入按钮之前。现在进入一个数字是不是在树和preSS进入。焦点仍然在场上，让您可以快速插入多个条目。如果按删除，这将是操作触发，当你按回车。
To get started, press "init simple". Then place your cursor in the input field just before the insert button. Now enter a number which isn't in the tree and press enter. Focus remains in the field so that you can insert multiple entries quickly. If you push "delete", this will be the action triggered when you push enter.
建议非常欢迎。
