获取 Google Blockly Block by Id？

Question

我想查询 DOM 以通过 ID 获取块。目前我必须通过 class 名称查找所有元素，并手动提取正确的索引，这是不可持续的。

如何给一个块一个唯一的ID？

谢谢

所有块都已经有一个id（api docs). However, a Block object isn't a DOM object so you won't find it by using document.getElementById(..). Instead you'll use Workspace.getBlockById(..). Your workspace is usually Blockly.mainWorkspace
