Baidu Editor: how to get the cursor position and nodes in Different frames

VaR range = editor. selection. getrange ();
VaR TD = domutils. findparentbytagname (range. startcontainer, 'td ', true );

When we console. log (domutils), you can see many domutils methods in the console. These methods are used to operate nodes. As the name suggests, findparentbytagname () obtains nodes, when our cursor is at the content of the editor, and we want to get the ID and attributes of the outer node of the corresponding content, we need to get the nodes in Different frames through domutils.

The corresponding parent node can be viewed in the Dom and queried in sequence to obtain the desired attribute value, which can be displayed in the pop-up layer of the plug-in button.
