如何在Codemirror中删除新行上的缩进

Question

In my case, cursor jump through one empty line. How fix this? Thanks in advance.

In Angular 5 + Electron.

html:

   <codemirror
     [config]="{
       lineWrapping: true, 
       autofocus: true, 
       showCursorWhenSelecting: true,
       smartIndent: false
     }"
     (keyup.enter)="removeIndentation()"
     #novelEditor>
   </codemirror>

ts:

import { CodemirrorComponent } from 'ng2-codemirror';
...
@ViewChild('novelEditor') private novelEditor: CodemirrorComponent;
...
  removeIndentation() {
    const cm = this.novelEditor.instance;
    cm.replaceSelection("\n");
  }

Answer 1

I solved it

removeIndentation() {
   const cm = this.novelEditor.instance;
   cm.execCommand('delLineLeft');
}
