CodeMirror. An easy way to replace text?

I use CodeMirror(5.58.2) for editing text.

new_cm = CodeMirror.fromTextArea(textarea_obj, param);

But in the textarea, I can easy replace text, just do this obj.value = obj.value.replace( /123/g, '3210'); What can I do smth like that in CodeMirror? Without any interface requests for user. Just a simple "Make Replace" button and code with a regexp pattern.

Solution

  • Here is an example ...

    // start the editor instance  
const new_cm = CodeMirror.fromTextArea(textarea_obj, param);

// get the entire editor text from CodeMirror editor  
let text = new_cm.getValue();

// edit the text, for example  
text = text.replace(/abc/g, '');

// set the text back to the editor  
new_cm.setValue(text);
