Cannot get error count in CodeMirror editor

Is there any way to access the number of errors in code mirror editor. Is it have something to do with lint ?

I created an instance using 

var editor = wp.codeEditor.initialize($('#my_textarea'), my_var.cm_settings);

I can take the value using 

editor.codemirror.getValue();

But this returns the value in editor including the code with error. Is there any function or option to get count of errors ?

Solution

  • You can grab your editors wrapper and count how many errors there are by .length.

    Find the errors by their class name .CodeMirror-lint-marker-error

    var editor = wp.codeEditor.initialize($('#my_textarea'), my_var.cm_settings);
var errors = codeEditor.find('.CodeMirror-lint-marker-error');
console.log(errors.length);

    Or, use editor.state.lint.marked to receive an array of the errors.

    var editor = wp.codeEditor.initialize($('#my_textarea'), my_var.cm_settings);   
var error_array = editor.state.lint.marked;
console.log(error_array.length);
