How can i disable first few number of lines in editor, and also how can i update codemirror in this state.
I tried this to disable few lines
var readOnlyLines = [0,1,2];
editor.on('beforeChange',function(cm,change) {
if ( ~readOnlyLines.indexOf(change.from.line) ) {
change.cancel();
}});
After executing above code, results in disabling of lines “1”, “2”, “3”.
But now when i try to update codemirror using
editor.setValue(<MY STRING DATA HERE>);
Then it is not updating the data.
How can i make it update after disabling few lines also.
