ACE Editor修改自动换号缩进

This is controlled by indentedSoftWrap setting in ace, you can turn it off by running

editor.setOption("indentedSoftWrap", false);

behaviours setting is completely unrelated and controls automatic insertion of closing brackets and tags.

So your code from the above would become

var editor = ace.edit("edittext");
editor.setOptions({
    maxLines: Infinity, // this is going to be very slow on large documents
    useWrapMode: true, // wrap text to view
    indentedSoftWrap: false,
    behavioursEnabled: false, // disable autopairing of brackets and tags
    showLineNumbers: false, // hide the gutter
    theme: "ace/theme/xcode"
});
