Cutting text from a readonly input should not remove text

[kalmancsaba]

Cutting text (Ctrl+X) from an ordinary readonly input element does not remove the text.

With Cleave however, selecting the entire content of a readonly input element and pressing Ctrl+X removes the text.

Please check the readonly property of the element before calling this.onInput(''); in function onCut:

onCut: function (e) {
    if (!Cleave.Util.checkFullSelection(this.element.value)) return;
    this.copyClipboardData(e);
    if (!this.element.readonly) {
        this.onInput('');
    }
},
