The following example demonstrates InputFormat.getSubscript in a practical document-editing workflow. It gets a value specifying whether text is subscript at the current input position.

function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

TXTextControl.inputFormat.getSubscript(
    function(result) {
        if (result) {
            console.log("get subscript is available.");
        } else {
            console.warn("get subscript is not available in the current document state.");
        }
    },
    onTxError
);
