Examples

The following example demonstrates FormField.setDescriptiveText in a practical document-editing workflow. It sets the form field's descriptive text. An empty string or null can be used to delete a previously set text.

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

TXTextControl.textParts.getMainText(function(mainText) {
    const formFields = mainText.formFields;
    formFields.getItem(function(formField) {
        if (!formField) {
            console.warn("No form field is available at the current input position.");
            return;
        }
    
        formField.setDescriptiveText(
            "InvoiceNumber",
            function() {
                console.log("set descriptive text completed.");
            },
            onTxError
        );
    }, onTxError);
}, onTxError);
