Examples

The following example demonstrates FormFieldCollection.getItem in a practical document-editing workflow. It gets the form field at the current text input position or the form field with the specified id.

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 was returned.");
                return;
            }
            
            console.log("get item result:", formField);
        },
        onTxError,
        25
    );
}, onTxError);
