Examples

The following example demonstrates DocumentTarget.getNumber in a practical document-editing workflow. It gets the one-based number of the document target in the document.

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

TXTextControl.textParts.getMainText(function(mainText) {
    const documentTargets = mainText.documentTargets;
    documentTargets.getItem(function(documentTarget) {
        if (!documentTarget) {
            console.warn("No document target is available at the current input position.");
            return;
        }
    
        documentTarget.getNumber(
            function(result) {
                console.log("get number result:", result);
            },
            onTxError
        );
    }, onTxError);
}, onTxError);
