Ist es eine Antwort auf Ihre Frage? Sie sollten auf den Link "Bearbeiten" unter dem Text Ihrer Frage klicken, um den Text zu bearbeiten oder der Frage weitere Informationen hinzuzufügen. Sie sollten zusätzlich immer die ** Version ** von jqGrid schreiben, die Sie verwenden (können), und die ** fork ** ([free jqGrid] (https://github.com/free-jqgrid/jqGrid), kommerzielle [Guriddo jqGrid JS] (http://guriddo.net/?page_id=103334) oder ein altes jqGrid in Version <= 4.7) – Oleg

Es ist unklar, wie Sie die Knoten des TreeGrids laden wollen. Der Code enthält kommentierte '" url ":" data.json "' und '" datatype ":" local "," data ": rows' und du verwendest' "treedatatype": "json" '. Wie möchten Sie die Daten laden: von lokalen 'Zeilen' oder vom Server über Ajax-Anfrage, um JSON-Daten zu laden? Wenn "rows" ** full data ** enthält und Sie keine Knoten bei Bedarf laden möchten, sollten Sie in jedes Datenelement die Eigenschaft "loaded: true" einfügen. – Oleg

Für Localdata Typ "Can not Eigenschaft 'rowIndex' von undefined lesen", müssen Sie den localReader Parameter konfigurieren:

localReader: { 
    repeatitems: true, 
    // cell: "", 
    id: "category_id" 
}
