By default these include options like \"Sort ascending/descending\" and \"Facet by this\", but plugins can return additional actions to be included in this menu. \n The method will be called with a columnDetails object with the following keys: \n \n \n columnName - string \n \n The name of the column \n \n \n \n columnNotNull - boolean \n \n True if the column is defined as NOT NULL \n \n \n \n columnType - string \n \n The SQLite data type of the column \n \n \n \n isPk - boolean \n \n True if the column is part of the primary key \n \n \n \n It should return a JavaScript array of objects each with a label and onClick property: \n \n \n label - string \n \n The human-readable label for the action \n \n \n \n onClick(evt) - function \n \n A function that will be called when the action is clicked \n \n \n \n The evt object passed to the onClick is the standard browser event object that triggered the click. \n This example plugin adds two menu items - one to copy the column name to the clipboard and another that displays the column metadata in an alert() window: \n document.addEventListener('datasette_init', function(ev) {\n ev.detail.registerPlugin('column-name-plugin', {\n version: 0.1,\n makeColumnActions: (columnDetails) => {\n return [\n {\n label: 'Copy column to clipboard',\n onClick: async (evt) => {\n await navigator.clipboard.writeText(columnDetails.columnName)\n }\n },\n {\n label: 'Alert column metadata',\n onClick: () => alert(JSON.stringify(columnDetails, null, 2))\n }\n ];\n }\n });\n});", "breadcrumbs": "[\"JavaScript plugins\", \"JavaScript plugin objects\"]", "references": "[]"}
