The delete() method removes a record from the grid either by index or relative record number.
Parameter
- Index (optional) - Zero-based index of the record to delete. If omitted and a relative record number field is associated with the grid, then the relative record number is used. Unlike an index, where the first record is identified by 0, a relative record number is 1-based; therefore, the first record is identified by relative record number 1.
Example
pjs.defineDisplay("display.json"); // assume display.json defines mygrid with fields named "product" and "description"
display.mygrid.addRecords([
{ product: 1, description: "ITEM ONE" },
{ product: 2, description: "ITEM TWO" },
{ product: 3, description: "ITEM THREE" }
]);
display.mygrid.delete(0);
console.log(display.mygrid.getRecords());
// The line above will log the following output:
// [ { product: 2, description: "ITEM TWO" },
// { product: 3, description: "ITEM THREE" } ]
