display.grid.delete()

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" } ]
