JavaScript DataCollection - sort Method

sorts data items in a component

sort(rule?: object, config?: object): void;

• rule: object - an object with parameters for sorting. The object has the following attributes:
  • by: string | number - the id of a data field
  • dir: string - the direction of sorting: "asc" or "desc"
  • as: function - a function that specifies the type to sort data as
  • rule: function - optional, a sorting rule; the function must have two parameters and return a number (-1,0,1)
• config: object - defines the parameter of sorting. It may contain one property:
  • smartSorting: boolean - specifies whether a sorting rule should be applied each time after changing the data set

Example

grid.data.sort(
    {
        by:"a",
        dir:"desc",
        as: item => (item.toUpperCase())
    },
    { smartSorting: true }
);

// cancels the applied sorting rules
grid.data.sort();

Related sample: Data. Sorting

note

Calling the method without parameters will discard all applied sorting rules.

To set a custom function for sorting, you need to specify the rule attribute in a passed object. For example:

grid.data.sort({
    rule: (a, b) => a.id > b.id ? 1 : (a.id < b.id ? -1 : 0) 
});

The config parameter is added in v7.0.
