覆盖JavaScript函数ag-grid

Question

there is a functionality that i need to change in ag-grid, and for this i need to change a function, for example from:

 NumberFilter.prototype.onFilterChanged = function () {

            var filterText = utils_1.default.makeNull(this.eFilterTextField.value);

            if (filterText && filterText.trim() === '') {
                filterText = null;
            }
            var newFilter;
            if (filterText !== null && filterText !== undefined) {

            console.log(filterText);


                newFilter = parseFloat(filterText);
                console.log(newFilter);
            }
            else {
                newFilter = null;
            }
            if (this.filterNumber !== newFilter) {
                this.filterNumber = newFilter;
                this.filterChanged();
            }
        };

To

 NumberFilter.prototype.onFilterChanged = function () {

            var filterText = utils_1.default.makeNull(this.eFilterTextField.value);

            if (filterText && filterText.trim() === '') {
                filterText = null;
            }
            var newFilter;
            if (filterText !== null && filterText !== undefined) {

            console.log(filterText);

                // replace comma by dot
                newFilter = parseFloat(filterText.replace(/,/g, '.'));
                console.log(newFilter);
            }
            else {
                newFilter = null;
            }
            if (this.filterNumber !== newFilter) {
                this.filterNumber = newFilter;
                this.filterChanged();
            }
        };

How can i overwrite the functionality in th ag-grid configuration file? Above i leave a demo example with the configuration file:

Duplicate here : Ag-grid inheritate functionality

I'm reposting my answer from there

You should use Javascript inheritance on NumberFilter and then overtwrite the method onFilterChanged. Check this answer to see how to do it : JavaScript override methods

Then instead of specifying

filter:'number'

You can do :

filter:new MyNumberFilter();

As you can see i instanciated the filter, it's required or you will have the same instance for all your number column's filter on the grid.
