I am facing an issue with my View Model that utilizes a custom observableArray function for sorting. The error message I receive states: "...has no methods 'sortByProperty'".
How do I go about loading the handlers.js file to resolve this problem?
handlers.js:
define(['knockout'], function(ko) {
'use strict';
ko.observableArray.fn.sortByProperty = function (prop, order) {
this.sort(function (obj1, obj2) {
var result;
if (obj1[prop] == obj2[prop])
result = 0;
else if (obj1[prop] < obj2[prop])
result = -1;
else
result = 1;
return order === "desc" ? -result : result;
});
};
});
viewmodel.js:
define([
'knockout',
'js/extends/handlers'
], function(ko) {
'use strict';
var LabelsModel = function() {
var self = this;
self.availableLabels = ko.observableArray();
self.selectedLabel = ko.observable();
self.sortBy = ko.observable(); // Field to sort by
self.sortOrder = ko.observable(); // Sort order. asc or desc.
// Returns the labels for the current page
self.pagedRows = ko.computed(function() {
// Sorting of labels
return self.availableLabels.sortByProperty(self.sortBy(), self.sortOrder());
});
};
return LabelsModel;
});
