示例1: function
function history<T>(initialValue?: T): history.HistoryObservable<T> {
const self = {
latestValues: ko.observableArray([initialValue]),
selectedIndex: ko.observable(0),
canGoBack: ko.pureComputed(() => self.selectedIndex() > 0),
canGoNext: ko.pureComputed(() => self.selectedIndex() < self.latestValues().length - 1)
} as any;
ko.utils.extend(self, history.fn);
const result: any = ko.pureComputed({
read: () => {
const values = self.latestValues();
let index = self.selectedIndex();
if (index > values.length) {
index = 0;
}
return values[index];
},
write: (value: any) => {
const
index = self.selectedIndex(),
values = self.latestValues();
if (value !== values[index]) {
if (index !== values.length - 1) {
values.splice(index + 1);
}
values.push(value);
self.selectedIndex(index + 1);
}
}
}).extend({ notify: "reference" });
ko.utils.extend(result, self);
const oldDispose = result.dispose;
result.dispose = function () {
oldDispose.call(this);
this.canGoBack.dispose();
this.canGoNext.dispose();
};
return result;
}示例2: function
init: function (element, valueAccessor) {
const $element = $(element);
let value = valueAccessor(),
options = ko.unwrap(value),
id = $element.attr("id"),
oldSetup, editor;
if (typeof options === "object") {
value = options.value;
delete options.value;
}
else {
options = {};
}
if (!id) {

}
ko.utils.extend(options, defaults);

};
if ($element.is("textarea"))

}
editor = new tinymce.Editor(id, options, tinymce.EditorManager);
editor.on("change keyup nodechange", () => {
if (ko.isWriteableObservable(value)) value(editor.getContent());
});
// To prevent a memory leak, ensure that the underlying element"s disposal destroys it"s associated editor.
ko.utils.domNodeDisposal.addDisposeCallback(element, () => {
if (editor) {
editor.remove();
editor = null;
}
});
editor.render();
},示例3: trigger
export function trigger(element: HTMLElement, eventType: string, eventArgs: any): void {
let evt;
if (doc.createEvent) {
evt = doc.createEvent("HTMLEvents");
evt.initEvent(eventType, true, true);
} else {
evt = doc.createEventObject();
evt.eventType = eventType;
}
evt.eventName = eventType;
ko.utils.extend(evt, eventArgs);
if (doc.createEvent) {
element.dispatchEvent(evt);
} else {
element.fireEvent("on" + evt.eventType, evt);
}
}示例4:
crossroads.addRoute(route.url,(requestParams) => {
this.currentRoute(ko.utils.extend(requestParams, route.params));
});
