m.mount
Mounting is the process of rendering a component into a DOM element.
The different between m.mount and m.render is that a component rendered via m.mount auto-redraws automatically when event handlers are triggered, whereas components rendered via m.render do not.
In order to allow a user to navigate between different pages by loading and unloading components, consider using m.route instead.
Rendering Components
Usage
Calling m.mount with a DOM element as the first argument and a component as the second argument will call the component's controller function, and then call the component's view function. The return value of the controller function is passed to the view function as its first argument.
var MyComponent = {
controller: function() {
return {greeting: "Hello"}
},
view: function(ctrl) {
return m("h1", ctrl.greeting)
}
}
m.mount(document.body, MyComponent)
//<body><h1>Hello</h1></body>
For more information on components, see m.component.
Signature
Object mount(DOMElement rootElement, Component component)
where:
Component :: Object { Controller, View }
Controller :: SimpleController | UnloadableController
SimpleController :: void controller([Object attributes [, any... args]])
UnloadableController :: void controller([Object attributes [, any... args]]) { prototype: void unload(UnloadEvent e) }
UnloadEvent :: Object {void preventDefault()}
View :: void view(Object controllerInstance [, Object attributes [, any... args]])
DOMElement rootElement
A DOM element which will contain the view's template.
Component component
A component is supposed to be an Object with two keys:
controllerandview. Each of those should point to a Javascript functionWhen
m.mountis called, the controller function runs, and its return value is returned by them.mountcall.Once the controller code finishes executing (and this may include waiting for AJAX requests to complete), the view class is instantiated, and the instance of the controller is passed as an argument to the view's constructor.
returns Object controllerInstance
An instance of the controller constructor
