Functions

func AppendChild

func AppendChild(parent, child js.Value, populate func(child js.Value))

AppendChild adds the child object. If non-nil, the populate() function is invoked on the child to initialize it.

func DefaultQueryString

func DefaultQueryString() string

DoClick simulates a click. Any callback registered by OnClick() will be invoked.

func ID

func ID(o js.Value) string

ID returns the element ID of an object as a string.

func OnClick

func OnClick(o js.Value, callback func(ctx jsutil.AsyncContext, evt Event)) jsutil.CleanupFunc

OnClick registers a callback to be invoked when the specified object is clicked.

func OnSubmit

func OnSubmit(o js.Value, callback func(ctx jsutil.AsyncContext, evt Event)) jsutil.CleanupFunc

OnSubmit registers a callback to be invoked when the specified form is submitted.

func RemoveChildren

func RemoveChildren(p js.Value)

RemoveChildren removes all children of the specified node.

func SetValue

func SetValue(o js.Value, value string)

func (*Dialog) OnClose

func (d *Dialog) OnClose(callback func(ctx jsutil.AsyncContext, evt Event)) jsutil.CleanupFunc

func (*Doc) GetElement

func (d *Doc) GetElement(id string) js.Value

	js.Value
}

Event provides an API for interacting with events.

type URLSearchParams
