Golang querySelectorAll and querySelector Example by GopherJS.
querySelector
The querySelector() method returns a DOM element object:
// document object
d := js.Global.Get("document")
// return element whose css class is setting-menu
element := d.Call("querySelector", ".setting-menu")
// do something with the element ...
querySelectorAll
The querySelectorAll() method returns a NodeList:
// document object
d := js.Global.Get("document")
// return a nodelist in which the elements whose css class are about-link
nodeList := d.Call("querySelectorAll", ".about-link")
// access individual element
length := nodeList.Get("length").Int()
for i := 0; i < length; i++ {
// get i-th element in nodelist
element := nodeList.Call("item", i)
// do something with the element ...
}
Tested on: Ubuntu Linux 15.10, Go 1.5.3.
