如何从Chutzpah在PhantomJS中设置视口大小

Question

How I can set viewport size in PhantomJS? I tried to set it using window.callPhantom :

window.callPhantom('page.viewportSize = { width: 480, height: 800 };')

as suggested here: https://github.com/mmanela/chutzpah/issues/355 , but this doesn't seem to work, because later window.innerHeight still shows 300px (this is the default height of viewport in PhantomJS)

Answer 1

Chutzpah supports you calling phantom to change size but it requires you pass the arguments a little bit differently. Try:

window.callPhantom(
{
  Type:"Eval",
  Data: "phantom.pagesize(100,200);"
});

I am missing documentation on this which I will correct soon.
