Casper.js的sendEvent在哪里定义？

Question

I'm trying to figure out how exactly is Casper.js using underlying Phantom.js to move the mouse .

I found that casper.page.sendEvent() is responsible but where is sendEvent defined and how does it interact with PhantomJS?

Answer 1

Since CasperJS is built on top of PhantomJS, you can use any PhantomJS function inside a CasperJS script through the casper.page object.

One such function is page.sendEvent which enables you to trigger native user events in PhantomJS.

The documentation says the following for mouse move:

For 'mousemove', however, there is no button pressed (ie it is not dragging).

If you still want to see how it is implemented, you can find it here .
