如何拖放纯粹的幻影？

Question

如果没有casperjs，selenium等，如何拖放纯粹的幻影？

我尝试了这段代码，但它不起作用

var page = new WebPage();
page.open("http://html5demos.com/drag", function()
{
  var coordOne = page.evaluate(function() { return document.getElementById("one").getBoundingClientRect(); });    
  var coordBin = page.evaluate(function() { return document.getElementById("bin").getBoundingClientRect(); });

  console.log(coordOne.left + "x" + coordOne.top);  
  console.log(coordBin.left + "x" + coordBin.top);

  page.sendEvent("mousemove", coordOne.left, coordOne.top);
  page.render('screenshot1.png');

  page.sendEvent("mousedown", coordOne.left, coordOne.top);  
  page.sendEvent("mousemove", coordBin.left, coordBin.top); 
  page.sendEvent("mouseup", coordBin.left, coordBin.top);  
  page.render('screenshot2.png');

  phantom.exit();
});

我读到它在html5中不起作用。在普通代码中它起作用：

var page = new WebPage();
page.open("http://www.snook.ca/technical/mootoolsdragdrop/", function()
{
  var coordOne = page.evaluate(function() { return document.getElementById("dragger").getBoundingClientRect(); });    
  var coordBin = page.evaluate(function() { return document.getElementsByClassName("item")[0].getBoundingClientRect(); });

  console.log(coordOne.left + "x" + coordOne.top);  
  console.log(coordBin.left + "x" + coordBin.top);

  page.sendEvent("mousedown", coordOne.left+1, coordOne.top+1);  
  page.sendEvent("mousemove", coordBin.left+1, coordBin.top+1);
  page.sendEvent("mouseup", coordBin.left+1, coordBin.top+1);  

  page.render('screenshot.png');
  phantom.exit();
});
