PhantomJS中的评估似乎不起作用 [英] Evaluate in PhantomJS doesn't seem to work

问题描述

我遇到了JavaScript魔术问题。当我执行此代码时：

I have a problem with JavaScript magic. When I execute this code:

var page = require('webpage').create();
var url="http://google.com";
page.open(url, function (status){
  if (status!== "success") {
    console.log("Fail to load: "+url)
  }else{
    console.log('1');
    page.evaluate(function() {
      console.log('2');
      });   
    console.log('3');
  }
phantom.exit();
});

控制台只有1和3而且没有2.有人可以说为什么？

console have only 1 and 3 and no 2. Can anyone say why?

如果我在代码后粘贴 DOM操作示例（但它永远不会执行）我有我的两个。我忘记了重要的事情吗？

If I paste after my code DOM manipulation example (but it never execute) I have my two. Did I forget something important?

推荐答案

默认情况下，PhantomJS不会在.evaluate（）语句中记录控制台消息。只需包含

PhantomJS won't log console messages in .evaluate() statements by default. Just include

page.onConsoleMessage = function (msg) {
    console.log(msg);
};
