截取整个屏幕，获取验证码坐标及大小，然后再截取验证码：

<?php
$element = $webDriver->findElement(
  WebDriverBy::id('J-checkcode-img')
);
$element_width = $element->getSize()->getWidth();
$element_height = $element->getSize()->getHeight();
 
$element_src_x = $element->getLocation()->getX();
$element_src_y = $element->getLocation()->getY();
 
$webDriver->takeScreenshot('screenshot.png');
$src = \imagecreatefrompng('screenshot.png');
$dest = \imagecreatetruecolor($element_width, $element_height);
 
imagecopy($dest, $src, 0, 0, $element_src_x, $element_src_y, $element_width, $element_height);
imagepng($dest, './captcha.png');

通过v8，windows下需自行编译：

d8 a.js -- a b c
d8 a.js --js-arguments a b c

获取参数：

print(arguments[0]);

通过spidermonkey，获取参数同上：

js a.js a b c

通过Nodejs，底层基于v8，官网有windows安装包：

node a.js a b c

获取命令参数：

var arguments = process.argv.splice(2);
console.log(arguments[1]);

v8和spidermonkey都有相应的php扩展，在windows下通过进程调用执行js并获取结果：

<?php
$lastline = exec("node a.js aa bb", $res, $ret);
print_r($res);
echo $lastline;
echo $ret;
