比如将这个页面 div id=“content” 的内容保存为图片
用casperjs的话可以方便地用captureSelector()，phantomjs的话可能要自己调整视窗位置了吧？ 自豪地采用 CNodeJS ionic
你也可以用nightmare
var Nightmare = require('nightmare');
var Screenshot = require('nightmare-screenshot');
var nightmare = new Nightmare();
nightmare
.viewport(1024, 700)
.goto(pageUrl)
.use(Screenshot.screenshotSelector(tempPath, '.question-answer-detail'));
var casper = require("casper").create({
verbose: true,
logLevel: "debug",
pageSettings: {
loadImages: true,
loadPlugins: false,
userAgent: 'Mozilla/5.0 (Windows NT 6.1; rv:17.0) Gecko/20100101 Firefox/17.0'
},
onError: function(self,m){
this.capture("error.png");
console.log("FATAL:" + m);
self.exit();
}
});
截图成功了,但是对应的div里面的图片是空的,这是什么原因
@okoala 运行提示没有模块Weak

@yakczh 应该是你的环境问题，卸载Visual C++ redistributable 然后重新安装 Windows SDK 7 SP1，windows下安装一些模块很麻烦，这种情况下建议使用virtualbox虚拟机，共享开发目录，在linux下运行node。
