Phantom.js没有在$（document）.ready中加载内容

标签： jquery node.js firebase-realtime-database phantomjs phantomjs-node

我正在使用PhantomJS来截取我的页面但我遇到了一些问题。当从Firebase检索数据时，我的页面内容通过jQuery呈现90％。我正在使用phantomjs-node，因为我正在通过Nodejs构建我的网站。

我希望在Firebase的数据填充网页后截取屏幕截图，但它似乎不起作用。

我的nodejs文件：

var renderSendInvoice = function(req,res){

var id = req.query["id"]
var url = "http://localhost:5001/invoicePrint.html?id="+id;

phantom.create().then(function(ph) {
ph.createPage().then(function(page) {

  page.setting('javascriptEnabled',true);
  page.setting("userAgent", 'Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0');

  page.property('viewportSize', {width: 794, height: 1122});
  page.property('onCallback',function(data) {
    console.log("called");
  });

  page.on('onLoadFinished', true, function (requestData, 
networkRequest) {
      console.log("load finish already");

  });

    page.open(url).then(function(){

        console.log("open page");
        page.render("test.pdf", function(err){
        ph.exit()
      });

    });
  });
 });
};

我的Html文件：

我的HTML网页有效，因为如果我在没有PhantomJS的情况下单独加载它，所有内容都会完美加载。但是，如果我使用phantomjs并渲染页面，那么在加载jQuery脚本之前，我得到的只是HTML的静态内容。只打印HTML正文中的那些，但不打印整个站点。见图：

enter image description here

我试过延迟10000毫秒，但我仍然得到相同的截图。

我得出的结论是，jQuery根本没有在phantomjs中加载，但我不确定如何对其进行故障排除（以确认jQuery未加载）。

我尝试使用onCallback并在我的html中包含window.callPhantom()，但它也从未被回调过。
