ZombieJS - 如何调用 JavaScript 函数或检查 JavaScript 值？

Question

var Browser = require("zombie");

// Load the page from localhost
browser = new Browser()
browser.visit("http://localhost:3000/", function () {

  // Let's say the page has window.jQuery
  // How do I access it?

});

So, How do I access the window and the javascript variables? I want to check if my script tracks 'clicks' correctly. I want to do something like expect(browser.document.window.myScript.click_counter).toBe 5 .

Answer 1

I got it working with the following... having set the maxWait options

var opts = {
    debug: false
    , runScripts: true
    , maxWait: 10
    , waitFor: 10000
};

this.browser = new Browser(opts);

this.browser.visit(url, callback);

this.browser.wait(function(window) {
    console.log('wait...');

    return window.document.querySelector("#objectid");
}, function(e, browser) {
    console.log('wait complete ', e) ;
});

However the second callback method never fires and the querySelector call always fails. I don't think the window.document DOM is updated after the javascript injection has fired.

[edit]

I removed the callback from browser.visit() to make the wait callback fire.

this.browser.visit(url);

It depends on where you stored your variable.
If you stored it in a global object myScript , use:

browser.window.myScript.click_counter

If you have something like myScript.click_counter = 5; document.myScript = {... } myScript.click_counter = 5; document.myScript = {... } , use:

browser.document.myScript.click_counter

I needed to crank maxWait up to 100. Which is strange, because, presuming that's in ms, that's short, but in seconds, its insanely long. Its not really clear what maxWait does, but it seemed to make a difference. Unfortunately, I'm using Behat/Mink with Zombie.js and I had to hack the source of the Mink driver to make it work, which is disappointing because I can't update that driver now without problems...
