casperjs

问题 I am trying to get the links from inside an iframe and return them as a function result, my simplified code looks something like this: var casper = require("casper").create({ verbose: true, logLevel: "debug", webSecurityEnabled: false }); var url = casper.cli.get(0); casper.on('remote.message', function(msg) { this.echo(msg); }) casper.start(url, function () { thelinks = getLinksFromIframes( casper ); console.log("doesn't work:" + thelinks); }); function getLinksFromIframes( context ) { var

问题 I need to make Puppeteer pause and wait for user input of username and password before continuing. It is a nodejs 8.12.0 app. (async () => { const browser = await puppeteer.launch({headless: false}); const page = await browser.newPage(); await page.goto('https://www.myweb.com/login/'); //code to wait for user to enter username and password, and click `login` const first_page = await page.content(); //do something await browser.close(); )}(); Basically the program is halted and waits until the

问题 I am trying to check wether a selector exists in my webpage but casperjs never finds it. I've tried two approaches: 1. Without waiting casper.then(function() { // search for 'casperjs' from google form this.test.assertExists('#search-form', 'the element exists'); // this.test.assertExists('.glyphicon.glyphicon-plus', 'the element exists'); }); 2. Waiting for selector casper.waitForSelector('#search-form', function() { this.echo("I'm sure #search-form is available in the DOM"); }); 3. Another

问题 I'm brand new to CasperJS and coffeescript. I have a very simple part of my CasperJS coffeescript test to login to a website, that used to work before a recent change to the password element of the login form. Unfortunately I can't remember the original form but here's how the current login form looks: <div id="login-body"> <img src="/assets/images/logo.png" class="logo" alt="Test Acme Wil-e-Coyote Company"> <form action="/Login/login/" method="post"> <h2>Please log in to catch the roadrunner

问题 Using CasperJS how do I catch and handle CasperError? The default appears to continue execution of the program (which does nothing but propagates the error). These errors are logged to the console/stdout but I don't seem to see a way (from the docs) to catch and handle these errors. Example: this.fillSelectors(selector, data); May produce: CasperError: Errors encountered while filling form: form not found I know I can check to make sure everything exists before calling, but is there a way to

问题 I have a casperjs script which gives the desired result when I run on a linux server, but when I run the same from my laptop, it doesn't work. How should I debug?

问题 I am loosing my mind over trying to do something inherently seemingly banal, but it seems almost hopeless. For a thesis project I need to collect flight prices. This code should just fill in "zurich" to the departure box. But it doesn't. This code works normally with any text imput box, but on this simple page its hopeless. I really would appreciate someones wisdom here: // variables var casper = require("casper").create(); var x = require('casper').selectXPath; var url = 'http://www

问题 As a way of learning CasperJS, I am trying to initiate a click event on a div on a remote page, and then change the class name of the div after I have clicked it. The idea is to find the first clickable div, click it, and then mark it as clicked so I can skip over it to other clickable divs. The markup for the div tag on the remote page looks like: <div class='clickable_div'></div> I have tried the following casperjs code: ... casper.then(function() { if( this.exists( 'div.clickable_div' ) )
