问题 I'm trying to use CasperJS to upload images to a web-form. My form looks something like this: <form action="" method="POST" enctype="multipart/form-data" class="form-vertical"> ... <legend>Campaign Banner</legend> <div class="control-group image-field "> <label class="control-label">Now Large</label> <div class="controls"> <div class="file-field"><input id="id_now_large_image" name="now_large_image" type="file"></div> <div class="image-preview"></div> <div class="clear"></div> <span class=

问题 I'm trying to scrape a number of pages that have a standard format. I've been able to use Phantomjs to successfully scrape a single page, but when I try to iterate over multiple ones, the asynchronous processing makes things hang up. What's the proper way to tell Casper/Phantom to wait? var page = require('webpage').create(); var fs = require('fs'); page.onConsoleMessage = function(msg) { phantom.outputEncoding = "utf-8"; console.log(msg); }; // this overwrites the previous output file f = fs

问题 I'm new to CasperJS and I'm having a few issues getting the innerHTML out of <p class="city">Data I Need</p> I have tried a few things, but nothing seems to get it. var city_name= casper.evaluate(".//*[@class='city_name']", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue; var friend_username = city_name.innerHTML; and var city_name = this.evaluate(function() { return document.querySelector(".//*[@class='city_name']").innerHtml; }); 回答1: CasperJS works by default

问题 I want to be able to have a set of Casper JS tests and get an exit code back of 0 on success and non-zero on error or test failure (I want to run the casper command from java and determine if a test passed). The problem I am having is that an exit code of 0 is always returned. Here is an example test where this happens: var casper = require('casper').create(); casper.start('http://www.google.com', function() { this.test.assertEquals(true, casper.cli.options['value']); }); casper.run(function(

问题 Well , I would like to know how to get back the information of a test failed in jenkins. Here the result of my folder (fr) (it displays 22 min. but in parallel it's 3min) : Here the description of the test failed -jenkins- : Here the description of the test failed -casper- : So my problem is jenkins displays only the message of the test failed, and I would like to have also useful information as line and code (in fact there is the console output but it's not convenient-> I've changed my mine,

问题 casper.then(function(){ phone_number = '7wqeqwe6'; phone_password = 'Teqweqweqw34'; }); casper.thenEvaluate(function(phone,password) { document.querySelector('input#myTMobile-phone').setAttribute('value',phone); document.querySelector('input#myTMobile-password').setAttribute('value',password); // document.querySelector('form').submit(); }, { phone : phone_number, password : phone_password }); this throws me string(307) "[37;41;1mFAIL[0m ReferenceError: Can't find variable: phone_number Is

问题 I am just curious how CasperJS handles events with regards to the call stack. Let's say we have some code: casper.on('foo', function() { this.wait(60000); this.echo('foo'); }); casper.start('http://www.stackoverflow.com', function() { this.echo('start'); this.emit('foo'); }); casper.then(function() { this.echo('done'); }); casper.run(); I know that then() will wait check against 3 flags: pendingWait, loadInProgress, and navigationRequested. Printing out the call stack shows the emit call to

问题 I was wondering how we could set cli parameters inside our code and not by placing them at the end of our command like this: casperjs casper_tor.js --proxy=127.0.0.1:9050 --proxy-type=socks5 I've tested things like that but it didn't work: var casper=require('casper').create(); casper.cli.options["proxy"] = "127.0.0.1:9050"; casper.cli.options["proxy-type"] = "socks5"; ... casper.run(); What I'm trying to achieve is to set new proxies inside my code and to scrap my new ip address from

问题 I recently tried to login into a webiste that forces me to accept cookies. I'm using phantomJs and casperJs. I wrote a little script that should handle the login, but it redirects me to a site that tells me I have to accept cookies. Email and password are just placeholders. The site I want to login is https://de.buyvip.com/ . But I need to click the button Anmelden mit Amazon so I can login with my amazon account. The other login form does not work. (That leads to this long url, I just copied

问题 I have been writing tests for my Ruby code for a while, but as a frontend developer I am obviously interested in bring this into the code I write for my frontend code. There is quite a few different options which I have been playing around with: CasperJS Capybara & Rspec Jasmine Cucumber or just Rspec What are people using for testing? And further than that what do people test? Just JavaScript? Links? Forms? Hardcoded content? Any thoughts would be greatly appreciated. 回答1: I had the same
