casperjs

问题 I read that people have found ways to get casperjs to work with phantomjs 2.0 but how could I do the upgrade? For example just swapping out phantomjs folder in /usr/.../casperjs/node_modules/phantomjs with a folder for phantomjs2 doesn't seem to do the trick. I've also made the changes in lib/bootstrap.js to handle the warnings from using 2.0. I'm using mocha-casperjs to create my tests. 回答1: If you want to use PhantomJS 2, then you currently need to either install CasperJS from git (which

问题 I want casperjs to make an ajax call but wait for the result from my server. This might take up to 3 minutes, but I can tell from looking at the results of running my script, casper.then function times out and just keeps going after exactly 30 seconds. I've tried putting casper.options.waitTimeout = 180000 /* 3 minutes */; in my code, which does work, and I've tried using this block of code, which seems to wait 3 minutes every single time regardless of the result of my api call. I also know

问题 In the API Documentation there is a snippet: casper.waitFor(function check() { return this.evaluate(function() { return document.querySelectorAll('ul.your-list li').length > 2; }); }, function then() { this.captureSelector('yoursitelist.png', 'ul.your-list'); }, function timeout() { this.echo("I can't haz my screenshot.").exit(); }); I need this, but in a coffeescript project. I tried to rewrite it into coffeescript but it didn’t work. Even if i let js2coffe do the job, i get some invalid

问题 I have below code snippet. var admin_url = "http://www.sampledomain.com/"; var casper = require('casper').create(); casper.start(); casper.thenOpen( "http://www.test.com", { method: "post", data: { param1: "some data" } }, function() { what_i_want = this.getPageContent().split("[")[1].split("]")[0] admin_url += what_i_want; } ); casper.thenOpen(admin_url, function() { this.echo(this.getCurrentUrl()); }); casper.run(); I first post to http://www.test.com, then use the returned data, I try to

问题 it's possible using casper function inside casper.evaluate() with jquery code inside? I need to iterare elements in a way similar to how jquery does. I'm loading jquery.js lib This is my try script: casper.evaluate(function(){ $('#size-modal .size-panel-title a').each(function(){ $(this).click(); accordionTab = $(this).attr('href'); casper.capture(screenShotOutput + "PDP-" + accordionTab +".png"); }); }); in this page there are 2 accordion and i want a screenshot for each opened accordion. It

问题 I am trying to submit a form. When I am using firefox the page will be loaded then I open the firebug I can see a input field named "content_html" but when I go to check the source of the page from "view page source" I do not see the input field "content_html" . I checked further and found out there is a javascript which will be loaded in the browser to show that input field. The code is like geteditorinit("http://example.com/pub","data[content_html]",298996,1,750,350,0,0,"content_html"); So

问题 I'm crawling multiple pages using CasperJS, but I got stuck. The maximum number of pages are 200 but I want to stop the execution if the XPath below doesn't exist (for a page before the 200th). How can I set up i variable? var casper = require('casper').create(); var x = require('casper').selectXPath; for (var i=1; i <=200; i++) { casper.wait(6000, function() { casper.thenClick(x('//*[@id="mArticle"]/div[2]/a['+i+']'), function (){ console.log('Searching dic'); words = words.concat(this

问题 I'm using a while loop to open a list of usernames from a csv file. For each username of these, I have to open a URL and dump the page into a file. However, then casper.thenOpen always runs only one time. I understood from Asynchronous Process inside a javascript for loop that this is due to that it is an asynchronous process. I need to do the same for my code below: casper.then(function(){ stream = fs.open('usernames.csv', 'r'); targetusername = stream.readLine(); i = 0; while(targetusername

问题 I am having a pretty specific problem but I hope people can point me in the right direction for how to debug or even fix it. I am trying to write a local client which can run and test a webpage I had built which uses SocketIO. I am running Phantom with the command line option --web-security=false since otherwise no in or out connections are legal as my local tester is not considered part of the same origin as my website I am testing (had to fix that before the listening would work). Using

问题 Today I tried to inject some javascript logic into remote page using CasperJS with PhantomJS together. Well, I'm quite surprised because of that: casper.then(function() { console.log(this.evaluate(function() { function myMethod() { return 'Any thing?!'; } return myMethod(); })); console.log(this.evaluate(function() { return myMethod(); })); }); I tried many combinations... Like: casper.evaluate(...) this.evaluate(...) casper.page.evaluate(...) <- directly to phantomJS this.page.evaluate(...)
