casperjs

问题 Trying to scrape a web page with CasperJS. Webpage checks to see if the browser is an IE 6/7. Passing an userAgent with casperjs doesn't seem to satisfy its condition. UserAgent passed: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Following is the check being made by the page to determine the browser agt = navigator.userAgent.toLowerCase(); browserType = navigator.appName; if( ((browserType.indexOf("xplorer") != -1) && (agt.indexOf("msie 6.") != -1)) || ((browserType.indexOf("xplorer")

问题 Every since the sslv3 POODLE bug came out I am unable to use casperjs with the "--engine=slimerjs" option. Before POODLE I was able to run my casperjs script like this: casperjs --engine=slimerjs script.js But after POODLE I needed to also send the "--ssl-protocol=tlsv1" to casperjs. This works without using the slimer option like this: casperjs --ssl-protocol=tlsv1 script.js Now if I want to use the slimerjs engine and send the ssl-protocol like this: casperjs --ssl-protocol=tlsv1 --engine

问题 I'm trying to use CasperJS to follow a link that's in an iframe but I can't seem to get at the iframe's document. Here's a test using an iframe example page I found.

I use maily SimpleBrowser, so I am new with CasperJS, I googled some scripts, read documentation and then combined following script.

问题 I am currently able to scroll down a page with the help of CasperJS. I saw this article on how to scroll infinite pages based on the visibility of certain attributes. However I don't want to base it on the visibility of an element but was wondering if there is a way to set a timer on how long it should stay scrolling down before exiting out. How would be able to such thing? //function to scroll function tryAndScroll(casper) { casper.page.scrollPosition = { top: casper.page.scrollPosition["top

问题 I am trying to use jQuery and casperjs to click an element retrieved from the DOM. casper.options.clientScripts = ["jquery-1.11.1.min.js"]; ... ... casper.then(function() { this.wait(2000,function() { this.evaluate(function() { var element = $('h4:contains("test")').prev().find('.delete'); $(element).css("background-color", "red"); $(element)[0].click(); }); }); )}; I have used $(element).css("background-color", "red"); to see exactly what element jquery is selecting, (I have used capture()

问题 This question was migrated from Software Engineering Stack Exchange because it can be answered on Stack Overflow. Migrated 5 years ago . I am trying to pass CasperJS results to PHP but it's not working (the output is empty). Here is my code: <?php exec("casperjs test.js", $array); print_r($array); ?> The exec works for any other command ("echo hello"), but not casperjs. $array is empty and execution time is instantaneous...
