javascript - Function is not being executed when split into multiple functions -
i writing script using casperjs , have function:
extractor.prototype.get_links       = function() {                                                                                                                     var links   = document.queryselectorall('p.title a');                                                                                                               homecoming array.prototype.map.call(links, function(element) {                                                                                                              homecoming element.getattribute('href');                                                                                                                           });                                                                                                                                                            };    which works fine , desired result. when seek create new function , phone call it, so:
function test_this() {     var links   = document.queryselectorall('p.title a');                                                                                                               homecoming array.prototype.map.call(links, function(element) {                                                                                                              homecoming element.getattribute('href');                                                                                                                           }); };  extractor.prototype.get_links       = function() {     test_this(); };    this casper.start method:
casper.start(webpage, function() {                                                                                                                                             var extractor   = new extractor();                                                                                                                                         links  = links.concat(this.evaluate(extractor.get_links)); });                                        it seems function not beingness called, , not desired result. new casperjs , javascript, , cannot seem figure out doing wrong.
casper.evaluate sandboxed. interface page context. variables defined outside of page context not accessible outside.
in case test_this defined outside of page context. define through separate evaluate if want separation:
casper.start(webpage, function() {     this.evaluate(function(){         function test_this() {             var links   = document.queryselectorall('p.title a');                                                                                                                       homecoming array.prototype.map.call(links, function(element) {                            homecoming element.getattribute('href');                                                                     });         }     });      var extractor   = new extractor();     links  = links.concat(this.evaluate(extractor.get_links)); });           javascript phantomjs casperjs
