Get CasperJS to iterate over a list of URLs

I have 3 URLs to loop over looking for a file to download. 

lst = ["BX", "BL", "BM"];
lst.forEach(function(i){
    var url = 'http://www.tzg-infocenter.com/visubl_php//images/' + i + '/' + clip + '/' +  casper.cli.raw.get('entryDate') + '/' + ref + '.PDF';
    casper.start(url,function(){

        this.echo('>>> Starting URL ' + url);
    }
});
casper.run();

but only the last element is echoed. "Starting URL..." only echoes once. Why isn't Casper iterating over the whole array?

Looks like you are restarting casper on each iteration. Instead of using thenOpen after the first iteration.

thenOpen

Signature: thenOpen(String location[, mixed options])

Adds a new navigation step for opening a new location, and optionally add a next step when its loaded:...

Try the following:

var casper = require('casper').create();

var urls = ['https://google.com', 'http://casperjs.org/', 'http://phantomjs.org']

urls.forEach(function(url, idx) {

  if ( idx > 0 ) {
    casper.thenOpen( url, function() {
      this.echo(this.getTitle());
    });
  } else {
    casper.start( url, function() {
      this.echo(this.getTitle());
    });
  }

})


casper.run();
