javascript - Casperjs随机延迟

Question

我使用 casperjs，我想以随机时间间隔在站点中移动。我做了这样的代码，但它没有工作:

function getRandomIntFromRange(min, max) {
  return Math.round(Math.random() * (max - min)) + min;
}


var casper = require('casper').create();
casper.start('http://stackoverflow.com/');

casper.on('remote.message', function(msg) {
  this.echo('remote message caught: ' + msg);
});

casper.then(function() { 
  for (i=0; i<=5; i++) { 
    delay = getRandomIntFromRange(1000, 5000);
    this.wait(delay, (
      function(j) { 
        return function() { 
          this.echo('Test ' + j + '; delay: ' + delay); 
        }; 
    })(i)); 
  } 
}); 

casper.run();

输出是这样的:

测试0；延迟:1320

测试 1；延迟:1320

测试 2；延迟:1320

测试 3；延迟:1320

测试 4；延迟:1320

测试5；延迟:1320

casper.then(function() { 
  for (i=0; i<=5; i++) { 
    delay = getRandomIntFromRange(1000, 5000);
    this.wait(delay, (
      function(j,d) { 
        return function() { 
          this.echo('Test ' + j + '; delay: ' + d); 
        }; 
    })(i,delay)); 
  } 
});
