使用CasperJS时，网页的反应不同

Question

当在Chrome浏览器上执行用于点击按钮的jQuery代码$('.reply_button').click()时，菜单会按预期弹出。但是，当在CasperJS中的this.evaluate内执行相同的jQuery代码时，网页会显示加载屏幕。

为什么页面反应不同，我们如何才能像使用Chrome浏览器一样获取弹出窗口？

CasperJS代码

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

casper.options.pageSettings = {
    loadImages:  true, 
    loadPlugins: false,
    userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X)'
}

casper.start("http://raleigh.craigslist.org/apa/5167043093.html", function() {
    this.evaluate(function() {
        $('.reply_button').click()
    })
})


casper.wait(5000, function() {
     this.capture('1.png')
})

casper.run()

尝试原生点击而不是合成点击

仍然触发验证码

casper.start("http://raleigh.craigslist.org/apa/5167043093.html", function() {
    var rect = casper.page.evaluate(function() {
        return $('.reply_button')[0].getBoundingClientRect();
    });
    casper.page.sendEvent('click', rect.left + rect.width / 2, rect.top + rect.height / 2);
})
