我有一个带有iframe的网页。我想使用CasperJS访问iframe的内容。特别是,我需要点击按钮并填写表格。我怎样才能做到这一点?如何从CasperJS访问iframe?
主要网页是 main.html:
<html><body>
<a id='main-a' href="javascript:console.log('pressed main-a');">main-a</a>
<iframe src="iframe.html"></iframe>
<a id='main-b' href="javascript:console.log('pressed main-b');">main-b</a>
</body></html>
的iframe是:
<html><body>
<a id='iframe-c' href="javascript:console.log('pressed iframe-c');">iframe-c</a>
</body></html>
我天真的做法:
var casper = require('casper').create({
verbose: true,
logLevel: "debug"
});
casper.start("http://jim.sh/~jim/tmp/casper/main.html", function() {
this.click('a#main-a');
this.click('a#main-b');
this.click('a#iframe-c');
});
casper.run(function() {
this.exit();
});
不行的,当然,这是因为a#iframe-c
选择器在主框架中无效:

有没有什么方法可以使这项工作?涉及直接窥探幻影的黑客攻击会很好,但我不知道该怎么做。
我使用CasperJS版本1.0.0-RC1和phantomjs版本1.6.0。
吉姆,你碰巧知道你是否可以切换后this.test.assertVisible('#someElemInsideIframe')?似乎barf为我,但this.click(...)的作品。 –
我不会,对不起。可见性可能会以某种其他方式进行测试,但对框架效果不佳,我不确定。 –
您是否看到@ olleolleolle的回答? withFrame是一种记录方法。 –
