The CasperJS clicklabel allows us to click on DOM element of a kind of tag and inner text.

What if the inner text is wrapped by 2 or more levels? Will it work? For example:

<a href='xxxxxx'><span>my inner text</span></a>

I have tried the below, both seem doesn't work.

clicklabel('my inner text','a')
clicklabel('my inner text','a/span')

clicklabel('my inner text','a span')

this.click('a > span');

This will perform a click event on the first span element inside the 'a' tag.

According to the casperjs docs clickLabel's second parameter is the node name, in your case this is 'span', it doesn't take a selector. You might want to use click instead and use XPath instead of a css selector.

var x = require('casper').selectXPath;
this.click(x('//span[text()="my inner text"]'));

if you are pretty sure that the href attribute is constant just use click with something like : click("a[href='xxxxx']");

else you can try clickLabel('my inner text','span')

if both fail, check that you are not in a page which uses frames, if that's your case, check http://casperjs/api.html#casper.withFrame for how to handle it.

Good luck.

You can directly use :

clickLabel('my inner text','span');

If its not working try waiting for 5 seconds or more after the click , like :

this.wait(5000, function() {
        this.echo("I've waited for 5 seconds.");
    });

waiting for 5 seconds did the trick,as i also faced the same issue.
