Unable to retrieve embedded link using fetchText function in casperjs

Exploring the capabilities of Casperjs provides a valuable opportunity to test specific functions across different websites.

The website used in this scenario serves as a tutorial illustration.

An interesting challenge arises with an embed code that cannot be console.logged using fetchText through Casperjs. This embed code can potentially be placed on personal blogs to direct users towards particular content, such as a music album:

The desired element for extraction is as follows:

<a href="https://geo.itunes.apple.com/us/album/a-head-full-of-dreams/id1053933969?mt=1&amp;app=music" target="_blank">https://geo.itunes.apple.com/us/album/a-head-full-of-dreams/id1053933969?mt=1&amp;app=music</a>

A visual representation from the inspector highlights key details: https://i.sstatic.net/lJgbJ.png

Furthermore, two snapshots reveal a larger segment of the markup:

https://i.sstatic.net/Iwlr0.png

https://i.sstatic.net/Ov9A4.png

Below you can find the code snippet utilized for this task:

var theTextIWant = casper.fetchText(x('//*[@id="695806055"]/div[4]/div[2]'));
 console.log(theTextIWant);

No errors are encountered, and the script performs flawlessly with other links or text fragments on the page, like so:

var theTextIWant = casper.fetchText(x('//*[@id="1053933969"]/div[4]/div[2]/a'));
 console.log(theTextIWant);

Despite thorough research within Casperjs documentation, no alternative method to fetchText for the embed code was found. Could there be a feature or detail overlooked within the Casperjs resources that would facilitate console.logging the embed code?

Your assistance and insights on this matter are greatly valued!

If additional information is required, please do not hesitate to reach out.

Answer №1

If you're looking to extract the content from a textarea, using casper.fetchText() won't work as expected. This method only combines TextNodes from child elements of the selected context, but since a <textarea> doesn't contain TextNodes like an <input>, you need to access the value property of the textarea within the page context:

casper.then(function(){
    this.echo(this.evaluate(function(){
        return document.getElementById("link-code").value;
    }));
});
