I need help identifying elements that include the letters 'ad'.
For example:
<iframe class="container" /> <!-- Not relevant -->
<a class="adp" /> <!-- Relevant -->
<a class="adleft" /> <!-- Relevant -->
<a class="some-other-class" /> <!-- Not relevant -->
Would using a forEach method be appropriate for this task?
Any assistance would be greatly appreciated.
To achieve this, you can utilize a combination of querySelectorAll and attribute selectors. Use the syntax [attr*=value].
The attribute selector syntax works as follows:
Selects elements with an attribute name of
attrcontaining at least one occurrence ofvaluein the string.
Combining the above solution will look like this:
document.querySelectorAll("[class*='ad']");
This code snippet retrieves all elements whose classes contain ad. You can then iterate over them using a loop or array helper like Array#forEach. Keep in mind that the result is an HTMLCollection, so convert it into an array before using array methods or use a traditional for loop.
Here's how the final code should appear:
const ads = document.querySelectorAll("[class*='ad']");
Array.from(ads).forEach(el => {
console.log(el);
})<iframe class="container"></iframe>
<a class="adp"></a>
<a class="adleft"></a>
<a class="some-other-class"></a>NOTE: Remember to properly open and close HTML tags, including iframe. It is not considered a self-closing tag and may lead to invalid HTML markup if not correctly formatted.
To target all elements that include the word "ad" in their class attribute, you can utilize an attribute selector. For more information on this topic, refer to this documentation.
document.querySelectorAll('*[class*="ad"]');
