By the way, getElementsByTagName returns HTMLCollection and you can get single item also in this way:
linkElements[i].setAttribute("target", "_self")
Finally, you incorrectly compare whether the target equals _blank. You used "=" which means you are assigning this value. You must use "==" or "===" operator. Please refer to the MDN documentation.
Need help: getAttribute and setAttribute
in JavaScript

Hi!
item is a function, not an object, so you must call it:
linkElements.item(i).setAttribute("target", "_self")By the way, getElementsByTagName returns HTMLCollection and you can get single item also in this way:
linkElements[i].setAttribute("target", "_self")Finally, you incorrectly compare whether the target equals _blank. You used "=" which means you are assigning this value. You must use "==" or "===" operator. Please refer to the MDN documentation.
