Trying to assign a value attribute to an input tag web element, but encountering the following error:
Here is the code I have used:
'document.getElementsByName('date')[0].setAttribute('value','2022-11-29');'
However, the error persists:

Any assistance on this matter would be greatly appreciated.
Thank you in advance.
It appears to me that the element named "date" is not present on this page.
Have you considered using
document.getElementsByName("date")[0].value = "2022-11-29"However, I suspect the issue lies with the selector being used.
Upon analyzing the error description, it becomes evident that the execution of the code snippet
document.getElementsByName('date')[0].setAttribute('value','2022-11-29');
reveals that there is no element with the attribute name equal to 'date'.
To troubleshoot this issue, try running the following code snippet:
document.getElementsByName('date')
This should return a NodeList that ideally contains the required element. However, if it returns empty, this could be the root cause of the error.
Alternatively, as mentioned in another response, you can update the value of the element using the following code:
document.getElementsByName("elementName")[0].value = 'newValue'
Keep in mind that this method modifies the value of the element, not the value attribute of the element.
To further investigate, you can use console.dir to inspect the element and confirm that it has a value property (which can be changed directly) and an attributes property, which is a NamedNodeMap object containing the element's attributes (set using the setAttribute method).
