The following is the HTML of the page. I want to use JS to operate the DOM and delete the first table from the page.
The code I used is:
document.getElementsByTagName("table")[0].innerHTML=""; //没效果
OR
document.getElementsByTagName("table")[0].parentNode.removeChild("table")
错误信息:Uncaught TypeError: Failed to execute 'removeChild' on 'Node': parameter 1 is not of type 'Node'.

innerHTML changes the content in the table, not deletes the table. Of course, it seems from the page that innerHTML="" has almost the same effect as deletion. As for why your innerHTML="" has no effect, I'm sorry, the HTML code is too long. I didn’t look at it carefully
The parameters passed in removeChild are nodes, not strings
removeChild
accepts an HTMLElement element, soremoveChild(document.getElementsByTagName("table")[0])
