jQuery's invalid solution for removing tr (tr is added dynamically)_jquery

When I was working on a project today, I encountered a problem, which was to remove some tr (tr was added dynamically). I have tried many methods, but none of them work (for example, in the deleteRow method, it seems that the parameter passed can only be the number of rows of tr. I have not studied it carefully so far). Later, I found that this method worked well, so I recorded it here.

$(temp).parent().remove(); //temp为td的id 
code class="js plain"> 我的理解是这样的：$(temp)先获取到该td对象，然后.parent()获取到td的tr，再remove()方法，删除tr。</code>

html code:

<table> 
<tr> 
<td><a href='#' onclick='removeTr(this)'>123</a></td> 
<td><a href='#' onclick='removeTr(this)'>456</a></td> 
</tr> 
<tr> 
<td><a href='#' onclick='removeTr(this)'>aaa</a></td> 
<td><a href='#' onclick='removeTr(this)'>bbb</a></td> 
</tr> 
;/table>

js code:

function removeTr(temp){ 
mp).parent().parent().remove(); //必须保证页面已经引入了jQuery才可以使用 
//此处$(temp)先获取到<a>对象，.parent()拿到<td>，再.parent()获取到tr 
}
