Jquery树遍历不选择
我有一些 jquery 变量试图获取附近元素的值，但它们不起作用。我认为closest()是正确的选择器。
JQUERY：
$(".answerContainer").on("click", ".editAnswer", function(e){
e.preventDefault();
var answer_id = $(this).closest('.answer_id').attr('value'); //this doenst work
HTML：
<p name='singleAnswer' class='singleAnswer'>$answer[$f]</p>
<input type='hidden' value='$answerid[$f]' class='answer_id' />
<p class='ratingBox'> $answerrating[$f]</p>
<div class='answerBar'>";
<a href='#' class='upVote vote'>Upvote</a> · <a href='#' class='downVote vote'>Downvote</a> ·
<a class='answerTime'> $difference $periods[$j] ago</a>
· <a href='#' style='color: orange;' class='editAnswer'><b>Edit</b></a>
I have some jquery variables that attempt to get values of nearby elements however they don't work. I thought closest() was the right selector.
JQUERY:
$(".answerContainer").on("click", ".editAnswer", function(e){
e.preventDefault();
var answer_id = $(this).closest('.answer_id').attr('value'); //this doenst work
HTML:
<p name='singleAnswer' class='singleAnswer'>$answer[$f]</p>
<input type='hidden' value='$answerid[$f]' class='answer_id' />
<p class='ratingBox'> $answerrating[$f]</p>
<div class='answerBar'>";
<a href='#' class='upVote vote'>Upvote</a> · <a href='#' class='downVote vote'>Downvote</a> ·
<a class='answerTime'> $difference $periods[$j] ago</a>
· <a href='#' style='color: orange;' class='editAnswer'><b>Edit</b></a>

尝试一下，也使用
.val()而不是attr('value')Try this, also use
.val()instead ofattr('value')Closest 假设您要遍历节点的祖先。在这种情况下，请尝试 prev()
Closest assumes you want to traverse through the ancestors of the node. In this case, try prev()
