我有一个热量变数,有热量工作,最喜欢干,因为我不知道如何适当选择要素。 我认为,以下选择人会工作,但他们不会工作。

JQUERY:

$( .upVote ).click(function(e){
    e.preventDefault();
    var ratebox = $(this).find( .ratingBox );  //this variable isnt working
    var answer_id = $(this).children( .record_id ).attr( value );  //this one too 

传真:

<p class= ratingBox > $answerrating[$f]</p>
<div class= answerBar >";
    <a href= #  class= upVote vote >Upvote</a> 
    &middot;
    <a href= #  class= downVote vote >Downvote</a>  
    <a class= answerTime > $difference $periods[$j] ago</a>
</div> 
<input type= hidden  name= record_id  value= $answerid[$f]  class= record_id  />
最佳回答

<find(>children(>>>>将寻找低于目前水平的电离层扰动树元素,而你重新研究的成分则较高。 为此:

var ratebox = $(this).closest( .answerBar ).prev(".ratingBox");
var answer_id = $(this).closest( .answerBar ).next( .record_id ).attr( value );

Fiddle to evidence:

问题回答

使用时应当使用<条码> 括号/代码>、<条码> 之前和<条码>。 由于findchildren将研究不按您的标记操作的内容。 引言

$( .upVote ).click(function(e){

  e.preventDefault();
  var ratebox = $(this).parent().prev( .ratingBox );  //this will work now
  var answer_id = $(this).parent().next( .record_id ).attr( value );  //this too

});
