jQuery的Textarea的重点

问题描述

当我点击一个按钮时，我希望这个 li 元素中的 textarea 来关注。 b
$ b

 < li class =commentBlockid =commentbox-79style =display：list-item;> 
< div> 
< div class =grid userImageBlockS> 
< div class =imgSmall> 
< img width =35height =35alt =imagesrc =/ bakasura1 / files / images / small / 1288170363aca595cabb50.jpg> 
< / div> 
< / div> 
< div class =grid userContentBlockS alpha omega> 
 < div style =display：none;> 
< input type =hiddenvalue =POSTname =_ method> 
< / div> 
< input type =hiddenid =StatusMessageReplyPidvalue =79name =data [StatusMessageReply] [pid]> 
< input type =hiddenid =StatusMessageReplyItemIdvalue =1name =data [StatusMessageReply] [item_id]> 
< input type =hiddenid =StatusMessageReplyCommentersItemIdvalue =1name =data [StatusMessageReply] [commenters_item_id]> 
< textarea id =StatusMessageReplyMessagename =data [StatusMessageReply] [message]> 
写下您的评论... 
< / textarea> 
< input type =submitname =value =Commentclass =commentid =comment-79> 
< / form> 
< / div> 
< div class =clear>< / div> 
< / div> 
< / li> 
  

这是我的 jQuery （$。

$ $ $ $ $''code $（'。user-status-buttons'）。click（function（）{
var id = $（this ）.attr（'id'）;
$（＃commentbox - + id）.slideToggle（fast）;
$（＃commentbox - + id +#StatusMessageMes​​sage）。 focus（）;
返回false;
}）;

解决方案

想要：

  $（'。user-status-buttons'）。click（function（）{
 
 $ id $（this）.attr（'id'）; 
 $（＃commentbox  - + id）.slideToggle（fast，function（）{
 $ （）; 
}）; 
 
 return false; 
}）; 
  

这应该给 #StatusMessageReplyMessage 元素焦点 之后幻灯片效果已经完成。

When I click a button I want the textarea in this li element to focus.

<li class="commentBlock" id="commentbox-79" style="display: list-item;">
  <div>
    <div class="grid userImageBlockS">
      <div class="imgSmall">
        <img width="35" height="35" alt="image" src="/bakasura1/files/images/small/1288170363aca595cabb50.jpg">
      </div>
    </div>
    <div class="grid userContentBlockS alpha omega">
      <form accept-charset="utf-8" action="/bakasura1/account/saveComment" method="post">
        <div style="display: none;">
          <input type="hidden" value="POST" name="_method">
        </div>
        <input type="hidden" id="StatusMessageReplyPid" value="79" name="data[StatusMessageReply][pid]">
        <input type="hidden" id="StatusMessageReplyItemId" value="1" name="data[StatusMessageReply][item_id]">
        <input type="hidden" id="StatusMessageReplyCommentersItemId" value="1" name="data[StatusMessageReply][commenters_item_id]">
        <textarea id="StatusMessageReplyMessage" name="data[StatusMessageReply][message]">
          Write your comment...
        </textarea>
        <input type="submit" name="" value="Comment" class="comment" id="comment-79">
      </form>
    </div>
    <div class="clear"></div>
  </div>
</li>

This is my jQuery code:

$('.user-status-buttons').click(function() {
    var id = $(this).attr('id');
    $("#commentbox-"+id).slideToggle("fast");
    $("#commentbox-"+id+" #StatusMessageMessage").focus();
    return false;
});

解决方案

Based on your comment in reply to Jacob, perhaps you want:

$('.user-status-buttons').click(function(){

    var id = $(this).attr('id');
    $("#commentbox-"+id).slideToggle("fast", function(){
        $("#commentbox-"+id+" #StatusMessageReplyMessage").focus();
    });

    return false;
});

This should give the #StatusMessageReplyMessage element focus after the slide effect has finished.
