问题描述

以下代码是我当前用来尝试将帖子ID提供给vote.php的代码，但是当前返回[object Object].点击链接后，如何传递正确的ID?

The following code is what I am currently using to try and give the posts ID to vote.php, however this currently returns [object Object]. How would I be able to pass the correct id when a link is clicked?

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script>
        $.ajax({  
        type: "POST",  
        data: "id=" + $(this).attr("href", "id"), 
        url: "vote.php"
        });  
</script>

<a href="javascript:;" id="1"><div id="button">Like!</div></a>
<a href="javascript:;" id="2"><div id="button">Like!</div></a>
<a href="javascript:;" id="3"><div id="button">Like!</div></a>

谢谢！

推荐答案

您需要将ajax调用绑定到点击处理程序:

You need to bind the ajax call to a click handler:

$(document).on("click","a",function(e){
    $.ajax({  
    type: "POST",  
    data: "id=" + $(this).attr("id"), 
    url: "vote.php"
    });
});
