jquery onclick只从一个输入中获取php文件中的数据

Here is the HTML (This form may use more than twice) :-(

这是HTML(此表单可能使用两次以上):-(

<div class="abc">
  <div class="xyz">
    <input type="text" name="pqr" />
    <div class="clickMe">click button</div>
    <div class="showContent"></div>
  </div>
  <div class="somethingelse">some other insignificent input or something else.</div>
</div>

Here is the jQuery:

这是jQuery:

$('.clickMe').on('click', function(e){

    $.post("getdata.php", $(this).closest('.abc').children('.xyz').children('input[name="pqr"]').serialize(),  function(response) {
        $(this).closest('.abc').children('.xyz').children('.showContent').html(response);
    });

});

i need only to check data of input(pqr) with my database?
any idea, how can i it and what is wrong on my code!
Advance thanks.

The scope of this inside of the post is not the same as outside

帖子内部的范围与外部不同

$('.clickMe').on('click', function(e){
    e.preventDefault();
    var xyz = $(this).closest('.abc').children('.xyz');
    $.post("getdata.php", xyz.children('input[name="pqr"]').serialize(),  function(response) {
        xyz.children('.showContent').html(response);
    });    
});
