推荐答案

没有您的html，我只能给您一个有关如何解决它的想法".

Without your html, i can only give you a "rought" idea about how to solve it.

$("div[id^='hat']").hide();隐藏所有以hat

$('div[id^="b-hat"]').click(function() {
  var id = $(this).attr("id").replace("b-","");
  $("div[id^='hat']").hide();
  $('#' + id).show(); 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hat1">hat1</div>
<div id="hat2">hat2</div>
<div id="hat3">hat3</div>
<br><br>

<div id="b-hat1">Show hat1</div>
<div id="b-hat2">Show hat2</div>
<div id="b-hat3">Show hat3</div>
