HTML页面会自动重新加载

Question

我有以下HTML页面：

$(document).ready(function() {
  var showChar = 380;
  var ellipsestext = "...";
  var moretext = "Read more";
  var lesstext = "Read less";
  var lesshtml="";
  var morehtml="";
  var content = $(".more").html();

  if(content.length > showChar) {

    var lastChar = content.charAt(showChar);
    if(lastChar == '/'){
      showChar = showChar+1;
    }
    var c = content.substr(0, showChar);
    var h = content.substr(showChar-1, content.length - showChar);

    var lesshtml = c + '<span class="moreelipses">'+ellipsestext+' <a href="" class="morelink">'+moretext+'</a></span>';
    var morehtml = content + '<span><a href="" class="morelink">'+lesstext+'</a></span>';
    $(".more").html(lesshtml);
  }

  $(".morelink").click(function(){

    if ($(this).text()==moretext){
      $(".more").html(morehtml);
    }else{
      $(".more").html(lesshtml);
    }
    return false;
  });
});

a {
  color: #EA7813
}
a:visited {
  color: #EA7813	
}
a.morelink {
  text-decoration:none;
  outline: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

<div class="more">

我想要的是扩张和缩小身体。扩展工作正常，但当我缩小时，页面重新加载。我想停止重装。在我的点击功能中， else 部分永远不会被触发。相反，页面重新加载。我想停止重新加载并运行 else 中的代码，以便正确收缩。

Answer 1

试试这个

    $(document).on('click', '.morelink', function(){
      if ($(this).text()==moretext){
        $(".more").html(morehtml);
      } else {
        $(".more").html(lesshtml);
      }
      return false;
    });

Answer 2

委派您的活动

 $('body').on('click','.morelink',function(e){
   e.preventDefault();
   //other code 
 });

Answer 3

您可以在href中使用#代替href中的javascript:;，而不会让网址更改

var lesshtml = c + '<span class="moreelipses">'+ellipsestext+' <a href="javascript:;" class="morelink">'+moretext+'</a></span>';
            var morehtml = content + '<span><a href="javascript:;" class="morelink">'+lesstext+'</a></span>';
            $(".more").html(lesshtml);
           }
