javascript - 我是Wikipedia api调用，在jquery ajax调用后会自动重新加载页面。先显示页面内容，然后重新加载

我是jquery，通过单击按钮来搜索Wikipedia上的文章来进行api调用。ajax可以正常工作，并且还显示内容，然后重新加载。显示的内容不见了。

<h1>Wikipedia Viewer</h1>
<form class="form-inline">
  <div class="container">
    <div class="row">
      <div class="col-sm-6 col-sm-offset-4 col-lg-7 col-lg-offset-4">
        <div class="form-group">
          <label class="sr-only" for="search">search</label>
          <input type="text" class="form-control" placeholder="Search">
        </div>
        <button type="submit" class="btn btn-primary"><i class="fa fa-search"></i></button></form>
</div>
</div>

$(document).ready(function() {
  $("button").click(function() {
    var article = $("input").val();  //extract value from input box
    $.ajax({                               //wikipedia api call
      url: "https://en.wikipedia.org/w/api.php?  action=query&list=search&srsearch=" + article + "&format=json",
      dataType: "jsonp",
      success: function(data) {
        for (var i = 0; i < data.query.search.length; i++) {  //looping through json
          var title = data.query.search[i].title;             //adding data on page
          var snippet = data.query.search[i].snippet;
          $("button").append("<p>" + title + "</p>");
          $("p").append("<p>" + snippet + "</p>");
        }
      },
      error: function() {
        $("h1").html("oops");
      }
    });
  });
});

最佳答案

只需将您的按钮元素从type =“ submit”更改为type =“ button”。更新了https://codepen.io/anon/pen/Yqgoyg
