jQuery 自动完成不是功能控制台错误

Question

I am trying to build the autocomplete feature for the Wikipedia search API project of FreeCodeCamp. I have imported jquery and jquery-ui and have written the written the $("#searchTerm").autocomplete() function for it. Currently its printing errorMessage onto the console while running the ajax call in the autocomplete function. I have made the following js imports into the codepen.

jquery-2.2.4.min.js

jquery-ui.min.js

jqueryui/1.11.4/jquery-ui.min.js

smoothness/jquery-ui.css

Codepen 视图可以在这里找到 https://codepen.io/akshay_nayak/pen/JKvbwV?editors=1111

$(document).ready(function(){
  $('#search').click(function(){
    //get search input
    var searchterm=$('#searchTerm').val();
    
    //wikipedia url
    var url="https://en.wikipedia.org/w/api.php?action=opensearch&search="+searchterm+"&format=json&callback=?";
    
    $.ajax({
      type:"GET",
      url:url,
      aysnc:false,
      dataType:"json",
      success:function(data){
        $("#output").html("");
        for(var i=0;i<data[1].length;i++){
        $('#output').append("<li><a href="+data[3][i]+" target='blank'>"+data[1][i]+"</a><p>"+data[2][i]+"</p></li>");
        }
        $("#searchTerm").val('');
      },
      error:function(errorMessage){
       
        alert("Error");
      }
      
    });
    
  });
  $("#searchTerm").keypress(function(val){
        if(val.which==13){
          $("#search").click();
        }
  });
  
  $("#searchTerm").autocomplete({
    source: function(request, response) {
        $.ajax({
            url: "http://en.wikipedia.org/w/api.php",
            dataType: "jsonp",
            data: {
                'action': "opensearch",
                'format': "json",
                'search': request.term
            },
            success: function(data) {
              console.log(data[1]);
             response(data[1]);
             },
             error: function(errorMessage){
               console.log(errorMessage);
             }
        });
    }
});

});

事实证明，当您通过笔设置添加外部 js 库时，codepen 会重新排序导入。这导致 .autocomplete 不是函数。所以我在 html 代码中添加了这些行并解决了这个问题。

jQuery autocomplete is not a function console error

jquery

jquery-ui
