Jquery自动完成不填充文本框

Question

我有一个自动完成功能，可以过滤本地 json 以将结果返回到文本框，但是在选择位置时，自动完成功能不会填充文本框。我试图根据文档包含一个select 方法，但它破坏了我的功能。我应该在我的代码库中的什么位置包含select？

自动完成功能：

  $('#autocomplete').autocomplete({
      minLength: 1,
      source: function(request, response) {
              var data = $.grep(suggestion, function(value) {
                  return value.city.substring(0, request.term.length).toLowerCase() == request.term.toLowerCase(); // Here the suggestion array is filtered based on what the user has typed. User input will be captured in the request.term
              });

              response(data); // this will return the filtered data which will be attached with the input box.
      }

     }).data( "ui-autocomplete" )._renderItem = function( ul, item ) {

                  return $( "<li></li>" )
                      .data( "ui-autocomplete-item", item )
                      .append( "<a>" + item.city + "," + item.country + "</a>" )
                      .appendTo( ul ); // here we are creating and appending appending element based on the response object we got after filtering
              };

    });

数据

在您的情况下，选择可以放在源之前或之后，只要它作为属性保留在自动完成对象中即可。你可以按照这个例子：

$('#autocomplete').autocomplete({
    minLength: 1,
    source: function (request, response) { ... },
    select: function (event, ui) {
        event.preventDefault();
        // [...] your code here
        return false;
    }
}).data( "ui-autocomplete" )._renderItem = function( ul, item ) { ... };
