Jquery 自动完成 _renderItem 不起作用 [英] Jquery autocomplete _renderItem is not working

问题描述

_renderItem 根本没有执行，尝试使用 console.log 也没有打印任何消息.尝试使用 'autocomplete'、'ui-autocomplete'、'Autocomplete' 属性没有希望.

_renderItem is not executing at all, tried with console.log too no messages printed. Tried with 'autocomplete', 'ui-autocomplete', 'Autocomplete' attributes no hope.

另外我不明白用地图功能响应"的目的，所以禁用它.

In addition I could not understand the purpose of "response with map functions", so disabled it.

$(document).ready(function () {

myVars.shId = $('#dataVar').attr('sh-data');

///// search ////// http://jsbin.com/xavatajiku/edit?js,output
console.log(myVars.shId);
$('#name-list').autocomplete({

        source: function (request, response) {
            $.ajax({
                url: myVars.czbUrl,
                data: { searchText: request.term, maxResults: 10, shopId: myVars.shId },
                dataType: "json",
                success: function (data) {
                    console.log(data);
                    /*response($.map(data, function (item) {
                        console.log(data);
                        return {

                            value: item.product_name,
                            avatar: item.pfimage_thumb,
                            rep: item.product_name,
                            selectedId: item.url
                        };
                    }))*/
                }
            })
        },
        select: function (event, ui) {

                             alert(ui.item ? ("You picked '" + ui.item.label)
                                                      : "Nothing selected, input was " + this.value);

            return false;
        }
    }).autocomplete( "instance" )._renderItem = function (ul, item) {
        console.log('test');
        /*var inner_html = '<a><div class="list_item_container"><div class="image"><img src="' + item.pfimage_thumb + '"></div><div class="label"><h3> Reputation:  ' + item.volume + '</h3></div><div class="description">' + item.product_name + '</div></div></a><hr/>';
        return $("<li></li>")
                .data("ui-autocomplete-item", item)
                .append(inner_html)
                .appendTo(ul);*/
    };

推荐答案

一些小的更正，你应该可以开始了:

A few small corrections and you should be on your way:

示例:https://jsfiddle.net/Twisty/3gm3sfem/

JavaScript

$(function() {
  var myData = [{
    product_name: "Name 1",
    pfimage_thumb: "thumb1.jpg",
    url: "url1"
  }, {
    product_name: "Name 2",
    pfimage_thumb: "thumb2.jpg",
    url: "url2"
  }, {
    product_name: "Name 3",
    pfimage_thumb: "thumb3.jpg",
    url: "url3"
  }];
  $('#name-list').autocomplete({
    source: function(request, response) {
      $.ajax({
        url: "/echo/json/",
        data: {
          json: JSON.stringify(myData)
        },
        dataType: "json",
        type: "POST",
        success: function(data) {
          console.log(data);
          response(data);
        }
      })
    },
    select: function(event, ui) {
      alert(ui.item ? ("You picked '" + ui.item.label) : "Nothing selected, input was " + this.value);
      return false;
    }
  }).autocomplete("instance")._renderItem = function(ul, item) {
    console.log('test');
    var item = $('<div class="list_item_container"><div class="image"><img src="' + item.pfimage_thumb + '"></div><div class="label"><h3> Reputation:  ' + item.volume + '</h3></div><div class="description">' + item.product_name + '</div></div>')
    return $("<li>").append(item).appendTo(ul);
  };
});

如果您的数据返回，请将其传递给 response() 以确保菜单得到呈现.你不需要 因为 select 会以任何一种方式被触发.

If your data is coming back, pass it to response() to ensure that the menmu get rendered. You do not need <a> since select will be fired either way.
