Jquery 在选择建议字段的值后，是否有方法填充输入字段？

我在一个销售系统的asp.net核心的web应用程序（MVC）中工作

在我的销售订单创建中，我有一个字段，当用户开始键入时，该字段建议要选择的文本。问题是：我需要当用户选择一个文本时，与该信息相关的其他字段会自动完成

我试着实现我的控制器和视图（如下所示），但我唯一能做的就是在不填写客户名称的情况下实现建议字段“searchCNPJ”

控制器

public IActionResult AutoComplete_Cliente()
{
      var name = HttpContext.Request.Query["term"].ToString();
      var cnpj = _context.Juridicos.Where(pf => pf.CNPJ.Contains(name)).Select(pj => pj.CNPJ).ToList();

      return Ok(cnpj);
}

看法

下面是一个简单的演示，如下所示：

1.型号：

public class Test
{
    public int Id { get; set; }
    public string CNPJCLIENTE { get; set; }
    public string NOMECLIENTE { get; set; }
}

2.意见：

<div class="form-row mt-2">
    <div class="col col1 col-sm-3 disabled">
        <label class="control-label">CNPJ/CPF CLIENTE</label>                
        <input id="searchCNPJ" type="text" name="value" class="form-control" placeholder="" />
    </div>
    <div class="col col3 col-sm-9">
        <label class="control-label">NOME CLIENTE</label>
        <input id="nomeCliente" class="form-control disabled" />
    </div>
</div>

    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
    <script>
        $(function () {          
            $("#searchCNPJ").autocomplete({
                source: '/Home/Test'              
            });
        });          
        $('#searchCNPJ').on('autocompletechange change', function () {
            var data = this.value;
                $.ajax({
                    type: "Get",
                    url: "/Home/Test2?name="+data,
                    success: function (data) {
                        console.log(data);
                        $('#nomeCliente').val(data);
                    }
               })                     
             }).change();
    </script>
}

4.结果（当您键入一封信时，它会给您提供建议。然后您选择一个项目并单击任意位置以触发更改事件）：

谢谢！正是我需要的。
