下面是我在Visual Studio代码中的html表单:

Carservice.js-从属下拉菜单的javascript文件:
var $select1 = $( '#select1' ),
$select2 = $( '#select2' ),
$options = $select2.find('option');
$select1.on( 'change', function() {
var selectedStateText = $(this).find("option:selected").text();
$select2.html($options.filter('[value="' +this.value + '"]') );
}).trigger('change');
$select2.on( 'change', function() {
var selectedCityText = $(this).find("option:selected").text();
});
Formtoapi.js:将表单发布到Visual Studio 2022中的Web-API:
document.getElementById("myForm").addEventListener("submit",submitForm);
function submitForm(event){
event.preventDefault();
var formData=new FormData(event.target);
fetch("http://localhost:5239/api/Forms/submit-form",{
mode:"cors",
method:"POST",
body:formData
})
.then(response =>{
if(!response.ok){
throw new Error("HTTP error"+respsonse.status);
}
return response.json();
})
.then(data=>{
console.log("Success:",data);
})
.catch(error=>{
console.error("Error:",error);
});
}
在API中，我得到了一个控制器 FormsController.cs:
using CarFormApi.Models;
using Microsoft.AspNetCore.Cors;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
namespace CarFormApi.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class FormsController : ControllerBase
{
private static List<FormsDataModel> formsDataList = new List<FormsDataModel>();
[HttpPost("submit-form")]
public IActionResult SubmitForm([FromForm] FormsDataModel formsData)
{
// process the form data
string carmodel = formsData.Carmodel;
string carnum = formsData.Carnum;
string contactnum = formsData.Contactnum;
string typeofservice = formsData.Typeofservice;
string selectstate = formsData.Selectstate;
string selectcity = formsData.Selectcity;
// validate the form data
if (string.IsNullOrWhiteSpace(carmodel) || string.IsNullOrWhiteSpace(carnum) || string.IsNullOrWhiteSpace(contactnum) || string.IsNullOrWhiteSpace(typeofservice) || string.IsNullOrWhiteSpace(selectstate) || string.IsNullOrWhiteSpace(selectcity))
{
return BadRequest(new { Message = " Enter the required fields." });
}
formsDataList.Add(formsData);
return Ok(formsData);
}
}
}
还创建了一个FormsDataModel:
namespace CarFormApi.Models
{
public class FormsDataModel
{
public string Carmodel { get; set; }
public string Carnum { get; set; }
public string Contactnum { get; set; }
public string Typeofservice { get; set; }
public string Checkk { get; set; }
public string Selectstate { get; set; }
public string Selectcity { get; set; }
}
}
除了那些下拉菜单之外，一切都运行得很好.我的html表单的输入值正在回发到控制台.是的，我可以看到所选选项的值被张贴，但不能看到所选选项的实际名称/标签.我希望在控制台中显示选项(如"卡纳塔克邦")而不是值(如"option1").
谁能告诉我怎么才能做到这一点，请帮助我明白我做错了什么.
