我有一个MVC Razor View页面,供人们输入详细信息并提交到数据库。 它使用下拉列表,但我想在表单中添加自动填充文本框。 这工作正常但是当回发到POST控制器时,它总是将人的ID设置为0。有什么想法吗?
由于
使用Javascript:
script type="text/javascript">
$(document).ready(function () {
$("#PersonName").autocomplete({
source: '@Url.Action("AutocompleteSuggestions")',
minLength: 2,
select: function (event, ui) {
if (ui.item) {
$("#PersonName").val(ui.item.label);
$("#PersonId").val(ui.item.value);
}
}
});
});
</script>
控制器:
[HttpPost]
public ActionResult Create(MappingModel view)
{
if (ModelState.IsValid)
{
var entity = new PersonContempancy();
entity.PersonId = view.PersonId;
entity.FrameworkId = view.FrameworkId;
entity.ContempancyCategoryId = view.ContempancyCategoryId;
entity.ContempancyId = view.ContempancyId;
entity.ContempancyLevelId = view.ContempancyLevelId;
entity.FrameworkLevelId = view.FrameworkLevelId;
db.PersonContempancies.Add(entity);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.Contepancies = db.Contempancies.ToList();
ViewBag.ContempancyCategory = db.ContempancyCategories.ToList();
ViewBag.ContempancyLevel = db.ContempancyLevels.ToList();
ViewBag.FrameworkLevel = db.FrameworkLevels.ToList();
ViewBag.Person = db.People.ToList();
ViewBag.Framework = db.Frameworks.ToList();
return View();
}
public ActionResult AutocompleteSuggestions(string term)
{
var namelist = db.People.Where(c => c.PersonName.Contains(term)).Select(c => new { value = c.PersonId, label = c.PersonName}).Distinct().Take(10);
return Json(namelist.ToArray(), JsonRequestBehavior.AllowGet);
}
答案 0 :(得分:0)
查看您的AutoCompleteSuggestions代码,看起来您在返回JSON时只回发了人名,而不是该人的ID。如果我正确理解你需要返回名称和ID,并在自动完成功能的select函数中通过JQuery设置person id。它应该(大致)看起来像这样:
var namelist = (from c in db.People where c.PersonName.Contains(term) select new { c.PersonName, c.PersonID}).Distinct().Take(10).ToArray();
return Json(namelist.ToArray(), JsonRequestBehavior.AllowGet);
和
$("#searchTerm").val(ui.item.value.PersonName);
$("#PersonID").val(ui.item.value.PersonID);
