我有两个组合框。我需要在combobox1更改值并将此值放入Combobox2路径后从第一个combobox1获取一些值
databinding.Ajax()选择。( “行动”, “控制器”, - >路线<< - )
@(Html.Telerik()
.ComboBoxFor(m => m.Country)
.ClientEvents(e => e.OnChange"onCountryChange"))
.BindTo(Model.ListCountry))
@(Html.Telerik()
.ComboBoxFor(m => m.UnitOfAdministration)
.ClientEvents(e => e.OnChange("onCityChange"))
.BindTo(Model.ListUnitOfAdministration)
.DataBinding(bind =>
bind.Ajax().Select("GetCityListByStr", "User",new { idCountry = "in this place i need put curent country ID" })
.Delay(1000))
function onCountryChange(e) {
var fildUnit = $("#fild_UnitOfAdministration");
var fildStreet = $("#fild_Street").hide();
var fildHouse = $("#fild_House").hide();
var fildSegmentHouse = $("#fild_SegmentHouse").hide();
var curCountry = Number(e.value);
if(curCountry.toString() == "NaN" || curCountry==0){
fildUnit.hide();
}else{
$.post("@(Url.Action("GetCityList", "User"))", { id:curCountry, asd:Math.random() },
function (data) {
fildUnit.show();
var comboBox = $('#UnitOfAdministration').data('tComboBox');
comboBox.dataBind(data);
comboBox.select(0);
});
}
}
[HttpPost]
public ActionResult GetCityList(string id)
{
int _id = id.ExtractID();
ViewData["curCountry"] = _id;
List<SelectListItem> listSel = new List<SelectListItem>();
listSel.Add(new SelectListItem() { Text = "Виберіть місто", Value = "0", Selected = true });
TUnitOfAdministration un = TUnitOfAdministration.GetObject(_id);
if (un != null)
{
string sql = "lft>" + un.Lft + " AND RGT<" + un.Rgt + " AND TypeUnit in (2,3) order by Name";
TypedBindingList list = TUnitOfAdministration.GetObjects(sql);
foreach (TUnitOfAdministration item in list)
{
listSel.Add(new SelectListItem { Text = item.Name, Value = item.ID.ToString() });
}
}
return new JsonResult { Data = new SelectList(listSel, "Value", "Text", 0) };
}
[HttpPost]
public ActionResult GetCityListByStr(string text,string idCountry)
{
text = text.ClearStringFull();
int _idCountry = idCountry.ExtractID();
List<SelectListItem> listSel = new List<SelectListItem>();
TypedBindingList list = new TypedBindingList(typeof(TUnitOfAdministration));
listSel.Add(new SelectListItem() { Text = "Виберіть місто", Value = "0", Selected = true });
TUnitOfAdministration country = TUnitOfAdministration.GetObject(_idCountry);
if (country != null)
{
string sqlAll = "ID_UnitOfAdministration = " + country.ID_UnitOfAdministration + " AND Name like '" + text + "%' Order by name";
list = TUnitOfAdministration.GetObjects(sqlAll);
//if (list.Count == 0)
//{
// string sql = "lft>" + country.Lft + " AND RGT<" + country.Rgt + " AND TypeUnit in (2,3) order by Name";
// list = TUnitOfAdministration.GetObjects(sql);
//}
foreach (TUnitOfAdministration item in list)
{
listSel.Add(new SelectListItem { Text = item.Name, Value = item.ID.ToString() });
}
}
return new JsonResult { Data = new SelectList(listSel, "Value", "Text", 0) };
}
提前致谢。
答案 0 :(得分:1)
你可以从当前的RouteData中获取它:
new { curentCountry = ViewContext.RouteData.Values["countryID"] }
其中countryID
是您正在使用的路由参数的名称。或者,如果它是查询字符串的一部分而不是您的路线的一部分:
new { curentCountry = Request["countryID"] }

您可以查看documentation,其中说明了如何订阅在获取数据请求时引发的OnDataBinding
事件:
所以你可以订阅OnDataBinding
事件:
@(Html.Telerik()
.ComboBoxFor(m => m.UnitOfAdministration)
.ClientEvents(e => e.OnDataBinding("onComboBoxDataBinding"))
.BindTo(Model.ListUnitOfAdministration)
.DataBinding(bind => bind.Ajax().Select("GetCityListByStr", "User")
.Delay(1000)
)
允许您将其他参数传递给此请求
<script type="text/javascript">
function onComboBoxDataBinding(e) {
e.data = $.extend({ }, e.data, { curentCountry: "customValue"});
}
</script>
