我是Ajax的新手,正在尝试在下拉菜单中选择某些项目时禁用复选框。 我需要将mlaId传递给RecipientsController.cs中的GetMlaDeliveryType(int Id)方法。
我不确定如何在javascript函数checkMlaDeliveryType(mlaId)中设置ajax调用。
// MLA Add disable express checkbox if delivery type is electronic
$('.AddSelectedMla').change(function () {
var deliveryType = checkMlaDeliveryType($('.AddSelectedMla').val());
// disable express option if delivery type is Electronic
if (deliveryType == "Mail") {
$(".mlaExpressIndicator").removeAttr("disabled");
}else{
$(".mlaExpressIndicator").attr('checked', false).attr("disabled", true);
}
})
// ajax call to get delivery type - "Mail" or "Electronic"
function checkMlaDeliveryType(mlaId)
{
$.ajax({
type: "GET",
url: "/Recipients/GetMlaDeliveryType/" ,
data: mlaId,
dataType: ,
success:
});
}
RecipientsController.cs
public string GetMlaDeliveryType(int Id)
{
var recipientOrchestrator = new RecipientsOrchestrator();
// Returns string "Electronic" or "Mail"
return recipientOrchestrator.GetMlaDeliveryTypeById(Id);
}
编辑:
下面是最终可行的JavaScript代码:
// MLA Add disable express checkbox if delivery type is electronic
$('.AddSelectedMla').change(function () {
checkMlaDeliveryType($('.AddSelectedMla').val());
})
// ajax call to get delivery type - "Mail" or "Electronic"
function checkMlaDeliveryType(mlaId)
{
$.ajax({
type: 'GET',
url: '@Url.Action("GetMlaDeliveryType", "Recipients")',
data: { id: mlaId },
cache: false,
success: function (result) {
// disable express option if delivery type is Electronic
if (result == "Mail") {
$(".mlaExpressIndicator").removeAttr("disabled");
} else {
$(".mlaExpressIndicator").attr('checked', false).attr("disabled", true);
}
}
});
}
