我是 Ajax 的新手,如果在下拉列表中选择了某些项目,我会尝试禁用复选框。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:
这是最终的 javascript 看起来如何工作
// 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);
}
}
});
}
