我不能爲我的生活弄清楚爲什麼這個ajax調用會一直返回一個錯誤。 (我是新來的網絡世界,所以我猜我錯過了簡單的東西在這裏:S)Ajax調用總是從mvc動作返回錯誤,即使它工作正常
在我的cshtml我有一個Select2多值選擇框持有標籤。
$(function() {
$('#tagSelector').select2({
placeholder: 'Select a tag...',
multiple: true,
ajax: {
url: '@Url.Action("SearchTags", "UnitDetails")',
dataType: 'json',
data: function (term, page) {
return {
searchTerm: term
};
},
results: function (data, page) {
return { results: data };
}
},
createSearchChoice: function (term) {
return {id: term, text: term};
}
}).on("removed", function(e) {
var url = '@Url.Content("~/UnitDetails/UnTagUnit/" + Model.ViewUnitContract.Id)';
var id = e.val;
var tagName = e.choice.text;
console.log(id + " : " + tagName);
$.ajax({
url: url,
data: { selectedItem: tagName },
type: 'GET',
dataType: 'json',
success: function() {
toastr.options = {
"closeButton": true,
"debug": false,
"positionClass": "toast-top-right",
"onclick": null,
"showDuration": "300",
"hideDuration": "1000",
"timeOut": "3000",
"extendedTimeOut": "1000",
"showEasing": "swing",
"hideEasing": "linear",
"showMethod": "fadeIn",
"hideMethod": "fadeOut"
};
toastr.success("Tag deleted from unit.", "Success!");
},
error: function() {
toastr.options = {
"closeButton": true,
"debug": false,
"positionClass": "toast-top-right",
"onclick": null,
"showDuration": "300",
"hideDuration": "1000",
"timeOut": "3000",
"extendedTimeOut": "1000",
"showEasing": "swing",
"hideEasing": "linear",
"showMethod": "fadeIn",
"hideMethod": "fadeOut"
};
toastr.error("Could not delete tag from unit.", "Oops!");
}
});
});
在我的控制器中,UnTagUnit(int id, string selectedItem)
看起來是這樣的:
[HttpGet]
public JsonResult UnTagUnit(int id, string selectedItem)
{
try
{
UnitClient.UnTagUnit(id, selectedItem);
// what to return if success?
}
catch (Exception e)
{
// Log and handle
// what to return if error?
}
}
如前所述,該方法正常工作,我的意思是完成UnTagUnit(id, selectedItem)
部分成功(wcf服務)。
所以,我想我要麼錯過了某些東西,要麼做了根本性的錯誤。還嘗試了不同的方法sucs返回new Json(new { success = true})
。
謝謝你,這麼多! :) –
