jqgrid 編集フォームを使用しようとしていますが、行を選択して編集アイコンをクリックするたびに jqgrid が asmx Web メソッドを呼び出さない理由がわかりません (jqgrid は初めて ajax を呼び出します)。
これはコードです:
function Grid() {
var ret = Array();
var grid = jQuery("#grid");
var hideLoading = function () {
$("#lui_" + grid).hide();
$("#load_" + grid).hide();
}
var strSearch = "";
var strField = "";
var strOper = "";
//
// handler: si occupa di creare il contenuto del menu a tendina (form jqGrid)
//
var buildOptions = function (dataList) {
var response = dataList;
var option = "";
if (response && response.length) {
for (var i = 0, l = response.length; i < l; i++) {
if (response[i]["selectedvalue"] == "on")
option += '<option role="option" selected="selected" value="' + response[i]["Codice"] + '">' + response[i]["Descrizione"] + '</option>';
else
option += '<option role="option" value="' + response[i]["Codice"] + '">' + response[i]["Descrizione"] + '</option>';
}
}
return option;
};
grid.jqGrid({
// setup custom parameter names to pass to server
prmNames: {
search: "isSearch",
nd: null,
rows: "numRows",
page: "page",
sort: "sortField",
order: "sortOrder"
},
// add by default to avoid webmethod parameter conflicts
postData: {
searchString: '',
searchField: '',
searchOper: ''
},
// setup ajax call to webmethod
datatype: function (postdata) {
$.ajax({
url: '<%# ResolveUrl("~/Service/Domain/ServiceRoom.asmx/GetRoomRateDiscount") %>',
type: "POST",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(postdata),
dataType: "json",
success: function (data, st) {
if (data.d == "KO") {
grid.GridUnload();
jAlert("La ricerca non ha restituito alcun risultato", "Book2Guest");
return false;
}
if (st == "success") {
var grid = $("#grid")[0];
grid.addJSONData(JSON.parse(data.d));
ret = JSON.parse(data.d);
}
},
error: function (xhr, textStatus, errorThrown) {
jAlert("Si è verificato un errore: " + textStatus + " " + errorThrown + " -- " + $.parseJSON(xhr.statusText), "Book2Guest");
}
});
},
// this is what jqGrid is looking for in json callback

更新: この問題を解決するには、jqGrid の編集セクションに「recreateForm: true」を挿入する必要があります。
