我有一个 jQuery Ajax WebMethod 调用,如下所示:
<script type="text/javascript">
$(document).ready(function () {
$("#btnsubmit").click(function () {
var arr = new Array();
arr.push($("#control1").val()); arr.push($("#control2").val()); arr.push($("#control13 option:selected").val()); arr.push($("#control4 option:selected").val()); arr.push($("#control15 option:selected").val());
var requestedData = JSON.stringify(arr);
requestedData = "{'details':'" + requestedData + "'}";
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "EmployeeDemotion.aspx/Save",
data: requestedData,
dataType: "json",
success: function (result) {
//check the value returned from the WebMethod and provide alerts accordingly
},
error: function (result) {
alert("Error");
}
});
});
});
</script>
并且,WebMethod 如下:
[WebMethod(EnableSession = true)]
public static InsertDetails[] Save(string details)
{
DataTable dt = new DataTable(); DataTable dts = new DataTable();
List<InsertDetails> data = new List<InsertDetails>();
JavaScriptSerializer js = new JavaScriptSerializer();
string[] Tags = js.Deserialize<string[]>(details);
object[] obj = new object[8];
obj[0] = Tags[0].ToString(); obj[1] = Tags[1].ToString(); obj[2] = Tags[2].ToString(); obj[3] = Tags[3].ToString();
obj[4] = Tags[4].ToString();
int a = //say condition 1
int b = //say condition 2
if (a< b)
{
//insert into database and set a value which says the insertion has succeeded
}
else
{
//alert that data cannot be inserted
}
return data.ToArray();
}
现在,我需要将任何可能类型(布尔、数组、字符串、整数或其他)的值返回给 ajax 方法,以便 ajax 方法中的成功函数提醒插入状态(如代码段中所述),即;应与最后一条语句“return data.ToArray();”一起返回一个值 到ajax方法。我不需要返回元素“数据”,验证插入的值应该与“数据”一起返回或以任何其他形式返回。
