User-939850651 postedHi rani_shah19,
According to your description, I created a simpe demo, you could refer to it:
<head runat="server">
<title></title>
<script src="Scripts/jquery-3.4.1.min.js"></script>
<script>
$(function () {
$('#UpdateBtn').on('click', function () {
$.ajax({
url: 'WebService1.asmx/UpdateDataBase',
type: 'post',
contentType: 'application/json,charset=UTF-8',
data: {},
dataType: 'xml',
success: function (responseData) {
var result = responseData.getElementsByTagName("string")[0].childNodes[0].nodeValue;
if (result == "ok") {
console.log('update successfully!')
} else {
console.log('update failed...')
}
},
error: function (e) {
alert("something wrong.");
}
})
})
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="button" id="UpdateBtn" value="Update" />
</div>
</form>
</body>
<System.Web.Script.Services.ScriptService()>
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)>
<ToolboxItem(False)>
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()>
Public Function UpdateDataBase() As String
Try
'Code about update database
'Update successfully then return result
Return "ok"
Catch ex As Exception
'get exception then return result
Return "failed"
End Try
End Function
End Class
But the part of updating the database needs to be coded appropriately according to your own situation.
For more details ,you could refer to the use of .asmx web service.
If I misunderstood anything, please describe more details about your problem.
Best regards,
Xudong Peng
