I'm using web-forms to collect data from a form and then send the data to the code-behind to send to an API. Using a button I'm calling a JavaScript method which collates the data and then sends to my aspx.cs file to send to the API. The Html code for the button is
<button class="search btn" ID="btnSearch" onclick="searchApi(); return false;"><i class="fas fa-search"></i>Search</button>
This runs the searchAPI() function which works and creates a concatenated string called SearchData. The Javascript code looks like this
var searchString = JsonData;
var trimsearchString = searchString.replace(/,/g, '');
$.ajax({
type: "POST",
url: 'Default.aspx/GetApi',
data: searchString,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
alert('success');
},
error: function (errordata) {
console.log(errordata);
alert(errordata);
}
});
The method GetAPI in my Default.aspx.cs file is never called. The method code is
[System.Web.Services.WebMethod]
public static void GetApi(string searchData)
{...
The success: function (data) returns success but the code behind method is never called, can someone please tell me what I am missing.
fix the ajax data, it seems that method with this parameter can' t be found
$.ajax({
type: "POST",
url: 'Default.aspx/GetApi',
data: { searchData: trimsearchString},
//or if it is still problem, you can even try
data: JSON.stringify( { searchData: trimsearchString}),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
alert(data);
},
error: function (errordata) {
console.log(errordata);
alert(errordata);
}
});
and your webmethod should return something
[WebMethod]
public static string GetApi(string searchData)
{
return searchData
}
