Question

How to Access a Web Service in ASP.NET and jQuery from any directory without worrying about localhost or production environment?

Trying to get this jQuery call to function properly on both the localhost and production server has been a challenge. The code resides in a master page, with calls originating from different locations within the file structure. Any assistance would be greatly appreciated.

        function getInternetLeadsCount() {
            $.ajax({
                type: "POST",
                url: "http://localhost:64558/mysite.com/Web_Services/AjaxWebService.asmx/HelloWorld",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: "{}",
                success: AjaxSucceeded,
                error: AjaxError
            });
        }

        function AjaxSucceeded(data, status) {
            alert('jQuery: ' + data.d);
        }

        function AjaxError(x, y, z) {
            alert(x + ' ' + y + ' ' + z);
        }

One way to create a web method in your ASPX page is by using the following code.

$.ajax({
  type: "POST",
  url: "defaul.aspx/HelloWorld",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
alert(msg.d);
  }
});

Alternatively, you can also use the absolute path like this:

$.ajax({
  type: "POST",
  contentType: "application/json; charset=utf-8",
  url: "WebService.asmx/HelloWorld",
  data: "{}",
  dataType: "json"
});

To start off, my recommendation would be to install IIS or IIS Express on your local machine instead of relying on the default Visual Studio server. It's important to develop in an environment that closely mirrors your production server to avoid any potential issues, as you've experienced.

Additionally, I suggest utilizing C# to generate a JavaScript variable that holds the true web root. This can be done in your master page or aspx file:

<script type="text/javascript">
    var webRoot = '<%= Page.ResolveUrl("~/") %>';
    console.log(webRoot); // '/mysite.com'
</script>

By setting webRoot='/mysite.com' on your local machine and webRoot='/' in production, you can then use this JavaScript variable to construct application-relative paths for your web service.

<script type="text/javascript">
    var url = webRoot + '/Web_Services/AjaxWebService.asmx/HelloWorld'
    console.log(url); // '/mysite.com/Web_Services/AjaxWebService.asmx/HelloWorld'
</script>
