Tips for invoking a URL in an Ajax JSON request

Having trouble calling a webservice from a specific directory within my project.

The URL I'm trying to access is "~/RA/WebServiceRAOpen.asmx/OpenedRAlistByBranch" but it's not functioning as expected.

$.ajax({
     url: "~/RA/WebServiceRAOpen.asmx/OpenedRAlistByBranch",
     data: "{ 'ranumber': '" + request.term + "' }",
     dataType: "json",
     type: "POST",
     contentType: "application/json; charset=utf-8",
})

Any suggestions on how to successfully call the URL from a specific directory?

Answer №1

To construct the URL using the absolute server path, you can utilize window.location in this way:

$.ajax({
   url: window.location.host + "/RA/WebServiceRAOpen.asmx/OpenedRAlistByBranch"
...

A relative URL should also function correctly. Just omit the "~" prefix. Keep in mind that you need to run JavaScript code from a true HTTP server rather than locally. When debugging in Visual Studio, a local HTTP server is used, so that should suffice.

Answer №2

Web addresses that begin with ~/ are specific to ASP.NET. When working with JavaScript, you must convert these addresses to their actual URLs. Extract the path on your webpage and store it in a JavaScript variable for use in your script.

HttpContext.Current.Server.MapPath("~/RA/WebServiceRAOpen.asmx/OpenedRAlistByBranch")
retrieves the real path. It's been a while since I've worked with ASP.NET, so I can't recall the correct syntax for asp:label to guide you further.
