如何在 JavaScript 中发送 XML 请求

Question

I have an eye tracker (mirametrix) running as a server in localhost. In order to capture data from this I should send a xml request as given below;

SEND:<GET ID="TIME_TICK_FREQUENCY" />

I have a web-app running as the client and I need to make a request to this server through that. I wrote the following code but it doesn't seem to send the request properly to the server.

var request = $.ajax({
            url: "http://127.0.0.1:4242",
            type: "GET",
            dataType: "xml",
            data: { 
                data:'<GET ID="TIME_TICK_FREQUENCY" />'

            },

        });

Can someone please help me with this ?

Thanks in advance

Answer 1

$.ajax({
    url: ajaxurl,
    data: "<root><blah><blah></root>", 
    type: 'POST',
    contentType: "text/xml",
    dataType: "text",
    success : parse,
    error : function (xhr, ajaxOptions, thrownError){  
        console.log(xhr.status);          
        console.log(thrownError);
    } 
}); 

I think you need to post it.

this is not plain javascript.. looks more like jquery.. also what do you mean with 'properly'. It's kind sending it, but not really? Aside from that, I see the following problems

• The url is wrong, and although your browser may handle it, your url should end with a slash.
• Your xml is invalid. Needs to start with <?xml version="1.0"?> .
• If you accessed this script through a different host than 127.0.0.1., or if the script is running on a different port than 4242, this will not work without CORS headers on the server.
