Re: XMLHTTPRequest

Hi Ted,

Your send() call is asynchronous, meaning you don't receive results immediately. Register onload event listener and wait; you can easily find proper usage patterns in the net.

Also, it is not productive to ask questions without looking at server logs, _javascript_ console and LiveHttpHeaders first. Many things could go wrong with your setup and we would not even know it.

I'm trying to master AJAX.  This is my _javascript_ code:

var Data_Display

var My_Data

function Setup() {

     My_Data = new XMLHttpRequest();

     My_Data.open("GET","http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Data.xq");

My_Data.send();

document.getElementById("Information").value = My_Data.responseXML;

}

This is my XML

<xml>

<svg>

<svg_data>100</svg_data>

</svg>

</xml>

This is my XQuery

xquery version "3.0";

for $Data in doc("Database_Example.xml")/xml/svg/svg_data

where $Data = "">

return $Data

When I open my webpage, nothing appears in the textbox.  Am I doing something wrong?
