simple HttpRequests

RunBasic passes a JavaScript HttpRequest object as part of its operation.

Because this JavaScript code is in your HTML page you are free to make calls against it.

Here is a small demo that utilizes that code.
To use call the function:
AjaxLiveUpdate(url,id)
url - the document or image you want to load.
id - The html ID of a div to show this data.

benjamin805 has an article on the Wiki on HttpRequests and a demo.

This code utilizes the existing JavaScript thats loaded to the page.

head "<script type = 'text/javascript'> 
 
 function AjaxLiveUpdate(url,id)
 {
 var initialized = newHttpRequest()
 if (initialized)
 {
 var obj = document.getElementById(id);
 initialized.open('GET', url);

 initialized.onreadystatechange = function()
 {
 if (initialized.readyState == 4 && initialized.status == 200)
 {

 // obj.innerHTML = initialized.responseText;
 obj.innerHTML = ""<img src =""+url+"">"";
 }
 }
 initialized.send(null);
 }
 }
</script>"

html "</div>
<div id = 'test'>This space reserved for Pie Chart</div>
<br/>
<input type = 'button' value = 'LiveUpdate' onclick =AjaxLiveUpdate('/chart.png','test');>"
