XMLHttpRequest
对象(或基于COM的brother):
function getJSON()
{
var xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
xhr.open("GET", "http://mysite.com/myscript.asp", true);
xhr.onreadystatechange = function ()
{
if (xhr.status == 200 && xhr.readystate == 4)
{
if (JSON) // provided by json2.js or browsers with native JSON
var result = JSON.parse(xhr.responseText);
else
var result = eval ('(' + xhr.responseText + ')');
// Do something with the result here
}
}
xhr.send();
}
