When I use the AJAX directly in a web page, it works.

When I use AJAX inside a plugin, it gives me an error.

Note: When I use the following ajaxSettings from the code of the section (jquery 1.3.x) it worked.

ajaxSettings: {

url: location.href,

global: true,

type: "GET",

contentType: "application/x-www-form-urlencoded",

processData: true,

async: true,

/*

timeout: 0,

data: null,

username: null,

password: null,

*/

Create the request object; Microsoft failed to properly

implement the XMLHttpRequest in IE7, so we use the ActiveXObject when it is available

// This function can be overriden by calling jQuery.ajaxSetup

xhr:function(){

return window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();

},

accepts: {

xml: "application/xml, text/xml",

html: "text/html",

script: "text/javascript, application/javascript",

json: "application/json, text/javascript",

text: "text/plain",

_default: "*/*"

}

},
