Hi,

A security feature in modern web browsers means that JavaScript can only be used to access external pages if they have permission to do so, through setting the "Access-Control-Allow-Origin" header. This is to prevent users from maliciously using JavaScript to carry out an action on another website, without the user's consent.

For example, if I had a page on "website1.x10.mx", that connected to "website2.x10.mx" through JavaScript alone, I would need to set an Access-Control-Allow-Origin header on "website2.x10.mx" of "website1.x10.mx", so it has permission to retrieve data.

Therefore, you can solve this problem by either having your external PHP script serve the "Access-Control-Allow-Origin" header, or you could retrieve the data using PHP instead.

Thank you,
