I want to send a JSON object to a PHP file while my script opens that PHP file in a new popup window. Is it possible to send it via POST method (by jQuery or without it)?
If not, how do I convert JSON to a URL encoded string? Is there any JavaScript function?
You may create a form (on the fly) with an input (where you fill the value with the JSON) and a target-attribute regarding to name of the popup (second parameter of
window.open()).Then send this form.
