html，javascript-弹出窗口

i have popup-window in my script. I use window.open, but almost all browsers block this kind of windows. So i wanna change it to another popup, which include php-script. I saw it at another sites. As i understand, they use ajax. Could you provide for me some more info?

Try out the solution provided by thickbox, I think this is what you're looking for.

First, you create a div (or other element) with the aspect you want, adding it the following extra CSS:

#popup {
  display: none;
  position: absolute;
  top: 100px; // changeable
  left: 100px; // changeable
}

Then you use JavaScript to change the CSS making the div visible, and add the XHTML response from AJAX to its innerHTML.

I'd recommend using jQuery or other easy-to-use framework if you're used to JavaScript / AJAX.
