javascript - open window and run function on that window -

i'd open new window, window has list of objects, , these objects should filtered based on selection previous window. figured can filter list through function, how run said function?

this able do:

var popup = window.open('pageurl');     $(popup.document).ready(function() {         // function should         popup.alert('helloworld');     }); 

but how change alert function?

if have function on other app , function test() { alert('helloworld'}; how run function first app?

swapping popup.alert('helloworld'); popup.test(); did not work.

you need reference window opened call functions in new window, like:

var onewwindow = window.open("new.window.url", "mywindow"); onewwindow.onload = function(){onewwindow.window.newwindowfunction();};
