Javascript – How to pass data to parent window from popup window

javascriptjquerypopup

How can I pass some data or call a function on the parent window from a popup window?

The user will click a link which will open a popup on the same website, once he is finished with the popup, I want it to send the new data back to the parent window, or call a function on the parent window.

The window.opener object is what you're looking for, used it from within your popup like so to call the a function of the parent window:

window.opener.yourFunc()

setInterval() returns an interval ID, which you can pass to clearInterval():

var refreshIntervalId = setInterval(fname, 10000);

/* later */
clearInterval(refreshIntervalId);

See the docs for setInterval() and clearInterval().

eval() is not necessary. This will work fine:

var date = new Date(parseInt(jsonDate.substr(6)));

The substr() function takes out the /Date( part, and the parseInt() function gets the integer and ignores the )/ at the end. The resulting number is passed into the Date constructor.

I have intentionally left out the radix (the 2nd argument to parseInt); see my comment below.

Also, I completely agree with Rory's comment: ISO-8601 dates are preferred over this old format - so this format generally shouldn't be used for new development.

For ISO-8601 formatted JSON dates, just pass the string into the Date constructor:

var date = new Date(jsonDate); //no ugly parsing needed; full timezone support
