如何使油膏猴子运行特定的javascript：函数？

Question

Can somebody help me loop the following function and make it run every 5 seconds:

javascript:listAction(
    'editObjectSingle','inforUpdateAction','divEditObjectSingle','formEditObjectSingle'
);

for the specific website google.com?

I'm still new to this and unsure how to write it

// ==UserScript==
// @name           Google
// @description    Google
// @include        Google.com
// ==/UserScript==

// initiate

This is what I have so far, not sure how to add other stuff. Thanks!

For the default @grant setting ( @grant none ), calling a page's javascript is relatively straightforward.

If, and only if, listAction is a global function on the page (it probably is), then you can call it like so:

// ==UserScript==
// @name        Google function spammer
// @match       *://*.google.com/*
// @description Spam the snot out of the listAction function on Google.
// @grant       none
// ==/UserScript==

var updateTimer = setInterval ( function () {
        //-- The function will not always exist (right away).
        if (typeof listAction === "function") {
            listAction (
                'editObjectSingle', 'inforUpdateAction',
                'divEditObjectSingle', 'formEditObjectSingle'
            );
        }
    },
    5 * 1000    // 5 seconds
);

Note that the @include directive in the question is off and the replacement with @match , above.

Also beware that if the function is called from a click handler, etc., it may expect/require a context ( this ). In that case, calling it requires more information than is present in this question and probably can be accomplished by programmatically clicking on the control .
