Sharing variables between 2 separate scripts [duplicate]

阅读更多关于 Sharing variables between 2 separate scripts [duplicate]

问题 This question already has an answer here : Get 2 userscripts to interact with each other? (1 answer) Closed 2 years ago . I'm trying to share variable between 2 different Tampermonkey scripts running in 2 separate tabs. I tried using GM_setValue in one script then retrieving it with GM_getValue in the other one but without any success, so I assume there's separate storage for each script. Is there any easy way to do this? Am I just missing something simple? Can I somehow make both scripts

GM_openInTab (or any other GM_ function) is not defined?

阅读更多关于 GM_openInTab (or any other GM_ function) is not defined?

问题 When my GM script does this: var curTab = GM_openInTab(url); it results in a 'GM_openInTab is not defined' JavaScript error in the Browser Console. I also tried using var curWin = window.open(url); instead of GM_openInTab but it had no affect. What I'm trying to do with this GM script is: for a given website (domain name), go through a list (array) of URLs on this domain and look for items of interest. What's wrong with my code or approach? I'm using Greasemonkey 2.3 with Firefox 33.1.1 and

window.close and self.close do not close the window in Chrome

阅读更多关于 window.close and self.close do not close the window in Chrome

问题 The issue is that when I invoke window.close() or self.close() it doesn't close the window. Now there seems to be a belief that in Chrome you can't close by script any window that is not script created. That is patently false but regardless it is supposed to still do it, even if it requires to pop up an alert to confirm. These are not happening. So does anyone have real, functional and proven method of closing a window using something like javascript:window.close() or javascript:self.close()

问题 I am creating a Greasemonkey/Tampermonkey script that puts some stats into an array. Using JavaScript, how would I make it so a page loads a URL (football.fantasysports.yahoo.com/f1/326198/pointsagainst?pos=QB) in the background and creates an array with the first two columns ( Rank and Team )? The problem I am having is doing all of this in the background, I presume I would be using AJAX. Any help would be appreciated. 回答1: For a static page (like the one you linked), use GM_xmlhttpRequest()

问题 I Asked a question earlier and was given a Working solution. One thing I want to do is incorporate jQuery to remove a class F-link-secondary and replace it with F-rank-good/bad/neutral depending on the value of deltaText. On most pages this is what I see: But on a certain page, the F-rank-XXX class is not there and instead there is just a single F-link-secondary which has no style. Here is what I want to do but I am not sure how to incorporate it with the Greasemonkey script. function getRank

问题 In my Fantasy football page, it gives stats about the opposing team and when you mouseover it tells you how many points they give up (See picture).
