greasemonkey

问题 I'm creating a UserScript extension for Firefox & Chrome and I'm trying to use some of the code in the website's JavaScript, e.g.: function: myFunction(){ return Grooveshark.playNextSong(); } The problem is when I test this code, Grooveshark is a null reference. I know there are other people who have done it: see BetterGrooveshark But I don't know why my simple extension can't call Grooveshark's JavaScript functions. Do I need to 'append' my script to the document in order for this to work?:

问题 I'm doing a Greasemonkey script that communicates with the Redmine ticket manager through the REST API. As the user needs to login to get the data from Redmine, I need a way to ask the user for his credentials at script installation and save them to the script. Can this be achieved without asking the user to edit the values directly in the script itself? EDIT: Since there is already an answer to this question I will validate the answer given just below as it is a very good framework. 回答1:

问题 Can, for example, Facebook.com run a version control script on my browser and find out if I am running altered HTML code with the use of a script? Could that be done with a script that can read the HTML code in the cache and produce some kind of hash tag that is sent back to the server and compared with the code that was sent to the client? 回答1: Yes, in theory, a site can deduce the presence of scripts in various situations. This is not foolproof and usually is way too much trouble for the

问题 I have a Greasemonkey script that works just fine in Firefox and Opera. I struggle with getting it to work in Chrome, however. The problem is injecting a function into the page that can be invoked by code from the page. Here's what I'm doing so far: First, I get a helper reference to the unsafeWindow for Firefox. This allows me to have the same code for FF and Opera (and Chrome, I thought). var uw = (this.unsafeWindow) ? this.unsafeWindow : window; Next, I inject a function into the page. It

问题 I need to have a function execute on a page in one tab when certain conditions are met in another tab. All I need to do is send some kind of nudge to the other tab. I've tried many things already in conjunction with a timer to keep polling: GM_setValue (not supported in Chrome apparently) Setting top.item (apparently doesn't work between tabs) Cookies (even though my userscripts are running in two tabs on the same domain, this doesn't seem to work) Any other ideas? And yes, I do need to use

问题 I'm looking for a way to automatically fill in a username/password in a webpage using Greasemonkey. The two tags are inputs, they have no ID but they're the only two inputs in the page, which appear when a 'log in' button is pressed. I am a beginner in Greasemonkey (and javascript) and I was wondering how I could wait for these two inputs to appear. Then there's two buttons, an 'ok' and a 'cancel' button. The 'ok' button is greyed, and setting the inputs with element0.value="password" doesn't

问题 I am using Selenium to test a web application and am not allowed to modify the application's javascript code. I am trying to track the number of outstanding AJAX requests by using GreaseMonkey to override XMLHttpRequest.send. The new send() will basically wrap what was set as the onreadystatechange callback, check the readyState, incrementing or decrementing the counter as appropriate, and calling the original callback function. The problem that I'm having appears to be a privilege issue

问题 Nothing I've tried seems to work. I found these two links and thought they'd be helpful, but that hasn't worked either. Dynamically load JavaScript with JavaScript https://developers.google.com/loader/ Here's roughly what my Greasemonkey script looks like currently: var init_map = function() { new google.maps.Geocoder().geocode({address:'1125 NW 12th Ave, Portland, OR'},function(result){ alert(result); }); } function loadMaps() { GM_log("loadMaps called"); google.load("maps", "3", {"callback"
