I want to have a bookmark on my browser (Firefox 3 or Chrome preferably) that is only a snippet of JavaScript code. It would construct a URL based on the current date and then do a window.location = on that URL.
I know that I could make a page and keep it on my local machine and just refer to it that way, but I was wondering if you could bypass that step and actually have the location of the bookmark really just be JavaScript. I could have sworn that this was possible years ago, but I can't find anything that tells me either way now.
You can do that by adding this to your favorites:
javascript:(function(){document.location.href="http://stackoverflow.com";})()
The correct name for this kind of bookmarks is favelets. For some more inspiration check out this collection of favelets.
Use as your bookmark’s address javascript:window.location='https://www.google.com/search?q='+Date();
to create a bookmarklet that searches Google for the current date and time.

I am looking for a way to fool a web page, more precisely a js module in spanking it to believe that it is on another domain name. I documented myself and I came across pkusieur forum which spoke of overwrite the variable window.location.hostname. I unfortunately did not find any answer to my question. Did I orient myself well? Can somebody solve my problem?
Thank you in advance.
EDIT
I can use explorer like firfox or chrome or use a spécifique python module for create a appilcation can do this.
You can directly change window.location.hostname, however doing so will cause the browser to actually navigate to the new URL.
You can't have window.location reflect a value that isn't the actual location of the browser.
Modifying window.location.xy results in page-reload:
console.log(window.location.hostname);
console.log(window.location.hostname="example.com");
console.log(window.location.hostname);
(In the JS console you can see that the value remains unchanged for the snippet itself, but then the page reloads from example.com)
My goal is not to redirect but I want to stay on www.example.com but the js import code is veiled www.fakeSite.com #tevemadar.
I think you would need to change origin for that, and it is the only read-only part of Location exactly for making that impossible. You want to circumvent CORS to my understanding.
I do not suggest using it, but if you desperately need some hack to test something, check https://cors-anywhere.herokuapp.com/
I'm trying to make a Bookmarklet to grab an id value from the Clipboard, and navigate to a URL that is built with that id.
javascript:(function(){
window.location="index.php?module=Accounts&action=DetailView&record="
+ clipboardData.getData('Text');
})()
(this is only supposed to work when clicked on a specific site that is expecting that URL form)
The basics of the Bookmarklet are working fine, the tricky part is getting the Clipboard value, because clipboardData is not working.
I am using Firefox v64 (although I would like this to be generic across more browsers, at least modern ones).
Now, upon searching about this issue I realize what I'm trying to do is not as simple as it seems - clipboard API's in browsers are a tricky issue. I found several answers about this, the best one seems to be this:
JavaScript get clipboard data on paste event (Cross browser)
I also tried this one but couldn't get it to work either: https://stackoverflow.com/a/27908501/1189711
My question here is: are any of those techniques applicable in a Bookmarklet? If so, I would appreciate some help with this. My skills in Javascript are too low to understand how to translate these answers to my case - namely the asynchronous stuff.
PS - if someone wants a place to test this, just put 84f1bb99-7017-e8dc-94f9-5c179da9f102 in your clipboard and try it on this demo site, credentials will/will.
Clipboard copy cannot works from scripts. It must comes from an user action.
Similary, in the same way, you can't call a fullscreen from a bookmarklet.
From the Firefox console:
document.execCommand(‘cut’/‘copy’) was denied because it was not
called from inside a short running user-generated event handler.
I try this method and it works:
SAME WINDOWS:
javascript:location.href='https://www.ricerca.com?search%27+escape(location.href)
NEW WINDOWS: (by https://9to5answer.com/window-location-href-and-window-open-methods-in-javascript)
window.open()
javascript:window.open("https://www.ricerca.com?search="+window.getSelection());
I'm trying to set the value of a textarea on the following page by executing something similar the below javascript:
javascript:alert(document.getElementsByClassName('uiTextareaNoResize uiTextareaAutogrow _1rv DOMControl_placeholder')[0].value='blabla');
This works if I manually enter the code into the address bar on the target page, but I want to pass this argument through a link.. ie...
<a href="/nextpage.php?javascript:alert(document.getElementsByClassName('uiTextareaNoResize uiTextareaAutogrow _1rv DOMControl_placeholder')[0].value='blabla');"
Just wondered if anything like this is possible at all?
You can send the arguments via the url like you would for GET requests. Then have the receiving page parse location.search.
For instance, you can send it like this:
http://example.com/?arg1=foo&arg2=bar
And the receiving page have a script like this:
var queryString = location.search; //?arg1=foo&arg2=bar
You'll have to parse it manually though, removing the ?, split by & then each by =
This is called XSS or Cross-Site-Scripting, and as many comments have already pointed out, it is a security issue. This is why most major browsers do NOT allow it.
However, I believe that some browsers do allow it, for example Opera - although I can't recall exactly which version.
If you are looking to make your own "browser", I would recommend using C# .Net WebBrowser, then use the runtime package XULRunner (https://developer.mozilla.org/en-US/docs/Mozilla/Projects/XULRunner).
Despite all this, I would not recommend doing anything that may be against laws of your current location, or doing anything to displease the site owner.
I want to improve an existing website (I have no access to) by using my own javascript.
This means I have to add an < script > to the < head >. I am currently doing this by clicking on a bookmark which has something like this as its target:
javascript: if(document.createElement){
void(head=document.getElementsByTagName('head').item(0));
void(script=document.createElement('script'));
void(script.src='http://local/script.js');
void(script.type='text/javascript');
void(head.appendChild(script));
} // i added some spacer to make it readable
This works fine, but since i've got a lot of different scripts it gets complicated to organize them.
I am now looking for a way to automatically insert a defined script-uri if the top.location.href matches a given string.
Is there a way firefox can do something like this - maybe with the help of an add-on?
Userscripts are what you're looking for. Use Greasemonkey for Firefox to run your own script on specific sites.
https://addons.mozilla.org/en-US/developers/docs/sdk/1.12/modules/sdk/page-mod.html uses the add-on sdk, and provides precisely what you're looking for (i.e. an easy way to attach a script to a webpage if it matches a given domain). That gives you the option of making your addon a standalone one easily; moreover, if you were to extend its functionality significantly, the addon sdk would certainly be the way to go!
I'm thinking that the reason I can't do this is because it might be a huge security hole, but here goes...
I want to have a bookmark on my browser (FF3, preferably) that is only a snippet of javascript code. It would merely construct a URL based on the current date and then do a window.location = on that URL.
I know that I could make a page and keep it on my local machine and just refer to it that way, but I was just wondering if you could bypass that step and actually have the "location" of the bookmark really just be javascript. I could have sworn that this was possible years ago, but I can't find anything that tells me either way now.
What you want is a bookmarklet they are easy to create and should work in most major browsers.
Edit: Stack overflow seems not to allow creating bookmarklets in the context of the site, basically you can create a new bookmark and type the following in the location field
javascript:window.location='http://www.google.com/search?q='+Date()
to get a bookmarklet that searches google for the current date.
It is worthy of note that you can put that in a function wrapper as well. imranamajeed nicely illustrated that for us... but apparently I'm too new to the site to up his post. :P
so for clarity:
javascript:(function(){
location.href = location.href + "#";
})();
(the carriage returns did not affect performance in chrome and IE)
One minor catch. IE can only handle a 508 character URL in this format. If you save it in IE with a url longer than this, it will truncate without warning and thus fail.
If you need a really complex script, you'll need to use a "hosted" bookmarklet, where you have a short bookmark that injects a script tag into the page, to "call" your hosted bookmarklet.
It isn't as nice/portable, but its the only workaround.
Google Bookmark
javascript:(function(){var%20a=window,b=document,c=encodeURIComponent,d=a.open("http://www.google.com/bookmarks/mark?op=edit&output=popup&bkmk="+c(b.location)+"&title="+c(b.title),"bkmk_popup","left="+((a.screenX||a.screenLeft)+10)+",top="+((a.screenY||a.screenTop)+10)+",height=420px,width=550px,resizable=1,alwaysRaised=1");a.setTimeout(function(){d.focus()},300)})();
Well, I just created a bookmark in FF3, went back and updated it and added the following test:
javascript:alert('Wacky%20test%20yo');
Low and behold, after I saved and loaded, I was able to get my alert.
I'm sure you can work up something similar for your needs.
