  • How can you replace a link's target in Greasemonkey?

    - by Derek
    I'm trying to write a script in Greasemonkey that will replace a link's target with something else, but with my limited Javascript knowledge I don't really know how to do this. Basically I'm trying to find all links containing a certain string of characters (ex: //a[contains(@href, 'xx')] ), and either replace them with another link, or append something to them (replacing 'abc123.com' with 'zyx987.com' or 'abc123.com' with 'abc123.com/folder'). If you could point me on the right path I'd greatly appreciate it.

  • Can I use feature detection to know if css hover works for this client?

    - by user366061
    I've got a website that provides labels when the user hovers over an image. You can see the example at: http://www.185vfx.com/ For touchscreens, I'd like to have those hints on by default (since hover isn't usually available). I'd prefer not to browser-sniff and try to maintain that list as new devices/versions arrive. Any reliable way to detect if a browser can respond to hover or otherwise know about a touchscreen user via javascript or css?

  • Sanity check on this idea for an Image Viewer in a web app

    - by Charlie Flowers
    I have an approach in mind for an image viewer in a web app, and want to get a sanity check and any thoughts you stackoverflowers might have. Here's the whirlwind nutshell summary: I'm working on an ASP.NET MVC application that will run in my company's retail stores. Even though it is a web application, we own the store machines and have control over them. We have a "windows agent" running on the store machine which we can talk to via http post (it is a WCF service, and our web app has permission to talk to it from the browser). One of the web pages needs to be an "image viewer" page with some common things like Rotate & Zoom. Now, there are some WebForms controls that offer Rotate and Zoom. However, they take up server resources and generate a good bit of traffic between the server and the browser. For example, the Rotate function would cause an ajax call to the server, which would then generate a new image written to a .NET Canvas object, which would then be written to a file on the server, which would then be returned from the ajax call and refreshed inside the browser. Normally, that's a pretty good way of doing things. But in our case, we have code running on the store machine that we can communicate with. This leads me to consider the following approach: When the user asks to view an image, we tell our "windows agent" to download it from our image server to the store machine. We then redirect our browser to our image viewer page, which will pull the image from the local file we just wrote to the store machine. When the user clicks "Rotate", we cause JavaScript code in the browser to call our "windows agent" software, asking it to perform the "Rotate" function. The "windows agent" does the rotation using the same kind of imaging control that would formerly have been used on the server, but it does so now on the store machine. Javascript in the browser then refreshes the image on the page to show the newly rotated image. Zoom and similar features would be implemented the same way. This seems to be much more efficient, scalable, and responsive for the end-users. However, I've never heard of anything like it being done, mostly because it's rare to have this combination of a web app plus a "windows agent" on the client machine. What do you think? Feasible? Reasonable? Any pitfalls I overlooked or improvements / suggestions you can see? Has anyone done anything like this who would like to offer the wisdom of experience? Thanks!

  • HTML: how to create a "save as" button?

    - by user68759
    In your browser, when you want to save an HTML page that you are currently viewing, you normally go to the File menu and click Save As. Can I have a little button at the bottom of an HTML page that does the same thing? So instead of going to the File menu - Save As, I want my user to be able to click the button to save the page on to the disk. There is a solution exists using Javascript as far as I know, but it only works for IE. See here: link text

  • How to with extract url from tweet using Regular Expressions

    - by neutreno
    Ok so i'm executing the following line of code in javascript RegExp('(http:\/\/t.co\/)[a-zA-Z0-9\-\.]{8}').exec(tcont); where tcont is equal to some string like 'Test tweet to http://t.co/GXmaUyNL' (the content of a tweet obtained by jquery). However it is returning, in the case above for example, 'http://t.co/GXmaUyNL,http://t.co/'. This is frustracting because I want the url without the bit on the end - after and including the comma. Any ideas why this is appearing? Thanks
