  • Provide local fallback for CSS from CDN

    - by BadHorsie
    I'm loading the Bootstrap CSS on my page from the CDN bootstrapcdn.com <link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"> How can I test if the stylesheet was loaded, and if not provide a local fallback? I do not want to wait for jQuery or other libraries to load before doing the test; I want all CSS to be loaded on the page first.

  • javascript simple object creation test: opera leaks?

    - by joe
    Hi, I am trying to figure out certain memory leak conditions in javascript on a few browsers. Currently I'm only testing FF 3.6, Opera 10.10, and Safari 4.0.3. I've started with a fairly simple test, and can confirm no memory leaks in Firefox and Safari. But Opera just takes memory and never gives it back. What gives? Here's the test: <html> <head> <script type="text/javascript"> window.onload = init; //window.onunload = cleanup; var a=[]; function init() { var d = document.createElement('div'); d.innerHTML = "page loading..."; document.body.appendChild(d); for (var i=0; i<400000; i++) { a[i] = new Obj("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); } d.innerHTML = "PAGE LOADED"; } function cleanup() { for (var i=0; i<400000; i++) { a[i] = null; } } function Obj(msg) { this.msg=msg; } </script> </head> <body> </body> </html> I shouldn't need the cleanup() call on window.unload, but tried that also. No luck. As you can see this is simple JS, no circular DOM links, no closures. I monitor the memory usage using 'top' on Mac 10.4.11. Memory usage spikes up on page load, as expected. In FF and Safari reloading the page does not use any further memory, and all memory is returned when the window (tab) is closed. In Opera, memory spikes on load, and seems to also spike further on each reload (but not always...). But regardless of reload, memory never goes back down below the initial load spike. I had hoped this was a no-brainer test that all browsers would pass, so I could move on to more "interesting" conditions. Am I doing something wrong here? Or is this a known Opera issue? Thanks! -joe

  • custom php function creation and install

    - by Ben Olley
    I would like to know how to create a php function that can be installed in php just like the already built in functions like : rename copy The main point I would like to achieve is a simple php function that can be called from ANY php page on the whole host without needing to have a php function within the php page / needing an include. so simply I would like to create a function that will work like this : location(); That without a given input string will output the current location of the file via echo etc

  • Show a 404 instead of 500 in Rails

    - by Victor P
    In my rails app I have defined the routes so users can access records like http://mydomain.com/qwe2 But if they type a wrong "qwe2" they get a 500 page. I think a 404 would be more appropriate. How can I change the error page that is shown? Thanks

  • Web pages show empty band across the top

    - by Gerry
    In Chrome, site http://www.helpinghandspeople.com has a 16px empty band (background colour shows) across the top of the page. It's not supposed to be there, but I can't figure out how to make it go away. In Firefox, the home page shows fine, but login and a few other pages show a 24px band. Viewing source and running inspect element are not helpful. Does anyone have a suggestion where to look? Thanks Gerry
