After a bit of investigation, turns out that Safari on iOS6 will cache POSTs that have either no Cache-Control headers or even “Cache-Control: max-age=0”. The only way I’ve found of preventing this caching from happening at a global level rather than having to hack random querystrings onto the end of service calls is to set … Read more

To convert an object to a string, use JSON.stringify: var json_text = JSON.stringify(your_object, null, 2); To convert a JSON string to object, use JSON.parse: var your_object = JSON.parse(json_text); It was recently recommended by John Resig: …PLEASE start migrating your JSON-using applications over to Crockford’s json2.js. It is fully compatible with … Read more

I just tested this and verified that I can access the contents of an iframe with src=”http://google.com” embedded in a page served from “localhost” (tested under chromium 5 / ubuntu). For me the exact command was: Note : Kill all chrome instances before running command … Read more
eval() is not necessary. This will work fine: var date = new Date(parseInt(jsonDate.substr(6))); The substr() function takes out the /Date( part, and the parseInt() function gets the integer and ignores the )/ at the end. The resulting number is passed into the Date constructor. I have intentionally left out the radix (the 2nd argument to … Read more
With HTML5 you can make file uploads with Ajax and jQuery. Not only that, you can do file validations (name, size, and MIME type) or handle the progress event with the HTML5 progress tag (or a div). Recently I had to make a file uploader, but I didn’t want to use Flash nor Iframes or … Read more
