Handle file download from ajax post
I have a javascript app that sends ajax POST requests to a certain URL. Response might be a JSON string or it might be a file (as an attachment). I can easily detect Content-Type and Content-Disposition in my ajax call, but once I detect that the response contains a file, how do I offer the client to download it? I've read a number of similar threads here but none of them provide the answer I'm lo
JavaScript post request like a form submit
I'm trying to direct a browser to a different page. If I wanted a GET request, I might say document.location.href = 'http://example.com/q=a'; But the resource I'm trying to access won't respond properly unless I use a POST request. If this were not dynamically generated, I might use the HTML <form action="http://example.com/" method="POST"> <input type="hidden" name="q" value="a"> </form> Then I w

Strange behavior in do/while statement on Galaxy S5 and Android 5.1.1
I face strange behavior of do/while statement on Galaxy S5 and Android 5.1.1. If you have any information, let me know. int i = 0; int j = 0; do { Log.d(TAG, "[test do-while 1] i = " + i + ", j = " + j); i = 0; Log.d(TAG, "[test do-while 2] i = " + i + ", j = " + j); i++; Log.d(TAG, "[test do-while 3] i = " + i + ", j = " + j); i++; Log.d(TAG, "[test do-while 4] i = " + i + ", j = " + j); j++; Log
Bubble Highmap using Lat Long
I am working on drawing a bubble map using highcharts and i have reached to a certain point where I am successfully plotting the bubble based on the state code (in/RJ) and value (1000). http://jsfiddle.net/voidSO/h2f4ugz4/ $(function () { var mapData = Highcharts.geojson(Highcharts.maps['countries/in/in-all']); var data = [{ "z": 10038, "code": "RJ" }, { "z": 100, "code": "PB" }]; $('#container').
Is there a JavaScript / jQuery DOM change listener?
For a long time, DOM3 mutation events were the best available solution, but they have been deprecated for performance reasons. DOM4 Mutation Observers are the replacement for deprecated DOM3 mutation events. They are currently implemented in modern browsers as MutationObserver (or as the vendor-prefixed WebKitMutationObserver in old versions of Chrome): MutationObserver = window.MutationObserver |
What happens to JavaScript execution (settimeout, etc.) when iPhone/Android goes to sleep?
I have a jQuery Mobile web app which targets iOS and Android devices. A component of the application is a background task, which periodically checks for a.) changes to local data and b.) connectivity to the server. If both are true, the task pushes the changes. I'm using a simple setTimeout()-based function to execute this task. Each failure or success condition calls setTimeout() on the backgroun
