Play mp3 file after uploading it with html5 drag and drop upload

由 回眸只為那壹抹淺笑 提交于 2019-11-27 11:00:51
问题 Is it possible to first upload an mp3 file with the html5 drag and drop upload system, and then play it with webkit's audio API (http://chromium.googlecode.com/svn/trunk/samples/audio/index.html) without submitting a form (in Google Chrome)? Is it possible to do in FF with Mozilla's audio API? If so, how? Also, are there any tutorials in existance for webkit's API? I have not been able to find any. 回答1: The basic process you need to follow is Capture the files using Drag and Drop Files

Intercept and modify DOM before page is displayed to user

由 流过昼夜 提交于 2019-11-27 09:30:20
I'm trying to create a Firefox addon (using addon SDK) that will modify how the page is displayed, mostly as a training/learning exercise. For some tasks (like augmenting pages with new functionality) using pageMod is perfectly fine. Page loads and I run some JS to show/hide/add elements. My problem is: can I perform modification on DOM (so: the HTML document that is returned by server) before the page even starts displaying? For example: the page returned from server is: <html> <body> <table> <tr> <td>Item 1.1</td> <td>Item 1.2</td> <td>Item 1.3</td> </tr> <tr> <td>Item 2.1</td> <td>Item 2.2<

问题 In reference to my first post: Mozilla use a C DLL with js-ctypes I'm trying to build a DLL to be used from a Mozilla Firefox extension. I created a little C code and compiled it with GCC.

What is the concept of Array.map?

I am having problems understanding the concept of Array.map . I did go to Mozilla and Tutorials Point, but they provided very limited info regarding this. This is how I am using Array.map . It is a little complex (a bit of d3.js involved; just ignore it) var mapCell = function (row) { return columns.map(function(column) { return { column : column, value : getColumnCell(row, column) } }) } //getColumnCell is a function defined in my code //columns is array defined at the top of my code I do not understand exactly what this code is doing. I know its returning a new array and stuff but this part
