This is useful for pure JavaScript applications where you might want to parse file contents directly in the browser. Enabling this option will decode the base64 data into the raw file contents. When JavaScript reads the file data, it comes back as base64 encoded data. It is recommended to keep this option enabled unless you need to work with dropped images in JavaScript. When this option is enabled, this will be removed from the base64 string so that the pure base64 data can be processed or sent to a server. When JavaScript reads the file data, it comes back as base64 encoded data which begins with something like 'data:text/plain base64,'. after this is done we modify the default. This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options, HTTP. The PHPinfo page outputs a large amount of information about the current state of PHP. Of course, you can specify a different element with this option if needed. we start by creating a new asp.net mvc 3 web application and we add the file jquery-filedrop.js to the scripts folder of the project. PHPinfo page has been found in this directory. By default whatever you select with jQuery to will also have addClassTo applied to it. This is the element that will have the CSS class set with the overClass option applied to it. When files are dragged over the browser window, this is the CSS class that will be applied to the selected element or the element specified with the addClassTo option. This function can optionally be the only argument passed if you do not need to specify any other options. This option is required! You must provide a function to process the collection of file object that will be returned as the only argument. You may either pass in a function to loop over the collection of file (as in the example above) or you may pass in an option object if you need to be more specific. Let's show thumbs of images using FileDrop.File methods.įiles. This is a directory - it has no File API object. like sendTo() and readData() - see below. as file.nativeFile and file.nativeEntry. file is FileDrop.File with native objects accessible
files is standard FileDrop's FileList object. Īllow multiple selection in Browse dialog. Pure native JavaScript, no library is used. Lets you upload a file by clicking on the drop zone and, additionally, by dropping it from your computer for supported modern browsers. Safari 5 provides drag & drop upload but no file reading functions. Unless you are calling it directly FileDrop will transparently translate it to readAsArrayBuffer(). IE 6-10 don't support multiple selection in file open dialog.
IE 6-9 fire ondrop on but when the form is submitted this way sends an empty POST body so drag & drop is forcefully disabled for IE 6 (normal upload by clicking on the drop zone is still possible using iframe fallback). įirefox ~13 and later ignore overflow: hidden on
