    javascript - What to use instead of FileReader for Safari? - Stack Overflow

    programmeradmin1浏览0评论

    (Am new to web programming, so apologies for any lack of rudimentary knowledge.)

    My page allows a user to select a file that is then read clientside & displayed in a textbox on the page. The easiest way I found to do this was to use a FileReader object, which works fine in Firefox and Chrome.

    This doesn't work in Safari (yet), so what should I do instead?

    //When the eventlistener detects a change in the input file...
var file = evt.target.files[0]
var reader = new FileReader();
reader.onload = function (e){document.getElementById('data').value = e.target.result};
reader.readAsText(file);

    Relevant Notes:

    • I'm working with Safari for windows
    • Right now the page is local as is the file to read. Chrome had issues with this until I used the flag --allow-file-access-from-files

    Sadly, the only answer I can e up with will hog some extra bandwidth.

    Firstly, use something like if (typeof FileReader !== "undefined" or Modernizr to follow your normal flow for the browsers that DO support FileReader. Otherwise, POST the file via AJAX to some server-side script that echoes back the contents.

    So for pliant browsers, you get to save yourself some bandwidth and for non-pliant browsers you have to take one for the team.

    Another solution is to use "A FileReader polyfill for Internet Explore and Safari using Flash"

    See: https://github./Jahdrien/FileReader
