Jquery: change event to input file on IE

I have a form to upload files, and it should fire the submit after the file selection.

On FireFox/Chrome it goes well, and submits the form after file selection, but I can't do this on Internet Explorer.

Already tried with click/propertychange but nothing happens. Some code I already tried:

$("#attach").attr("onChange", "alert('I chan开发者_开发知识库ged')");
$("#attach").live($.browser.msie? 'propertychange': 'change', function(e) { ... });

This input file is created on the fly; because of it I use .live() to bind the event.

Any suggestions?


I know this is several months late, but I just ran into the exact same behavior in IE7; in all other browsers, the change event for file inputs happens after file selection. In IE7, it happens only if you trigger the file select again, or on blur.

Here's how I ended up fixing it:

var $input = $('#your-file-input-element');

var someFunction = function()
{
    // what you actually want to do
};

if ($.browser.msie)
{
    // IE suspends timeouts until after the file dialog closes
    $input.click(function(event)
    {
        setTimeout(function()
        {
            if($input.val().length > 0) {
              someFunction();
            }
        }, 0);
    });
}
else
{
    // All other browsers behave
    $input.change(someFunction);
}

Technically you could/should filter the hack condition to just IE7, since IE8 behaves properly on the change event, but it also has the same behavior as IE7 on suspending timeouts while browser-related chrome is visible (I guess it considers it blocking I/O), so it works as-is.


This is really late, but I was having the same problem, and I solved it by using a styled <label> tag with a slight workaround for Firefox.

http://jsfiddle.net/djibouti33/uP7A9/

The Goals:

  1. allow user to upload a file by using standard html file input control
  2. hide standard html file input control and apply own styling
  3. after user selects file to upload, automatically submit the form

The Browsers:

  • Firefox, Chrome, IE8/9, Safari
  • IE7 didn't work, but it might if you add that browser to the workaround detailed at the bottom

The Initial Solution:

  1. Hide the file input by positioning it offscreen. Important not to display:none as some browsers won't like this.
  2. Add another styled element to the page (link, button).
  3. Listen for a click on that element, then programmatically send a click to the file input to trigger the native 'file explorer'
  4. Listen for the file input's onchange event (occurs after a user chooses their file)
  5. Submit the form

The Problem:

  1. IE: if you programmatically send a click to a file input in order to activate it (2), programmatically submitting the form (5) will throw a security error

The Workaround Solution:

  1. Same as above
  2. Take advantage of the accessibility features built in to the tag (clicking on a label will activate it's associated control) by styling a tag instead of a link/button
  3. Listen for the file input's onchange event
  4. Submit the form
  5. For some reason Mozilla browsers won't activate a file input by clicking on it's .
  6. For Mozilla, listen for the click on the label and send a click event to the file input to activate it.

Hope this helps! Check out the jsfiddle for details on the html/js/css used to make it all work.


Format it like this:

$("#attach").change(function() { 
  alert('I Changed');
});

Update: After answering another question on this earlier, we realized this was fixed as part of the jQuery 1.4.2 event re-write, just update to the latest version to resolve the change event issue with <input type="file" /> in IE.


I used the following solution. I tried to make it as self-contained as possible.

(function($) {
    if ($.browser.msie == false)
        return;

    $('input[type=file]').live('click', function(e) {
        var self = this;
        var blur = function() {
            $(self).blur();
        }
        setTimeout(blur, 0);
    });

})(jQuery);


This has always worked for me in IE6 ad IE7.

$('#id-of-input-type-file').change(function(){});


In IE onchange event works fine when it filled out in html tag directly. Like:

<input type="file" onchange="uploader.upload()" />


This is likely a problem with a race condition with input fields in IE. By using setTimeout the function that is executed will then register that a change happened. When the UI code is performed in the onChangeEvent, that event hasn't fired yet as it appears to IE.

I solved a similar situation by doing the following inside my change handler:

if (jQuery.browser.msie) { setTimeout(DoSomeUIChange, 0); } else { DoSomeUIChange(); }

The DoSomeUIChange is executed after the current code on the event queue and so removes the race condition.


I was having the same issue with IE (including IE 9). The UI logic is:

  1. click on a div element triggers the click event on a file-input-element so that user click on a div trigger file open dialog
  2. bind the change event handler to the file-input-element to ensure the form is submitted when file open dialog closed

The app (running inside an iframe) works like a charm on Chrome and FF. But soon I found it doesn't work on IE as when user selected a file and close the dialog the form didn't submit.

The final solution is to drop the logic #1 "click on div element trigger click event on file input element" and let user to click on the file input element directly, and then it works.

BTW, the reason we have a div element is we want to hide the browser rendered controls because we have everything in the background image. However set display to none makes the control not able to respond a user interaction event. So we move the file-input-element to outside of the view port and use a div element to replace it. Since this doesn't work on IE, we end up with move back the file-input-element and set it's opacity to 0. On IE 8 or less which doesn't support opacity, we use filter to make it transparent:

#browse {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    filter: alpha(opacity=0);
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
}


I found this solution In HTML hide file element (don't use display: none, won't work in IE), prepare onchange event of IE:

<div style="width: 0px; height: 0px; overflow: hidden;">
  <input id="ifile_template" type="file" onchange="this.focus(); this.blur();"/>
</div>

In javascript for IE bind function to blur, and for FF,CH bind function change():

$(iFile).blur(
  function () {
    ...some code...
  }
);

// FF, CH
$(iFile).change(
  function () {
  ...some code...
  }
);


For IE You can use the "onfocus" event to catch the change of uploading file. Once the file browsing dialog is closed the onfocus event is triggered. You can check this by adding this line to your page:

<input type="file" onfocus="javascript:alert('test');" />

Once the dialog is closed the alert message is shown.

This solution is only for IE, not for FF or Chrome.


My solution:

setInterval(function()
{
    if ($.browser.msie) $("input[type=file]").blur();
},500);

Not pretty, but it works. ;D


I can confirm, at least that it only works after a blur event takes place, similar to a radio and checkbox in IE. I am probably going to have to add some kind of visual element for the user to click and tell me when they have picked their file.

lame.


$("#attach").attr("onChange", "alert('I changed')");

It works in IE, but if you want to emulate "live" behavior, you should add "onChange" attribute to each new element when create its.


jQuery doesn't seem to recognise the propertychange event. I added it to the DOM node using IE's attachEvent().

var userChoseFile = function($input) {
    // ...
}

var $input = $(/* your file input */);
$input[0].attachEvent('onpropertychange', function() { 
    userChoseFile($input);
});


Look at these fiddle http://jsfiddle.net/uP7A9/531/

HTML:

<input type="file" name="PicturePath" id="fileUpload" accept=".png,.jpg,.jpeg,.gif,.tif" />

jQuery:

$("input[type=file]#fileUpload").on("change", function () {
    alert('hi')
});

it works for all browsers, tested.
