After I click the browse button and select a file, sometimes there is a delay when the selected file appears. Why does this happen? Thank you.

Im making upload image from mobile to website. When user click on upload button i will disable "save" button until image is uploaded. But when user cancel upload after click on upload button, i dont know how to detect that event to enable "save" button. I found this solution How to detect when cancel is clicked on file input?
But It's only work on desktop. On mobile, cancel action is total different.
Another way you can do that, instead of disabling the save button, is to hide the save button when user clicks on upload. When user clicks on cancel button, you can display save button again.
i have my Main.js file in content_scripts. Main.js file provides a button and when the user click the html page is saved with reloading the html page.But when user clicks button for a second time the button is not working as some of the previous values where set when the button were clicked first time.Is there any way in chrome than Main.js will be automatically reload or execute as fresh script on every click.Windows.onload methos is not working on my Main.js file so how i solve this
It's not possible you can use location.reload function
What I want to do is: when a user clicks on a button, a folder browser should pop up almost the same way when <input type="file"> is used. The only difference is that I don't want that "Open" button, I want a button with "Save" as text. See that I'm not looking for a file saver in javascript, I just want a dialog that user can navigate inside folders, insert a file name and click on a button called "Save", so that I can make the file saving server-side.
Thanks in advance.
The file browser is part of the operating system, not the web page. Sorry.
I'm building a page where a user can upload multiple files through uploadify. I'm trying to do it so when the user has selected which files to upload, he can click a button to hide the upload queue and go about doing other things, and later he can click a button to bring up the uploads panel again and see the progress.
However it seems that if the upload button is hidden, then uploadify cancels any ongoing uploads.
What can be done about this?
You can change the height of the container div to 0 rather than hiding it. It works.
I'm developing a custom module for Drupal dealing with Document Management. At this point, the module loads, you can upload files (via a hidden iframe and some ajax requests), browse directories and set various levels of permissions. And everything works perfectly in Firefox.
Issue:
In IE however, I run into an issue. For some reason when I upload a file the save file dialogue pops up and asks me to download the file I just uploaded. It looks like it's asking me to download it from the web-servers tmp location however, as that seems to be the file-name and such. However, if I hit cancel and refresh the page I can see that the file I uploaded did actually get uploaded to the server.
Here is how the upload process works. Click the upload button. The upload button is the standard file input form element hidden and placed over a styled version of the button. Clicking on this causes the "Choose a file" dialogue to open.
Select a file and click "Open". A modal dialogue pops up asking you for some further information about the file. The modal is part of the same form element but remains invisible until you click Upload button
Clicking save in the modal causes the file to be uploaded. The "action" attribute on the form is pointed to a page and the target is the iframe.
The iFrame is polled a few times every second to see if it's contents have changed. When the file is uploaded a "success" message appears in the iframe. Since it belongs to the same domain, I scrape the content within the iframe.
Once the iFrame says that the file has been uploaded, I use some JS to update the application with the name of the file
Since I can't use Firebug in IE, I have to stick to utilizing Microsofts Web Developer Toolbar, which makes it very hard to figure out if the bolded step is actually occuring. It seems like it should, since the file IS being uploaded. It is just getting interrupted by that file download dialogue.
Since no one seems to have an answer, I'll post the fix I found. I doubt it's perfect, but it's the best solution I could come up with.
It turned out to be an issue with the polling as suspected. The fix ended up being instead of outputting json to the iFrame, just output some JavaScript that calls a function that updates the main window. That simple.
