I'm trying to put in place a file upload validation check. So at the client-side, the User selects a file. Before uploading, at the GUI, if the file exceeds an imposed limit, it will prompt the User that it exceeds the permitted size for upload.
And if it is within the permitted size, the full file path of the file to be uploaded will then be obtained and then used for the actual upload to the Server.
My program is built on EXTJS and Java, running using Tomcat. Browser restricted to Internet Explorer 7 only.
I have a problem with the latest version of the jQuery Form Plugin (2.80). To be more precise, I guess I am doing something wrong, and with an older version (2.67) somehow it didn't matter.With the old version, the file was uploaded without problems. Now Firefox opens a new Tab on clicking the submit button and nothing is done. Chrome doesn't open a new tab, but also nothing happens. In Wireshark I can see that there is no file attached in the POST message with the older version, the file was sent.My first guess was that my file handling on the server side is erroneous - but on the other hand, when there is no file attached, what should I handle there?
In JSP / HTML, I want to restrict the size of file being uploaded.
<input type="file" name="myfile"/>
If the user trying to upload a file size bigger than some value say 5MB, i want to give mesage to the user. I don't want to wait till the file gets uploaded to server and then validate the file size. I am looking for client side validation. Can it be done using scripting language or any other way?
Need a solution for this in Internet Explorer. I got a solution using ActiveX control:
var myFSO = new ActiveXObject("Scripting.FileSystemObject"); var filepath = document.getElementById('myfile').value; var thefile = myFSO.getFile(filepath); var sizeInBytes = thefile.size;
But ActiveX controls are not allowed in our application. Is there any alternative way for this?
I have used ASP.net 1.1. In that application user can upload the file(any printable document like doc/xls/ppt/pps/jpg/gif etc.,). The user allows to upload a max of 4MB.
But if the user uploads more than 4MB I'll issue a msg. But in slow network, the user needs to wait for much time to upload and even get error msg.
I want to stop from client side itself. Once the user selects the file to upload it shud b checked frm Javascript.
* Is there any way to do achieve this? * The user should not change security settings in browser, if u suggests some method. * If it is not possible/meaningful then please tell me the reasons very clearly. So I can stop searching. * Please note any printable document can be uploaded.
I am trying to implement this jQuery form plugin to do ajax file uploads. Although the documentation is great I am still a little unclear about one thing. Usually when I do ajax submissions I return a response in JSON(using PHP), something like :
When doing some simple tests I have run into a problem and I believe it is due to the way this plugin handles JSON responses. My form :
[Code]...
This does not result in the success event firing but rather the error event. In the plugin documentation it states that it does not handle json responses well and that it recommends wrapping the response in a textarea. Unfortunatly I'm not sure what they mean by that, and what I've tried so far has not worked. ould anyone give me some advice as to how to output the response in JSON properly? Could anyone that has used this plugin for AJAX file uploads offer any advice on doing so?
I've added file upload support to the form plugin and I could use some help testing it out.If this feature interests you then go ahead and grab the beta plugin at:URL...File upload support is baked right into the plugin and there are no external dependencies.The plugin will automatically detect file input elements and use an iframe to submit the form if there are files to be uploaded.No extra coding or metadata is needed to take advantage of this new feature.In addition, even though an iframe is used instead of the XHR object, callbacks and global triggers still work as expected (so any code that you have in place to display activity indicators or blocking elements will still work).However, there are some challenges when using iframes in this manner.For one, it is quite difficult to determine if the submit operation succeeded or failed.The iframe becomes the target of the submit operation and so that is where the server response is written.The form plugin does its best to determine the data type (html, xml, etc),but the status is always 'success' unless an exception is caught during the type determination.URL...
If you use this page for testing *please* be kind to my server and only upload small files! I'd really prefer that you download the plugin and integrate it into your own test environment if possible.I've done some testing on FF, IE and Opera and the results are encouraging. I don't have access to Safari so I'm sure there are issues lurking for that platform.If you're interested in the code you can find it all tucked into the end of the ajaxSubmit method in a function called "fileUpload".
This is driving me nuts. I'm using the File Upload. It works fine in Chrome, but in FF4 and IE9 it executes the beforeSubmit, but never reaches the success, and the file never reaches the server.
I'm novice with jQuery and Web in General and I have a problem with "jQuery Form Plugin" [URL]... Everything works well except when trying to upload large files (I need to upload video files).Itriedupload a video with about 24 MB in the example(demo) page in the[URL]../#file-upload and seems that i don't get the expected result. Can you tell me what constraints or custom options i'm facing with this plugin or IIS7 for that matter? Is there a way to see that something went wrong? Because the file seems to be uploaded but nothing happens after.
I have an upload file operation in the web application. UploadForm.jsp is the form, and UploadAction.jsp is the form processing. The web server is Websphere.
I implemented Malsups jquery form and use it for ajax file uploads. Works fine in FF, but in IE as soon as the ajax has completed the upload IE gives me a File Download box - Security warning. If I click on save it save thereturnedJson object (I do JS call onsuccessto get a file list and display it). If I click cancel or save on the popup has same effect the file still gets uploaded but just looks ugly.
How can I get rid of this? All coming form the same domain, calling from the same domain. This is on a python django project and I am testing it on the dev server.
Its pretty basic jquery nothing to exciting, don't get why IE would cause.
I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:
1. Malicious user trying to collapse the website sending big files.
2. Users that have not seen the warning “Maximum size: 100 KB� for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.� And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!
I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:
“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
Is there a way to determine which css file is applied to a page using js?I have a regular css file and a "print" css file linked in the html <head> and I want the js to determine which css file is being used to style the page and basically turn itself off if the print version of the css is being used.
I know that the input "file" type can't be customized very well using css, so I figured I might try to make my own with javascript. The only problem is, I don't know too much about javascript. point me in the right direction on how to make my own custom file upload box in javascript that works the same way as the default one works (so I don't have to edit my PHP coding). Also, heres something I'd like to achieve: [URL]

I need some way to use ajax to upload a file mainly a image and a video to my website.
I googled around and found many people saying it's impossible to do it with ajax.. but there are jquery work around plugins where it uses an hidden ifframe to submit your files.
I am trying to upload a file and text using jquery ajax. The upload would include validation that is done with php and echoed on a div on the uploading page.
