Getting Size Of Image In Pixels Before Upload?

Nov 8, 2011

If I have an image upload box on my page and I wanted to check the image either after selected or before the form is submitted to import it, is there a line or command I can use to return the size in pixels(width*height)...

I've seen it done and I'm assuming jscript has something to offer here but my googling has come up a bit short so I'm not too sure where to begin..

Match Width In Pixels To Textbox Size?

Jan 17, 2010

I have a div that appears directly below a text box. When the user clicks on an item in the div, i place it in the textbox. I want the width of both the textbox and the div to be that of the largest item in the div.

However, setting the textbox to have the same width of the div will not show all the characters of the selected text. I assume this is because of differences between pixel width and the input size property.

Restrict File Size Before Upload?

Jun 14, 2011

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?

Plot And Attach Pixels To A Scrolling Image

Jun 25, 2009

I have an img of a map of Europe in a div. I want to plot routes between cities in Europe as dotted lines. The image is scrollable and I want the routes to scroll with the image. So the routes should be attached to the image. Furthermore, when drawing routes outside of the viewable area, the routes should be clipped so they don't show up outside of the image. but when the image is scrolled, the routes should appear.

Here's a link to the dev site: [url]

Here is my code:

Finding Upload File Size - Javascript

Sep 8, 2006

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.

JQuery :: Get File Path & Size Of The File To Upload In Internet Explorer 7?

Sep 1, 2011

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.

Upload Huge File Size: "The Page Cannot Be Displayed" Browser Error

Jul 23, 2005

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.

//UploadForm.jsp
<FORM NAME="InputForm" ACTION="UploadAction.jsp" METHOD="POST"
enctype=multipart/form-data>
<input type="file" name="fileName">
//etc ...
</FORM>

After I deploy the application to the web server, if I upload a small
file size, it is fine.

But if I upload a huge file size more than 10MB, then it cannot even go
to UploadAction.jsp.

After 30 seconds, it has error "The page cannot be displayed" shown on
the web browser.

It cannot even go to UploadAction.jsp. But both UploadForm.jsp and
UnploadAction.jsp are in the same machine.

Interestingly, if I test in local machine, I can upload any file size
without problem. I don't have any hints now. any ideas?

JQuery :: Size Of An Image In A Div (image Bigger Than The Div)?

May 26, 2010

I'm having a little trouble with something a bit ridiculous. I have an image in a div, let says that the image's width is 100px (but in fact 300px, resize with em) and the div's width is 75px (it's an absolute div created by a plugin). I tried to do $('img').width() naturally, but it gave me the div's width. I tried some natives javascript methods (clientWidth, offsetWidth and scrollWidth), same things (but Firebug is saying that clientWidth is 100px, not 75px :'( ).

Ajax :: Refresh Image After Upload?

Jul 9, 2010

I have a script which allow users to chnage there profile image, and it allmost works perfect. The script is set up so when a user uploads a new picture it overrides the previous one, so if a user have an ID, lets say 15, the image would be called 15.jpg. The problem is that when an new upload is finished it still shows the old image, I think by cache, and thats no good. How do I refresh the image with ajax so when the script has done uploading the image is the new one?

The javascript upload.js:

Code JavaScript:
<!--
function startUpload&#40;&#41;&#123;
document.getElementById&#40;'f1_userimage'&#41;.style.visibility = 'hidden';
document.getElementById&#40;'f1_upload_process'&#41;.style.visibility = 'visible';

[Code]....
