Ajax :: Upload File - Filename Passing In Js Function
Dec 20, 2009
I'm amending an upload script from Max's AJAX file uploader. [URL] I wish to display the filename after the file uploaded. The text in green are added by myself. However, I failed to display success status after the upload process successful. Do you know where I made the error?
This Scripts allows you to upload files using AJAX (I'm not an expert). The site claims it's the best way to upload files out there, and the file size is only 1 kb.
I couldn't get it to work for me. I downloaded the files to my computer, and opened the index file with my browser. It doesn't work (the demo on their site does); IE doesn't show any error messages or anything, and FF shows a single word that might be treated as an error notifier: 'undefined'. Does this thing even work? If it does, could anyone please give me detailed steps on how to using it on my site? Code:
I've created a PhP page(Main) which will list records and a link to change their "thumbnail". Clicking on it will open a "pop-up" which will present a "File input" box and when user select a file to upload, this popup-page will send the form fields to a "process page" using AJAX. This Process page will upload the file and on success returns nothing else the error to the Ajax object in Popup. On return, the popup page will just reload the thumbnail on main page if success and closes itself.
I'm sure I've described what I wanted to do. Again, in brief: Main->(Opens Popup)->Popup->(Send file using AJAX)->Process Process->(Upload File & return result to)->Popup->(Reload img on Main and closes itself)->Main Below are my codes:
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.
Last year, just a few days before holidays, I wrote a tutorial about a new feature available in Firefox 3 that allows web developers to do AJAX-style file uploads. Initially I intended to publish this tutorial as a SitePoint article, but it got rejected so I published it on my blog.
Now, I'd love some feedback. So, if there's anyone out there that has enough patience to read an exhaustive tutorial about uploading files with nothing more than JavaScript I'd like to hear her/his opinion. If it's crap just tell me 'cause indifference kills. Anyway, if patience is not your strong point there's a ZIP package containing both a "simple" and a "complex" take on the problem. Try those.
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.
<script type="text/vbscript"> Dim objWord Sub Btn1_onclick() call OpenDoc("K:DeloitteTeam1 Status reportJavaProgramshi.txt") End Sub
Sub OpenDoc(strLocation)
Set objWord = CreateObject("Word.Application") objWord.Visible = true objWord.Documents.Open strLocation End Sub </script>
I would like to pass the filename used above in the button code below so the above code could be coded only once and then mutiple button code could be used.
I'm actually new on jquery ajax. I just wanna ask a little idea about how to create simple file upload (with form) using ajax. I tried using this code: //form html <p id="status"></p> <form id="form1" enctype="multipart/formdata"> <input type="file" id="photo" name="photo" /> <input type="submit" id="save" name="save" value="Upload" /> </form>
I've a technical problem, i use jQuery Form Plugin and it's working well except for upload file. Effectively after uploading file we can't see any response in firebug. (You can see an example in the official website of jquery form plugin [URL] And in the response i call a script with
<script src="script.js" type="text/javascript"></script> My page get this file well but i have a javascript error on the "$" of $(document).ready(function() {...
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'm using AJAX for all the updates to the web site I'm building and it works very well. But now I face the need to:
1) Upload a file (an image or video) to a folder in the server.
2) Insert a row in MySQL with the name of the file plus some other information (year and a comment).
The user would upload the file and fill in the information in the same window, and should have a single message (if possible) saying that the file was added or not (meaning both the upload and the insert).I have been doing some googling and found information as how to simulate and AJAX upload, since it seems AJAX does not support file uploads (hope I'm wrong). This is what I found: [URL]
So following that example I could upload the file, and I'd have all the information from the form, in the PHP, and I could synchronize the upload and the insert, but then I can't figure out how to send the OK from the PHP to a Javascript (i guess) to update the html and display the message in the web site.
I'm trying to figure out a way to pass the filename before submission... I think I have to make an onChange command on the file field, but not sure how...
This is what I have done so far: <script type="text/javascript"> function theimage(){ var imgURL = document.getElementById('myfile').value; ste.execCommand("insertimage", imgURL); } </script>

And anyway, is this the right approach to do what I need?
Before I waste time trying to achieve this, could someone possibly tell me whether it is in fact possible to upload an image using the jquery ajax function?I have seen examples on google but they are not too clear how they achieve it.
i want to do (multiple) file upload(s) and display a progress bar. with firefox and safari it is no problem at all. only IE makes some problems.
my script is based on ajax-uploader, which can be found at www.srmiles.com/freestuff/ajax_file_uploader/ . you can do multiple file uploads. each upload will have it's own "form"-tag, so that each file is uploaded for its own. could be a good solution if there are "big" uploads.
so here is what i do:
i have a html-page in which several forms with file-input fields are generated. when i now hit the "one" submit button at the bottom of the page a javascript function upload() starts it will iterate through all forms (id='frmUpload_xx'), will get the filename, start a ajax request for the progress-bar function and do a form.submit().
if the first form/file is uploaded, a settimeout('upload()', 1000); is called and the next form will be processed. all form's have an target="uploaddiv", where uploaddiv is a invisible iframe. so the output of the upload script is put in this div. output should only be a "OK" at the end. no usefull output no info no nothing.
firefox and safari are working as expected, only IE stops after the first file is uploaded. i get an javascript error saying "zugriff verweigert/access denied" on object line x... this is the place where i call "form.submit()".
this is the upload-function:
function upload() { if (uploads.length>0) { form = document.getElementById('frmUpload_'+uploads[0]); if (form["filename"].value == ""){ alert("Please Choose a file to upload."); } else { filename = form["filename"].value; if (filename.lastIndexOf("")>0) { filename = filename.substring(filename.lastIndexOf("") +1,filename.length); } else if (filename.lastIndexOf("/")>0) { filename = filename.substring(filename.lastIndexOf("/") +1,filename.length); } makeRequest("upload_progress.php?sid="+sid +"&filename="+filename,progress); form.submit(); } } }
the strange thing is, that filename is filled correct, that means the object "form" is found and exisits. the first iteration is working, only the second ends with an error.
think it have something to do with redirecting the output of the upload-script in an iframe. after that IE can't access form - at least IE is not allowed to submit the form as i can access a form field (filename). i worked on that the last two days and haven't found a solution...
Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:
[URL]
The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.
Here is my Ajax script:
Code:
<script type="text/javascript"> function showResult(name,age,gender,ethnicity,facility) { if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")
[Code]....
Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.
Problem is, I can't access dataValues at the server side once I assign this same URL to the iframe.Is there any other way to POST JSON value through form submission without ajax? or any other way out, I am trying to download file that is based on some parameters and isn't a direct download link.

I am trying to create a javascript where, on clicking a button, I will be able to download the latest log file. But the log filename changes everyday as it takes the current date as part of the filename. eg. EMEA_20070806 i.e. EMEA_yyyymmdd Also, the previous day's log file is stored in the same directory.
How can I create a button where it will download the latest log file at all times?
