Check How Many Days Have Elapsed Since A File Has Been Uploaded
Nov 21, 2010
I set up the following code to check how many days have elapsed since a file has been uploaded:
[Code]...
alert("Days since file was uploaded="+diff); My problem is that modified.getTime() doesn't work. Apparently the result of Oxml.getResponseHeader('Last-Modified') is a string, such as Sun, 21 Nov 2010 21:17:49 GMT. I tried and tried - but couldn't get to make a proper date out of this.
Is there a way by which I can validate in javascript whether the file I'm trying to upload is an existant one(i.e., one which is present in my local folder).
So I'm trying to create a custom file uploader which will display the name of the file selected, but since I can't seem to figure out how to do this I've settled for checking to see if a file has been selected, but I'm still having trouble with it.Here's what I have...
However the value doesn't change after the file has been selected. Could someone tell me a means of modifying this so that it will properly display once the file has been uploaded? Do I need to have some sort of constant refresh on the Javascript to check to see if the value has been changed?
I would like to create a script that behaves differently according to the date it was uploaded to the webserver. Meaning - if I send the script to my friends and each one uploads it to his server on a different date - each one will get a different behavior.
Something like:uploaddate=getuploaddate(); if uploaddate between Jan 1...Jan15, 2010 do this1; elseif uploaddate between Jan 16...Jan31, 2010
I am using uploadify (a jQuery plugin) to upload files as I am adding clients to my DB. I would like to attach files to clients. The issue #1 is that the client is a new client so it has not been added to the DB just yet. I have overcome this by getting the next Client_ID in the DB.
NOW the real issue is that all files that are uploaded should be prepended with this ID...something like: (29) ---i would like the parenthesis as an added open and close of the client_ID----I have searched on stackoverflow and uploadify.com but can't make heads or tails on how to do this.
I NEED TO DO IT VIA JS, because of the fact that I am using the PHP elsewhere in my application and I don't want to change it, if at all possible.
I would like to be able to delete an uploaded image file whenever a PHP page is navigated away from, either by the use of buttons on the page or the browser arrows.
I want to do this to stop a directory being filled with 'leftover' files.
I think that using an onblur function with the <body> tag would enable me to do this, the problem is that the filename is a PHP variable.
I have searched for an AJAX function that would enable me to do this, but haven't been able to find one.
I have a PHP script for uploading and cropping an image file, this file is selected by a form that calls the cropping script.
In the form there are buttons to Crop, Load File and Exit.
The Crop button starts the cropping process and finishes by deleting the original file.
I am a total newbie, but am trying to get my feet wet by adding some JavaScripts into/onto my website that I am creating. I am trying to have people "upload a file" which will then take them to my order page where it will tell them how many words their "file" has, then in the background divide the number of words by 350 for the page count then multiply by my price per page, then display their cost of their job? I seen one like that on another website [URL].. but cannot figure out how they did it. I'd like to be able to put this at the top of my order page where after they see the cost, they would fill in their own info (which I know how to do) and then submit the whole thing along with payment.
I have used this script for multiple upload using one file control. In this i have give limit for upto 3 times user can upload. also user can remove which is uploaded. But main problem is when user remove last uploaded file than its ok but when user remove first uploaded file and then add new file that time user can upload more than 3 files? Whats the problem I can`t found.
My script is
<script language="jscript" type="text/javascript"> function getCount() { var cnt = 0; for ( var i = 0; i < upload_number; i++ ) {
converting days to weeks and remaining days. For example : Total days : 152 = 147 Weeks and 5 Days: so I want to write a function getWeeks(152) and it will return an array of 3 elements 0 will be weeks and 1 will be days.
is there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
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:
How to display an elapsed time with javascript? for my page i will call an elapsedTime() function in the body tag onload. i want the elapsed time to display in a <span> tag. i just am not sure where to start.
I have the following code that will count the elapsed time and print the value in seconds after the user hits the stop button. However we are trying to get it to post the elapsed time in hours. So lets say the elapsed time is 20 mintues, the output would be .3 hours.
how can I check what is being return to rating.js from ajax.rate.item.php below?
rating.js
Code: if(window!=top)top.location=location.href; function RateItem(varItemId, varRating) { var varOrigClassName = document.getElementById(varItemId).className;
I am having troubles finding a way to use JavaScript to see if a file exists before an ASP file upload script runs. Is there an Exists check for JavaScript? I thought I found an ObjectName.Exists but doing this did not work.
I would need javascript code to check extension of uploaded file. File upload in not mandatory, but I need script to check extension and allow only JPG, BMP, PGN and other Image files.
I am trying to find a way to search to see if there is a specific file located in the current directory on the server. If a folder contains file1.txt or file2.txt and depending on which file is in that folder change a certain javascript variable. What it comes down to is, is there a way to search for specific files on the server and limit that to the current directory/folder.
When i select a file (through html file control) from local machine, before uploading i want to check if the selected file exist(because,after selecting and before submitting the form,user may change the name/delete the file from the source). so after selecting the file, i need to check the same file exist as it is using javascript/ajax. Back end is JSP.Eg: Am selecting abc.jpg from my system and changing the file name form the source as abcd.jpg, now abc.jpg does not exist. But i want to check if exist. If selected file does not exist, i want to display a message before uploading/submitting the form.
