So I have an web application deployed on tomcat. That application is a document browser[URL] that renders some html pages. In one of those pages I will have a svg that will change some colors if some files are/are not deployed in the server. So I am trying to create a javascript function that open that file. The code I am using is this:
Code:
<script type="text/javascript">
var xmlhttp=false;
/*@cc_on @*/
[Code]....
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.

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.

View 10 Replies View RelatedLet's say that I have generated var SomeVariable = true; from server.
On client side I have:
if (SomeVariable == true) {
do something
}
How could I first check if my variable is undefined? Or how can I say if
some exception occures please don't report error, just continiue?
If variable is not generated from server, it will report me an error..

View 12 Replies View RelatedI have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.
The script works fine when the requested XML file is stored on the same server as the script.
The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;
[Code]....
I am creating an XML document on my page with javascript. My question
is, is it possible to save that xml file on the server (I have write
permissions) only using javascript, ie no server code? This task would
be trivial using server code, but I was wondering if I can do it all
with client code and post backs? Well, any input?
Im writing client-side javascript and I want to do a server side include. There are many server files but only one will be included. These files contain peoples names and phone numbers. This info is packaged as a line of javascript but I can change that packaging if necessary.
The file name to include is being passed as a url parameter: [url]
I know how to parse the url string and stuff the ID number into a javascript variable.
I set <ICODE> foo = "/people/12345.html" </ICODE> and tried <ICODE><!--#include virtual="${foo}" --> </ICODE>
but this did not work.
Is there a way to do this with javascript given that the name of the file I wish to include is contained in a variable? If not, what is the usual way of getting the data in the server file into my client-side javascript?
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.
View 2 Replies View RelatedI 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:
<html>
<head>
<title>Restart</title>
<script>
var i = 1;
var msgarray = new Array();
msgarray[0] = ".";
msgarray[1] = "..";
msgarray[2] = "...";
msgarray[3] = "....";
msgarray[4] = ".....";
function setText() {
document.getElementById('msgtxt').innerHTML = msgarray[i];
i=i+1;
if(i==5) { i=0; }
testImage("../images/logo.jpg");
}
function testImage(URL) {
var tester=new Image();
tester.onload=load;
tester.onerror=setText;
tester.src=URL;
}
function load() {
top.centerFrame.canvas.location="../htmls/splash.htm";
}
window.setInterval('testImage("../images/logo.jpg")', 1000);
</script>
</head>
<body>
<table width="100%" height="95%" align="center" valign="middle">
<tr>
<td width="50%" height="100%" align="right" valign="middle">
<h3>Please Wait</h3>
</td>
<td width="50%" height="100%" align="left" valign="middle">
<h3 id="msgtxt">.</h3>
</td>
</tr>
</table>
</body>
</html>
Simple enough, checks to see if the image is accessible, I used it to check to see if my server had restarted yet, modify as you wish!
I am new to jQuery, and learning more about Js by doing. I can hand-code HTML and CSS very well and understand OOP effectively. However, troubleshooting complex Javascript code combined with jQuery is a challenge to me, but I really want to learn. I am using Windows XP Professional and IE 8, FF 3.6.

I have a website that uses javascript to communicate with the database for the CMS system.
I had a programmer develop a website who refuses to add a logical function to which I am going to have to do myself now.
When you delete an image or file on a page of a website, it does not delete it from the server. It just deletes it from the website and database only and I can see how this will eventually cause problems when files accumilate in the server.
Can someone give me some samples, direction or instructions how I would implement a function so that when the admin deletes the image on a website, it also deletes it from the server itself.
I want a certain JavaScript script to access an XML file on a different server.
I can use PHP or any other language needed if i have to. but the main file must be in JavaScript.
So, I have a dynamic PHP file on my server. I want to make it so browsers can take the code I provide and paste it in an .html, .php, or .asp file, and it'll display across the board.
The file would need to be included, unless someone thinks there's a better way of doing this?
The only example I could think of would be Google Adsense's code? But I'm not sure.
I am uploading text file on html page, that text file lies on desktop and getting updated at every hour. I will keep my html page on server so how will it upload that text file from my desktop ? it is being generated by one cloud sensor .
