I want to put some additional checks while loading the file for that I need to check where each line contain the "|" symbol or not which I am using as a file delimeter.Can anyone tell how can we read the file line by line in javascript.
View 3 RepliesI am looking for a way to select a file from a list and load it into a webpage. The page and the files are stored on a sd-card for off-line usage, I know that listing files remote dynamicly needs a scripting engine but since the sd-card is on the client side that is not possible, but I can make a list of those files when creating them.
It is intended for a datalogger on a tractor-puller, I create csv files with a bash script on the logger and for off-line viewing I use a javascript charting engine which loads the csv file, the files have the creation date as filename and I can make (and maintain) a list of files when creating them. The plan is that the we can select another data set (run) from within the browser and show that one. I have setup an example at [URL]
I use the following to load an xml file...
xmlDoc=document.implementation.createDocument("","",null);
xmlDoc.load("file.xml");
xmlDoc.onload=getmessage;
How do I check if it had loaded correctly? I read something about a ready state you can call?
What's the simplest way to fetch a js file from the current website, then
cache it?
I'm using dojo, which has a large js file when using the built version.
As a mercy for dialup users, I want to serve up a tiny 'loader' html page
(containing an animated 'loading...' gif) which, when loaded:
1. retrieves the big js file, and plants it in the cache
2. when the js file is retrieved, then sets document.location to
the url of the real website page which uses this js file, and
thus redirects to that page.

What I mean by this is how do you load an xml document that has been inputted as a string in a form. I would've assumed it was something like this, but this doesn't seem to be working.

i was wondering if it is possible to load text into a string from an
external text file. the reason is that i have a very large string and
it is making my script very messy.
also, is it possible to have some dynamic parts of the text from the
text file? for example, if i load in a string and there is a part of
it that inserts a value from a variable like the following:
'The number of people is ' + var_people_num;
....so the text from the external file would load but these parts would
be given the value of a variable contained in the script that calls
the external file. its not absolutely crucial that i obtain this but
it would help me seperate large chunks that complicate the script.
As we all know, JavaScript is client side and php is server side, (the php
code is 'allowed' to do stuff on the server that JavaScript cannot).
The problem with php is that it timeout after a while, (and the user also
has no clue as to what is going on for a long time).
I need to run a script on the server that could take a very long time.
So what I was thinking is mixing both JavaScript and PHP
Something like,
<script>
var endvalue = 1000; /* some number that the server can calculate
quickly */
var i = 0
while (i<=endvalue)
{
/**
call a php file that will do some work
somefunction.php?someNumber=i
*/
}
</script>
That way the server does the work, while the client keeps it going.
Ideally I would also get a return value/string from the php script.
I have a JS file on site A which needs a few parameters from a short text file on site B. Since crossing domain boundaries in JS is problematic, the way I do it is that the JS actually opens an intermediate PHP file on site A which redirects to the destination page in site B. Here's how it goes:

The problem is that this takes a long time. I would really like to speed this up. For example - I thought of using a direct IP address, so that there won't be any need a DNS server (using
Code...
) but this would expose me to hackers as it would make my Hostgator username visible. According to HG support the above format is the only way to access my subsite via direct IP.
Any ideas on how to speed this up, either by bypassing DNS (but without exposing username) or by offering another way of reading data across sites?
I'm building a home page with an update checker. A function, called 500 millisecs after the page loads, appends an external .js file and compares a variable on it to a different internal variable. If the internal variable is lower than the external variable, then the update prompt is displayed.
This all works fine, but the status bar says "Read www.primedesigning.com" (the site with the external js), or sometimes "Transferring from www.primedesigning.com". But, if I hover over any link, the status bar goes back to "Done". Also, if I leave my mouse still, wait for the update prompt to appear, and then move the mouse, the status bar says "Done".
I have the Fasterfox extension installed, and it confirms what the status bar is saying. It never stops loading unless I do 1 of the 2 solutions mentioned above.code...

I have some code that performs differently in Opera than it does in any other browser. So I have a stylesheet specifically for opera. Is there a way to do something like this, where I check the browser, and if it's not opera, then load the default sheet, otherwise load the opera-specific css?

i don't think it's because i'm using an image map (i know... ol' skoolin it)
I'm currently working on a site and need to have a small section that displays 5 or 6 headlines. The same headlines will displayed on various pages and will occassionally be updated.
The site pages are static .html in design and i'd prefer to keep it that way rather than start introducing php for such a minor part of the site.
I am wondering if there is a javascript solution to this, whereby the headlines could be loaded via a .txt / .xml document or something similar?? That way i could just manually update the file and reload it to the server and the headlines would be updated.
I guess i'm think something similar to cushyCMS but that i can implement directly.

A program I am writing will be loading the data of a file into an array. This data is read as an image and is displayed. Part of it will be the modification of palettes, so if I click Palette 4, it would go in and edit the array to have new contents (predefined by me) and redisplay the image in place of the one that was there before. How would I load a file into an array and display it as an image and stuff?

I'm fairly new to jquery so apologies if this is a very simple question with a very simple answer, but I just can't figure out the solution. I have an overlay div, and when I close the overlay I want to remove the html inside it and then re-load it from the specified file. I have already worked out how to empty the div, but what I now want to do is re-populate it with the content from a separate file on my web server.

how to load an XML file into a DOM. I can get it done in IE, but in mozilla I am missing something. Here is what my loadXML() function looks like:
function loadXML(){
try {
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.onreadystatechange = verify;
hasFile = xmlDoc.load(info.XMLDocument);
if (hasFile){
xmlObj = xmlDoc.documentElement;
allTopics = xmlObj.getElementsByTagName("topic");
}}
catch(e) {
xmlDoc = (new DOMParser()).parseFromString(document.getElementById('info').innerHTML, 'text/xml');
hasFile = true;
allTopics = xmlDoc.getElementsByTagName("topic");
if (hasFile){
allTopics = xmlDoc.getElementsByTagName("topic");
alert(allTopics[0].firstChild.getAttribute("name"));
}}}
Where verify is another function. The try part works for IE, but the catch part doesn't work for Mozilla. I am not finding any information as to really use an XML DOM properly in Mozilla. I'm trying to get allTopics to be a handle on the same thing in both the "try" and the "catch".

the link above shows a google map with randomised markers. It's a great effect, the only thing being that the locations are randomised.
I want to load an xml file of exact locations so that they can be panned to when the text is clicked on the right hand side.
I have tried loading an xml file to achieve this without success.
