I would like to read a csv file that is on the server into a Javascript array but not sure how to do this. It needs to work on more than just IE.

View 10 Replies View RelatedI am very new to javascript and programming and I need a little direction. I have working a javascript that reads the value of radio buttons and writes them to a text file. My code is at [URL]. The text file has the following format:
Name|Email|Location|Comment|5|5|5|3|2|1|4|5|3|2|0
Name2|Email2|Location2|Comment2|1|3|0|3|2|0|2|5|1|2|3
What I need to do is have javascript read the text file (c: estfile.txt) and put each section of information (name, comments, numbers, etc.) into an array. Then, add the number from each columns up. For example, the first number from Name and the first number from Name1 is 5 +1 = 6. This sum is then added to another array that can be printed on the screen. I know this is a lot of information.
I am working on a project involving the Google Maps api. I have an application that spits out a text file with lat/lng coordinates plus some other info. I'm trying to figure out how to get the data from the local text file into a javascript array that can then be used by the Google Map api to create the map.
Any suggestions on how to go about doing this? I'm fairly certain that there is not a way to do it just with Javascript, but I thought I would ask. If not, any suggestions on how to do it, perhaps with xmlhttprequest and a PHP script? I don't need the text file to actually be saved on the web server, but if that's the only option then I can go that route.
This is a "can I" or "is it possible" question:
If I have one main html file that calls an external JS file that contains only an array (infoArray), know I can do this code...
Now the question...
Instead of 2 different main.html files, to load the different inforArray.js files, can I somehow overwrite the contents of the infoArray
AFTER the information has been loaded from the first external JS file?
I have seen code that adds elements to the <head> section as the page loads,
is there something similar to load/change array information during or after page load?
Or is this something that should be done by having text information in the file and loading with ajax and processing to an array afterward?
I need to make a javascript that when I am at a page within a game I play and click the javascript, it will get the value of a table cell, separate them to x and y variables and then put the values into a link that opens. The open link is of a php script that uses $_GET for the values of the variables to query my database.I am terrible at javascript and have been trying to do this for 2 days now with no success.Here's the scripts so it is easier to understand:This is part of the html page that is from the game. I need to have the javascript get 432|608 and assign x=432 and y=608 in this case, although those number change, the place in the table that that they are displayed do not change.
<td>Coordinates:</td>
<td><a href="game.php?village=19392&s=map&x=432&y=608">432|608</a></td>

Is it possible to read the contents of a table cell. I have the below table and would like extract the value of the first cell. The first cell will always be a hyperlink so I guess I only need the contents between the "<A>" tags. So the first row should return ""434235". How can I do this.code...

onto the webpage. How would it be possible to use javascript to read
the filname (and the dimensions) of the loaded image (something I can
get by right-clicking the image with the mouse, but it is not given in
the source of the page).
I want to find any <!-- --> comment tags in a page and then read the contents. I would also like to distinguish between those in the body and those elsewhere in the HTML document.What do I use to get an array of these elements?
View 10 Replies View RelatedI can read the contents of an iframe:
HTML Code:
var iframe = document.getElementById("message");
var iframeContents = iframe.contentDocument.body.innerHTML;
var txtarea = document.getElementById('message2');
txtarea.value = iframeContents;
This will read the contents of an iframe, and write it to a textarea.
iframe is editable, and content is entered by the user. Still, this works.
But, below code is not working. Trying to put some content to an iframe, with the same innerHTML method above. It returns no errors or warnings. Even last alert() displays "<div>lorem ipsum</div>", but iframe is empty, it displays nothing..
HTML Code:
var textContent = "lorem ipsum";
var iframe2 = document.getElementById('message');
iframe2.contentDocument.body.innerHTML = '<div>'+textContent+'</div>'
alert(iframe.contentDocument.body.innerHTML);
I am currently working on an announcements portlet for a dashboard that my team is creating. What is desired is to be able to have this portlet access a stored text file (file can be edited so content is subject to change) that will have all the information needed for these announcements. The JavaScript will then write it into a html file. I am a novice at html, and javascript;
View 5 Replies View RelatedI have an external file, TestVar.js with a single line.
NewsA("This is a test.","test.pdf","TEST")
Within my HTML I wish to use the array variables from TestVar.js, but
can't seem to get them loaded for use. The following is what I have,
but doesn't work. If I directly place the NewsA array in the script
instead of trying to call it from the js it works just the way I want
it, but I really need the external file. What am I doing wrong? Code:
While writing a look up for internet terms script for a site, I found the script will not read the second value in this array, I could make wl[1] a null value but would like to know what is happening if possible. All of the other elements seem to be ok!
function search(){
wl = new Array()
wl[0]="applet - An Applet is a small application etc";
wl[1]="Bug? - Null but why";
wl[2]="cgi - CGI or Common Gateway Interface allows etc";
wl[3]="browser - A Browser is etc.";
myWord=document.theForm.txtWord.value;
myWord = myWord.toLowerCase();
for(c=0; c < wl.length; c++){
currentWord = wl[c].split(" ");
alert(c + " MyWord " + myWord);
alert(c + " Current " + currentWord[c]);// The alert box = 'Current -' when wl[1] is read.
}

What i want to know is how to read the value stored in an array to a textbox though I have a second array which is contianed in dropdowns with a for loop iterating
ie item and price arrays
So i want it if item [position] then price [position] is called to the textbox how do i do this so that it iterates through the values using a for loop as i am meant to iterate through and not hardcode in values.
I was wondering if its possible to add contents within a div to a javascript array. Something like this code...
View 2 Replies View Relatedi have a table of images, with onmouseover,onmouseout and click events. The user can select and deselect an image. When an image is selected, the image scr changes.
Then the user can confirm his selections and redirect to another page for the checkout process. When he returns to the first and initial page, i want his selections to have a different image (lets say confirmed.gif).In other words to save his selections in a cookie and return them by changing the images so that they wont be available for selection.
In order to find which images are selected and store them in an array i can use the following loop:
function getSelected(){
var myArray = [];
var images = document.getElementsByTagName("img");
for (i=0;i<images.length;i++){
[Code]....
How i can save that array with the images tittles in a cookie, so that when the initial page loads i can find which images to change and then change the image.src to confirmed.gif ?
I have a program where you enetr the name and price of books and it totals up the cost but i cant seem to get the total to work
<html>
<head>
<title>Arrays</title>
<script type="text/javascript">
[Code]....
Code:
<label for = "Service">Service Required</label>
<select id= "Service">
<script type="text/javascript">
for (var i=0; i<service.length; i++)
{document.writeln("<option>" + service[i] + "</option>");}
</script>
</select>
Using this creates the dropdown box though I want to take
Code:
var service = new Array();
//log book services available
service[0] = "12 month log book service";
service[1] = "18 month log book service";
service[2] = "24 month log book service";
service[3] = "30 month log book service";
service[4] = "36 month log book service";
service[5] = "Other minor service";
service[6] = "Other major service";
var price = new Array();
//prices log book services available
price[0] = "255";
price[1] = "285";
price[2] = "530";
price[3] = "255";
price[4] = "285";
price[5] = "285";
price[6] = "540";
This is to show the expected data at this point in time though I may add or remove elements so I want the code to be flexible a= ie iterative so I want to have the dropdown element checked and compare the position of service to get the associated price though they are in two seperate arrays and cannot be changed. Basically I would like to use a if selected value the price at that position is entered into the textbox which is readonly. How would I go about this and I cannot use tools such as jquery to do this. Is there a way to set the select value to the array position on price or something as I have never had to compare two arrays or print a selected value to a textbox.
Using Java script, I need to open and read CSV file. I need to read the column 3 values and store in an array.
View 2 Replies View RelatedI'm using a java-script in a HTML-page. Part of the script is the line:
var limit = 1136 - 1101;

Can I change my JavaScript in such a way that it reads the value of the file
COUNTER.TXT?

I have a project that I need to read some data from an XML file.
Something like:
However, since JS is a client side script so it can't read from client side, is there any alternate way to do this? I am thinking to create a "Data" class, and many "Data" objects, is this an elegant way to do it?
Is it possible to read text from a file and then place it into a div using javascript. I read something on the Internet that I would need to have a server side language such as php or perl to do that. Is that true and if so why is that.
