JavaScript - Extract Text And Write To File

Is there a javascript code so that you can disable a textarea but parts of the page can still add to the textarea if your peter i mean about the other javascripts you told me. Sorry if this is confusing just ask me and i will rewrite it

Hi, I was hoping you could help me, I was wanting to write text to the screen but without re-writing the whole screen (e.g. document.write();. I wish to take text and put it in a function, modify it, then display it.
So far I have:

Code:

<script type = "text/javascript">
		function calculate(text){
				var x = "10.0";
				var gpa = text.replace(/0.0/g,x);
				document.getElementById("text").innerText=gpa;				
			}
		</script>
		<p id = text >Your Grade Point Average (GPA) is: 0.0</p>
		<button type="button" onclick="calculate(text)">Calculate</button>

Your help would be really appreciated

I would like to know how to do things.
1. I would like to know how i would code a javascript so if i edit the text inside of either a certain div or in the javascript document itself (which ever would work, would like to have it take the text from a div but not too picky) and then have it write that text in other parts of the same page and other pages by like putting a javascript code in it's place or however you would do it. Basically if i write "hello world" in the div/javascript document, it will write "hell world" in multiple places just from me editing that one part. ok so help with this would be awsome.

My second thing.
2. I would like to take and use some javascript function, such as document.write or what ever to do pretty much the same thing as my first thing as my first problem, but with a div, for like a navigation bar or etc. So any help would be greatly appreciated! =) THANKS!

Hi there,

i have one script which is supposed to pop up a new win and after it does write a piece of text in it. This text comes from inside the HTML area:

Code:

 (script) 

function popupwin(whichOne) {
  var width = 450;
  var height = 490;
  var left = parseInt((screen.availWidth/2) - (width/2));
  var top = parseInt((screen.availHeight/2) - (height/2));
  var windowFeatures = "width=" + width + ",height=" + height + ",status=no,resizable=no,location=no,titlebar=no,left=" + left + ",top=" + top + "screenX=" + left + ",screenY=" + top;
  newwin = window.open("spSelect.html","spSelect",windowFeatures);
  spSelect.document.whichOne.value = whichOne;
}


 (calling part in html) 

<a href="javascript: popupwin(Souvlaki);"><img src="images/orderbutton.gif" width="100" height="20" border="0"></a>


 (new win place where text is supposed to appear) 
<input name="whichOne" readonly="readonly" type="text" class="textfield">

Hello:
I have two input boxes on a form which receive the first and last name of a user. I want to be able to use charAt() to get the first letter in each box and pass it to a third box on the same form. Is this doable? May I request some help?
I was thinking something like the function below would be the starting point --I stand correct, as it is not working.

Code:

<script type=\"text/javascript\">
var str=\"Mossa\";
<!--document.write(str.charAt(0));-->
document.write('<INPUT TYPE=text size=2 VALUE=\"str.charAt(0);\">');
var str=\"Barandao\";
document.write('<INPUT TYPE=text VALUE=\"str.charAt(0)\">');
<!--document.write(str.charAt(0));-->

</script>

Any thoughts!
Mossa

I'm having major pains trying to figure this out. I'm kind of new to Javascript, I need to open a text file from an external server, store each line in an array, then search that array for a certain word (HIGH), and if it exists then write something to the webpage, and if not, write something else. Here is what I have so far:

Code:

<html>
<head>
<title>Test</title>
<script>
<!--
function test(x) {
  if (wxd1txt.readyState === 4 && wxd1txt.status === 200) {  // Makes sure the document is ready to parse and Makes sure it's found the file.
	 var wxd1text = wxd1txt.responseText; 
     var wxd1array = wxd1txt.responseText.split("\n"); // Will separate each line into an array
	 var wxd1high = wxd1array.toString();  //Converting the String content to String
	//var highsearchreg = new RegExp("HIGH");
//var wxd1high = wxd1array[x].search(highsearchreg);
document.write(wxd1high);
	if (wxd1high.search("HIGH") >= 0){
		document.write("HIGH RISK");}
		else {
		document.write("NO RISK");}
		}
}
//-->
</script>
</head>

When added to a webpage, nothing shows up except the "Hi!" and there are no errors in the Javascript Console in Google Chrome. Is this possible with Javascript, and if so, what am I doing wrong or not doing?

Also, I have 2 URLs, one is a text file that has the HIGH text I want for an example, the other is the current file, which shouldn't have HIGH in it (unless the weather in the US turns really bad)

hi, i have looked all over the internet but i can't find anything that works.
All i want to do is simply read from a text file.

Thanks

I'm pretty much lost at javascript, and unfortunately can use php to accomplish this, so here goes........

I have existing html page that includes a Week #. ie, 1, 2, 3, 5.... and so on.

I'd like to be able to have a text, csv, or similar file that I can update on frequent basis that will list a Week # and than custom field of some type. (likely a date or unix time stamp).

Is there a way to open a text file (or csv, etc) in javascript. Than be able to compare and get the correct data?

Off the top of my head, I think its possible, and would involve something like the following?

1. Create a csv file like below

1, this is custom, my other custom
2, some more, and this too
3, and somthing, see spot run

2. Next would be have a javascript open and read the file. You would assign a variable name to each 1st, 2nd and 3rd item of each line.

Than the script would loop through each line until it found a a match of Variable 1 to the Week your looking for. You could then parse out and use the other variables from that line.

Any of that make sense?

I hope to try and experiment some later today or tonight if I can, but javascript is still pretty foreign to me.

Is allowing a button a create a text file a security issue? If so, how do I collect the names of users who have clicked a certain button?

Dear frnd I wanna read on html page , and i have script :

"
[I]<html>
<head>
<script type="text/javascript" language="javascript">
function Read()
{

var Scr = new ActiveXObject("Scripting.FileSystemObject");
var CTF = Scr .OpenTextFile("C:\\123.txt", 1, true);
data = CTF .ReadAll();
document.write("<pre>" + data + "</pre>");
CTF .Close();
}

</script>

</head>

<body onLoad="Read()" >
</body>
</html>
[I]
"

But as its using activex control not allowing in all browser .

Have you any other way with pure js to read the file contains ? or allowing activex in all browser ?

Hello, I am building a web application that has quotes on it. I am planning on having all the quotes stored in a .txt file. A line space would separate the quotes.
Example:
"Blah Blah"

"Idk what blah"

"sure you do"

Would this be using Javascript to pull the quotes from the txt file for use in my page be best? I need it to pull all the quotes. Reason for having it like this, I am also planning on having a random quote page where it just pulls 1 quote instead of showing all of them.

I'm also open to other ideas here!

I have the ability to remotely upload a text file to a folder on my web server.
Periodically during the day I update that file and re-upload it which overwrites the previous file.

I am looking for a script to insert in a webpage that will "get" and display
the current version of that file on page load.

Thanks in advance.
