JavaScript - Need Javascript To Write Height Of Text Into Var!?

Hi, I have an idea for putting news articles on my phone to read later when I have time. I'd like to be able to right-click the text of an article and choose "Send to Phone Queue." When I've got a few articles in the queue, I'd like to be able to bluetooth the file to my phone. I know some HMTL and CSS, but I'm very much a novice when it comes to JavaScript. I'm thinking that I probably can't even do a lot of this with JS because of it's limitations (i.e. writing to a file). Will I need to use PHP or Java for writing/bluetoothing the file? I was playing around with extracting the body-text of an article from FoxNews.com. I didn't get very far but you can see where I'm going with it. I welcome any comments, criticisms, etc. Thanks for anything you say, even shooting this down as unrealistic.

Code:

function getBodyText() {

	var divList = document.getElementsByTagName('div');
	
	for ( i=0; i<=divList.length; i++) {
	
		if (divList[i].getAttribute("class") == "entry-content KonaBody") {

                . . .

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">

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!

I heard there is something called XMLHttpRequest that is compatible to all browsers. What does that actually do? Is there something to do with Javascript? Thank you.

how can I write on a picture with javascript?

Hi everyone. I do all of my writing and editing in notepad but can't figure out how to use characters from different charsets in the same script-block.

For example if I wanted to write

Code:

if ( CharInput=="ش" ) { N = 1;}
if ( CharInput=="厜" ) { N = 2;}

I've found the unicode the number for ش is 0634 and 厜 is 539C. But I don't know how to use them. My question is how do I modify the above piece of code so it works in something like notepad?

I can't cut and paste them in because in plain text files like that of notepad the formating is lost and I'm pretty sure html wouldn't allow that anyway.

Thanks for reading

I have am currently taking over as the developer for this web site, and the developer who left the project unfinished wrote a script. What it does is takes posts from vBulletin forums, for instance News posts, and then it grabs the posts by ID and Title and writes the title on the home page of the web site. The problem right now that I have is the test wraps, you can see what I mean here http://www.netcodeilluminati.com/v2

If you look on the left, I want to make the text cut off after a certain amount of characters with "..." at the end as if there is more to the title but you can't see it.

Here is the script:


for (x = 0; x < 5; x++)

{

document.write("<li><div class=\"li_icon\"><img src=\"images/icons/text.png\" alt=\"text\" /></div><div class=\"li_text\">");

document.write("<a href=\"../forums/showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a></div></li>");

}


I was wondering how I could go about doing this.

Thanks for any future help.

write a function that when called will ask the user for a series of numbers to be entered 1 at a time and then calculates their sum,their average,and their average rounded up then output the results.

for example the average of a series of numbers is found by adding the numbers together and dividing by the amount of numbers entered (so the average of 2,5,1 and 7 is equal to (2+5+1+7)/4=15/4=3.75).

how do i write a recursive program to calculate the factorial of a number between 0 and 6.if the user enters a number greater than 6 you should prompt the user again to input another number or -1 to exit the program.how do i write the pseudo code and the javascript code for this program?
i have no idea of how to do this and have been trying to figure it out since the last hour

Is it possible to use JavaScript to locate all of the "smiley sad Icon.jpg"'s and output the location within the table?

Such as A3, and B2.

Thank you in advance.

Code:

Without elaboration plz see my code:
Code:

<body>
<script>
var b="s";
</script>

<button target="_blank" onclick="window.open('http://......php?b="javascript:document.write(b);"&id=2&q=<?php print $_GET['q']; ?>','1','');return false;">xyz</button>
</body>

i don understand why this javascript:document.write(b); doesnt work in url...
i know its simple yet it make my hair out of my head. plz count it..

I've written the following html,
<html>
<head>
<script type="text/javascript">
function createpage(){
var first = document.getElementById('first').value
var second = document.getElementById('second').value
var third = document.getElementById('third').value
var j = window.open('random');
var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>';
j.document.write(new_page);
j.document.close();
}
</script>
</head>
<body>
<form action="">
<p>
First Link: <input type="text" id="first" name="first"/>
Second Link: <input type="text" id="second" name="second"/>
Third Link: <input type="text" id="third" name="third"/>
<input type=BUTTON value="Submit" name="mySubmit" onClick="createpage();return false;">
</p>
</form>
</body>
</html>

With the intention to eventually implement it into a website that "mashes" several URLs together into a tinyurl that, upon being opened, creates several tabs of the content the creator wanted in the single URL. Does that make sense?
In order to best do this I figured a page with a random character string (I haven't yet implemented this part, for now 'random' holds the place of the new page/link) would have to be created that would launch all the tabs and then close itself.

Here's what it should do...
1) User enter 3 URLs into three forms:
First Link: <input type="text" id="first" name="first"/>
Second Link: <input type="text" id="second" name="second"/>
Third Link: <input type="text" id="third" name="third"/>

2) User clicks Submit button that calls "createpage()" function that's declared in the <head>er. The first part of this function declares the links that were inputted as variables first, second, and, third.
<script type="text/javascript">
function createpage(){
var first = document.getElementById('first').value
var second = document.getElementById('second').value
var third = document.getElementById('third').value
3) "createpage()" function then declares a new window named 'random' to variable j (I have random.html stored in the same folder as this project. It is empty.)
var j = window.open('random')


4) Next "createpage()" creates a variable that stores a full page's html code that includes a script that launches each link individually with window.open().
var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>';

5) "createpage()" writes the code (stored in variable 'new_page') to document 'random' with j.document.write(new_page);

6) "createpage()" closes the document.

JavaScript code responsive quiz
I live in turkey.
Can you write me such a code for my site?

Hi Everyone,

I must admit that I'm a newbie in writing javascript.

Can anyone help me with a script that will enable me to display a flash movie on one of my sites.

I will appreciate all your responses.

Thank you.

If the value is negative it should be in red, otherwise it should be in green.
It looks like JavaScript completely ignores the css class. Help please.
