Just A Quick Question About Line Break	View Content

Hi guys, just a quick question about a line break in JavaScript, where would I do it? If you see I have two math operators here and want them to be on two separate lines, were do I put the line break?

Thanks

Code:

<!doctype html>

<head>
</head>
<body>

<script type="text/javascript">
	var apples = 4+76;
	document.write(apples);
	
	var multiple = 54*11;
	document.write(multiple);
</script>

Hello:

First post here on CS ... I am wondering why my code will not write a new line or line break.

This is fine:
Code:

<script>

document.write("Hello and welcome to javascript!");

</script>

But when I try to put a message on two lines, it does not work. The book I'm reading and several websites have stated the below codes will work, but neither do:
Code:

<script>

document.write("Hello and welcome to javascript! \n");
document.write("It is a tricky language to learn!")

</script>

Code:

<script>

document.writeln("Hello and welcome to javascript!");
document.writeln("It is a tricky language to learn!")

</script>

Am I missing something?

        }
    });*/
        });
function generate() {
    if($("input[name='name']").val().length > 1) {
        fi&nbsp;= $("input[name='name']").val().substring(0,1).toUpperCase();
        var&nbsp;sl = ["Cool "];
        var&nbsp;sl2 = ["Hand "];
        var&nbsp;sl3 = ["Luke",];
 
        {
            var i = Math.floor(Math.random() * sl.length);
            var j = Math.floor(Math.random() * sl2.length);
            var k = Math.floor(Math.random() * sl3.length);
            var nick = sl[i] +   sl2[j] +   sl3[k];
        }
        {
        $("#answer").text("Your Name Is: " +nick);
        $("#answer").fadeIn("slow");
        } ;
    }
}

I would like for it to return:

Your Name Is:
Cool Hand Luke

I want the "Cool Hand Luke" to be on a separate line but I don't know how to put a linebreak in the .text string. Is this something somebody could tell me how to do?

Where in the line:
Code:

$("#answer").text("Your Name Is: " +nick);

Do I put (<br>)

Problem With Line Break

Hi everyone

I am trying to complete some code involving a while loop. It's actually part of an assignment. Although the code is outputting ALMOST correctly there is one thing bugging me.

Here is the code:

Code:

playersScore = rollDie();
	document.write(' Sco  ' + playersScore);
playersPosition = playersScore + playersPosition;
	document.write(', Squa  ' + playersPosition);

indexOfNumber = findIndexOf(playersPosition, specialSquaresArray);

if (indexOfNumber != -1)
{
	document.write(', Ladder to Squa  ' + connectedSquaresArray[indexOfNumber] + '<BR>');
	playersPosition = connectedSquaresArray[indexOfNumber];
	indexOfNumber = -1;

while(playersPosition<80)
{
playersScore = rollDie()
	document.write(' Sco  ' + playersScore)
playersPosition = playersPosition + playersScore
	document.write(', Squa  ' + playersPosition)
indexOfNumber = findIndexOf(playersPosition, specialSquaresArray)

if(indexOfNumber != -1)
{
	document.write(', Ladder to Squa  ' + connectedSquaresArray[indexOfNumber]);
	playersPosition = connectedSquaresArray[indexOfNumber];
}
	document.write('<BR>');

Now, from what I can see I think it's correct. But if if(indexOfNumber != -1) is not executed I get the following:

Sco 2, Squa 2 Sco 4, Squa 6

OK Sco 4, Squa 6 should be on a new line below Sco 2, Squa 2 but no matter where I add the line break, it just will not do it.

Can somebody please point me in the right direction as I am wasting so much time on this silly little problem

Many thanks in advance

EDIT: Ok after further fiddling with the code I entered document.write('<BR>'); in the required place and removed + '<BR>' from document.write(', Ladder to Squa ' + connectedSquaresArray[indexOfNumber] + '<BR>');

This has fixed the problem so I'm happy now. Sorry if I wasted anybodies time. I can't believe I have spent over 7 hours trying to figure this out!

Line Break Issue

Hey guys. I'm working on a "Preview Post" function. When the Preview Post button is clicked, it should reload the page, show the preview above the textarea, then send the text back to the textarea so the user can keep working.

It works until I move to a second line. If there are line breaks they don't get shown in the preview. Also, the text isn't sent back to the textarea.

I have a pair of functions that are supposed to handle the input string. The first function records the input when typing, and the second function picks up the post to print as a preview: You can see what I mean he

Code:

function preview() 
{
  var preview = window.document.postform.inputpost.value;
  window.document.hidden.inputpreview.value = preview;
}

function copypreview()
{
  var copypreview = '<?php echo $_POST[inputpreview]; ?>';
  window.document.postform.inputpost.value = copypreview;
}

Here's how I use them:

Code:

<body onload='copypreview();'>

<?php include("navbar.php"); ?> 

<?php if ($_GET[preview])
{
  echo "<table id=blog><tr><td>";
  echo $_POST[inputpreview];
  echo "</td></tr></table>";
} ?>

<form name="postform" action="submitpost.php" method="post">

Post Title 
<input size="40" type="text" name="inputtitle" id="inputtitle">

<?php include("tagbar.php"); ?>

<textarea onchange="preview();" cols="101" rows="20" id="inputpost" name="inputpost"></textarea>

<div align=center>
<input type="submit" value="Submit"/>
</form>

<form name="hidden" method="post" action="addpost.php?preview=1">
<input type="hidden" name="inputpreview">
<input type="submit" onClick="preview();" value="Preview Post"/>
</form>

Sorry I know it's a lot of code. I tried to make it as readable as possible. Can someone tell me how to fix this?

I thought I might have to find a way to insert <br> tags when the user hits the Enter key, but I could have sworn this thing was working with line breaks before.

Hey guys

I export data from Javascript to Xml file. I have tried several ways to break a line in xml file like document.write("<br/>"); or document.writeln(); etc, but seem it is impossible.

Maybe you can give me a solution......

Look at below:

XML File:
<?xml version="1.0"?>
<DATA>
<Cust>< Select>Debit Card</Select> </Cust ><Cust>[ User>Jan</User ></Cust> <DATA>

I want to break <Cust> from another <Cust>.

Javascript:

function ok_click() {
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");
xmlDoc.async = false;
xmlDoc.load("data.xml");
if (xmlDoc.readyState == 4 && xmlDoc.parseError.errorCode == 0) {
var root = xmlDoc.documentElement;

var e1 = document.getElementById("Select1");
var _account_type = xmlDoc.createTextNode(e1.options[e1.selectedIndex].value);

var e2 = document.getElementById("Select2");
var _user = xmlDoc.createTextNode(e2.options[e2.selectedIndex].value);

var account_type = xmlDoc.createNode(1, "Select", "");
var user = xmlDoc.createNode(1, "User", "");

account_type.appendChild(_account_type);
user.appendChild(_user);

var cust = xmlDoc.createNode(1, "Cust", "");

cust.appendChild(account_type);
document.write("<br/>");
cust.appendChild(user);

root.appendChild(cust);

SaveXML(xmlDoc, "data.xml");
alert("Save!");
}
}

Your help would much appreciated

Line Break In Javascript By Using Createdatarow?

Hi there, I could probably say that I'm some sort of "game developer" as we're modifying an old (but great) hockey title that has html frontend.
http://z6.invisionfree.com/flyermani...showtopic=1864

My JS skills suck though... I have millions of great ideas but because of my very limited skills I run into all kinds of obstacles all the time. This is yet another.

I'd like to redesign the scoring summary layout in the game... so I'm trying to create a scoring line that would show the goal scorers like this:
Atlanta Scoring:
Antropov (1), Reasoner (1)

But currently I'm always getting a line break and I get the scorers like this:
Antropov (1)
Reasoner (1)
etc.

Screenshot:

My code must be sloppy as hell though:

This shows the scorers:

Code:

var sDataHTML4 = ""
	var aHeaderText = new Array(nhlMsg(" Goal assist") , nhlMsg("Team"), nhlMsg("# Assists", true) );
	var aHeaderWidth = new Array( 300 , 120, 50);
	var sHeaderHTML4 = createHeaderRow( aHeaderText , aHeaderWidth );
	for ( var i = 0; i < oAwayLastGame.nNumPlayers; i++ )
	{
	if (oAwayLastGame.aPlayerStats[i].nAssists > 0)
		sDataHTML4 += createDataRow4( oManagerInterface.GetPlayerFullName( oAwayLastGame.aPlayerStats[i].nPlayerID), ( oManagerInterface.GetTeamShortName(oAwayLastGame.nTeamID)), oAwayLastGame.aPlayerStats[i].nAssists) ;
	}
	
	return createTable( sHeaderHTML + sDataHTML + sDataHTML2  + sHeaderHTML3 + sDataHTML4 + sDataHTML3 + sGoals );

Datarow arguments:

Code:

function createDataRow4( args )
{
	var sHTML = "<tr>";
	var nNumArgs = arguments.length;
	for( nIndex = 0 ; nIndex < nNumArgs ; nIndex++)
	{
		(nIndex == 0 ) ? sHTML += "<td class=\"fourthDataCell\">" + arguments[nIndex] + "</td>" :sHTML += "<td class=\"data2\">(" + arguments[nIndex] + ")</td>"

	}
	return sHTML += "</tr>";
}

What the heck I have to do make the scorers to show all in the same line? Does "create datarow" automatically define them in one separate row? The answer must be simple but I simply can't figure it out... I have tried to Google this for days now.

Thanks.

Hello Coding Forums,

Quick Cookie Question

using jquery and cookie plugin.

i made a popup window. when the user clicks on a check box the window closes, forwards them to a new page, and then sets a cookie.

i need it so that when they go back to the original page (where the popup came from) if the browser detects the cookie then the popup does not occur. I do not know why this does not work because when I alert the value of the cookie out, it gives me the correct number. something must be wrong in my logic ?
code on the base page.
Code:

 <script type="text/javascript">
var test123 = $.cookie('FBCheck');
		
if ( test123 != 1212){ 
function popup(Site)
{
window.open(Site,'PopupName','toolbar=no,statusbar=no, location=no,scrollbars=no,resizable=no,width=350,height=500')
}
}

</script>

code on popup (both files are in same directory)
Code:

$(document).ready(function() {
	$("#Cbox").click(function() {
	window.open ("http://www.google.com", "Google");
	window.close();
	$.cookie('FBCheck', '1212', {expires: 365, path: '/'});
	
	
	
							});
						   });

The jquery source is installed as is the plugin.

Thanks so much for your help in advance!

Hi,
Ever seen on the iphone where you have to slide the slider across the screen to unlock it? I have a duplicate of this using javascript but no matter what I try I cannot make it redirect. I want the page to be redirected after the slider has gone to the other side.

Heres the HTML Code:

<!DOCTYPE html>

Code:

$(function() {

	$("#slider").draggable({
		axis: 'x',
		containment: 'parent',
		drag: function(event, ui) {
			if (ui.position.left > 550) {

		stop: function(event, ui) {
			if (ui.position.left < 551) {
				$(this).animate({
					left: 0
				})
			}
		}
	});
	
	// The following credit: http://www.evanblack.com/blog/touch-slide-to-unlock/
