JavaScript - Inserting A Linebreak To A Textarea
Hi,
I am sending some information from one page to another using Form and Link. This generates a string of text in the receiving url, which I am extracting and displaying in a textarea. How do I insert a linebreak in the javascript code? With this line of code: document.getElementById("Requirements").value = "Top line: "+ topline + "Your breakfast contains: "+ menuitems; everything that is being returned is running together. I need it to run on separate lines. I can't control it with box width because the entries will vary on each occasion. I assume there is an escape character like in php or a break tag like in HTML, but I don't know what it is! Any help appreciated. Thanks, Tim Similar TutorialsHi All, I am new to javascript and actually I need to insert the data into a textarea from a text file when the user loads the browser.. and I am using this program to do it..but its throwing error 405, I dont know whats the problem..can any one please check the code or give me some code to do the same funtionality. Quote: <script type="text/javascript"> function getfile() { xmlHttp = GetXmlHttpObject(); if (xmlHttp == null) { alert("Browser does not support HTTP Request"); return; } var url = "${pageContext.request.contextPath}/static/files/email1.txt"; xmlHttp.onreadystatechange = stateChanged; xmlHttp.open("POST", url, true); xmlHttp.send(null); } function stateChanged() { if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete") { var emm = xmlHttp.responseText; alert(emm); } } function GetXmlHttpObject() { var xmlHttp = null; try { // Firefox, Opera 8.0+, Safari xmlHttp = new XMLHttpRequest(); } catch (e) { //Internet Explorer try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; } </script> can one give me some idea regarding this. Thanks in Advance, Best Regards, Rajasekhar. Hi i have a problem, i've been trying to fix this for the whole day pls see my code below Code: for ($o = 0; $o <= $totalclass; $o++)
{
for($i = 1; $i <= 45; $i++)
{
if ($_SESSION['classification'][$o] == $i)

$sql2="SELECT ClassDesc FROM tblclass WHERE ClassID = '$i'";
$result2=mysql_query($sql2);
// If successfully queried
if($result2)
{
while ($row2 = mysql_fetch_assoc($result2))
{
$ClassDesc2 = $row2['ClassDesc'];
}
}
//echo $ClassDesc2;

i've trying to create a button or image to reset one textarea (from whole array) and so far i've been unsuccessful. i've seen this on other website and i know it is possible to do this, pls help! Hello there . Here is my simple code Quote: <html> <head> <script> function addText(){ document.getElementById("textarea").value+=document.getElementById("text").value+'\n'; document.getElementById("text").value=""; document.getElementById("text").onblur=document.getElementById("text").value=" Your Message..."; } </script> <style> #textarea{background-color:#F3F3F3; } </style> </head> <body> <form> <TEXTAREA id="textarea" COLS="80" ROWS="20" ></TEXTAREA><br/><br/> <input type="text" id="text" name="text" value=" Your Message..." onclick="this.value=''" size="96"> <input type="button" value="Send" name="submit" onclick="addText()"> </form> </body> </html> My problem is I dont know what to do iorder to make my send button to push the text entered in the text field from bottom to the top (not from the top to the bottom) Hi all, I'm loading external xml and displaying specific tagged elements in a textarea. It works fine in IE because I can turn the variable object into text with a simple object.text property, but in Firefox (using the serializeToString method), the object appears in my textarea tags and all. The code looks something like this (this is just a dummy script - imagine the xml is already loaded into the object xmlDoc ): Code: function writePage(){
document.write('<textarea name="inputText">'+myText+'</textarea>');
}
function xmlIsLoaded(){
if(window.ActiveXObject){ //tests for IE
myText = xmlDoc.getElementsByTagName("desiredTag")[0].text;
} else { //tests for FF
myText = (new XMLSerializer()).serializeToString(xmlDoc.getElementsByTagName("desiredTag")[0]);
}
writePage();
}
What am I missing here? I've tried toString, textContent, innerText, childNodes - just about everything I can think of to get just the text w/o the tags from the xml for the FF version. Any thoughts? ~gyz So my goal was to insert a mini ICO image (of an R) and have it be a link to an external news page for each individual player on a fantasy team. The code below gets the proper link to each player and inserts the image and corresponding link one at a time though a couple different functions. I have inserted the IMG successfully (see attached), but I am having issues with the link. There are times when the images load accurately with the correct link and others when some of the 'href' elements say undefined. And it isn't consistent either, as to imply that it is a specific coding error. It is completely random and sometimes they are even all correct. Could this have something to do with the asynchronicity of the GM_xmlhttprequests and the loop? If so, is there some way to get around that? This is the bottom of the code which gets fed an array teamURL with all the proper URLs. All of the variables and arrays have the correct information, as they have been checked and double checked. It is almost as if I need a way to slow down the loop to let it do its thing... if that makes any sense. Code: var count = 0;
var item = 0;
for (var k=0; k< myPlayersArray.length; k++)
{
GM_xmlhttpRequest({
method:"GET",
url:teamURL[k],
headers:{"User-Agent":"Mozilla/5.0","Accept":"text/xml"},
onload:function(response){findInfo(response);}
}) ;
}
var allElements = document.evaluate("//*[contains(@href, 'http://sports.yahoo.com/nfl/players/')]", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,null);
var baseRotoworldURL = 'http://www.rotoworld.com';
function findInfo( response )
{
var doc = document.createElement( "div" ) ;
doc.innerHTML = response.responseText ;
//Get appropriate td data on the rankings page
var teamPageList = document.evaluate("//a[contains(@href, 'player')]",doc,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var m=0; m<teamPageList.snapshotLength; m++)
{
if ((teamPageList.snapshotItem(m).innerHTML.toString()) == (myPlayersArray[count].toString()))
{
var playerHTML = teamPageList.snapshotItem(m).parentNode.innerHTML;
var match = playerHTML.match(/\/nfl\/\d{1,10}\/[a-z]+\-[a-z]+/);
var playerURL = baseRotoworldURL +"/recent" + match
break; //loop until you get a hit
}
}
addGameLogIcon(allElements, playerURL);
count++;
}
function addGameLogIcon(allElements, playerURL) {
var thisElement;
var rotoworldLink;
var rotoworldLinkGraphic = "data:image/gif;base64,"+"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";

How would I insert bbc code around selected text in a textbox like it is in this forum? I'm quite new to javascript, so please try to explain it simply Thank you, ~AngelMare I have a table with two rows and 4 columns, the first cell has rowspan of 2. How do I insert something into the first cell only? How can I get the cell index of the first cell?
Hello. I have two javascript problems. 1). I have a java script that displays 'What's On Air Now' and 'Today's Schedule' which are located in a 'Resources' folder on our website. I have been using Namo Web Editor for several years but, after many problems, I bought WebPlus X4 from Serif Applications. It's a very good program but I'm having severe problems inserting the Javascripts mentioned above. With Namo, I just had to add: "<script type="text/javascript" src="resources/onair.js"> and the same for 'Today's Programs':"<script type="text/javascript" src="resources/schedule.js">". with WebPlus X4, I've had no luck after trying numerous times and requesting help from Serif who would not help. I would be grateful if anyone could help me, please. Thank you. PS: I have attached the text version of the scripts for you to have a look at.
Hello, I know very little Javascript, so the answer to this is probably VERY simple :-) I have some javascript working out the current date for me. I want to output this date into the value of an input field in a form. My javascript to output the date is: Code: <script type="text/javascript">
<!--
var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFullYear()
document.write(month + "/" + day + "/" + year)
//-->
</script>
And I'd like this to output in the value of the input field below: Code: <input type="hidden" name="date" value="js date to go here"/> I've tried using script tags and document.write, but it messes up my HTML and I'm not sure what exactly it is that I'm doing wrong!! Sorry for the silly question... Thanks for your help Nicky First off: I know nothing of Javascript (or much of any coding really), but I expect this to be simple for someone experienced, although it was (suprisingly) hard to figure out, for a lousy Googler like myself; so here I am. I have a function that generates an URL to an image, as so: Code: function todaysDate() {
var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
window.location.href = "http://www.ecample.com/generator.aspx?format=png&month="+month+
"&day="+day+"&width=320&height=480"
}
I get the image displayed fine in a new window, but I need it to open in a <div> or object, iframe, something I can place under my <div>-based header, when a button is pressed from my menu. Code: <div id="image">
<div class="header">
<a href="#" class="back">back</a>
<h1>Title</h1>
</div>
I WANT IT HERE!
</div>

Here is my code.I left out my sorry efforts of influencing the textarea. Any suggestions? I sell products on amazon. and ASINs are Amazon Identifiers for products. So If I want to check out my product pages I have to go to "www.amazon.co.uk/dp/ "I have to put an ASIN here" . If I can put everything together in the text box and hit go it should take me to the first page(first ASIN). Here is a sample ASIN B004Z2QORW I have the code below but I somehow cant get it to work. Please help. I haven't assigned anything to the go button. I will put a list of ASINs in the text area and the iframe should concatenate the value from a row to the hardcoded URL and when I click next it should concatenate the value from the next row; when I click previous the value from the previous row. Code: <HTML>
<Head>
<H1 align="center">Detail Page Lookup using ASINs</H1>
</head>
<body>
<textarea rows="10" cols="20" value="">
ASINs here

hi I am trying to create a textarea. There is a default text inside textarea. so when user clicks inside textarea then submit button appears and default text disappears and when user clicks somewhere else or outside textarea then it gets back to original state i.e, default text appears back and submit button disappears. here is what i did sofar. in this code when i click inside textarea then submit button does appear but text does not erase and when i click outside then button remains in sight. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

on html i named my textarea as features, is the code below correct cause is does not validate. if (document.forms.myform.features.value == "") is it possible to make a textarea resize with text? so if e.g the text overflows, the text-area is automatically resized so that there's no scrolling? It needs to resize automatically as the user is typing (more or less), he/she shouldn;t click on any buttons to resize it
so I am creating a silly word ;irate word interpreter page, and I need some logic behind how to add text to a textarea each time I click on a button. Each time the user clicks on the button, the value is inserted into the text area. You should be able to click on multiple buttons to add to the last text that appears. Then I have a delete translation button when I want to clear the textarea field. A good example would be if the user clicks on the button with the value "sir", than "matey" will appear in the textarea. Now, if the user clicks on the button with the value "your", then "yer" will come up after matey. It's like creating a sentence on your own, and then deleting it when your done. Code: <body> <div id="page"> <div> <img style="float:left" src="slue.gif" width="205" height="190" alt=""> <div> <h1>Pirate Translator</h1> <p>Simply click on the buttons to translate words and/or phrases from English to pirate talk</p> </div> </div><br /> <hr /> <form name="pirate"> <div> <fieldset> <legend><b>Greetings:</b></legend> <input type="button" id="greeting" value="hello" /> <input type="button" id="greeting" value="pardon me" /> <input type="button" id="greeting" value="excuse me" /> <input type="button" id="greeting" value="" /> <input type="button" id="greeting" value="" /> <input type="button" id="greeting" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>People:</b></legend> <input type="button" id="people" value="sir" /> <input type="button" id="people" value="madam" /> <input type="button" id="people" value="miss" /> <input type="button" id="people" value="stranger" /> <input type="button" id="people" value="officer" /> <input type="button" id="people" value="" /> <input type="button" id="people" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Questions:</b></legend> <input type="button" id="question" value="where is" /> <input type="button" id="question" value="can you help me" /> <input type="button" id="question" value="is that" /> <input type="button" id="question" value="how far is it to" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Articles:</b></legend> <input type="button" id="article" value="the" /> <input type="button" id="article" value="my" /> <input type="button" id="article" value="your" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Adjectives:</b></legend> <input type="button" id="adject" value="old" /> <input type="button" id="adject" value="attractiv" /> <input type="button" id="adject" value="happy" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Places:</b></legend> <input type="button" id="places" value="restroom" /> <input type="button" id="places" value="restaurant" /> <input type="button" id="places" value="mall" /> <input type="button" id="places" value="hotel" /> <input type="button" id="places" value="pub" /> <input type="button" id="places" value="" /> <input type="button" id="places" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Desires:</b></legend> <input type="button" id="desire" value="I would like to" /> <input type="button" id="desire" value="I desire" /> <input type="button" id="desire" value="I wish I knew how to" /> <input type="button" id="desire" value="my mother told me to" /> <input type="button" id="desire" value="my campanion tells me to" /> <input type="button" id="desire" value="" /> <input type="button" id="desire" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Actions:</b></legend> <input type="button" id="action" value="find" /> <input type="button" id="action" value="take a nap" /> <input type="button" id="action" value="kill" /> <input type="button" id="action" value="hurt you" /> <input type="button" id="action" value="beat you up" /> <input type="button" id="action" value="go to the bathroom" /> <input type="button" id="action" value="" /> </fieldset> </div> <div> <p id="output"><textarea id="task_list" rows="5" cols="130"></textarea></p> <p id="output"><input type="button" id="" value="Delete Traslations" /></p> </div> </div> </form> <script src="js/translate.js"></script> </body> </html> Hi all. I have a textfield on my form problem. My boss wants it as a textfield to keep the field small on the page but still wants to be able to read all of the information that is in the field. What can I do with this?? Can we have change to textarea when he hovers to clicks in it. Any help would be appreciated. |
