JavaScript - Can't Write To A Textarea
Hi,
Nothing will display in my textarea after pressing an input number which have to seen on the display. The code is from a simple calculator <form action="#" method="get" onsubmit="return false"> <p> <textarea disabled="disabled"></textarea> </p> <div id="calculatorButtons"> <p> <button onclick="calculatorNumber(1)">1</button> <button onclick="calculatorNumber(2)">2</button> <button onclick="calculatorNumber(3)">3</button> <button onclick="calculatorOp('+')">+</button> </p> <p> <button onclick="calculatorNumber(4)">4</button> <button onclick="calculatorNumber(5)">5</button> <button onclick="calculatorNumber(6)">6</button> <button onclick="calculatorOp('-')">-</button> </p> <p> <button onclick="calculatorNumber(7)">7</button> <button onclick="calculatorNumber(8)">8</button> <button onclick="calculatorNumber(9)">9</button> <button onclick="calculatorOp('*')">*</button> </p> <p> <button onclick="calculatorNumber(0)">0</button> <button onclick="calculatorOp(',')">,</button> <button onclick="calculatorClear()">Clear</button> <button onclick="calculatorCalculate()">Calc</button> </p> </div> </form> function calculatorNumber(i) { document.form.getElementById('textarea').innerHTML = i; } What is the right way to refer to the textarea? Similar TutorialsThis seems like it should be easy but I can't figure it out. I am trying to set up a drop down list to interpret an abbreviation and to also hyper link to a site about the object. I want it to stay in the <textarea> and not write a new document but it is the only way I have been able to get a hyperlink. Any suggestions would be appreciated. Here is my HTML and JS HTML: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

}
</style>
</head>
<body>
<fieldset style="width:410px; height: 250px;">
<h2>DESCRIPTION BY ABBV</h2>
<form name = "listNAME">

function findMEAN(){
var abb = document.listNAME.abbWRD.value;
if (abb == "AIR"){
abbs = ("AIR Commercial Real Estate") ;
abbslnk = document.write("" + abbs.link("http://www.airea.com") + "");}
else if
(abb == "CCVT"){
abbs = ("COUPLING CAPACITOR VOLTAGE TRANSFORMER") ;
abbslnk = document.write("" + abbs.link("http://www.abb.com/product/db0003db002618/c12573e7003302adc1256ffd001d1256.aspx") + "");}
{
var result=document.getElementById("resultbox");
result.value = abbslnk
}
}
Thanks in advance. I'm a total noob who decided to learn som web programming, I hope it's okey to post such questions here. I've written a script to learn how to fill in a value into a textarea by a button click. (See below.) I get it to show the selected number of each button, however the numbers just flashes and disappers right away. I want it to stay in the textarea. How do I do that and why does this problem appear? Head section <script type="text/javascript"> function calculon(i) { document.forms['siffror'].elements['test'].value = i; return; } body section <form name="knappar"> <input name="sifferknapp" type="submit" value=1 onClick=calculon(this.value)> <input name="sifferknapp" type="submit" value=2 onclick=calculon(this.value)> <input name="sifferknapp" type="submit" value=3 onclick=calculon(this.value)><br /> <input name="sifferknapp" type="submit" value=4 onclick=calculon(this.value)> <input name="sifferknapp" type="submit" value=5 onclick=calculon(this.value)> <input name="sifferknapp" type="submit" value=6 onclick=calculon(this.value)><br /> <input name="sifferknapp" type="submit" value=7 onclick=calculon(this.value)> <input name="sifferknapp" type="submit" value=8 onclick=calculon(this.value)> <input name="sifferknapp" type="submit" value=9 onclick=calculon(this.value)><br /> </form> 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;
?>
<tr>
<td bgcolor="FAFAF6" class="small" valign="top">Class <? echo $i; ?></td>
<input type="hidden" name="<? echo "classid[]"; ?>" value="<? echo $i; ?>">
<td bgcolor="FAFAF6">
<textarea name="<? echo "specification[]"; ?>" COLS="50" ROWS="6" class="small" wrap="virtual" tabindex="<? echo $i; ?>"><? echo $ClassDesc2;?></textarea>
<input type="button" value="Reset" onclick="window.reset();" name="reset">
</td>
</tr>

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! I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed. So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write. Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script. Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script. Any suggestions, I'd greatly appreciate it. Or even if you've encountered a similar problem, and know that it just isn't possible in IE or Opera, that would be fine too. Thanks in advance! Hi i have a function (i wont write it out coz it is too long!) but after i have done the main calculations within this function i wont to display some of the variables in a table. i have writen: document.write( <table border="1"> <tr><td> Value 1 </td><td> document.write(a); //here * </td></tr> </table> ); were it says "here *" i wont to write within the table variable a (which i have defined properly in the function). However, as i have already written document.write it actually displays the text "document.write(a);" instead of the value for var a. Help asap please as it in for school soon! Thanks in advanced :D 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 hi everybody,i ve given a task to write a java script calculating a root using bisection method,i've tried to write it on my own but i dont have a clue how to do that .i suppose to find the root using this EQUATION x^7-32=0.i would appreciate any help!
Hello, I'm new to Javascript. I know how to make a script that when you click on a button it changes a variable. I also know that with document.write I can express this variable but I do not know how to refresh document.write! For example, if I have a var car =3 and when I click on a button car++ (or increases by 1 so it becomes 4 then 5 and so forth depending how many times you click the button) and I write document.write (car), it only shows the 3 and no matter how many times I click on the button, the 3 doesn't change. How can I get the document.write to show the updated variable? Thanks! So I want to have a button that when I click it will change this variable and that number will change live on the page. What is an alternative to document.write? I know I could use <p> in html </p> I would like to use JS though. I hope you can understand my question. I am 14yo and this is not for homework. I just wanna try and learn JS. I read document.write can cause me problems. But all I ever see is: <script type="text/javascript"> document.write("any words"); </script> what alternate could I use? I would like to know what is the difference in writing Javascripts in the head scetion of a HTML page and writing it in the body section. Can I divide the scripts between the two sections ? For example some script in head section and some in the body section. I am writing window.open ('first.htm') in the head section, plus some form validation script. I want this first.htm to be displayed once at startup. But everytime I click the submit button and form validation script gets invoked, this window pops up. How do I avoid this ? mrk98 Within my Flex application I write stuff to the browser via a javascript document write. Is there a command to send to indicate I want to close that stream? When I send the command the rotating indicator keeps running indicating the browser is still expecting some stuff. If I click the stop button on the browser it stops spinning and the stuff I sent (an xml stream) becomes available. As this is an automated process, there is no person to hit the stop button. how would you make when you press a button it writes somthing in a input box.
Is there anyway in JS to capture the user's IP address and then write it to the variable, ip_addy?
this had to do wiht HTML and javascirp thow would you make a function that wirtes somthing in a input box(sorry about messy ness i wasint looking)
hey ppl. i am new here. looks like i will do some Js for years i have a div called "farmacias" inside the content div i want to write something in the div but this is not working document.getElementById("farmacias").innerHTML='ola' anyone knows why? Is it possible to limit a textarea input with a max amount of letters? So if the form said 1,000 character limit.
