JavaScript - Noob Question: Write To Textarea
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> Similar TutorialsHi, 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? This 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">

<textarea id="resultbox" style="width:400px; height:75px;"></textarea>
</fieldset><br>
</body>
</html>
And JS: Code: /**

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 would like to use this code for multiple object on a single page. Code: <SCRIPT LANGUAGE="JavaScript">
function ClipBoard()
{
holdtext.innerText = copytext.innerText;
Copied = holdtext.createTextRange();
Copied.execCommand("Copy");
}
</SCRIPT>
<SPAN ID="copytext" STYLE="height:150;width:162;background-color:pink">
Text of stuff
</SPAN>
<TEXTAREA ID="holdtext" STYLE="display:none;">
</TEXTAREA>
<BUTTON onClick="ClipBoard();">Copy to Clipboard</BUTTON>
The problem is im not sure how to get more than 1 SPAN ID to work with the script. any help would be great! Could someone please change this line so that it respects the global namespace: Code: var selected = students.options[students.selectedIndex].value; The error console is telling me to use document.getElementById but I don't know where to put it. Thanks. Every year or two, I want to do something SIMPLE via JS, and each time it's like i've never been there before I simply want a button to show/hide something on click, and I THINK I'm close, but it's not quite working. Here's what I'm toying with. Code: <html>
<head>
<script type="text/javascript">
function showHide("idName") {
if(document.getElementById("idName").style.visibility=="hidden") {
document.getElementById("idName").style.visibility=="visible";
}
else {
document.getElementById("idName").style.visibility=="hidden";
}
}
</script>
</head>
<body>
<button type="button" onclick="showHide(1)">Click Me!</button>
<div id="1" "style=visibility:hidden;"><p>this is the stuff.</p></div>
</body>
</html>
How do I get the button to make that div (in)visible?? ~Mo Hi all, I sincerely apologise for the noob question. I have search and searched for an answer but to no avail, so I hope someone on here can help. I'm trying to get a fisheye verticle menu working. I've found somethin which fits the requirement he http://zendold.lojcomm.com.br/ifisheye/ and tried to make it work. It just doesn't. I've tried different versions of mootools etc but I think I'm missing something really stupidky simple. I'd really appreciate it if someone could have a look at my temp page (http://www.parkerbs.com/home1.htm) and point me in the right direction. Many thanks in advance. Paul Very new to javascript, so I apologize in advance. I honestly tried to figure this out on my own, and I'm just not able. I'm trying to create a family tree online that has several other related family charts. I want each person's name and birth year to be stored in javascript variables, then I want to be able to just go through the tree, and put the persons name once, and have it put the appropriate name and birthyear in the little boxes that the css is creating. In the js file... I would do this for each family member. Code: var johnname = "John Smith"; var johnbirthyear = "Jan 1 1930"; var janename = "Jane Doe"; var janebirthyear = "Jan 1 1940"; var mikename = "mike wilson"; var mikebirthyear = "Jan 1 1950"; var saraname = "sara johnston"; var sarabirthyear = "Jan 1 1960"; In the HTML file... Code: <div id = "boybox"> <script type="text/javascript"> id = "john"; <!-- this is the only thing I want to have to change --> name = id+"name"; document.write(name); </script> <div id = "year"> <script type="text/javascript"> birthyear = id+"year"; document.write(birthyear); </script> </div> </div> So I thought I had it all figured out. I thought that the above would take the id of John that I added, go to the line that sets the name, add john to the word name, and then document write the variable of johnname from the js file. I know you're laughing at me because of course it instead made the value of name to johnname, then wrote the word johnname in the box. Can anyone point me in the right direction please? ultimately I want to go through and be able to just type the persons name in the html for that box once, and have it update with their appropriate info. Thanks, and sorry for such a rookie question. Hi all, I'm desperately trying to figure out how to "transform" Javascript commands into HTML code. Excuse my noobness but I really know nothing about Javascript. Basically, I have this Google API Search code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>My Google AJAX Search API Application</title>
<script src="http://www.google.com/jsapi?key=CUT"></script>
<script language="Javascript" type="text/javascript">
//<![CDATA[
google.load("search", "1");
function OnLoad() {
// Create a search control
var searchControl = new google.search.SearchControl();
// Add in a full set of searchers
var localSearch = new google.search.LocalSearch();
searchControl.addSearcher(localSearch);
searchControl.addSearcher(new google.search.WebSearch());
searchControl.addSearcher(new google.search.VideoSearch());
searchControl.addSearcher(new google.search.BlogSearch());
// Set the Local Search center point

</script>
</head>
<body>
<div id="searchcontrol">Loading...</div>
</body>
</html>
Now, what I'm desperately trying to do since 4-5 hours is to have the search results between the <div id="searchcontrol"></div> encoded as HTML in the loaded page. Currently, when the page is loaded and I look at the source code, I have the word 'Loading...' in the <div> tags, despite in the normal view there are G results listed. I need those results encoded as HTML for SEO reasons. Researching on this matter I thought the problem could be the OnLoad command, that makes the script load after all the other HTML elements are loaded. But I tried to make it load before all the elements in the page, and the problem persists. How can I solve this? Thanks in advance for any help! Hi, I am looking for an efficient way to go thru all the list items I have in an unordered page and change an attribute. I know I should be able to do it using getElementsByTagName, but I can't seem to get it all working. Can someone please point me in the right direction? Thanks, Thad Hello, I have the following code, which I plan on using the datepicker with, however the code currently hangs up on the script references, as to my knowlege it looks ok, and I can't seem to find anything wrong with it: Code:
<html>
<head>
<script>
function open_cal() {
var str_html = ""
+ "<!DOCTYPE html>"
+ "<html lang='en'>"
+ "<head>"
+ "<meta charset='utf-8'>"

+ "<body>"
+ "<p>Hello test</p>"
+ "</body>"
+ "</html>"
var j = window.open("","CALENDAR","width=200,height=250,status=no,resizable=yes,top=200,left=200")
j.document.write(str_html);
j.document.close();
}

I need your help. Any ideas? Thanks very much in advance, J Hello everyone, I am new I found this site while searching for help with my problem. I'm new to javascript and having a very hard time with the document.write. Can anyone tell me why I'm getting this error? Error: missing ) after argument list Source File: file:///G:/CINS%20157/tutorial.12/case1/clist.htm Line: 79, Column: 58 Source Code: document.write("<th id='sumTitle' colspan='2'>" Summary "</th>"); Then there is an arrow pointing between the S and u in Summary. Even if you could just tell me where to look for help with the answer that would be greatly appreciated. If it helps this is the code it is attached to: <script type="text/javascript"> document.write("<table border='1' cellspacing='1'>"); document.write("<tr>"); document.write("<th id='sumTitle' colspan='2'>" Summary "</th>"); document.write("</tr>"); document.write("<tr><th>" Contributors "</th>"); document.write("<td>"+amount.length+ "</td></tr>"); document.write("<tr>") document.write("<th>"); document.write(Amount); document.write("</th>"); document.write("<td>"+amountTotal()+"</td>"); document.write("</tr>"); document.write("</table>"); </script> Thanks in advance for any help you can give me. I really appreciate it. 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 i got this code which will open a new link in a new window. Code: <script type="text/javascript">
$(function(){
$(".popup").click(function(event){
event.preventDefault();
var href = $(this.)attr("href");
var width = $(this.)attr("data-width");
var height = $(this.)attr("data-height");
var popup = window.open (href, "popup",
"height=" + height +",width=" + width + "");
});
});
</script>
This is the html which it should be targeting. Code: <li><a href="http://www.google.com" data-width="600" data-height="400" class="popup">Latest Posts</a></li> i'm just starting out with js/jq. i dont know what's wrong. thanks for your help. p.s I have explicitly tried the onclick approach where I already gave the function a name followed by () between quotes but same thing happens. The link opens in the same window. please could you help me i am using highcharts and cant get the dates to show at the bottom from mysql over 5 days please could some one help me with this thank you here is the chart database layout code Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

thanks Ok so before you help, just letting you know i'm a BIG noob at coding so please give noob friendly instructions, that would be great thanks I also googled and it didn't help so don't ask. Ok so I'm sure a few people here have heard of the game minecraft? well someone i know (distant relation) showed me something that will track players in the game on servers and i just need help to get it working. He told me i need node js installed to get it working which i don't know how to do (I'm on a mac). I did install python because some people told me i need python to install node js but I'm not sure. So pretty much how do i get node js installed and after that, how do i get the player tracker thing working? heres the github url for the player tracker: https://github.com/koryk/griefguild Much appreciated to anyone that helps! I'm a nooblet so go easy and thank you! I tried posting this: <button type="button" onclick="JavaScript:alert('Let's assume.....')"> <img src="question.jpg" alt="Click here" /> <br />Click for Answer!</button> and it shows the button with the picture, but I am unable to click it. Can you please help me? Thank you in advance. Hey! First off you guys rock! Second im a massive noob - like beyond noob. Ok so heres the deal guys and gals: I use Kampyle (a feedback form thing) and when my viewers click my feedback button a new window pops up and is the form. Like this (plus thats my site if you want to try it): However! theres this site (yes my arch enemy, well were actually two different things and hey i dont even speak their language) and they use the same feedback thing by Kampyle too. But the catch is theirs is inbuilt. something like Lightbox Javascript but for forms/windows. or Facebook's popup notices? so theirs looks like this: This make me ANGRY!!! cause i want that and ive had to ask stupid people cause you guys and gals are way too advance for me... well i am only 17... anywho... WHO CAN HELP ME??? if you want to test the difference between the two forms, my site: that creative corner and click the feedback button. their site:Lyoness and click the feedback button in the bottom right corner. THANK YOU SO MUCH!!! |
