JavaScript - Clearing Textarea Default Text
I need to clear the default value from a textarea when a user clicks on the textarea and then replace it if the user clicks away from the textarea without modifying it. I have managed to accomplish this with the textfields in my forms but I am struggling to get the textarea element to mimic this behavior.
Here is the script I am using: Code: addEvent(window, 'load', init, false);
function init() {
var formInputs = document.getElementsByTagName('input');
for (var i = 0; i < formInputs.length; i++) {
var theInput = formInputs[i];
if (theInput.type == 'text' && theInput.className.match(/\binput\b/)) {
/* Add event handlers */
addEvent(theInput, 'focus', inputText, false);
addEvent(theInput, 'blur', replaceDefaultText, false);
/* Save the current value */
if (theInput.value != '') {
theInput.defaultText = theInput.value;
}
}
}
}
function inputText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == target.defaultText) {
target.value = '';
}
}
function replaceDefaultText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == '' && target.defaultText) {
target.value = target.defaultText;
}
}
HTML: [HTML] <form action="#"> <fieldset> <legend></legend> <input type="text" value="Your Name" id="name" class="input" /> <label for="name">Name Required</label><br/> <input type="text" value="Your Email" id="email" class="input"/> <label for="email">E-mail Required</label><br/> <input type="text" value="Your Website" id="website" class="input"/> <label for="website">Website</label> <textarea rows="15" cols="71">Your Message Goes Here.</textarea> <input type="submit" value="Submit Comment" class="button" /> </fieldset> </form> [/HTML] I am really just trying to get this form to behave the way all other forms on the internet work- where text clears when a user clicks on a form element and replaces itself if the user doesn't enter new text. I have it working on the text field but no the textarea. Help! Similar TutorialsHey guys, First shot at JS so please be gentle! I'm trying to get this script to clear the default value of my input elements on focus. It works well the first time, however, if a user inputs some fresh text, selects something else, then selects the same input element again, it will clear the text they entered. Make sense? Here's the script (thanks in advance!!): Code: <script language="JavaScript">
function clickFocus(input){
input.className = 'focus';
if (input.value = input.defaultValue){
input.value = '';
}
}
function unFocus(input){
input.className = 'entered';
if (input.value == ''){
input.value = input.defaultValue;
input.className = 'normal'
}
}
</script>
<form action="confirmation.php" method="post" enctype="multipart/form-data" name="form" id="form" onsubmit="return checkForm(this)">
<input type="text" name="name" value="Name" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="email" value="Email" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="subject" value="Subject" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<textarea type="text" name="message" onfocus="clickFocus(this)" onblur="unFocus(this)" rows="5">Message</textarea>
<input class="submit" name="submit"type="submit" value="Send Message" />
</form>
Hi- I have a table with numerous textareas that I am able to clear once - the first time the textarea is clicked the default value is cleared and everything is OK. However, at a certain point the user might press a 'Clear' button linked to a function I wrote to reset the values back to the defaults. At this point clicking into the textarea does not clear it. Below is a typical textarea: Code: <textarea rows= "2" cols="15" class="Klabel" id="ta5" onfocus="this.value=''; this.onfocus=null; setbg_color('ta5','#EFA746')" onchange="setbg_color('ta5', '#EBF5FF')">
Type a label
</textarea>
Below are the relevant functions. The Clear function mentioned above just runs 'setbg_color' and 'set_value' for each textarea and sets them to the defaults. Code: function setbg_color(id, color){
document.getElementById(id).style.background=color;
}
function set_value(id, celltype){
document.getElementById(id).value=celltype;
}
Is there anyway to essentially reverse the effects of the this.onfocus=null; statement? I tried something like this.onfocus=true; but that didn't work. An update - I haven't answered the reversing null question but an acceptable solution is to reload the page from within javascript as per http://www.mediacollege.com/internet...ge/reload.html Thanks -Jim ps - As part of my research I came across this http://mvied.com/blog/unobtrusive-input-clear-focus/ which does a smoother job of clearing the textareas but does not solve my question. 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! This is some of the script that I have and it works well. The story is that I have a drop down list and depending on the selection a different set of text is displayed below the list. Code: if (Val == "general")
{
document.getElementById('Link0').innerHTML="<font size=2><a Href='http://www.web1.com/'>web 1</a>"
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web 2</a>"
However when the selection runs this part of the code:- Code: if (Val == "duties")
{
document.getElementById('Link0').innerHTML=""
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web3</a>"
The "web 3" text is placed under where the 'Link0' text would have been if there had been some. So basically what I need to do is set the 'Link0' text to nothing and have the 'Link1' text sit in its place. I know I could just put the 'Link1' text in the 'Link0' element but I have other controls on the screen that mean I need to run it as it is. I hope that is clear, cheers Daniel. Hi there, this is my first post. I'm very new to javascript and have been programming a "beer counter" that simply counts +1 into a text object after every click. After I got this to work I copied the code in order to make a clear button / function. I've been having problems, even though the code seems to be identical. This is likely an obvious question, pardon my inexperience. <html> <head> <title>Beer Counter</title></head> <body><script language="Javascript"> var beers = 0 var output ="" function beer() { beers = beers + 1 output = document.getElementById('output') output.value = beers } function clear() { beers = 0 output = document.getElementById('output') output.value = beers } </script> <input type='button' value='Crush' onclick='beer()'; /> Beer count:</input> <input type='text' id='output' name='output'; /><br/> <input type='button' value='Clear' onclick='clear()'; /> </body> </html> Hi, my code below shows 2 radio buttons, when you click on one, it shows the content from a div, I would like to show the content of the checked radio button by default, at teh moment, they don't show any content until they are clicked!

Hi, I'd like to use the jQuery validation plugin as seen on the following example: http://docs.jquery.com/Plugins/validation#Example But it doesn't work properly if I use inline/in-filed labels. Any help is appreciated! Rain Lover I would like to ask is it posible to add text from a text file to a text area on a page.. Philp if you read this i am not asking for a javascript code i am asking wether or not it can be done. P.s if your a nice person like philp is not and you want to private message me if you have one Hey guys, I have a question about sending text to a textarea. What I want is, if I click on a button, a text has to be sent to my textarea, which I obtain from my mysql database. This last thing I can do myself, but I do not know how to send the text to my textarea. I don't know nothing from AJAX yet, so I think it can be done with AJAX, but also with javascript I guess. Could someone point me in the right direction? Thanks! End result: I want to have buttons along the top of a textarea which will be used to add tags around highlighted text / the text curser thingy. (Basically it will be an edit box like the I am using now to make this post). Problem at the moment: I want to reference the var to use in the function. e.g. Code: function addtext(id) {
var al = "<div style=\"text-align:left;\"></div>";
document.myform.outputtext.value += id;
}
"id" will be defined as "al" in the HTML onclick function, I want this to use "var al" where it says ".value += id;". HTML: Code: <form name="myform"> <textarea name="inputtext">Type Here</textarea><br /> <textarea name="outputtext"></textarea><br /> <input type="button" value="Add New Text" onClick="addtext(al);"> </form> If I do this: onClick="addtext('al'); Then "al" is just written in the output box as it is sending a string, correct? If I do this: onClick="addtext("al"); / onClick="addtext(al); Then nothing happens... Reason I want to do it: Well, because I want to have multiple var's instead of a load of functions... Problem 2 (To fix after first problem): I also want the var to add around the highlighted text, not after all of the text. How do I resize a textarea to a certain length for text without the scroll bar, it this possible with CSS or do I have to use jQuery?
Hey guys, I am wondering how to send text to a textarea when clicking on a link. Kinda like when clicking on a smiley or bbcode. I have a script, and it works, but only when the text to insert is on one line. Here is the code: Code: <script>
function sendtext(e, text) {
e.value += text
}
</script>
Code: <img onClick="sendtext(document.myform.mytextarea, ':)')" src="smiley.gif"> Now I want to use this little script to insert an e-mail template which I am getting from the database into my textarea. Only, it works when the template is on one line, I am using this for my php code, which works, so no need to worry about that: Code: <img onClick="sendtext(document.myform.mytextarea, '<? echo ("$row['mytemplate']"); ?>')" src="smiley.gif">
When the "$row['mytemplate'];" is as follows: Code: Hey, this works It works, but when it's as follows: Code: Hey, it does not work Then it doesn't. So whenever there's a linebreak, it does not work. My question is, can someone help me with this, or a similar script, so I can add a piece of text to my textarea which has linebreaks in it? I hope you understand what I'm asking Thanks in advance for the help. hi all, I have a simple website with 2 Frames, In top frame I have a button that invokes CGI script and internally that CGI script prints info (text) into the bottom frame. Going further we want to print the output coming from CGI into a textarea object in bottom form. I have a function in my CGI script: But ends up printing multiple textarea objects in lower frame. We want to print each line of text into the same textarea object in lower frame. and at the end display a new button. How can we do this using javascript/CGI? I tried the following but not displaying anything. sub print_message { my($message1, $message2) = @_; my $final_message = $message1 . " " . $message2; print <<END_HTML; <html> <head> <form name="myform"> <table border="0" cellspacing="0" cellpadding="5"> <tr> <td><textarea name="outputtext" rows="10" cols="100"> $final_message </textarea> </td> </tr> </table> </form> <style> <!-- a{font-weight:bold;font-family:arial;text-decoration:underline;font-size:13px;} a:hover{font-weight:bold;font-family:arial;text-decoration:none;font-size:13px;} // --> </style> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <a href="main.html" rel="nofollow" target="bottom"></a> <title>CTS Debug Information</title> <style type="text/css"> img {border: none;} </style> </head> <body> </body> </html> END_HTML I created this function in javascript: <script language="javascript" type="text/javascript"> function addtext() { var newtext = document.myform.outputtext.value; var nextLineTextNode = document.createTextNode(newtext + "\r\n"); var logData = document.getElementById("outputtext"); logData.appendChild(nextLineTextNode); logData.scrollTop = logData.scrollHeight - logData.clientHeight; } </script> But when i implemented in my CGI nothing is printed. Thanks!!! I have searched this forum for similar queries & have come up with this http://jsfiddle.net/defencedog/P33FR/ I don't know why this ain't working How can I get the selected text of a textarea with JavaScript? example: Code: <form name="reportForm"> <textarea name="report"></textarea> <br /> <input type="button" onClick="GetSelectedText();" /> </form> Thanks IC Hello there, I am having trouble with a javascript snippet that adds text to a textarea when you click on the link. Problem is that when you regularly type into the textarea, the links no longer add text. Here is the links: Code: <a href="javascript:insertText('<b></b> ','textIns');" onClick="void(0)">Bold</a>
Here is the javascript Code: <script type="text/javascript">
function insertText(val,e) {
document.getElementById(e).innerHTML+=val;
}
</script>
Any ideas or suggestions? I searched about this problem over Internet and found the same result many times, I found this example on stack overflow but this example didn't work in my project; I am making a toolbar with buttons that insert HTML tags around the selected text in a <textarea>, this exemple didn't work because when the user click on a button the selected text won't be selected anymore because <textarea> loses focus and selected text will be unselected, I am targeting Firefox and compatible browsers so you don't need to give me the IE code; jQuery codes are accepted; so, have you any idea?
