JavaScript - Resize Textarea To 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?
Similar Tutorialsis 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
Hi, I was wondering how to resize a div containing some text by setting a width and height so it would stretch to fill that area like an <img> tag? E.g. when you set the width and height attribute of an image, it resizes the image to fill that area. I do not wish to send a request to a php script to build an image containing the text since it will be slow and affect the scalability of the web app. Oh, and I would preferably not like to use html5 because it is a requisite that I need compatibility with ie7+ (and firefox/chrome). Thanks, akrylic 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 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. 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. 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! 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?
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 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 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;
}
}

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? 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 Hi, I am having trouble searching for text in a textarea in all browsers. I display formatted text in a textarea with tinyMCE editor. Some of the text contains blanks ('______') which the user needs to find and fill in (usually with a number). I have written a new button on the toolbar of the editor which will find and highlight the blank when clicked. The user will click the button, fill in the text, click the button, fill in the text, etc. In IE the blanks are highlighted just fine. The only problem is: user clicks button and first blank is highlighted. User fills in the text then clicks the button again. Second blank should be highlighted but it skips right to the third blank. If you don't fill anything in, the next blank will be highlighted. If you highlight and then fill anything in, the next blank is skipped and the following blank is highlighted. Any thoughts? But my worst problem is with Mozilla. I get an error. It does not act like setSelectionRange(pos, pos+len(str)) is a valid function call. I receive the following error: "component returned failure code: 0x800004005 (NS_ERROR_FAILURE)[nsIDOMNSHTML TextareElement.setSelectionRange]" Here is my function: var win = window; var n = 0; var str = '______'; function FindBlanks() { var txt, i, found; win = tinyMCE.get('txtPolicy').getDoc(); if (str == "") return false; if (window.execScript) { txt = win.body.createTextRange(); //Find the nth match from the top of the page for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) { txt.moveStart("character", 1); txt.moveEnd("textedit"); } // If found, mark it and scroll it into view if (found) { txt.moveStart("character", -1); txt.findText(str); txt.select(); txt.scrollIntoView(); // n = i--; n++; } //Otherwise, start over at the top of the page and find first match else { if (n > 0) { n = 0; alert("End of document has been reached."); } //Not found anywhere, give message. else alert("No blanks found."); } } else { //document.getElementById('txtPolicy').setFocus; var ht = '______'; if (ht.length == 0) { alert('highlightText has zero lenth'); return false; } var str2 = document.getElementById('txtPolicy').value; var startPos = str2.indexOf(ht); if (startPos == -1) { alert('No blanks found'); return false; } document.getElementById('txtPolicy').focus(); document.getElementById('txtPolicy').setSelectionRange(startPos, startPos + ht.length); return true; if (n == 0) alert ("No blanks found."); } return false; } Can anyone help me with this?

Thanks Hello, I have build a tree view forum, I have used the iframe tag to import it to my wordpress blog . I have a script that determine the size of the iframe on load: Code: <script language="JavaScript">
<!--
function calcHeight()
{
//find the height of the internal page
var the_height=
document.getElementById('the_iframe').contentWindow.
document.body.scrollHeight;
//change the height of the iframe
document.getElementById('the_iframe').height=
the_height;
}
//-->
</script>
The problem with the script is that the forum(tree view forum) only shows topics. I have another script that displays the contents of any issue only while clicking (Void). In actual the contents of each issue is charging ahead - but the resize function of the Iframe script not see it. How do I fix it, that the size of the Iframe will change automatically? Thanks alot |
