Text Area Bytes Limit?
Jan 11, 2010
I just found the folloing script that limt the chars in a textarea field. As I am working with UNICODE ( I work in Brasil and our language is portugues whith a several special chars), I woukd like to do the same as the script but changing the limit to bytes. I am a javascript begginer, and found an other script that count the bytes in a string, but I didi not know how to implement it in the first script to limit it to yhe byte count,Here are the scrips:
1 - Chars limit:
Code:
<script language="javascript" type="text/javascript">
<!--
function max1(txarea){

Here is a script for limiting text area input. It also shows the remaining characters. Simply change the start value for "Characters remaining" to adjust the max length of the form.
<html>
<head>
<script type="text/javascript">
//Original Script By: Adam Matthews
//Date: 05/05/2005
//Posted at: http://www.codingforums.com
var max=0;
function showChar(obj)
{
var obj3=document.getElementById("char");
if(max==0)
{
max=obj3.firstChild.nodeValue*1;
}
len=obj.value.length;
var cur=max*1;
cur=cur-len;
if(cur<0)
{
var obj2=document.forms[0].elements['comm'];
var str=obj2.value.substring(0,max*1);
obj2.value=str;
showChar(obj2,max);
return false;
}
else
{
var obj2=document.getElementById('char');
var str=document.createTextNode(cur);
obj2.replaceChild(str,obj2.firstChild);
return true;
}
}
</script>
</head>
<body>
<form>
<textarea name="comm" cols="20" rows="3" value="" onkeyup="showChar(this);" onblur="showChar(this);"></textarea>
<br />
Characters Remaining: <span id="char">200</span>
</form>

like when we get the string object using Net Beans IDE and when we put "Object." , drop down will be displayed with available methods for that particular object. idea is to build a editor using java script.

1. When I have the "<textarea>" code lines in it put a text-area on the page, but it puts all of the code following that first text-area line into the text-area box and doesn't execute that segment of code.
2. When there is no "<textarea>" (for the sake of seeing if the rest of it worked) it doesn't check the survey.
I'm stumped and can't figure out what to do at this point Code and pictures follow:

I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right
<script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
[Code]....

Im working using the BEA Aqualogic CMS and have a a few pages with either videos or documents uploaded to them. There is a column displaying the filesize which is using the code below: file size:<pcs:value expr="item.Document.length"></pcs:value> kb The code "<pcs:value expr="item.Document.length"></pcs:value>" is the bit where it pulls the filesize from within the CMS. However, currently this is in bytes and i need this in kb. For arguments you can use 19968 as an integer to convert into bytes.

I have a form setup so that selecting a radio button opens a specific text field. The problem is if the user starts to enter information, then switches to a different radio button (perhaps they chose the wrong radio to start), the text they already started to enter on the previous textfield doesn't get cleared. This will be a problem later when inserting to sql.

As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page.
For Example:
Input- 512
Output - Austin, TX
The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen.

Would u pls let me know whether the following is possible or not: User can be able to insert text on a text-box or text-area(form) as usually we use text-area to do so. But I want to put some readonly text using an open and close tag
for example: <ro>This is readonly text</ro>insert your text here Can I be able to make the text inside <ro>..</ro> tag readonly, it means user can't be able to modify or delete this readonly text. readonly text length not fixed. only way to recognize the readonly text is the <ro> tag.

I have this script that gets the value of the selected radio button and then i put into a table from the id. I have over thrity of these and realized that if i didnt cut the values down to a certin size, it would completely destroy the table. I was wondering if there was any way to run the selected value from the radio group through the function(or something else that can cut it to a certin length) then display it in the table. i was thinking it might be easy to do the whole thing in javascript.
Everything above here works great, i just need to cut it to a certin lenght before its displayed
Im not sure what to put into the function to get it to do what is want echo trimStr(**************);?>

I want to be able to enter a value on a page (like 3.2), and then read
it as a 32-bit float and break it into it's individual bytes.
I've tried using bitwise operators, but they seem to convert the value
into an integer first, and i've tried using the toString() method to
convert it into a hex value so i can parse it, but that also seems to
first convert it into an integer.

I've been following this tutorial (and it works great)URL...Just cannot figure out how to make one of the Text Fields a Text Area with cols="45" rows="5".Every combination I've tried turns off the validation. I've already added completely different text fields from what are shown in the tutorial so I know how to change up the javascript I just can't get the Text Area right.

<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello, I would like to know if I can load a small text from a external source into a textarea. the external source is a php that will write some clean text depending on the vars received. I know load() can do the job for a div but I don't think it will work for a textarea.

I'm trying to 'wrap tags' around text in a text box.
<script language=javascript>
function insertFauxTags(fauxTag, e, endFauxTag)
{
var e = document.frmAddNewForum.txtTopicMessage.selected;
document.frmAddNewForum.txtTopicMessage.Value += fauxTag + e + endFauxTag;
}
</script>
And my form:
<form runat="server" id="frmAddNewForum">
<asp:textbox id="txtTopicMessage" runat="server" cssclass="formtext" rows="5" textmode="MultiLine" width="95%" style="width:95%"></asp:textbox>
</form>
And here's how I'm calling the function:
<a href="javascript:insertFauxTags('[p]' + e + '[/p]')"><img src="http://www.<%=strSiteName%>/images/parabutton.gif" border="0" alt="Paragraph" /></a>
When I run this in FF I get 'e' is not defined - any ideas?

I have a problem with XHR size limit. I want to transmit text information for page to a PHP script which saves it in a MySQL database but the data are cut off. When I reload the page the changes I made are gone. Firebug produces the following message:
... Firebug request size limit has been reached by Firebug. ...
This is my XHR function:
My question is: Is there a size limit in XHR POST requests? If yes how to disable it or is a browser issue?

I've also tried to insert it using this script :
