Limit Text Area Input
Apr 5, 2005
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.

<head>
<script type="text/javascript">

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>
</body>

I am trying to create a text area input filed for user input, and i want to be able to allow the user to format thier text, just like the ones used in this user forum. I am writing my website in html, php, javascript and css with a MySql database. I am trying to understand how to create such an format-able text area for input.

I need to a code to do the following.
There is a Text Area that user can enter text. assume that user enter something and put a dot Following values should be populate in a drop down at the place where dot locate .
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.

I work within an application so I can not just code this field as a textarea. I have to work with what the applications renders.
I am trying to use javascript to change an input field to a text area.
I am having trouble just getting started on this. Doesn't anyone know if this is even possible?

I'm working on a simple feedback form (well not so simple for me) for the last page of my site.
In the text area I expect to get normal western text PLUS (or even just) Chinese xharacters
my question is how do you validate Chinese character input?

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:

[URL]
Example for FirstName data input: Characters a-z,A-Z, hyphen, space are permitted. 0-1, !@#$%^&*()- etc are not permitted.
The plugin looks great but I am not able to figure-out how to limit which characters an end-user is allowed to input. Not just which characters are permitted but also which characters are not permitted.

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>";

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'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 text area, I want that user's should not be able to enter a charaters in it. I want them to enter only numbers.I have written the code below to do this but it is not working as I think I am not calling the function right way.I am open to new suggestions as well, if I can show some alert to user if they enter character rather than no.

I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
<table>
<tr>
<td>
<input type="hidden" name="on1" value="Size" maxlength="200">Size</td>
[code].....
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.
