Is there a way to use javascript or something within rsform! to limit the amount of characters in a textarea? I want to set a max of 100 characters

Ditto - same question only with limiting the number of words vs. characters in a textarea?

I have the same need. I have found some Javascript that will do it:
javascript.internet.com/forms/limit-textarea.html

I added the javascript to a .js file, uploaded to my server and added this to the Script called on form display. This will load the .js file into the HTML header
The problem is that rsform adds brackets around the form field name attribute, which throws off the javascript. So <textarea name=\"form[Field]\" will not work because of the brackets, yet this is what RSForm creates.

So this would all work if I could find a way to not use brackets in the name=\"\" attribute.

Is it possible to not use brackets in the name attribute?

From looking at the code, my guess is the developers are using the brackets to automaicaly put the data into arrays when it is processed... so I wonder if there is a way to tweak the JS to ignore/replace the brackets...

I got it working. I meant to post a reply to this topic but ended up creating a whole new topic! Sorry:

Ok, I got it working!
First, I used a different snippet of javascript, just because I liked this one better:
www.mediacollege.com/internet/javascript...imit-characters.html

#1) So copy this code into a file called limit.js
Code:



function limitText(limitField, limitCount, limitNum) {
if (limitField.value.length > limitNum) {
limitField.value = limitField.value.substring(0, limitNum);
} else {
limitCount.value = limitNum - limitField.value.length;
}
}




Save the limit.js file somewhere on your server.

#2) Create your form and the text area field you want

#3) While editing the text area field, add this code to the Additional Attributes field:
Code:


onKeyDown=\"limitText(this.form'],this.form.countdown,1500);\" onKeyUp=\"limitText(this.form'],this.form.countdown,1500);\"



In this case, replace Fieldname with the name of your field.

#4) In the field style, add this somewhere below the {field}:
Code:


<br />
<font size=\"1\">(Maximum characters: 1500)<br>
You have <input readonly type=\"text\" name=\"countdown\" size=\"3\" value=\"1500\"> characters left.</font>



#5) Save your field and add this code to the scripts tab for your form under \"Script called on form display\" --
Code:


$doc = &JFactory::getDocument();
$doc->addScript('/path-to-your-script-/limit.js');



#6) Save the form and that's it!

When a user types, they will be limited to 1500 characters and the form will tell them how many characters they have left.

Thanks for the help. Questions: 1. Can this be done for words instead of characters? 2. What is JFactory? I get an error that JFactory cannot be found. Thanks!

Hi Hearts,

Any luck in finding a way to limit the words instead of characters?

Thanks.
