Hi,
Few months ago I wrote a blog post on this issue and how I implemented
this feature.
http://www.nirandas.com/post/max-length-property-for-textarea.aspx
Main difference is that instead of not allowing key down/key up on
textarea if the size exceeds, it removes the extra chars from the text.
txt.value = txt.value.substr( 0, size);

Hi: I have the following code to check the TextArea to make sure a
user doesn't enter more than 10 characters. It works but badly with a
screen reader. If I enter 11 characters it will keep typing but no
more characters are added to the box. Then when I try to open it again
I just hear a ping with left and right cursor. Up and Down cursor
reads the 10 characters but I can't delete anything using the delete
key, I am locked out of the box.
How do you JS folks handle a MaxLength situation that works well with
screen readers? Here is the code I am currently using.It took some
work to get it working but I am not happy with the way it reads for
screen reader users.
Overview:
<textarea name="ctl00$MainStarTrekContent$FormView1$OverviewTextBox"
rows="10" cols="20"
id="ctl00_MainStarTrekContent_FormView1_OverviewTextBox"
onkeydown="if(this.value.length>=10) return false;"
onkeyup="if(this.value.length>=10) return false;"
style="width:800px;">abc</textarea>
<br />
Note: These are bound TextBoxes inside a MS ASP.net FormView if that
colors your solution.
Thanks for any Ideas:
