i have test area in the jsp page for which i have put a java script to validate the max length of it.

but the problem is that as soon as cursor id focus on the tedt area it automatically takes some blank char

the code of jsp page is (the opening and closing of the HTML tags are recplaced by "&" sign)

<td>
<textarea name="projDesc" rows="4" cols="50"
on key up ="maxlength(this.form.projDesc,100)"><%=oListProjectBean.getDescription()%></textarea><span class="requi3Field">*</span></td>

and javascript is

function maxlength(field, maxlen) {
alert("hello1jaimin"+field.value.length);
if (field.value.length > maxlen){
//alert("hello"+field.value.length);
field.value = field.value.substring(0, maxlen);

}
}

Jaimin,
Are you filling the field with more than 100 characters from the description? What do you expect to happen in this case?

as soon as the cursor focuses on the the description text area it automatically takes 25 to 27 blank char.

which is displayed by the alert that i have put on the javascript.

what i want is the normal focus on the text area.......

Also, please be sure to use UBB code tags when posting code to the forums. Unformatted code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please read this for more information.
