I need a validation that contain enter space.

var addname = /^[0-9a-zA-Z\.,'";:& ]+$/;  
if(!(adres.value.match(addname))) {
   document.getElementById("ad").innerHTML="Feild Ruquired! only characters A-Z,0-9, a-z,and ',.;&:' are  acceptable";
   chk="false";
}

I use this code and it's working but when I press the enter button and write something in textarea field I get this error:

Feild Ruquired! only characters A-Z,0-9, a-z,and ',.;&:' are  acceptable

so I enter and write more description in a textarea field, like 

1-somethong
2-something etc.

You have to add an allowance for new lines in your regular expression A carriage return uses the invisible characters \r and a line break is \r\n.

So we just change your expression to:

var addname = /^[0-9a-zA-Z\.,'";:&\r\n ]+$/i;

And it should catch them fine. ( i added the i at the end to make it case insensitive as well.)

you can test and play with it Here.

Hop this helps.

  • Oh... so the form is trying to submit when you press enter instead of adding a return into the text field? Here is a tread about that issue. http://stackoverflow.com/questions/9671688/preventing-enter-from-submitting-form-but-allow-it-on-textarea-fields-jquery – TinMonkey Oct 22 '15 at 16:07
