输入键以使用php id乘以表单的情况下使用javascript提交表单

Question

I have separate reply form with each post with it's own php $id in same page. So I want to submit each reply with keyboard Enter key. I collect this javascript code below from here, but I cannot understand how apply it for each reply.

BN: Collected code not working also.

my form:

<form action="" method="post" class="repfrm'.$id.'" id="prepfrm">
<textarea name="replycom" id="replycom'.$id.'" class="replycom"></textarea>
<button type="submit" name="submit" id="'.$id.'" class="replyfrm">Post Reply</button>
</form>

Collected Script From stockoverflow:

$(".replycom").keyup(function(event){
   if(event.keyCode == 13){
       $(".replyfrm").click();
   }
});

Answer 1

Something like that:

Bind keypress to textarea and submit the closest form when press the key

$("textarea").keypress(function(event) {
    if (event.which == 13) {
        event.preventDefault();
        $(this).closest("form").submit();
    }
});

Answer 2

Try this script

 $(".replycom").keypress(function (e) {
        if (e.keyCode == 13) {
            $(this).parents('form').submit();
        }

    });

Change textarea to textbox and you press enter in textBox then it works which you want. Do not required jQuery code.

<form action="" method="post" class="repfrm'.$id.'" id="prepfrm">
   <input type="text" name="replycom" id="replycom'.$id.'" class="replycom">
   <button type="submit" name="submit" id="'.$id.'" class="replyfrm">Post Reply</button>
</form>
