Javascript，将动态内容写入textarea

Question

I am programming a blog in php, for the record I've just started out but Im doing pretty good with this PHP but Javascript I don't really understand.

On my blog I would like people to comment and discuss.

What I want:

Every comment has an id that is displayed.

I want to click on it and then the Javascript should place it in the textarea for leaving comments.

Thats all.

Answer 1

(This answer uses jQuery.)

// getting a reference to the TEXTAREA element
var $ta = $("#new_comment textarea");

$(".comment").click(function() {
    var text = $(this).find(".text").text(); // depends of the structure
    $ta.val(text);
});

<div class="comment">
    <p class="author"> Peter </p>
    <p class="text"> Good article! </p>
</div>
