Question

I have the following:

<textarea name="comment"><p>Good job.</p></textarea>

Using JavaScript, I’d like to replace “Good job” with “Here’s how I graded your assignment:”.

I’m not comfortable with string replacement yet.

Answer 1

A pure Javascript solution:

var myTextArea = document.getElementsByName("comment")[0];
myTextArea.value = myTextArea.value.replace("Good job", "Here's how I graded your assignment:");

It’d be better to give your textarea and id and select it using getElementById instead.
