I want to get some textarea text and replace all bullet point html entities • with ·.
The usual approach str.replace(/•/g,"·"); doesn't work.
Any advice would be appreciated.

Are this bullet points encoded like this or they come from list elements?giker– giker2012-01-18 09:21:31 +00:00Commented Jan 18, 2012 at 9:21

When you're getting the text value back from the textarea, it has already been converted to its actual character. To do a string replacement on that string, either
- convert all characters to their html entity counterparts, then proceed with what you're doing or
- use the character in the regex directly.
Here's an example of the second approach.
var newText = oldText.replace(/•/g, "");
You can fiddle with an example here.
If you want to go with the first approach, see this question and its answers for ways to convert characters in a piece of text to their corresponding html entities.

The code presented removes the bullet points, and the jsfiddle code replaces them with the text “[DELETED]” but the principle is of course clear. For the operation in the question, the replacing string would be
"·" or, equivalently, "·". If the intent is to replace a character string like • if entered literally by the user, then it’s a different question.If you want to do this without jQuery:
var myTextarea = document.getElementById('id_of_your_textarea');
myTextarea.value = myTextarea.value.replace(/•/g, '·');
jQuery:
$("#myTextarea").val( $("#myTextarea").val().replace(/•/g, '·') );
.val() will get the value from an input element, .val('str') will set a value.
