how to remove a part of string within a string using jquery

Question

I'm developing a small app, when a checkbox is checked it's id value is added to a hidden field, when unchecked, it's id has to be removed from the hiddenfield value. I know how to add, but don't know how to remove. It's like say there is a string strValue="abcde"; how do I remove 'c' from the strValue using jQuery? Thank you.

Answer 1

You can use replace.

strValue.replace('c', '');

I would suggest two things, looking at jQuerys .Data() method for storing values, and at the very least making your list delimited by something such as a comma.

Answer 2

Try this, make sure you take the result of replace method into a new string. It does not modify the original string.

var str = "somestring";

str = str.replace('some', 'someother');
