substring on a non-object in jQuery.

Question

I need to substring a variable, and not an object, I know objects such as;

$("div#foo").text().substr(0,1);

But I need to do it on a non-object, for example a variable;

var foo = 'abc';
foo = foo.substr(0,1);

The second example won't work, because it's a non object. The actual problem is that I need to cut the last character off from a string, so is it possible to do this in jQuery on a non-object?

Answer 1

var foo = 'abc';
foo.substring(0, 1);

Answer 2

In Javascript, a String is actually also some kind of an object. As such, it has its own member functions, and substring() is one of them. Use the syntax RaYell provided to achieve what you want :-)

Answer 3

I think that maybe you are receiving that message ("foo.substring is not a function") because when you declared the foo variable you wrote $foo instead of var foo. That's the reason why it is interpreted as a jQuery variable instead of a javascript variable
