How do i trim in javascript or jQuery?

how do i trim using this

 $('#type_of_station').text()
开发者_如何转开发

the result is

>>> $('#type_of_station').text()
"pizza delivery system "

As you can see there is a space after the last word

jQuery: str = jQuery.trim(str);

JavaScript: str = str.replace(/^\s*/, "").replace(/\s*$/, "");

Use the JQuery.trim() function.
