You can get the text inside your span using text() method and parseInt() to convert it to number:

var rateVal = parseInt($("#rate").text(), 10);

You can do also this

var result = Number($("#rate").html());

But becareful to use Number functon, Please have look this discussion for difference between parseInt and Number.

What is the difference between parseInt(string) and Number(string) in JavaScript?, as Roko indicated.

@RokoC.Buljan now edited the answer with parseInt. – Suman Bogati Jan 25 '14 at 06:26
you should remove your answer, cause otherwise it's a duplicate of Felix's answer, and BTW you're missing the `radix` parameter. – Roko C. Buljan Jan 25 '14 at 06:30
Fexlix is using text(), and I used html(), does this consider as duplicate answer? – Suman Bogati Jan 25 '14 at 06:33
Almost, .html() is even the worse scenario, but now that you're using parseInt() makes no difference between your and Felix's. + You're still missing the parseInt radix parameter. – Roko C. Buljan Jan 25 '14 at 06:35
I just want to give another option, Does changing parseInt to Number prevent the deleting answer? – Suman Bogati Jan 25 '14 at 06:37
`Number()` only takes one argument, doesn't it? – nnnnnn Jan 25 '14 at 12:36
