How can I change an HTML input value's data type to integer?

Question

I\'m using jQuery to retrieve a value submitted by an input button. The value is supposed to be an integer. I want to increment it by one and display it.

//          


        

Answer 1

To convert strValue into an integer, either use:

parseInt(strValue, 10);

or the unary + operator.

+strValue

Note the radix parameter to parseInt because a leading 0 would cause parseInt to assume that the input was in octal, and an input of 010 would give the value of 8 instead of 10
