String to int

[shaleen]

hi everyone

I am extracting values from the json files using store and model in sencha.
some of the values extracted are int. I want to perform operation on it(mathematical)......but it is a string.

How can i convert this string to int or is there any other way of doing mathematical operation on them.

This is coming from json file-
open_value=this.get('open');

This is the operation which i want to do
alert(open_value+12);

Suppose value of open_value = 30
then output should come 42 and not 3012 which is coming in present case

Your variable open_value is being interpreted as a string, and then the + 12 is treated as string concatenation. Try this:

alert(parseInt(open_value,10) + 12);

ExtJS does this for you.

Just specify a field type when you define your Model.
