Compare input with minValue only when focus lost

[Benzolitz]

Building upon @loicfevrier 's Pull request (#3).

• Only compare the user input with the minValue, when focus is lost. Otherwise a positive minValue could lead to problems.
• use parseFloat for comparision. "9" > "10" = true / 9 > 10 = false
• check first if the value is nothing. Checking if a value even exists after using it is kinda strange to me.

Thanks (again) for the pull request.
Can you provide a configuration that will cause the error(s)?

Thanks in advance.

Point 1:

$('#txtTesting').jStepper({minValue: 10, maxValue: 20, minLength: 2});

After you typed in 10, try to change the number to 11. When I remove the 0 to add another 1, the script automatically changes the value to minValue. Only possiblities to change:

• Be faster than the script
• Copy & Paste the correct number
• overwrite the 0
• use mousewheel

Point 2:
I can't reproduce the error now, sorry. The problem was that I had a maxValue of 20 and when I typed in a 9 the script would change it to 20, because he would check if "9" > "20", which is true because both are strings.

Point 3:
Just a minor pet peeve of mine ^^.

strValue < o.minValue && strValue != ''"

You first check strValue < minValue and then check if strValue even contains something. The logical order makes no sense for me.

Example:

strValue = "", minValue = 5

your code: check if strValue < minValue AND then check if strValue even contains something.
my code: check if string Value contains something.
