无法在js中的条件语句中比较0

Question

well this is in node to be exact but, when i do the following conditional statement on a string of a length of zero or above zero, it will only ever do the condition if the string is not 0.

if(string.length == 0)
{
   console.log(string.length)
} else {
   console.log(string.length)
};

no matter what it wont respond if the string.length is 0. i have also tried:

if(string.length > 0)
{
    console.log('greater than zero')
} else {
    console.log('zero')
};

but with the same results. no matter what it wont respond if the string.length is zero. i have printed the string.length outside of the if/else statement, and have been able to have it print 0. why wont the conditional statement work in this case? why does it just not respond if the string.length == 0?

Answer 1

Seems to work. Fiddle here Firebug records a 0 if there is nothing in the <div>

Answer 2

如果字符串为0，我将获得空格。我通过执行string.trim（）解决了该错误。
